Silicone buttons include single point silicone buttons, remote control silicone buttons, conductive silicone buttons, mobile phone silicone buttons, light touch silicone buttons, transparent silicone buttons, keyboard buttons, password machine buttons, car buttons, film buttons, laser engraved buttons, reset buttons, home buttons, PC buttons, learning machine buttons, pose machine buttons, password machine buttons, digital product buttons, p+r buttons, etc.   In the production process of silicone buttons, especially when producing thinner buttons, the next step is to remove the edges, which sometimes makes it very easy to break. So what is the reason for this situation?   1. The temperature during molding is too high. Silicone buttons become brittle when the temperature is too high during molding, and are prone to cracking and defects after demolding. 2. The operation method during demolding is incorrect. When demolding, many mold makers have not received professional training or are not careful in their work. They do not follow strict operation instructions to demold, which can lead to the breakage of silicone buttons. 3. Incomplete vulcanization of silicone buttons. When the temperature of the silicone button molding mold is too low or the vulcanization time is too short, it will cause the product to adhere tightly to the mold and be difficult to demold. 4. The silicone material used is too poor. Some factories blindly reduce costs and use inferior silicone button raw materials, resulting in poor quality silicone buttons, poor rubber material, poor toughness, and memory rupture. 5. Poor release of silicone buttons during mold lifting can cause the product to break during the lifting process. 6. Mold cavities with rough surfaces or accumulated dirt are not conducive to demolding, and molds that are difficult to demold are prone to breakage.

Nowadays, the application of silicone products is very extensive in China, especially in kitchen supplies. Silicone kitchenware brings greater commercial and practical value. This is our continuous investment in research and development technology to develop lined silicone products, accelerate the development and progress of our own technology, and strengthen the development of high-performance and high use silicone products. Silicone kitchenware undoubtedly uses silicone as the raw material, and the main component of silicone is a natural ingredient that exists in sand, stone, and crystals. Silicone is like tempered glass that people usually see. It is non-toxic, colorless, odorless, and does not dissolve solvents other than water, strong alkali, and sulfuric acid. Its chemical properties are very stable, so silicone kitchenware is very environmentally friendly and zero polluting. Compared to other iron, stainless steel plates, and porcelain kitchen utensils, silicone kitchenware also has many beloved advantages. Silicone is a raw material for enzyme adsorption, which has high wear resistance, flexibility, corrosion resistance, temperature adaptability, and high temperature resistance. Therefore, it is not easy to produce difficulties such as rust, heat, and breakage during the entire process of use. In addition, silicone kitchenware also has high temperature adaptability, so it can be used in both hot and cold drinks in daily life. And it can also have the function of insulation and heat preservation in the cold winter, and in addition to insulation and heat preservation, it will not burn the hands of the user. People generally accept the use of silicone kitchenware, which is inevitable and a trend. Not only is silicone material so excellent, but also the benefits and convenience that silicone kitchenware brings to people's daily lives. The above is all about why silicone kitchenware is so popular.

Sealing of wires and cables: Silicone foam strips are used to seal the joints of wires and cables, which can prevent moisture and moisture from entering, avoid short circuits, leakage and other faults in wires and cables, and also play a buffering and shock-absorbing role, protecting wires and cables from external damage. Electrical product buffering: In some electrical products, such as televisions, speakers, etc., silicone foam strips can be used for buffering and fixing between components, reducing vibration and noise, and improving the sound quality and stability of the product.

