Hand Laying

It is the most widely used method for large surface FRP molding. Gelcoat is applied after the mold release agent is applied. After hardening of the gelcoat layer, fiberglass is applied with a polyester brush or wool roller. With hand lay-up, a molding method requiring low fixed capital investment, 25-35% glass fiber reinforced polyester products can be obtained. Since it is a labor-intensive production method, capacity depends on the number of labor and molds. An average of 2 products can be obtained from one mold.
