Vacuum casting or silicone molding technology uses the model which produces by CNC machining or 3D printing method, to make the silicone mold in vacuum. And uses PU material to fill out silicone
mold cavity in vacuum, to form the exact same model as the prototype.
Silicone Mold materials are: domestic silica gel, imported silica gel, silica gel, silica gel.
The filling materials used: domestic and imported PU, POM, ABS, PP, PC high temperature resistant ABS
