Generally speaking, the better the vulcanization effect is, the better the silicone products will be molded, but the temperature should be controlled. Too high will affect the quality of the products, and too low will affect the efficiency, so how to solve this problem? What is the effect of vulcanization on the molding of silicone products?
Vulcanization temperature is too high can easily lead to a product lack of glue, small size, thick thickness, deformation, numbness, brittle, easy to break, challenging to remove the edge of the bad, for silicone keys, but also very easy to cause the load is high bad. Another more exciting phenomenon when the vulcanization temperature is too high is also elementary to appear package wind.
The vulcanization reaction of silicone products takes the vulcanization temperature as a prerequisite, and the temperature directly affects the vulcanization speed and quality of the products. The lower the temperature, the slower the reaction speed and the lower the production efficiency. The type of silicone products and the vulcanization system determine the level of vulcanization temperature.
The problems when the vulcanization temperature is too low are the opposite of those when the vulcanization temperature is too high and can easily lead to small size, thin thickness, incomplete vulcanization, softness, etc. For silicone keys, it is easy to cause low load and black particles to fall off. However, some points are similar to the high vulcanization temperature, which is that it is difficult to remove the edge, package wind, and other problems.
When the temperature is low, the vulcanization effect is better. Still, it will affect the output of the product because the lower the temperature, the slower the reaction speed and the lower the production efficiency. On the contrary, high temperatures will improve production efficiency. At the same time, too high a temperature will lead to coking, brittleness, edge removal, and other problems with silicone products, affecting silicone products’ physical and mechanical properties. Therefore, companies fix the temperature and vulcanization time in the production process. Besides focusing on product output, companies also focus on product quality. Before putting new molds into production, they try to determine the most reasonable vulcanization temperature to improve production efficiency and quality.
The vulcanization temperature of silicone products should be set at a reasonable range. Too high or too low will affect the quality of silicone products when molding. Both high and low temperatures will affect the quality of silicone products when they are developed, so they must be strictly controlled during production. The IPQC of a silicone product factory should also be equipped with a meter. IPQC is also better equipped with a table to measure the mold temperature of each machine on time. Any abnormality should be improved immediately so that the defect caused by the vulcanization temperature can be reduced to a lower level.
