The spray molding process is to spray two kinds of polyester mixed with initiator and accelerator from both sides of the spray gun respectively, and at the same time spray the cut glass fiber roving from the center of the spray gun, so that it can be evenly mixed with resin and deposited on the mold. When it is deposited to a certain thickness, it is compacted with a roller, so that the fiber is soaked in resin, bubbles are eliminated and the product is solidified.
Injection molding equipment injection molding machines are divided into two types: pressure tank type and pump supply type.