1. Color change Color darkening When silicone rubber products are exposed to high temperatures for a long time, the organic compounds inside may undergo oxidation reactions. These additives will generate some colored substances during the oxidation process, causing the color of silicone rubber to darken. For example, in some industrial production environments, silicone rubber products used for sealing high-temperature equipment may gradually turn from white to light yellow or brown after several months of use. Ultraviolet radiation is also an important factor in causing discoloration of silicone rubber. The energy of ultraviolet radiation can cause certain chemical bonds in the molecular chain of silicone rubber to break, generating free radicals. These free radicals further trigger a series of chemical reactions, producing conjugated colored substances. Like some outdoor silicone rubber sealing strips, long-term exposure to sunlight will gradually darken the surface color, from light to dark. Yellow color This is mainly due to the chemical changes that occur during the aging process of additives in silicone rubber, such as certain organic silicone oils or silicone resins. These additives may undergo yellowing reactions, causing the entire silicone rubber product to appear yellowed. For example, some silicone rubber gaskets used in electronic devices may turn yellow during long-term operation due to the combined effects of internal heat and external light.   2. Fading If dyes and other coloring agents are added to silicone rubber products, these coloring agents may gradually decompose or be lost during the aging process. For example, some colored silicone rubber toys may gradually become dull and even show obvious fading after prolonged use and sun exposure. This is because the dye molecules in toys undergo changes in their chemical structure and color characteristics due to factors such as light and heat, ultimately leading to fading.

Can silicone products be used in high temperature or extreme environments? Silicone products are widely used in various industries such as medical, food, electronics, and automotive due to their excellent physical and chemical properties. However, many people have doubts about the performance of silicone products in high temperatures or extreme environments: can silicone products withstand high temperatures? Will it fail under extreme conditions?   High temperature resistance of silicone products Silicone is a polymer material, mainly composed of silicon dioxide. The high temperature resistance of silicone products mainly depends on their formula and manufacturing process. The following is the performance of silicone products in high temperature environments: Temperature resistance range The temperature resistance range of ordinary silicone products is generally -60 ℃ to 200 ℃. Specially formulated silicone products (such as high-temperature silicone) can withstand temperatures up to 300 ℃. Stability at high temperatures Silicone can still maintain its elasticity and mechanical properties at high temperatures, and is not easily deformed or melted. Silicone has good thermal stability and will not release harmful substances even when exposed to high temperatures for a long time. Application scenarios Silicone products are widely used in high-temperature environments, such as automotive engine seals, oven pads, hot water pipe seals, etc.   Performance of silicone products in extreme environments In addition to high temperatures, silicone products also perform well in other extreme environments: 1. Low temperature environment Silicone can maintain good elasticity and flexibility at low temperatures, and has excellent low-temperature resistance. The low temperature resistance range of ordinary silicone products can reach -60 ℃, and special formula silicone can even withstand lower temperatures. 2. Chemical corrosion environment Silicone has excellent corrosion resistance to most chemicals such as acids, bases, and salts. Silicone products are not prone to aging or failure in chemically corrosive environments. 3.

Aerospace Silicone products have stable performance in sealing and insulation components under extreme temperatures and environments.   Silicone products have become the preferred material in multiple industries due to their excellent high temperature resistance and extreme environmental resistance. Silicone products can perform well in high temperature, low temperature, chemical corrosion, and high humidity environments.

1. Raw material preparation: laying the foundation for quality The main raw material for silicone products is silicone rubber, which is a high molecular weight elastomer with silicon oxygen bonds as the main chain. There are many types of silicone rubber, which can be divided into high-temperature vulcanized silicone rubber (HTV) and room temperature vulcanized silicone rubber (RTV) based on their vulcanization characteristics and performance. Different types of silicone rubber are suitable for different product manufacturing. For example, high-temperature vulcanized silicone rubber has high strength and heat resistance, and is commonly used to manufacture industrial products with high performance requirements; Room temperature vulcanized silicone rubber has the advantages of easy operation and adjustable curing speed, and is commonly used in sealing, potting, and other scenarios. In addition to the silicone rubber matrix, various additives need to be added to improve the performance of silicone products. Common additives include vulcanizing agents, reinforcing agents, plasticizers, pigments, etc. Vulcanizing agent is a key substance that causes cross-linking reaction and forms a three-dimensional network structure in silicone rubber. It determines