Font stacking printing on various craft products has a role, and silicone products are no exception. For lettering printing, most products are influenced by brand names and company logos, which mainly target appearance components. However, when customizing logos, one does not know their own needs and cannot describe the desired effect. Therefore, for silicone appearance lettering, let me briefly introduce the common processing methods of silicone product lettering technology!   Mold logo engraving is currently the most basic way of logo production, which is simple and clear with consistent concave and convex shapes. The main process is to wash out the empty space of the mold logo in the upper and lower molds during mold processing. If the logo needs to protrude, the position is dug out in the upper mold, and if it needs to be concave, the position is dug out in the lower mold. When the raw materials are placed, the product is filled in the logo area and vulcanized to form the desired logo shape. For example, if other logo colors are needed, the K position needs to be dug out in the mold core, and the logo needs to be separately vulcanized and placed in the main mold to make a color separated logo and obtain a two-color product.   Printing logos, in the early days of the printing industry, seemed to be a relatively niche industry. Some people were worried that the ink would fall off after prolonged use, and the effect of the printing screen could not be achieved. However, now that the technology in China's printing industry has matured, if you do not want a three-dimensional effect, you can choose to use the printing brush form. Currently, the printing industry is very popular, and it will not fall off after printing is completed. The clarity of the screen is already very precise, which completely improves the quality and effect that consumers are worried about!   Pad printing and color printing are mainly used to produce LOGO patterns of different colors and multiple colors. This method can be processed through several methods such as heat transfer printing and water transfer printing, which are complex and inefficient. However, the LOGO effect of the product may not disappoint you. Generally, excess silicone jewelry and multi-color silicone products are more commonly used. There are many processing methods for silicone products, and there is nothing you can't think of that can't be achieved. In addition, there are also many other logo processing methods, such as glue dripping, coating, sewing, and so on.

In modern industrial products, many basic things cannot be separated from the processing of molds. Many materials we see in daily life, such as hardware, plastic, silicone, and other punching materials, are made using different molds. Therefore, compared to many industry professionals, the importance of molds should be known. Similarly, in the silicone industry, it is no exception. Without molds and auxiliary tools, it is impossible to complete many of our products.   In the silicone product industry, molds are the key to the entire product, and all products must be produced using molds to meet the requirements. However, silicone is different from plastic and hardware grinding tools in that it can be molded for sample making, which makes many people puzzled whether to use 3D printing or directly use production molds for sampling. Today, we will explain the different processes and methods of molds. Due to the fact that silicone product materials belong to soft colloids and are not processed using hard adhesives, 3D printing is a drawback. However, with the maturity of 3D printing, the use of soft adhesives is gradually becoming more mature. However, the material and workmanship of 3D printed soft adhesives still cannot achieve the desired effect and texture of the finished product. While the structure alone is not a problem, the effect still needs to be evaluated through the production of molds and the processing of finished products. The bulk mold and sample mold are the processes we need to go through. Many customers' silicone accessories cannot meet the requirements in terms of assembly and appearance, and they dare not rashly open production bulk molds. Otherwise, they are worried that the structure of the mold will not be correct after opening, and the appearance effect will not meet the requirements, resulting in poor quality of the silicone product and difficult project progress. Therefore, in the early stage of production, in order to meet the customer's appearance and structure requirements and achieve a similar fitting effect, we need to open a small mold and create a sample mold for comparison. After achieving the desired effect, we can proceed with the production of bulk molds. The difference between the production mold and the large goods mold is that the large goods mold can produce many points in a the first mock examination, which can be more efficient in production and processing in mass production. The sample mold is used for the qualification requirements of experimental samples in the early stage. Their difference is that one is only used for sample making experiments, and the other is used for mass production of large goods. So many friends do not understand why it is not possible to directly use sample molds for mold production.

