Silicone Mold Vacuum Casting
Silicone mold vacuum casting process:

1.Silicone mold building. With the finished prototype, casting master to build the silicone mold;
2.Mold curing. To cure the mold in oven under 40 centigrade degree for about 12 hours;
3.Mold splitting. Take the mold out, prune it and split the mold along the parting line, take the prototype out of the mold;
4.Mold preheating. Put the mold into the oven and preheat it under 70 centigrade degree;
5.Vacuum casting. After preheating, put the mold into vacuum casting machine, pour the resin into the mold through the sprue after 5-10min vacuuming;