the vulcanization speed and degree of silicone products. Reinforcing agents can improve the strength and hardness of silicone rubber, and commonly used reinforcing agents include white carbon black. Plasticizers are used to increase the flexibility and processability of silicone rubber, making the product easier to shape. Pigments endow silicone products with rich and colorful colors, meeting the aesthetic needs of different consumers. In the raw material preparation stage, it is necessary to accurately weigh the silicone rubber and various additives according to the formula ratio and mix them thoroughly and evenly. This process is usually carried out in professional mixing equipment, such as open mixers or internal mixers. Through mechanical stirring and shearing, various raw materials are fully dispersed to form a uniform adhesive material, preparing for subsequent molding processes.   2. Forming processing: endowing the product with a shape The uniform adhesive obtained through the raw material preparation stage is then processed into semi-finished products with specific shapes in the molding process. There are various molding methods for silicone products, including compression molding, injection molding, extrusion molding, and liquid silicone injection molding. molding Compression molding is one of the most commonly used methods for molding silicone products. It is suitable for manufacturing products with complex shapes and high dimensional accuracy requirements. During the molding process, the rubber material is first placed into the preheated mold cavity, and then a certain pressure is applied through a hydraulic press to fill the cavity with the rubber material under high temperature and pressure, and undergo vulcanization reaction. After a period of pressure holding and vulcanization, open the mold and take out the product. The advantages of compression molding are high dimensional accuracy and good surface quality of the product, but the production efficiency is relatively low, making it suitable for small batch and multi variety production. injection molding Injection molding is an efficient and automated molding method. It heats and plasticizes the rubber material through the screw of the injection machine, and injects it into the closed mold cavity for rapid vulcanization and molding under high temperature and pressure. Injection molding has the advantages of high production efficiency, stable product quality, and the ability to achieve automated production. It is suitable for mass production of silicone products with relatively simple shapes, such as silicone buttons and sealing rings. Extrusion Extrusion molding is mainly used to manufacture silicone products with fixed cross-sectional shape and continuous length, such as silicone tubes, silicone strips, etc. During the extrusion molding process, the rubber material is extruded into the desired shape through the die of the extruder under the action of the screw, and then undergoes vulcanization treatment to shape it. Extrusion molding has the advantages of high production efficiency and continuous production, which can meet the needs of large-scale production. Liquid silicone injection molding Liquid silicone injection molding is a new molding technology developed in recent years. It uses liquid silicone rubber as raw material, and precisely injects the liquid silicone rubber into the mold cavity through a dedicated liquid silicone injection machine, rapidly vulcanizing and forming at low temperatures. Liquid silicone injection molding has the advantages of fast molding speed, high product accuracy, and the ability to achieve complex structural molding, especially suitable for manufacturing silicone products in medical, food, and other fields that require high hygiene.   3. Sulfurization treatment: key to improving performance Sulfurization is a key step in the production process of silicone products, which determines the physical and chemical properties of silicone products. During the vulcanization process, the molecular chains of silicone rubber undergo cross-linking reactions under the action of vulcanizing agents, forming a three-dimensional network structure, thereby endowing silicone products with properties such as elasticity, strength, and heat resistance. The vulcanization method used in different molding methods also varies. Compression molding and injection molding usually use hot vulcanization method, which heats the mold to a certain temperature, causing the rubber material to undergo vulcanization reaction at high temperature. Liquid silicone injection molding often adopts low-temperature rapid vulcanization technology, which achieves rapid vulcanization at lower temperatures by adding special vulcanizing agents and catalysts, thereby shortening the production cycle and improving production efficiency. The vulcanization time and temperature are important factors affecting the vulcanization effect. Short vulcanization time and incomplete vulcanization reaction can affect the physical and chemical properties of the product; If the vulcanization time is too long, it will lead to over vulcanization of the product, resulting in problems such as decreased elasticity and brittleness. Excessive sulfurization temperature can cause defects such as bubbles and burning on the surface of the product; If the vulcanization temperature is too low, the vulcanization speed will be slow and the production efficiency will be low. Therefore, in the production process, it is necessary to accurately control the vulcanization time and temperature based on factors such as the type of silicone rubber, the shape and size of the product, etc., to ensure the quality of the product.   