Many people who have come into contact with silicone products know that some silicone products are prone to sticking to dust. So why do silicone products prefer to stick to dust? I believe friends who have used silicone products will have this question, especially the commonly seen silicone phone cases, silicone wallets, etc. in our daily lives, which are often prone to dust and difficult to clean. So, what are the reasons why silicone products stick to dust? In fact, the adsorption force of silicone products is a constant characteristic of silicone materials. Most silicone products have some dust adsorption function, but some silicone products undergo special processes before leaving the factory to make them non stick to dust. For example, in the production of silicone products, they generally need to be treated with oil spray. After the oil spray treatment, silicone sleeves and other silicone products will not be dusty, even if accidentally dropped on the ground, they will not easily get dusty. Therefore, when purchasing some consumer goods, you can choose some silicone products that have been treated with oil spray, so that they have a good grade in terms of feel and texture. Industrial accessories or electronic accessories are simple silicone products. There's no need to be so particular, So everyone still needs to refer to it when selecting silicone products.

1. Verify the feasibility of product design and structureDiscovering design flawsSilicone material is soft and elastic, and many structures that appear reasonable on the drawing may have problems such as uneven wall thickness, inability to demold due to inverted buckles, and improper placement of parting lines after actual molding.Sample molds can expose these risks in advance at a lower cost, avoiding huge losses caused by directly opening large molds.Verify assembly relationshipsSilicone parts usually need to be matched with plastic shells, metal parts, PCB boards, etc. The physical object made from the sample mold can be tested during actual installation to confirm whether the size fit, button stroke, sealing effect, etc. meet the standards. 2. Confirm material and process parametersMaterial selection verificationSilicone with different hardness (Shore A 30~80) has significant differences in shrinkage, flowability, and resilience.The actual shrinkage rate can be tested through sample molds, providing accurate data for compensating the cavity size of formal molds.Exploration of Process WindowThe parameters such as vulcanization temperature, time, and pressure have a significant impact on the appearance and performance of silicone products.The sample mold stage can optimize the process curve, determine the optimal production conditions, and reduce the debugging time and scrap rate during formal mass production.3. Evaluate appearance and feelSurface treatment effectSurface treatment processes such as spray painting, laser engraving characters, and silk screen patterns need to be validated on real products.Sample molds can be used to create templates with various surface treatments for customers to confirm before finalizing.Touch and operation experienceFor products such as remote control buttons and sealing rings, indicators such as press rebound feel and compression permanent deformation must be accurately evaluated through physical experience. SummaryThe essence of opening sample molds is to trade controllable small costs for design certainty and production reliability. It is not an unnecessary step, but a risk buffer zone connecting the design drawings and mass production molds, especially for materials such as silicone that are sensitive to mold accuracy, material properties, and process parameters. It is an essential step.