With the promotion and application of silicone products in daily life, more and more industries are using silicone as the main material for customized processing of product categories. However, many consumers are troubled by the defects and problems brought by different silicone materials and usage areas. One of the reasons is that the surface of silicone products turns white after stretching. Under what circumstances will the product appear whiter?   It is normal for silicone rubber products to turn white after stretching and twisting, but it may mislead some friends into thinking that turning white is a bad phenomenon. Why does the product turn white? Firstly, the raw material of silicone belongs to semi transparent white mist material, so the whitening of the product after stretching is mainly related to the raw material. Silicone materials are mainly divided into ordinary silicone, gas-phase silicone, medical silicone, and special silicone, and different grades of materials can be seen from stretching. The main factor causing the product to turn white is that it belongs to precipitated silicone rubber, and the material is mainly precipitated silica. This type of silica is mainly made from industrial water glass obtained by reacting quartz sand and soda ash at high temperatures, and is prepared into a dilute solution with water. After adding the compound precipitate under epoxy conditions, wash, dry, and crush to obtain precipitated silica. So the blurriness of its products is mainly due to the presence of a certain compound in the silicon molecular chain, which causes whitening during stretching. In addition to precipitated silica gel, there is also gas-phase silica gel, which is more prominent than precipitated silica gel. That is what we often refer to as food grade silicone material. It has higher purity and stronger molecular structure. It is made of silicon tetrachloride and gas fired silica, with a molecular fineness of up to 800-1000 mesh for silicon, while the molecular fineness of ordinary precipitated silica gel is about 400-600 mesh. However, gas-phase silicone does not appear white or foggy when stretched. So sometimes when we distinguish silicone, we can distinguish whether it belongs to ordinary silicone or food grade silicone. Generally, ordinary silicone gel undergoes fogging during molding and vulcanization by silicone rubber product manufacturers, while gas-phase silicone gel has superior performance, high raw material purity, and no whitening phenomenon during stretching and rebound.

In today's increasingly environmentally conscious world, environmental friendliness has become an important consideration when choosing materials. Who is better on the environmental track than PVC and silicone, two common materials? Today we will give you a deep analysis.   1. Analysis of the Environmental Protection Status of PVC. PVC, also known as polyvinyl chloride, is widely used in industry and daily life, such as plastic pipes, doors and windows, and wire sheaths. But its environmental issues cannot be ignored. During the production process, PVC requires the addition of plasticizers, stabilizers, and other additives. Some plasticizers, such as phthalates, have been shown to have a disruptive effect on the human endocrine system and may pose a health hazard. Moreover, PVC contains chlorine, which releases harmful gases such as hydrogen chloride during combustion, polluting the air and corroding equipment; Abandoned PVC products degrade slowly in the natural environment and may release harmful substances into soil and water bodies, affecting ecological balance.   2. The environmental advantages of silicone are fully demonstrated. The main components of silicone are silicon dioxide and organic silicon polymers, which have stable chemical properties and are non-toxic and odorless. It has passed ROHS certification, which means it does not contain harmful heavy metals such as lead, mercury, cadmium, etc. The production process of silicone is environmentally friendly, and the curing process does not produce toxic by-products, without the need to add harmful additives. From a usage perspective, it is resistant to high and low temperatures and will not decompose or release harmful substances even at extreme temperatures ranging from -60 ℃ to 250 ℃, ensuring high safety. Widely used in food contact and medical fields, such as silicone kitchenware, baby pacifiers, medical catheters, etc. After disposal, silicone can be recycled and reused, reducing resource waste and landfill waste; Even if naturally degraded, it will not produce harmful substances and is environmentally friendly.   If you are looking for environmentally friendly materials and pursuing a green and healthy lifestyle and production method, in most cases, silicone is the better choice. In the current emphasis on environmental protection, choosing more environmentally friendly materials is your contribution to the sustainable development of the earth.

