To control the quality of silicone rubber products, you must pay attention to several factors:
First, the quality of silicone raw materials will lead to difficult to remove the silicone products, poor quality silicone raw material, its lack of toughness, tear strength is also clearly inadequate, in the process of demolition is certainly difficult to remove the edge.
Second, the product molding molding process is relatively thick, then the raw edge is actually quite thick, and the increase in the thickness will certainly lead to the difficulty of demolition.
Third, vulcanization environmental factors, vulcanization temperature should be appropriate, too high and low problems will lead to difficult removal, while vulcanization time also requires a good control, curing time is too long will lead to products become brittle, curing time is too short It will lead to no effect on the vulcanization, so the vulcanization must be controlled.
Fourth, the mold molding problems, if the mold from the demolition of the design is not reasonable, the molding mold is used too long, the molding mold wear is serious, the molding mold quality, but these conditions will lead to the production of molding is difficult to remove the edge.