With the advancement of technology and the rapid development of the economy, in recent years, silicone materials have been widely used in various industries, especially in the application of maternal and child products, replacing plastic and glass materials. It is healthy, environmentally friendly, non-toxic, and odorless. Food grade materials can be used for baby bottles, dental implants, toys, etc. Medical grade silicone material can be implanted into the human body and is biocompatible. The high-quality characteristics of silicone make it suitable for all aspects of our lives. 1. Silicone is a material with a feeling similar to human skin, and a good baby silicone product should first have a good hand feel. Here we take a silicone baby bottle as an example. When feeding a baby, the baby's cute little hands hold the bottle, and the touch of the bottle on the baby is like a mother's loving touch. After the baby is born and leaves their original growth environment, the baby lacks a sense of security. Some babies often cry and make us feel helpless as new parents. However, silicone baby products that feel like a mother's touch give babies this sense of security. Therefore, good baby silicone products are beneficial for the development of babies in all aspects. This is also incomparable to other materials of milk bottles. 2. Silicone milk bottles should be easy to use. Disassembly and assembly should be convenient, universal, and interchangeable with other pacifiers and baby bottles. Some silicone baby bottles are now impractical to disassemble and assemble. Install card slots and set card patterns between the silicone and the plastic cover in the middle. The most important aspect of a bottle is its practicality and convenience. Performance and material of baby silicone products1. If the surface of real silicone rubber is not specially treated, it will feel relatively smooth to the touch because there is a layer of oily substance on the surface layer2. Fake silicone rubber is prone to deformation, while real silicone rubber has good rebound and is not easily deformed after pulling and rebounding.3. Good silicone has no odor and does not soften or change color when exposed to heat.4. Cut off a little bit of silicone and burn it with fire. The edge of the fake silicone rubber wristband is black after being burned. The fake silicone rubber burns with an open flame, producing black smoke and a foul odor. But for real silicone, regardless of the color of the silicone, the burning edge is white, and the burning residue is powder. And the real silicone rubber wristband burns like carbon, with even flames. White smoke, odorless.5. Look at the resilience of silicone products, high-quality silicone products have good resilience. Silicone material itself has good wear resistance, therefore, the surface of silicone products has the ability to resist wear and tear. Generally speaking, high-quality silicone products will not erase surface text, color, etc. due to external factors. On the contrary, the text, characters, and logos on the surface of inferior silicone products are more likely to fall off. High quality silicone products have a bright color, and after special processing, the surface is non sticky, odorless, soft, and has a good hand feel.6. Silicone products have high tear resistance, long service life, and are not easily affected by external environmental interference. Generally speaking, high-quality silicone products are less prone to cracking during the tearing process, while low-quality silicone products are more prone to cracking. When subjected to force, low-quality silicone products will quickly expand and crack from the crack.7. When silicone products are subjected to alternating stress (or strain) effects, the phenomenon of changes in the structure and function of the data is called fatigue. The scene of silicone product damage caused by the process of fatigue is called fatigue damage. So fatigue resistance is also one of the ways to distinguish the quality of silicone products.

In many fields such as industrial production, household daily use, electronic accessories, etc., waterproof performance is one of the core indicators to measure the quality of silicone products. Waterproof silicone parts, with excellent sealing characteristics, have become key accessories to solve equipment water leakage and material moisture problems. The reason why silicone products have excellent waterproof performance lies in the molecular structure and physical properties of their material itself. Firstly, silicone belongs to the category of polymer elastic materials. After curing, its structure is dense and free from the problem of fine pore penetration. It can effectively block the invasion of moisture and water vapor, and maintain stable waterproof sealing effect in both room temperature and high and low temperature environments. Secondly, high-quality silicone material has extremely strong weather resistance, and long-term exposure to environmental factors such as water, humid air, and ultraviolet radiation will not cause aging, cracking, deformation, and other problems. Its waterproof performance will last for a long time without deterioration. At the same time, silicone products can adjust their hardness and elasticity according to their usage scenarios. After compression and bending, they can quickly return to their original state and tightly connect with the bonding surface, further improving the waterproof sealing effect. Whether it is electronic silicone accessories, bathroom silicone seals, or outdoor waterproof silicone sleeves, they can meet the waterproof needs of different scenarios.For users with customized needs, mastering the processing techniques of waterproof silicone parts is essential to maximize the waterproof performance of the product. In the early stage of customization, it is necessary to clarify the product's usage environment, including parameters such as water pressure, temperature, and contact medium, in order to select silicone raw materials corresponding to food grade, industrial grade, high temperature resistance, etc., and ensure the basic waterproof performance from the source. Mold design is a key step in customizing waterproof silicone parts, requiring precise control of dimensional tolerances and sealing structures. The use of integrated molding technology reduces splicing gaps and avoids water leakage problems caused by structural defects. During the processing, it is necessary to strictly control the vulcanization temperature and time to ensure that the silicone material is completely cured, improve the density of the material, and optimize the sealing effect through surface treatment technology to ensure that the waterproof performance meets the usage standards. In addition, waterproof testing is required during the customized sampling stage, and process parameters are adjusted based on the test results to ensure stable performance of mass-produced products.The application scenarios of waterproof silicone parts are very wide, ranging from mobile phone waterproof silicone covers and bathroom sealing rubber rings to industrial equipment waterproof silicone accessories and underwater instrument silicone seals, all of which rely on high-quality waterproof silicone materials. When customizing, users should not only focus on processing techniques, but also choose manufacturers with professional production qualifications and rich experience to ensure that raw materials are environmentally friendly, processes meet standards, and testing is complete. Silicone products have inherent waterproof advantages due to their dense structure, high elasticity, and weather resistance. Customized waterproof silicone parts require a combination of various skills such as raw material selection, mold design, and process control to create high-performance waterproof products. Understanding these knowledge can not only help users clearly understand the waterproof characteristics of silicone, but also avoid detours in the customization process, and customize waterproof silicone parts that meet their own needs and have reliable quality.