4. Post processing steps: Improve product details The semi-finished silicone products obtained after molding and vulcanization treatment require a series of post-processing steps to become the final product. Common post-processing procedures include trimming, cleaning, inspection, and packaging. Trimming During the molding process, due to factors such as the mold clamping line, there may be some excess adhesive residue at the edges of the product. The trimming process is to remove these excess adhesive edges, making the edges of the product smooth and neat. There are two methods for edge trimming: manual trimming and mechanical trimming. Artificial edge trimming is suitable for products with complex shapes and high precision requirements, but the production efficiency is low; Mechanical trimming is suitable for products with regular shapes and large batches, and has the advantages of high production efficiency and stable trimming quality. clean Silicone products may be contaminated with impurities such as oil and dust during the production process, and require cleaning treatment. The cleaning methods include water washing, solvent cleaning, etc. Water washing is a commonly used cleaning method with advantages such as low cost and environmental friendliness. However, for some products with heavy oil stains, solvent cleaning may be required. The cleaned products need to be dried to ensure their quality. test Inspection is an important step in ensuring the quality of silicone products. During the inspection process, it is necessary to conduct comprehensive testing on the appearance, size, physical properties, and chemical properties of the product. Appearance inspection mainly checks whether there are defects such as bubbles, cracks, and missing materials on the surface of the product; Dimensional inspection uses measuring tools to check whether the dimensions of the product meet the design requirements; Physical performance testing includes testing of indicators such as hardness, tensile strength, tear strength, etc; Chemical performance testing mainly tests whether the product meets relevant environmental standards and hygiene requirements. Only products that have passed strict inspection and are qualified can proceed to the next process. package Packaging is the final process in the production of silicone products. Appropriate packaging not only protects products from damage during transportation and storage, but also enhances the product's image and market competitiveness. The selection of packaging materials should be determined based on the characteristics and usage requirements of the product. Common packaging materials include plastic bags, paper boxes, wooden boxes, etc. During the packaging process, it is also necessary to label the product name, specifications, model, production date, and other information on the packaging for consumers to identify and use.

Screen printing is the process of stretching silk fabrics, synthetic fiber fabrics, or metal wires onto a mesh frame, and using manual coating or photochemical plate making methods to produce screen printing plates. Modern screen printing technology uses photosensitive materials to create screen printing plates through photographic plate making methods (making the screen holes in the graphic and textual parts of the screen printing plate through holes, rather than blocking the screen holes in the non graphic and textual parts). During printing, the ink is transferred to the substrate through the mesh holes of the graphic and text parts by the pressure of the scraper, forming the same graphic and text as the original. Screen printing equipment is simple and easy to operate, with simple printing and plate making, low cost, and strong adaptability. Screen printing has a wide range of applications, including color oil paintings, posters, business cards, binding covers, product labels, and printed textiles. Screen printing is also the most common surface character process in our silicone products, among which silicone buttons and silicone toys use this process more widely. According to the character design, adjust the oil difference color, and then use the positioning fixture and screen to print the required characters. Some parts may feel convex when touched by hand, which requires careful experience. Silk screen printing is a very important process in the silicone product industry. During the operation, it is necessary to pay attention to whether the surface of the silicone product is clean, the baking temperature and time after silk screen printing, and especially not to use low-quality silk screen ink or other materials to replace silk screen ink in order to save costs. This will lead to the occurrence of batch defects.   Strong printing adaptability, thick ink layer, strong three-dimensional sense, rich texture, strong light resistance, bright color, printing area, can be summarized as follows: 1. Screen printing can use various types of ink. Namely: oil-based, water-based, synthetic resin emulsion type, powder and other types of inks. 2. The layout is soft. The screen printing layout is soft and has a certain degree of elasticity, which is not only suitable for printing on soft items such as paper and fabric, but also suitable for printing on hard items such as glass, ceramics, etc. 3. Screen printing has low embossing force. Due to the low pressure used during printing, it is also suitable for printing on fragile objects. 4. The ink layer is thick and has strong coverage. 5. Not limited by the surface shape and area size of the substrate. As mentioned above, screen printing can not only print on flat surfaces, but also on curved or spherical surfaces; It is not only suitable for printing on small objects, but also for printing on larger objects. This printing method has great flexibility and wide applicability.

