Ceramic mold silicone operation method

Ceramic mold silicone operation method

1, silicone and curing agent. 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 ( Note: silicone and curing grout must stir well, if there is no uniform mixing, the mould will be a piece of has solidified, a no cure, silica gel can appear uneven drying curing condition will affect the service life of the die and the silicone mold number, and even cause mold scrapped.

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 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.

3, besmear to brush, or operation process: the time bubble of silica gel, by brushing or perfusion. Pour in the product above ( Note: to replicate before pouring silicone products or model release grout must be hit or isolation agent) 。 Then put the silica gel coating on product, besmear brushs must be uniform, a layer of gauze in firbre cloth paste 30 minutes to increase the strength of the silicone and tension. And coating a layer of silica gel, then a layer of gauze in firbre cloth paste, so after two is ok. Only by doing so, out of the silicone mold service life and mould number relative to improve a lot, can save cost and improve efficiency.

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.

5, irrigation or infusion modes of operation: irrigation mode or perfusion model, 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) 。