In the process of customizing silicone products, material selection is the core link that determines product performance, usage scenarios, and final costs. Many users are not clear about the classification and differences of silicone materials, either blindly choosing high priced materials causing waste, or choosing low-priced materials that do not meet the usage standards. This article focuses on how to choose customized materials for silicone products, as well as the price differences corresponding to different materials, to help you accurately match needs, control budgets, and make cost-effective customization decisions. There are various types of silicone materials, mainly divided into three categories based on performance and application scenarios: industrial grade silicone, food grade silicone, and medical grade silicone. In addition, there are special modified silicone materials such as high temperature resistance, anti-static, conductivity, and high tensile strength. There are significant differences in environmental standards, temperature resistance range, hardness, elasticity, and safety among different materials, and their applicable industries are also different. The core principle of selecting materials is to match the usage scenario, meet safety and performance requirements, and not blindly upgrade or lower standards.Industrial grade silicone is the most basic silicone material, mainly used for non-contact human and non food contact scenarios such as electronic accessories, industrial sealing, shock absorption, dust prevention, etc. It has good insulation, aging resistance, and sealing properties, and its price is the lowest among the three types of materials. It is suitable for mass production and low-cost industrial product customization, with outstanding cost-effectiveness. Food grade silicone meets national food safety standards, is non-toxic, odorless, heat-resistant, corrosion-resistant, and can directly come into contact with tableware, mother and baby products, kitchen utensils, etc. It has higher safety and is priced higher than industrial grade silicone. It is the preferred material for the catering, mother and baby, and home appliance industries. Medical grade silicone has the strictest requirements, with biocompatibility, non allergenicity, non irritation, and is mostly used in medical consumables, beauty equipment, and human contact products. Its production process and testing standards are higher, so its price is also the highest.In addition to grade differences, silicone hardness, density, and special features can also affect customization prices. Conventional hardness silicone is moderately priced, while ultra-high or ultra-low hardness silicone requires special blending, which will increase the cost accordingly; Modified silicone with high temperature resistance of over 300 ℃, flame retardancy, and conductivity, due to more complex raw materials and processes, is priced higher than ordinary silicone. When customizing, the manufacturer will recommend suitable materials based on your usage scenario, such as food grade for mother and baby products, medical grade for medical products, and industrial grade for ordinary industrial seals.Choosing silicone material correctly can ensure product quality and usability, while also avoiding budget waste. If the wrong material is selected, the product may not meet the standard and cannot be used, and there may be safety hazards, resulting in rework and additional costs. It is recommended to clarify the usage environment, contact medium, safety standards, and temperature resistance requirements before customization, communicate with the manufacturer to confirm the material scheme, and then compare the corresponding quotation.

After the production of silicone products, there are many post-processing steps that can make the silicone products look more delicate in both feel and appearance. Today, we will introduce a silicone oil spraying process and the advantages of the sprayed product. The tactile oil sprayed on silicone products is also known as silicone matte oil or silicone matte oil. In fact, many silicone products require surface spray treatment. Silicone products that have undergone spray treatment generally have the following advantages. 1. The surface of the silicone product after spraying is relatively smooth, and it feels very delicate to the touch, perfectly solving the rough and astringent feeling of silicone products after molding. 2. Silicone products are prone to static electricity during the rubber mixing and molding process, which can easily adsorb dust during later use. Spraying a layer of hand feel oil can greatly reduce static electricity and avoid dust adsorption. 3. Silicone products sprayed with oil have friction and wear resistance, and long-term use will not cause wear, which can extend the service life of silicone products.

