How to deal with deformation in silicone key production

How to deal with deformation in silicone key production

2020-10-09 11:30:51

Not to say that the silicone will not be permanently deformed, if the long-term stretch does not rebound when there will be deformation, what factors affect the deformation of the silicone key manufacturers. 1. Long-term immobility causes permanent deformation. Long-term use under high pressure conditions is easy to deform for products with hard materials under high pressure. 2. The influence of stretching rate is determined by the hardness and softness of the product. Generally, the winning rate of silicone rubber can reach 300 to 600 (relatively soft material). However, excessive stretching in the use process of silicone key manufacturers will directly lead to deformation and loss of stretching degree and permanent deformation. Therefore, it should not be excessively elongated in the use process, regardless of industrial products or raw materials. Live supplies or silicone jewelry are the same. 3. Influence of temperature occasions. In a humid place, when silicone liquid silicone is working, it will gradually deform when stretched during use under humid and high temperature conditions. However, with the adaptation and decrease of temperature, it will also lead to slight deformation of silicone key manufacturers. Therefore, whether it is accessories or sealing products used in the industrial application of silicone key manufacturers, in addition to human reasons, try not to let silicone key manufacturers stretch for a long time. The storage of silicone key manufacturers also requires certain skills. 1. The newly vulcanized raw materials are placed in a dry place. Due to the softness of the materials and the heat of mixing, a fan can be used to wake up and dry the raw materials. Generally, the raw materials are placed in high temperature, acid ozone and humid places, which will lead to the aging phenomenon of the rubber and accelerate the performance decline. The dispersion of rubber molecules in liquid silica gel leads to uneven molding color and dark stripes. Long-term storage leads to toughness and decreased expansion and elasticity. 2. The method of storing finished products can be to seal the packaging and sealed bags to prevent dust from entering, and to keep ventilated in a dry place to prevent the product from deteriorating due to oxidation resistance and deterioration. Do not place the product in a place with high temperature and light transmission outdoors, so that the product will be oxygen-free. When we properly maintain the silicone button manufacturer and place it in a dry place for ventilation, the silicone button manufacturer will not accelerate the aging speed and reduce the service life.

Do you know what silicone products are, do you use silicone products in your home, and do you know anything about silicone products. 1. The production process of silicone products: customer samples/drawings → design → customer confirmation → sample mold opening → proofing → proofing confirmation → confirmation of purchase contract → mass production mold opening → customized production according to contract requirements → QA → assembly and shipment. 2. The production process of silicone products: preparation of materials → mixing → molding → vulcanization → silk screen printing → spraying → trimming → packaging. 3. Silicone products have peculiar smell. The main reason for the odor is the odor emitted by the raw materials of silicone products after normal high temperature when the machine is hot pressed. Even silicone raw materials are no exception. Generally speaking, after cooling for three or four days, the smell will slowly disappear. Because silicone raw materials are non-toxic and tasteless environmental protection products, they will not cause harm to the human body. 4. The reason why the silk screen characters on the surface of silica gel products will fall off is that the surface of silica gel products is too dirty, which hinders the adsorption of silk screen ink and silica gel. The baking time or temperature after silk screen printing is insufficient, and the quality problem of silk screen ink itself occurs. 5. The advantages of silicone products, environmental protection, silicone itself is environmentally friendly and non-toxic, from raw materials into the factory to the finished product shipment process silicone rubber products factory does not produce any toxic and harmful substances, strong toughness, long service life, feel delicate, soft and comfortable smooth, cheap and versatile. In the process of production and manufacturing, sometimes there will be wrong size, either big or small, which can not meet the requirements of customers, which not only affects the efficiency but also affects the factory. So what is the reason for the difference between the size of silicone products and the original. First, mold temperature: when the molding temperature is too high, it will accelerate the vulcanization of the rubber compound of silicone products, resulting in the decrease of the fluidity of the rubber compound of silicone products in the molding mold, the size of the rubber product of silicone products is too small and the thickness is too thick. On the contrary, when the molding temperature is too low, the size of the silicone product after molding is too large and the thickness is too thin. Second, the pressure: caused by silicone key load bad, resulting in the size of the silicone products, molding pressure is too high, resulting in the size of the silicone products is too long, when the pressure is too low, resulting in the size of the silicone products is too small, the thickness is too thick. Third, the weight of molding compound: silicon discharges too much compound, causing bubbles in silicone products, the load of silicone keys is too high, the size of silicone products is too large, the weight of discharged compound is too light, and the size of silicone products is too small after molding.

Silicone finished products are famous for their superior elasticity and super high tear strength. Products made of silicone materials have long service life, comfortable hand feeling and flexible texture, which are incomparable to products made of other materials. Therefore, they are also widely used in many fields. In the production process of silicone products, it will be found that silicone finished products will appear brittle, which affects the production, and the brittle silicone finished product in the service life also can not meet the requirements, then, what are the elements of the occurrence of the brittle silicone finished product. First, the structure of the finished silicone product or the design of the mold causes the product to split briefly, and the product structure or the design of the mold is unreasonable, causing the finished silicone product to split briefly during molding. The solution is to modify the structure of the product or the mold to end the improvement, for example, slightly thicken the excessively thin local area, slightly round the right angle, etc. Second, the molding temperature is too high or the curing time is too long, resulting in brittle silicone products, the solution: lower the temperature to control the curing time. Third, the secondary sulfur ventilation is not good or the temperature is too high to form a silicone finished product brittle, silicone products factory solution: carefully adjust the secondary sulfur ventilation and control the temperature. Fourth, the material of silica gel itself and the elements of the glue itself constitute the primary elements of the brittleness of the finished silica gel product. Usually, the brittleness of the finished silica gel product is due to the poor quality of the glue itself and the tear strength cannot reach the request. In addition, many finished silica gel manufacturers now fill the glue with silica powder to reduce the cost in order to reduce the cost, which makes the glue whose original tear strength cannot meet the requirements more brittle. How to choose a good silicone sleeve. 1. Material: It is divided into pure silicone and ordinary silicone. Pure silicone has good toughness and will not turn white when stretched hard, while ordinary silicone rubber products are easy to break, and will turn white when pulled lightly, indicating that there is silicon powder with cheap value added in it, which is shoddy. 2, feel: good feel smooth, poor feel sticky. 3. Appearance: The good color is uniform, the poor surface is rough, the color is different, and even impurities can be observed. 4. Taste: Silicone has more or less peculiar smell, and poor silicone has a particularly strong and unpleasant taste. Secondly, the different molds, mold design is reasonable, fine degree, also different, which laid the silicone sleeve finished product quality, ease of use.