Silicone and PVC (polyvinyl chloride) are widely used polymer materials in modern industry and daily life. From electronic product casings to household items, from medical equipment accessories to children's toys, their presence can be seen everywhere. However, despite both possessing a certain degree of flexibility and plasticity, they have many essential differences. A deeper understanding of the difference between silicone and PVC not only helps professionals make precise decisions on material selection, but also enables ordinary consumers to have a better understanding when choosing products. From the perspective of composition and basic characteristics, silicone is a highly active and environmentally friendly material, mainly composed of silicon dioxide. Its unique open porous structure endows it with excellent adsorption performance and high stability. Its chemical properties are stable, and it hardly reacts with any substance except strong alkali and hydrofluoric acid; PVC is polyvinyl chloride, which is polymerized by ethylene monomer under the action of initiators. It is a thermoplastic with low cost, good flame resistance, insulation and chemical stability. In terms of physical properties, silicone gel is soft and has a delicate touch, excellent flexibility and elasticity, good resilience, and can withstand multiple bends without deformation; PVC has a wide range of adjustable hardness, and can be transformed from a hard material to a soft material by adding plasticizers. However, even if adjusted to a soft material, its softness and elasticity are difficult to compare with silicone, and PVC has a relatively rough hand feel. For example, touching silicone kitchenware and PVC plastic products with your hands can clearly feel the softness and skin friendliness of silicone and the stiffness of PVC. In terms of chemical properties, silicone has strong resistance to ultraviolet radiation and can maintain stability even when exposed to sunlight for a long time; Outstanding high temperature resistance, capable of withstanding temperatures of around 300 ℃ without producing harmful substances in high-temperature environments. It can be used to make baking molds and other products that come into contact with high-temperature food. PVC has good chemical stability and can resist the erosion of many common chemicals, but its high temperature resistance is poor. It may start to deform at around 70 ℃ and may release harmful gases at high temperatures, making it unsuitable for high-temperature environments. In terms of quality control, Dibo Silicone has established a sound quality management and testing system, strictly controlling every link from raw material procurement, production process to finished product inspection to ensure that product quality meets high standards. At the same time, we focus on customer service, providing timely, efficient, and professional pre-sales, in sales, and after-sales services, tailoring solutions for customers, and providing technical support. With high-quality products and services, we have won the trust of many customers. Our products are not only popular in China, but also exported to Europe, America, Southeast Asia and other places. In summary, there are significant differences between silicone and PVC in terms of composition structure, physical and chemical properties, processing applications, and environmental safety. When selecting materials in practice, it is necessary to comprehensively consider factors such as specific usage scenarios, performance requirements, cost budgets, and environmental standards in order to make the most of them and achieve the best results.

In daily life and industrial applications, anti slip performance is a key consideration for many material choices. Silicone and rubber, as two common polymer materials, are often used in anti slip scenarios due to their good flexibility and grip. So, silicone anti slip or rubber anti slip?The answer to this question is not absolute and requires in-depth analysis from multiple dimensions.   From the perspective of material properties, rubber and silicone have their own anti slip principles. The molecular structure of rubber gives it a high coefficient of friction on its surface, especially natural rubber and some synthetic rubber, which have a soft and elastic texture and can tightly adhere to the contact surface. In dry environments, rubber can provide excellent anti slip effect. For example, traditional rubber soles are designed with complex patterns to enhance friction with the ground, effectively preventing slipping. However, in special environments such as humidity and oil stains, the anti slip performance of rubber will significantly decrease. When it comes into contact with water, the surface is prone to become wet and slippery. Long term exposure to grease may also cause swelling, leading to changes in physical properties. In contrast, silicone exhibits unique anti slip advantages. The molecular structure of silicone is stable, and its surface has a certain degree of hydrophilicity. Even in humid environments, it can form a tight adsorption force with the contact surface. At the same time, silicone material itself is insoluble in oil and grease, and can still maintain good anti slip performance in oily environments. In addition, the surface microstructure of silicone can be optimized through special processes, such as adding concave convex textures and micro nano level rough surfaces, to further enhance friction. Experimental data shows that the specially treated silicone material has a friction coefficient on wet glass surfaces that is more than 30% higher than that of ordinary rubber, and its anti slip performance is particularly outstanding in extreme environments.   In the practical application of anti slip materials, Dibo silicone has demonstrated strong technical strength and innovation capability. Dibo silicone can customize the anti slip performance of silicone according to different usage scenarios through self-developed surface treatment technology. For example, for bathroom anti slip pad products, DiBo silicone adopts a three-dimensional honeycomb texture design, combined with micro nano rough surface treatment, so that the anti slip pad can firmly adhere to wet ceramic tile surfaces, effectively preventing slip accidents. In the industrial field, DiBo customizes anti slip silicone components for mechanical equipment. Through a special chemical cross-linking process, the bonding strength between the material and different materials such as metal and plastic is enhanced, and the surface friction is optimized to ensure stability and reliability under complex working conditions such as high temperature and oil pollution. Whether it is silicone or rubber, their anti slip performance is closely related to the design and manufacturing process of the product. By optimizing surface texture and adding special anti slip particles, the anti slip effect can be further improved. Therefore, when choosing anti slip materials, in addition to considering the characteristics of silicone and rubber themselves, attention should also be paid to the specific design and usage scenarios of the product, and a comprehensive judgment should be made in order to select the most suitable anti slip product for safety protection.