With the increasing popularity of silicone products, people's aesthetic standards have risen sharply, and the demand for silicone products has also increased. While ensuring quality, it is also necessary to increase the aesthetic standards for silicone products. Therefore, a new technology - drip glue technology - has emerged. The benefits of drip glue technology for silicone products are not only to protect the surface of the product from wear, but also to pursue high-quality and exquisite appearance of silicone products. It is not difficult to make a lifeless silicone product into a three-dimensional, concave convex appearance effect, and a few points need to be noted. 1. In the process of making dropper silicone products, it is necessary to ensure the cleanliness of all utensils during the dropper process to avoid impurities, ripples, and other defects on the surface after the glue solidifies. 2. In the process of making silicone products using the dropper process, the glue ratio must be accurately weighed, and the glue must be stirred evenly, otherwise it will cause incomplete dropper curing and prolonged curing. 3. The humidity of the glue dispensing working environment should be controlled at 68%. It is not recommended to perform glue dispensing work on rainy days because when the humidity in the air is too high, the mist in the air will directly cause the surface of the glue to oxidize. If the production task is tight, it is recommended to use an air dehumidifier. When producing silicone products with droppings, the silicone products are concentrated in the drying area and the temperature is controlled between 28 ° -40 ° C to ensure that the droppings are of good quality and reduce the defect rate.

In the field of polymer materials, silicone and rubber are well-known materials, but the question of whether silicone belongs to a type of rubber often sparks discussion. To accurately answer this question, it is necessary to analyze from multiple dimensions such as the chemical structure, performance characteristics, and processing methods of the material. From the essence and definition of materials, silicone belongs to a special category of rubber, scientifically known as "silicone rubber". Rubber usually refers to a highly elastic polymer material with reversible deformation, which is elastic at room temperature and can produce significant deformation under very small external forces. After removing the external forces, it can restore its original state. Silicone possesses typical characteristics of these rubbers, but its molecular structure and properties differ from traditional rubbers. Ordinary rubber is mainly composed of elements such as carbon and hydrogen, while the main component of silicone is polysiloxane, with silicon oxygen bonds as the main chain structure. This makes silicone more excellent in high temperature resistance, low temperature resistance, weather resistance, electrical insulation, and other aspects.In terms of high temperature resistance, ordinary rubber is prone to aging, deformation, and even decomposition in high-temperature environments. Silicone can be used for a long time in high temperature environments above 200 ℃, and some specially formulated silicone can withstand higher temperatures. This characteristic makes it play an important role in high-temperature working scenarios such as aerospace and automotive engines. In terms of low temperature resistance, silicone can still maintain good elasticity and flexibility even under extreme cold conditions of -60 ℃. In contrast, many ordinary rubbers become hard, brittle, and lose their elasticity at low temperatures. In addition, silicone has excellent weather resistance, with minimal performance changes and a long service life when exposed to natural environments such as ultraviolet radiation, ozone, and wind and rain for a long time. It has significant advantages in outdoor sealing components, building materials, and other fields. From this, it can be seen that although silicone has similarities with rubber in terms of elasticity, it does not fully belong to the traditional category of rubber based on comprehensive factors such as chemical structure, performance characteristics, and processing methods.