Extrusion molding is used to produce various silicone products. In the production process of silicone products, extrusion molding has become one of the important methods for manufacturing various silicone products due to its high efficiency, flexibility, and customizability. From simple rectangular silicone tubes to complex braided tubes, two-color tubes, etc., extrusion molding technology not only enriches the types of silicone products, but also greatly meets the needs of different industries and application scenarios.   Squeezing, as the name suggests, is the process of extruding mixed silicone rubber raw materials into products with regular shapes through molds at a certain temperature and pressure using an extruder. The core of this process lies in the design of the mold, and different molds can produce silicone products with different shapes. For example, common silicone tubes, sealing strips, foam strips, etc. are all manufactured using extrusion molding technology. These products are widely used in various fields such as healthcare, food, electronics, and construction due to their excellent elasticity, weather resistance, and chemical stability.   In the medical field, silicone tubing is often used as a catheter, drainage tube, etc. in medical devices due to its non-toxic, odorless, and biocompatible characteristics. Extrusion molding technology can produce silicone tubes with precise inner and outer diameters and uniform tube walls, meeting the strict requirements for product quality and accuracy in the medical field. Meanwhile, the flexibility and corrosion resistance of silicone tubing also make it an ideal choice for medical processes such as hemodialysis and infusion.   The food industry also relies on silicone products produced by extrusion molding technology. Silicone sealing strips, silicone gaskets and other products are often used in food packaging, food machinery and other occasions due to their excellent temperature resistance and food grade safety standards. These silicone products not only effectively prevent food leakage and contamination, but also maintain stable performance in harsh environments such as high temperature and high pressure.   Extrusion molding technology also plays an important role in the fields of electronics and electrical engineering. For example, products such as silicone braided tubes and two-color tubes are often used for insulation protection of wires and cables due to their good insulation, high temperature resistance, and flexibility. These silicone products not only improve the safety performance of wires and cables, but also enable them to maintain good conductivity and service life in complex environments such as bending and twisting.   In addition, extrusion molding technology can also produce foam silicone products such as foam strips, foam tubes, etc. These foam silicone products are often used in fields such as automotive interiors and building soundproofing due to their lightweight, soft, and sound-absorbing properties. By adjusting the type and amount of foaming agent, foam silicone products with different densities and hardness can be produced to meet the needs of different application scenarios.   It is worth mentioning that extrusion molding technology is not only suitable for the production of simple rectangular silicone products, but can also produce silicone products with more complex shapes and diverse functions through innovative mold design. For example, using co extrusion technology, multiple colors of silicone materials can be extruded simultaneously to form two-color or multi-color silicone products. These products not only have a beautiful appearance, but can also be customized according to individual needs to meet the diverse needs of consumers.   In addition to the application fields mentioned above, extrusion molding technology also plays an important role in many other fields. For example, in toy manufacturing, silicone extruded products have become an ideal choice for children's toys due to their soft, safe, and non-toxic characteristics; In the manufacturing of sports equipment, silicone extruded products are widely used in fitness equipment, sports protective gear, and other products due to their wear resistance, slip resistance, and good elasticity.   The application range of extrusion molding technology in the production of silicone products is wide and diversified. By adjusting the design of molds, the formula of raw materials, and the process parameters during production, silicone products that meet the needs of different industries and application scenarios can be produced.

