In the production process of silica gel products, edge removal is a very important process, in fact, the burr cut repair neat, but sometimes due to some elements of the processing technology and raw materials themselves, resulting in molding is not easy to remove edge, harm to the conventional practical operation, so we must find the actual reason, then to solve. The following Kemet silica gel for you to analyze:
Silicone products are difficult to dismantle the reasons:
First, silicone rubber manufacturers introduce the curing temperature is too low or the curing time is too short. Silica gel products become brittle, silica gel products are not vulcanized when the softness is very strong, so it is not easy to make burr and product separation when removing the edge.
Two, the curing temperature is too high or the curing time is too long. Silica gel product molding once the temperature is too high or vulcanization time is too long, it will cause the product molding after numbness or brittle, whether blind or brittle, there is great harm to the side.
Three, forming thin thick too thick. Note: Just make it as thin as possible while making sure the specifications are up to standard. The plastic plastic problem, the quality of plastic plastic is very poor, there is not enough tear compressive strength, poor ductility, forming is very easy to lead to cracking.
Four, the mold self-disassembly design scheme is not scientific, or the production quality is not qualified, or the mold is damaged for too long. The design of the mold is not scientific, and the opening of the mold is not sharp will cause the product to be difficult to remove the edge after molding. In addition, mold damage in the production process, or sandblasting frequency too much will also lead to self-opening coarse ton will directly affect the self-opening characteristics of silica gel products after molding. Silicone rubber manufacturers introduce in detail the problem of silica gel product stripping is very key, it affects the quality and productivity of silica gel products factory products, so in the production process to carry out strict control of the mold, only so can ensure the quality of production and manufacturing.
