Mould sand blasting on the importance of the silica gel products factory products!
In manufacturing industry, a lot of friends all know that sand blasting process, especially for machining center using the relevant parts of steel industry products for lift head tail, sand blasting, of course, in the silicone products industry of die mould sand is a kind of common product of a kind of improved method, maybe there are some special products do not to come out such as sticky mold silicone products, a variety of reasons are searched or wind bubble and so on reasons, mould sand blasting process can be used to make improvement, make the impact of sand mould surface change to the improvement of mold surface, improve the mould expansionary, anti-fatigue performance.
Sand blasting process in the selection of materials of different hardness of different sand, common sand material has glass sand, quartz sand, emery, iron sand, sea sand, etc. , and general silicone rubber products manufacturers are in the middle of the sand blasting process using both emery sand and glass, because internal mold for dimensional accuracy requirements are not high precision, and mould are commonly after quenching heat treatment, so also can choose to use two kinds of mixed sand, sand blasting in mold process mainly to the coating and clean the inside of the mold some flowers, and the mold core in the middle of the mould some process after discharge sand and some not so will choose a different material to deal with.
Sandblasting the surface roughness depends on the sand of coarse-grained.
So for silicone products factory of mould surface treatment was more important, different requirements of general product surface with different thickness of sand, the main function is to some of the mold core is invisible to the naked eye of concave and convex particles by sand blasting process smooth, remove residual some burr and rust to make the surface smooth, in the production process of the mold will not lead to stick mold products because concave and convex groove etc. Phenomenon, also let the product surface more smooth.