The minimum order quantity for customized silicone products is generally high. In today's era of increasing personalized demand, silicone products are widely used in various industries due to their excellent physical properties, chemical stability, and environmental protection characteristics. Silicone products are everywhere, from tableware and cup lids in daily life, to protective covers and sealing rings in electronic products, to catheters and instrument accessories in the medical field. However, for customers who want to customize silicone products, a common issue is the minimum order quantity.   Minimum order quantity requirement for customized silicone products The minimum order quantity for customized silicone products is not fixed and is influenced by various factors, including but not limited to product complexity, mold costs, production processes, and manufacturer policies. Generally speaking, the minimum order quantity for customized silicone products ranges from a few hundred to several thousand pieces, but the specific number still needs to be negotiated based on actual needs.   Product Complexity Product complexity is one of the key factors affecting minimum order quantity. If the customized silicone product has a complex structure, such as multiple components, fine textures, or complex mold structures, the development and production costs of the mold will correspondingly increase. In order to share these costs, manufacturers often set higher minimum order quantities. On the contrary, for silicone products with simple structures and low mold costs, the minimum order quantity may be relatively low.   Tooling Cost Mold is the core tool for the production of silicone products, and its cost directly determines the production cost and minimum order quantity of the product. Generally speaking, the development cost of molds is relatively high, especially for complex molds. Therefore, in order to reduce the impact of mold costs on product prices, manufacturers usually set a higher minimum order quantity to share mold costs. However, with the advancement of mold technology and the intensification of market competition, some manufacturers will also provide mold sharing or leasing services to lower the minimum order quantity threshold for customers.   Production process The production process is also an important factor affecting the minimum order quantity. The production process of silicone products includes various methods such as injection molding, extrusion, and rolling, each of which has its specific production efficiency and cost. For example, injection molding technology is suitable for producing silicone products with complex structures and high precision requirements, but the production efficiency is relatively low, so the minimum order quantity may be relatively high. The extrusion process is suitable for producing long or tubular silicone products with high production efficiency, but the minimum order quantity may be relatively low.   Manufacturer Policy The production capacity and market strategy of different manufacturers can also affect the setting of minimum order quantity. Some large manufacturers have advanced production equipment and rich production experience, which can undertake large-scale customization needs, so the minimum order quantity may be relatively low. Small manufacturers or startups may need to set higher minimum order quantities to ensure production stability and profitability due to production capacity and financial constraints. In addition, some manufacturers will adjust their minimum order quantity policies based on market demand and competitive trends to attract more customers.   How to reduce the minimum order quantity for customized silicone products? For customers who want to reduce the minimum order quantity for customized silicone products, they can start from the following aspects: Choosing a suitable manufacturer: Choosing a manufacturer with rich production experience and advanced production equipment can reduce production costs and minimum order quantity thresholds. Optimizing product design: By optimizing product design, simplifying product structure, and reducing mold development costs, the minimum order quantity can be lowered. Batch procurement: If conditions permit, it is possible to consider purchasing together with other customers or partners to reduce the minimum order quantity through batch procurement. Long term cooperation: Establish a long-term partnership with manufacturers to reduce the minimum order quantity requirement for a single order through sustained and stable orders.  

Why does my silicone product deform and stop bouncing after stretching back and forth? "This question has puzzled many friends, and currently, in addition to silicone bracelets, there are also many silicone products that have this phenomenon. Instead of rebounding after stretching, they show foggy patterns! So what is the truth behind this reason? For processing, many people know that every industry requires a rush to produce silicone rubber products, and the processing time is no exception. Therefore, the processing time has become the main factor for the deformation and non elasticity of this product. For silicone wristbands, which are relatively thin, if the molding time is too early during high-temperature vulcanization, the product will definitely become soft. Therefore, many silicone manufacturers did not consider that the time cannot be reduced casually during processing, and reduced the molding time of the product in order to meet production capacity, resulting in the product becoming soft and immature! Secondly, there are reasons related to the raw materials and vulcanizers. Sometimes, due to errors in the formulation of silicone raw materials and different mixing methods, the tensile rebound strength of the product is insufficient, resulting in large deviations in the raw material formulation and non rebound of the product. Secondly, the fixing effect of the vulcanizing agent is good or bad, and factors such as whether the vulcanizing agent is evenly mixed with the rubber material, whether the proportion is symmetrical, etc. may all affect the tensile rebound performance of the product! The main reasons for the deformation, stretching, and non elasticity of silicone products mentioned above, as well as the softening of the products, are mainly due to these factors. In addition to silicone wristbands, thinner products and thin strip products can also experience similar phenomena!
