Silica gel products factory talk about silicone edge
In the process of producing silicone products, silicone products edge is an important process.
But believe that a lot of people will face such problems, some silicone products, easily can give tear open come down to the edge, and some silicone products, will not easy to break, and always will be broken or residual burrs, silica gel products open boundary problems is very important, it relates to the silica gel products factory product quality and production efficiency.
So, if you have to wonder why there will be a difficult to dismantle edge cases?
Together with the silicone products manufacturer tear open boundary problem of hard to see why.
One, the quality problem of the rubber, molding thickness too thick some silicone products factory to reduce the cost of production using some cheap rubber used in the production of cheap rubber tear strength and toughness is poor, after molding, products are easy to fracture phenomena.
Additionally forming thickness too thick to dismantle side also to have certain influence.
Second, vulcanizing temperature too low or curing time is too short vulcanizing temperature too low or curing time is too short for the edge has a certain impact.
Flexibility when not completely vulcanized silicone rubber products is very strong, not easy to make when down side so burrs and product separation.
Three, vulcanizing temperature too high or curing time is too long when silicone products molding temperature is too high or curing time is too long, cause numbness or brittle after molding, products, made an impact on subsequent open side.
Four design mold, mold problems in mould is unreasonable, the mold production since the open mouth is not sharp.
And mould wear in the production process or amounts of sand from the open mouth coarser, affect the silicone rubber after molding, products since the performance.
To sum up, in the process of producing silicone products, have to be strict control to the mold, molding thickness don't too big as well as to the time molding curing temperature and time control, choose good quality rubber, don't covet price cheap and choose the bad rubber, cheap rubber tear strength and toughness is poor, will affect the forming performance of demoulding, cause the silicone products is difficult to open or tear open while fracture, etc.
