Car dashboard by Vacumm casting process :


Before making silicone mold, need to do A original, can by CNC machining or 3 d printing production, starts to make silicone mold, silicone and curing agent. Mold silicone appearance is flowing liquid, A component is silica gel, team B is curing agent.


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.


Brush or operation process: a method of painting or perfusion of silica gel that has been pumped through a bubble.Pour on the product (note: the product or model to be copied before pouring the silicone must be removed or separated).Then apply the silica gel on the product, the coating must be even, and after 30 minutes, paste a layer of gauze fabric to increase the strength and tension of the silica gel.


External mold production: general methods and materials is to mold all round, with rubber plate or wood, used 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, stick, besmear again again repeated two or three layer, can complete the die mould.


Method of irrigation mode or perfusion mode of operation: filling mould or filling mould, is used to compare smooth or simple products, no save work line to save time, is you want to copy product or model, a vacuum of silica gel directly into the product above, after being dry silica gel forming, take out the product. (note: perfusion model generally adopts the hardness of soft silicone to do die, so demould easily, does not damage the inside of the silicone mold products.
