The big quality silicone keys is not broken, broken bad phenomenon in the daily application will have a certain probability, the reasons are many, silicone keypad defect occurs in miscellaneous pieces of silicone rubber on the majority, of course, there will be a rupture of silicone keys in the production is bad. In addition, also known as: silicone keypad, silicone keypad, silicone keypad, silicone keypad, silicone rubber keypads, silicone keys. There are six major reasons for the breakdown:
Fist, when the temperature is too high
Silicone rubber keypads in the molding temperature is too high will become brittle, after the mold release, it is easy to break down, only to reduce the molding temperature.
Second, silicone button curing is not complete
When the temperature is too low or the curing time is too short, it will cause the product to be close to the mold is not easy to mold release, it is easy to cause rupture, the appropriate increase in mold temperature or prolonged curing time can be solved.
Third, silicone button molding mold surface is too rough or accumulation of dirt
Rough surface or accumulation of dirt is not conducive to mold cavity mold release, and not easy to mold the mold is easy to rupture, the mold must be cleaned or plating treatment;
Fourth, when the operation technique is not
With many mold master without professional training or work is not careful, not strictly in accordance with the instructions demoulding, will lead to the rupture of silicone keys bad, the need for workers professional skills training or strict operation system.
Fifth, when the model is not good when the silicone button
Leading products in the process of lifting the mold rupture, at this time need to be on the surface of the silicone button mold spray mold release agent can continue to produce the right amount;
Sixth, the use of key silicone is too poor
Some factories blindly reduce the cost by the key raw materials silica poor, resulting in production of silicone keys quality is poor, the rubber is too poor, good toughness, memory rupture, solve this problem we need to replace the good silicone keypad.