Natural rubber: Under general wear conditions, natural rubber has good wear resistance. Especially in low-temperature environments below 15 degrees, its wear resistance is superior to that of styrene butadiene rubber. Styrene butadiene rubber: Under high temperature conditions, styrene butadiene rubber exhibits excellent wear resistance. At the same time, when the temperature is above 15 degrees, its wear resistance is also better than natural rubber. In addition, the benzene ring in styrene butadiene rubber contains conjugated double bond groups, which can absorb and distribute external energy, protect the macromolecular chain from damage, and thus improve wear resistance. Butadiene rubber: Under harsh conditions such as high speeds, polybutadiene rubber has the best wear resistance. The wear resistance of its vulcanized rubber increases with the increase of the content of cis chain links (1,4 structure). Polyurethane rubber: containing conjugated benzene rings, its wear resistance ranks among the top in various rubbers, more than 4 times higher than natural rubber and styrene butadiene rubber. However, it should be noted that its wear resistance will sharply decrease at high temperatures. Other rubbers, such as chloroprene rubber and nitrile rubber, also have good wear resistance and can be selected according to specific application scenarios.

1. In terms of molds Check the accuracy and fit clearance of the mold The excessive clearance between the mold cavity and the core is one of the important reasons for the occurrence of burrs. If the gap exceeds the minimum flash edge gap of silicone rubber during the molding process (usually around 0.01-0.02mm, depending on the performance and product size of the silicone rubber), the mold needs to be adjusted or repaired. For example, a professional mold grinder can be used to grind the mating surface of the mold and reduce the gap. Check if the parting surface of the mold is flat. If there is any unevenness, silicone rubber is prone to overflow from the parting surface under injection pressure and form burrs. Precision grinding machines can be used to adjust the parting surface to achieve a high flatness, generally requiring the flatness error of the parting surface to be controlled within 0.005mm. Optimize mold temperature control The mold temperature has a significant impact on the flowability and curing properties of silicone rubber. If the mold temperature is too high, the flowability of silicone rubber will increase, making it easier to produce burrs. The mold temperature can be appropriately reduced. For example, for general hot vulcanized silicone rubber products, the mold temperature can be controlled between 120-180 ℃, and the specific temperature should be adjusted according to the vulcanization characteristics of the silicone rubber and the thickness of the product. By installing a cooling system (such as setting up cooling channels inside the mold) to control the mold temperature, the occurrence of burrs can be effectively reduced.   2. In terms of molding process Adjust injection pressure and speed Excessive injection pressure is a common cause of flash. When silicone rubber is injected into the mold cavity with excessive pressure, it will force the silicone rubber to extrude from the small gaps in the mold and form flying edges. The injection pressure can be appropriately reduced, for example, for small silicone rubber products, the injection pressure can be reduced from the original 5-10 MPa to around 3-5 MPa, but it is necessary to ensure that the silicone rubber can completely fill the mold cavity. Injecting too quickly can also cause flying edges. Excessive speed can cause turbulence in the mold cavity, increasing the possibility of silicone rubber overflowing from the mold gap. Slow injection can be used, such as reducing the injection speed from 100-200mm/s to around 50-100mm/s. Control vulcanization time Excessive vulcanization time can cause silicone rubber to continue expanding within the mold cavity, thereby increasing the risk of flash formation. If the vulcanization time is too short and the product is not fully vulcanized, it can also cause difficulty in demolding, which may tear the product and produce burrs. The optimal vulcanization time needs to be determined through experiments based on the vulcanization system and mold temperature of silicone rubber. For example, for hot vulcanized silicone rubber, the vulcanization time is generally between 1-10 minutes, and the specific time should be based on the complete vulcanization of the silicone rubber and the product performance meeting the requirements.   3. In terms of silicone rubber materials Choose the appropriate silicone rubber material Different silicone rubber materials have different flowability and vulcanization characteristics. If silicone rubber with high fluidity is used, the flash problem will be even more severe. You can choose silicone rubber with moderate fluidity, such as high branched structure silicone rubber, which has relatively low fluidity. At the same time, attention should be paid to the hardness of silicone rubber. Silicone rubber with higher hardness is relatively less likely to produce burrs during the molding process. Check the quality of silicone rubber material Check whether the silicone rubber contains impurities or has deteriorated. Impurities may affect the flow and curing of silicone rubber during the molding process, leading to the formation of burrs. If silicone rubber deteriorates, its properties will change, such as faster or slower vulcanization speed, which will also affect the molding quality. Simple testing can be performed on silicone rubber, such as observing its appearance, measuring its viscosity, etc., to ensure that high-quality silicone rubber materials are used.

