2) Duplicate basic mold on the plaster cast with FRP materials;
3) Surface treatment of basic mold;
4) Duplicate a production mold based on the treated basic mold;







2. Pressing and forming
1) Turn on electric oven to preheat for 20-30 minutes. Wait till oven reaches specified temperature and then put the properly cut acrylic sheet into the oven to bake for 3-5 minutes;
