The phenomenon of small products becoming brittle and soft is a relatively common phenomenon in the molding process of silicone products, and it is also a relatively distressing phenomenon. Many silicone product manufacturers become brittle and brittle in the production process, and they break when pinched, resulting in many bad problems in our production, seriously affecting our production efficiency, even if the products can barely pass QC sealing ring detection, the service life in the market can not meet the reasonable time requirements. 1. The first is the problem of production. The temperature is too high and the time is too long during molding and processing, which leads to brittle products, poor secondary vulcanization and ventilation for too long, material problems, and the main reasons for brittle or hard silicone products caused by materials are that the material itself is not good, resulting in substandard tear strength. 2. The unreasonable design of the mold and the unreasonable production structure of silicone products, the unreasonable structure of the liquid silicone product or the mold design of the product lead to fracturing of the mold product during production. It is suggested to improve the processing of the mold or the structure of the mold, and slightly thicken the thin place, slightly round the right angle, etc. 3. The most common reason is mainly caused by the operation method of personnel. Generally, silicone rubber product manufacturers will lock the vulcanization time in a time during the production process. Only when the mold time is well controlled can the product become brittle and soft. With the trend of the electronic product market, everyone is familiar with the current electronic protective cover and belongs to a very rising protective product. The selection of silicone material is not only a single choice of appearance, but also not inferior to other materials in quality, bringing more convenience to consumption. Everyone knows that a product has certain defects, so what factors are limited to the quality of silicone products. 1, silicone products tensile rebound strength: tensile strength is the root of rubber and plastic products, mainly refers to the silicone material in the tensile is what basic conditions, in different range of units to reach a certain standard, and silicone electronic protective sheath can get a certain degree of flexibility to achieve a good anti-fall shockproof effect. 2. Hardness and softness: Silicone rubber raw materials have certain different hardness and softness, which can be divided into 30-80 degrees. It can be applied to silica gel protective cover to a moderate extent. Under normal circumstances, the force and hardness and softness of silica gel have certain factors due to silica gel keys. If the hardness is too high, it is too brittle and does not rebound. If the hardness is too low, it is too brittle and easy to stick to dust.

Silica gel key leaching residue after acid leaching of cesium by Gulu silicic acid, due to leaching of iron and manganese and other elements, whiteness is improved, and due to leaching of various alkaline components, SiO2 content is also increased compared with silica, making it closer to the requirements of high silicon and low iron for SiO2 raw materials for sodium silicate, white carbon black and activated white carbon black. The total adverse phenomena in the processing of silicone products will bring great losses to the company, and the most special one is a kind of products with large sealing ring size and long processing time, which not only consumes a lot of raw materials, but also has a certain impact on time and energy. Therefore, the quality problems of silicone materials except molds, the phenomenon of dark marks often bothers us that we can't deliver the goods, so do you know what causes dark marks on silicone products. First of all, the reason for the dark marks or lines in silica gel products is not only caused by the vulcanization process, but also liquid silica gel has certain influence on rubber mixing, raw materials, mold structure and steel, etc. However, most of these products are included in white silica gel protective sleeve, flat back cover protective sleeve and overall area when the products are relatively large and the appearance is obvious and the color is relatively bright. In terms of color, the temperature of the roller and the proportion of color glue are not reasonably mixed during the mixing process. The most important thing is the control of the mixing time. The main reason for the appearance of material lines in the products of many silicone product manufacturers is that the rubber is not evenly mixed during mixing. Silica is the most important reinforcing agent for raw materials of silica gel products. In addition, it is also an indispensable raw material for rubber, plastic, paper making, coating, ink, paint making and other industries. Therefore, it cannot be ignored in quality. Many silica gel products commonly used by us must come from it. Therefore, there is a detailed analysis of material requirements and product performance. What is the processing of silica and how is it made. Most of the silica is supplied by foreign countries. Foreign countries not only produce large amounts of silica, but also silica gel products are developing into various inorganic fine chemical products. There are more than ten domestic manufacturers, and most of the silica produced are used for silica gel and rubber reinforcing agents. In recent years, with the improvement of people's living standards, the product structure of the rubber industry has undergone new changes. The amount of black rubber is decreasing day by day, replacing it with light colors and colors, the demand for transparent or translucent silicone rubber products is increasing day by day, so the market demand for silica is increasing rapidly.

