1. Production process problems, which lead to air bubbles, dark lines or yellowing of transparent materials on the product during production, are common phenomena among silicone product manufacturers. These problems will lead to mold and vulcanization skills. In terms of mold, the temperature cannot be adjusted. The products made to meet the specified requirements are soft, partially unfamiliar, and even have color differences or yellowing. There are defects on the surface of the mold core or concave and convex openings that are invisible to the naked eye, causing the product to have air pockets and serious deformation. Therefore, during production Try to match the mold temperature, machine pressure, and vulcanization time to reduce product defects.

2. The problem of vulcanizing agents. Vulcanizing agents are divided into high-temperature vulcanizing agents and low-temperature vulcanizing agents. Both have different benefits. When high-temperature vulcanizing agents are used with raw materials, the demoulding of the product is faster, the product is molded out quickly and efficiently, and the product is resistant to corrosion. The yellowing effect is relatively good, and it is generally used in some products with relatively high anti-yellowing requirements, and the price of high-temperature vulcanizing agents is relatively expensive. However, ordinary vulcanizing agents are also commonly used as mixtures. They are mostly used for industrial accessories and sealed shock-absorbing products and are relatively cheap. Products with different hardnesses can be made with different vulcanizing agents. Therefore, a reasonable selection of vulcanizing agents is required during production. !

3. Raw material issues. Different raw materials of solid silicone have different toughness and tensile strength of the products. Some products must be made of high-tensile raw materials. Otherwise, products cannot be made from ordinary raw materials, and the products will be brittle or undercooked. etc., and some products must be made of food-grade silicone rubber raw materials, otherwise the product may have long-term odor problems. For example, some products in daily necessities that are in contact with the human body for a long time must use food-grade silicone. However, for silicone product manufacturers, these three points must be coordinated properly to make good products. Many problems are basically caused by the above three points.
