The concave mold used by fiberglass

The advantages of the composite material, they can be molded into complex shapes is perhaps the most popular. When a shape that needs to be reproduced many times, the most effective way is to create a tool or mold, and manufacture in its inner portion. Molded parts emerge every perfect shape, almost no post-finishing work.

Molding or "seal" has been used for many years for shaping like body, home appliances and industrial lighting and other hardware products. Metal stamping die cumbersome and takes thousands of dollars to produce. Only large companies have the ability to build, operate, store, or even move these tools. Composite materials provide a cost-effective way, everyone can make such a mold, and for the production of plastic parts mass production of the same.

Concave mold has many advantages for medium to large volume production. Finishing time was significantly reduced, because every part of it has a smooth outer surface.