In the electronic product industry, silicone film is also called silicone film talent. It is very practical to use silicone key materials and conductive silicone film for thermal conductive silicone film. Therefore, the selection of thermal conductive adhesive for heavy mechanical properties of many electronic products can reduce the thermal resistance of facial heat source and heat source of electronic products and maintain a certain temperature difference balance for products. Silicone products in the production process, the phenomenon of lack of glue and angle basically occurs frequently, and there are countless bad products caused by lack of materials. However, since this phenomenon belongs to the post-process processing problem, the sealing ring is not involved in the two links of mold and raw materials, so it can be said that the main revenue of this situation is often found to be caused by human factors, and the main reasons for prosecution can be divided into many types. 1. After the glue mixing is completed, there is no precise cutting process, the weight of raw materials is not enough, and it is difficult for skillful women to cook without rice. 2. There was no accurate mold test during the product proofing, the specifications and size of the raw materials and the placement method were not tested well, and the liquid silica gel caused the raw materials not to be filled in the mold cavity, resulting in glue shortage. 3. The raw materials are left for too long after mixing, resulting in a decrease in flow performance, failure of the vulcanizing agent, and failure to form normally. 4. There is no placement standard during the operation of material placement. Usually, this phenomenon causes the majority of poor material and glue shortage. The operator is not skilled in the product, resulting in inaccurate placement of raw materials and unable to flow to the corners of the mold core. Cushion gaskets are used in various fields, and many industries need to use silicone gaskets as auxiliary cushioning, cushion sealing and other functions. The reason why soft elastomer silicone sheets can be widely used is that they have good functions and use advantages, and various fields where gaskets are used can show different performance sides, such as the automotive electronics industry, construction industry and catering industry supplies and other silicone products. In the automobile industry, silicone gaskets mainly take the functions of sealing, shock absorption, buffering and environmental protection performance. Silicone products have been used in the automobile field in early years, such as mechanical sealing rings of manufacturers, silicone tube strips and automobile electronic miscellaneous parts, etc. The main functions occupied by silicone gaskets are still buffering, sealing and resistance.

Products such as jewelry protective covers basically go through the oil injection process in the market, and the problem of poor hand feeling will not occur after being used for a long time. It is difficult for us to observe the effect of oil injection with naked eyes, but there is still a difference between hand feeling and touch. The main characteristics of oil-injected products are smooth hand feeling, high surface finish, flat face, no sticky dust, improved wear resistance and strong adhesion. As we all know, a good product must first come from the outside to the inside. Whether it is a silicone product or a hardware and plastic product, all craft products are colored, so how to realize such colors needs to be matched, and how to make them complement each other, how to change the color of silicone products, and the color of good silicone products will also be very unique, there are many beautiful and bright colors in silicone products. How do these colors come true. Every silicone product needs to start from the modulation color, whether it is silicone kitchen utensils, silicone bib, silicone liquid silicone keys, silicone electronic accessories, silicone daily miscellaneous parts and other silicone products, or other technological products, all need this link, unless it requires the transparent color of silicone itself, but this is really rare, and the color of silicone itself is clear. Modulating color is a very professional problem, and it is also a job with a lot of technical content. In color science, mixing different colors to obtain another color is called hue change. Only by mastering the hue change first can the target color be modulated more quickly. There will be a big problem when there is a step difference in one process in the work. Silicone bracelet is no exception. There are many differences before and after oil injection. Oil injection is unknown to many friends. He mainly applies a layer of paint to the surface of the product in the industry to make the customer feel more comfortable. However, the difference in the process of a product on hand-sensitive oil is really very large. The effect of oil injection mainly lies in silk screen printing and pad printing in the rubber and plastic industry, oil injection effect, secondly, oil injection has a good effect on dust prevention and anti-sticking performance of silicone products. The reason why some friends of silicone products stick to dust for a long time is the problem of hand-felt oil. For silicone jewelry, there is a problem with the jewelry of many friends. After a period of time, the product is not as good as before, and the hand feeling is not as good as before, and it will feel a little sticky. In fact, this is caused by the silicone product manufacturer's failure to inject oil into the product, while this is generally not the case with high hardness products, silicone buttons think that some of our special silicone rubber or industrial products with high hardness requirements will not appear this phenomenon.

However, the appearance of many products on the packaging is the main reason to attract consumers to buy. Nowadays, many silicone product manufacturers have reduced the cost performance of their products because of an inconspicuous small package. Obviously, a relatively high-quality product has been destroyed in a package. Therefore, don't save costs, cheap and no good sealing ring goods, and blind selection of packaging bags is not acceptable. Whether the surface of the product is smooth or not is directly related to the mold. The quality of the mold directly affects the quality of the product. Then the silicone products must be prepared before production. How should the mold be handled to produce smooth and clean products. To produce high-quality silicone products, preparation work is very important. The preparation of liquid silicone molds and the preparation of raw materials need to be done as fully as possible. The first is to sandblast your mold. Sandblasting is a fine job. It is mainly to rinse the surface of the silicone product mold with fine sand under high pressure to make the mold surface more delicate and clean, and there will be no impurities in the production process, in addition to sandblasting the mold of silicone products, the steps of heating the mold, washing and touching, adding touch pads, etc. cannot be omitted. Silicone products now sales form is grim, in addition to the face of the production process problems, raw materials and mold problems and so on, every detail can determine whether the customer can pay for you, especially in the face of new customers when the details can always determine success or failure. From the appearance of the product to the appearance of the package, there are many details to be dealt with. In the appearance of the product, the matching of color silicone products and the saturation concentration of the color bring very important visual sense to consumers. Therefore, the concentration modulation of color modulation and color masterbatch is very important. Secondly, in terms of hand feeling, people will not feel rough and smooth. In the details of oil injection, it should be carefully checked whether it is comprehensive, whether the raw materials contain sundries or have expired in use, the mold closing line is also a very important point. The burr size of the silicone key offline often affects the main appearance of silicone rubber products and so on.