It is well known that the touch of silicone products are soft and comfortable and not easy to deform, with a transparent appearance, safe and non-toxic nature, etc. have prompted transparent silicone products to become the preferred modern life. The most common food-grade silicone products-transparent silicone nipples and pacifiers are eating tools that every newborn baby will use. Only when comfortable, safe and non-toxic silicone products are selected can the baby grow up healthily and happily, and the mother will feel more at ease. Silicone products, so our food-grade silicone products give you this sense of security. Transparent silicone nipple is made of pure natural silicone rubber, soft and elastic, toughness and tear resistance are excellent, not easy to be damaged due to use, easy to clean and high temperature resistance can use a variety of disinfection methods, the shape can be designed and controlled, to the closest to the touch of breast milk so that the baby can eat at ease. Now many people do not choose TPU transparent mobile phone shell and choose transparent silicone mobile phone shell reason is obvious, because the chemical molecules of silicone is very stable and not easy to deform, not easy to change the silicone products factory yellow. The thickness is moderate, good lubrication and toughness can play a very good protective role, and it is not easy to deform, environmentally friendly, non-toxic and durable, soft and delicate to the touch, so that the bow people can't put it down, the appearance of the silicone material after molding is first-class. Silicone safety performance:. 1. Silica gel is a kind of amorphous silica. The dust content in the workshop should be controlled not more than 10 mg/m3, and the exhaust should be strengthened. Wear a mask during operation. 2. Silica gel has a strong adsorption capacity, human skin rubber products can produce a drying effect, therefore, the operation should wear good work clothes, if silica gel into the eyes, need to use a lot of water to wash, and as soon as possible to find a doctor for treatment. 3. Blue silica gel contains a small amount of cobalt chloride, which has potential toxicity. It should avoid contact with food and inhalation. If poisoning occurs, a doctor should be treated immediately. 4. Silica gel in the use of the process due to the adsorption of water vapor or other organic substances in the medium, the adsorption capacity decreased, can be reused after regeneration. 14 years of silicone rubber professional custom manufacturing manufacturers, to provide you with the best products, silicone products factory in dongguan city custom tel: 0769-86652688-808,http://www.dgminz.com

Problems encountered in the production of silicone products

Problems encountered in the production of silicone products

Silicone products in the process of production and life, is already a very common product, the extensive use of silicone products to our production and life has brought a lot of convenience, silicone is a kind of environmental protection and non-toxic, has many excellent characteristics of a material, then, speaking of this, have you ever thought about what factors will affect the silicone products. One: composition parameters. The health and safety of exported silicone products is a problem that Europe and the United States attach great importance to. This year, it has been found many times that the pre-inspection and sampling inspection of exported silicone products are unqualified. The unqualified health index of exported silicone products requires us to improve the following three reasons and the quality control of raw materials is not strict. Some factories do not pay much attention to the raw materials used for kitchen tableware, silicone raw materials with low quality grade are used for the production of food tools without testing the raw materials, or unqualified colorants and auxiliaries are used for coloring in the production process, resulting in unqualified product hygiene. Two: the production process is not standardized. Due to the particularity of the safety requirements of silicone tableware, food silicone products have very strict requirements on the production process. After the product is formed, it takes enough time to remove volatile substances. In order to pursue efficiency, some factories have not reached enough processing time. Silicone silicone products factory because of its superior reliability, longevity and extreme temperature adaptability and stability and widely used, it will not be deformed, nor will it be damaged under extreme temperature exposure, different from the excellent characteristics of silica gel itself, widely used in life, to provide us with a lot of convenience, then, what are the common problems of silica gel. What are the specific production processes of silicone products. Preparation of raw materials (also called rubber refining, material preparation, etc.): including mixing of raw rubber, color matching, weight calculation of raw materials, etc. Vulcanization molding (also called hydraulic molding): the use of high pressure vulcanization equipment after high temperature vulcanization, rubber products to make silicone raw materials into solid molding. Pifeng (also called processing, removing burrs, etc.): the silicone sleeve products removed from the mold will be accompanied by some useless burrs and hole chips, which need to be removed. at present, in the industry, this process is completely completed by hand, and some factories also use punching machines to complete it. Why is it that there is no acid and alkali resistance and no aging resistance? In the process of making silicone molds, we suggest that customers should not add any silicone oil. If necessary, the amount of silicone oil added should not exceed 5% ~ 10% at most, because the amount of silicone oil added Too much will destroy the molecular weight of silica gel, so the mold will produce no acid and alkali resistance and no aging resistance. 14 years of silicone rubber professional custom manufacturing manufacturers, to provide you with the best products, silicone products factory in dongguan city custom phone: 0769-86652688-808,http://www.dgminz.com/
