mould operation method of silica gel
1, die general for industrial-grade silicone, is silica gel, condensation type mold silicone appearance is flowing liquid, A component is silica gel, team B is curing agent. Example: take 100 grams of silica gel, add 2 grams of curing agent silica mixed with curing agent in proportion to stir well ( Note: silicone and curing agent must stir well, if there is no uniform mixing, mould will be a piece of has solidified, a no cure, affect the performance of the silica gel.
2, vacuum exhaust bubble processing: after silicone and curing agent mix, vacuum exhaust bubble link, vacuumizing time shoulds not be too long, under normal circumstances, not more than ten minutes, vacuum time is too long, the silicone products curing immediately, the crosslinking, make the silicone piece by piece, cannot besmear to brush or infusions, thus wasting the silica gel, can only put silica gel in the trash, to take silica gel to do again. It is necessary to this link to open the mold. If there is no vacuum, cured silicone mold can contain bubbles, impact on the performance of silica gel, and beautiful shape. If there are no tickets in the next article I'll inform the exhaust vacuum machine run method.
3, brush mould process: in the first place in the mode of spray a layer of release agent, after dry, put to a bubble of silica gel, in besmear to brush the way. Pour in the product, above. And then put the silica gel coating on product, besmear brushs must be uniform, 15 minutes after a layer of gauze in firbre cloth paste is used to increase the strength of the silicone and tension. Then besmear to brush a layer of silica gel, can also be used in repeat the operation life of the die will be longer.
4, mode of production: the general methods and materials is to mold all round, with rubber plate or wood, used a plaster will die ark filled is ok, another way of using resin coating, coating a layer of a layer of glass fiber cloth paste resin, besmear again brush and then paste, repeated two or three layer, can complete the die mould. In general, gypsum mould suitable for small products, and easy to operate, resin material is suitable for large products.
5, irrigation or infusion modes of operation: filling mould or filling mould, is used to compare smooth or simple products, no save work line to save time, would you want to copy product or model, with plastic board or glass plate that will be a vacuum of silica gel directly into the products above, after being dry silica gel forming, take out the products, mold is molding the ( Note: perfusion model generally adopts the soft hardness of silica gel to do die, so that parting easier, not damage the inside of the silicone mold products) 。
Cupidove silicone products production mold silicone over the past 20 years, much progress, accumulate experience, hope I can help to you, need to learn more about the silicone mold can contact himself