The application range of silicone plugs is extremely wide. In the field of daily life, it is the "capable assistant" of kitchen supplies. Various wide mouthed bottles, storage tanks, and hot water kettles are often equipped with silicone stoppers, which utilize their excellent sealing performance to isolate air and moisture, extend the shelf life of food, and prevent seasoning from getting damp and clumping. In the beauty and skin care industry, containers such as face cream bottles and essence bottles can not be sealed without silicone plugs, which can effectively prevent the volatilization and oxidation of the contents and maintain the stability of product quality. In the industrial field, silicone plugs also perform well. During the manufacturing process of electronic devices, silicone plugs are used to protect the sockets of circuit boards and interfaces of instruments from dust and water, in order to prevent equipment failure caused by external impurities; In automobile manufacturing, silicone plugs are used to seal oil and gas interfaces, ensuring stable operation of automotive systems and improving safety and durability.The reason why silicone plugs can establish themselves in many fields is closely related to their significant advantages. From the perspective of material characteristics, silicone has good high and low temperature resistance, and can maintain stability in the temperature range of -60 ℃ to 200 ℃. Whether it is a hot water kettle or a low-temperature refrigerated container, silicone plugs are capable of sealing work. At the same time, silicone material is non-toxic, odorless, environmentally friendly, and meets food grade and medical grade standards, which is also the key to its wide application in kitchen, medical and other fields. In addition, silicone plugs have excellent elasticity and can tightly fit the container mouth, forming an effective sealing effect. They also have excellent aging resistance and are not easily deformed or cracked after long-term use.

The silicone button spray process is the core technology for improving product texture, touch, and lifespan, with significant differences between different processes. Based on industry demand, we will provide a detailed breakdown of the core characteristics, advantages and disadvantages, and applicable scope of mainstream processes to assist in precise selection.The silicone button spray process can be divided into three directions based on function: color expression, tactile enhancement, and high-end protection. It can be used alone or in combination to achieve dual improvement in appearance and performance.Firstly, there are color expression techniques, with the core of endowing buttons with rich colors to solve the problem of single color on silicone substrates, mainly including spray oil and two-color/multi-color spray oil.Spray oil is a basic and widely used process, which achieves customized colors by spraying colored oil-based ink on the surface of silicone gel, and can achieve luminous effects. Its color is full, can be freely adjusted, has low cost, and simple process; But it has poor wear resistance, is prone to color and oil loss, and has average adhesion. Suitable for civilian products such as TV remote controls, air conditioning buttons, etc. that require low wear resistance and focus on cost.Dual color/multi-color spray is an advanced process for spraying colored oil, which uses masking technology to spray different colors multiple times without the need for laser engraving to present a sense of layering. Its appearance is high-end and its appearance is outstanding, but the process is complex, the yield is low, the cost is high, and the wear resistance is not as good as high-end protective processes. Suitable for high-end products such as game controllers and smartwatches that emphasize appearance.Secondly, there are techniques for improving the tactile sensation, with the core being to optimize button touch and create a skin friendly and anti slip experience, mainly including spraying tactile oil and rubber oil.Spray feel oil, also known as matte oil spray, forms a micro matte coating by spraying matte ink, presenting a matte effect, not sticking to fingerprints, with a delicate and smooth touch, and good anti slip properties. It has a good hand feel, high cost-effectiveness, and can be reworked, but long-term friction can easily wear and expose the bottom. Suitable for high-end rice cookers, Bluetooth earphones, and other experiential home appliances and digital products.Spraying rubber oil is a high-end tactile process, using high elasticity rubber coating to present a deep matte texture, with a soft and elastic touch and optimal anti slip performance. It has excellent tactile sensation and enhances the high-end feel of the product, but it is costly, difficult to process, and prone to peeling and detachment due to inadequate pre-treatment, which is greatly affected by the environment. Suitable for high-end products such as car air conditioning knobs and high-end game controllers.Finally, there is the high-end protective technology, which focuses on solving the pain point of silicone buttons not being wear-resistant. The mainstream technology is spraying PU oil.Spraying PU oil, also known as polyurethane spraying, forms a high-strength protective coating, mostly transparent or semi transparent matte, with a dry and solid touch. It has super strong wear resistance, good chemical resistance, and strong adhesion, and requires corona/plasma treatment; But the cost is high, cannot be reworked, and has extremely high requirements for the production environment. Suitable for products with high durability requirements such as car keys and industrial machinery keyboards.In actual production, different processes can be combined to meet the requirements of color, touch, and wear resistance. Process selection should be based on product positioning, usage scenarios, and cost budgets to accurately match production needs.