What are the functions of silicone gloves in the kitchen? Entering the modern kitchen of a family, a pair of brightly colored, smooth and shiny silicone gloves is quietly replacing the former thick cotton hand protectors and has become the new favorite in the pots, pans and other utensils. Once upon a time, our ancestors could only rely on layers of old cotton cloth to cautiously explore the safe gaps in the scorching heat. Now, silicone can wrap the hands and calmly face the flames and scalding temperatures.   Silicone, this once exclusive polymer material for industrial kitchens, has already shed its luxurious coat and infiltrated the kitchens of the mortal world. Its true magic lies in its extraordinary thermal stability - able to withstand 200 degrees of heat waves without cracking or becoming brittle, far from ordinary plastics daring to imagine. When your hands are wrapped in this flexible fortress to take out the crispy bread from the oven, or flip the oily frying pan, it's like passing through flames but still covered in armor, without any worries of burning. Silicone silently transforms into a loyal high-temperature shield, firmly protecting the safety of every touch of your fingertips on the hot cookware.   What is even more delightful is its unparalleled easy to clean nature. The awkward dilemma of oil stains and flour stubbornly adhering to the texture between thick fabrics like a spell in the past, can be instantly restored with just a rinse of water today, and that beautiful color is instantly restored. Not only that, its airtight shield like surface effectively isolates liquid from seeping into the interior, and from then on, the hot and humid annoyance of "wet wipes" in the kitchen naturally dissipates.   The flexible posture of silicone gloves provides the widest stage for the agile display of fingers. Whether it's the sweet and sour fish fillet that is flexible and hard to grasp, or the mold demoulding that needs precise control, the silica gel fits every inch of the curve like the second layer of skin, showing dexterity. Unlike those clumsy old-fashioned cotton gloves, which are as heavy as armor and almost numb to touch, silicone gloves can transmit sensitive heat to fingertips lightly, as if separated by a layer of fine yarn, allowing people to still feel the moderate temperature pulse.   Of course, we also need to acknowledge its slight limitations - such as the possibility of being scratched by the blade after long-term use, or small damages at the edges that may allow moisture to seep in. But these are far from insurmountable obstacles. High quality silicone products have repeatedly made breakthroughs in toughness. When we choose products with moderate thickness and superior craftsmanship, and carefully maintain them, their life can be accompanied for a long time.   The clever creativity in the kitchen is the light prelude played by technology for the ancient stove fire life. Silicone gloves convey the most essential desire of modern home kitchens with silent toughness: they not only protect the skin from scalding, but also make cleanliness easily accessible, and capture the most authentic temperature pulse for us in every fingertip touch, making the cooking rhythm smoother and more elegant.

It is gently reshaping the way this frost flavor is born in the kitchen with unexpected convenience and ingenuity. Seemingly ordinary and unremarkable ice grids, after material transformation, hide extraordinary life philosophies - transforming stubborn hard boards into soft forms, making trivial operations elegant in a moment. What kind of humanized craftsmanship is hidden behind the small silicone ice tray? Today, we will take you to understand the advantages of silicone ice trays.   The soft posture of Bingge is the first "caring care" bestowed by silicone. Food grade materials are not hard or brittle in the cold winter, maintaining their original flexibility and elasticity at minus 40 degrees Celsius. From now on, they will no longer be afraid of violent strikes - just slightly bend or gently push the bottom of the ice tray, and the crystal clear ice cubes will be like gently caressed petals, falling out cleanly. The expectation of drinking ice is no longer complicated. This flexible charm further surpasses the single functional barrier of silicone ice shelves. The curve design of the mold is no longer strict and cold. You can create various shapes of heart-shaped snowflakes, mini teddy bear ice cubes, and even let dessert experts transform into smooth ones by injecting chocolate slurry and allowing it to cool and solidify, resulting in exquisite snacks; Add a small amount of batter and instantly transform into a delicate cake. With silicone in hand, the creative realm of the kitchen suddenly expands. Silicone material responds to the tedious noise of the kitchen with a quiet and gentle touch: it is lightweight and can be folded and stored in the gaps of drawers without any hindrance, bidding farewell to the dominance of traditional ice trays occupying half of the refrigerator. Cleaning is also a relaxing moment for fingertips, with flowing water brushing past and leaving no trace of dirt; If there is food residue, it can be boiled in boiling water to restore cleanliness and freshness, unlike hard plastic crevices that hide dirt and make people worry. This clean and reassuring quality comes from non-toxic food grade certification and stable chemical properties from low to high temperatures. When fingertips touch the delicate touch, when ice melts into beloved drinks, silently interpreting a comforting sense of health care.   The silicone ice grid subverts the old tradition of ice making with its gentle curves, making even the most ordinary freezing process a light ritual at the fingertips.
