  Formation Method
Main Formation Method
Laminating Structure
 
1. Hand Lay Up
After spreading wax on mold, the surface mat of thickness 0.3∼0.5㎜ is laminated with roller until you get thickness and strength you need. It's common formation method applied to complex or small to large forms. It's possible to change strength or thickness partly in laminating.


2. Spray Up
After spreading wax on mold, spray the compound of resin and fiberglass through a spray gun on the mold until it gets thickness.


3. Filament Winding
Wind roving absorbed in resin on rotating mandrel and then cure.


4. Lining
Clean surface for lining, and then spread primer. Spread resin added filler or laminate glass and resin.


5. S.M.C(Sheet Molding Compound)
Heat and press to form on a mold and a press. Cut glass mat as the form and put on the mold. Insert resin and then press.
The SMC method is applied to most large formation such as panel tanks, tubs or unit baths, purification tanks, parts of cars, cooling towers, and parabola antennas.


6. B.M.C(Bulk Molding Compound)
Heat and press dough with resin filler, glass fiber, catalyst etc.
The BMC method is used to small and complex products, parts of cars like head reflector and air intake, parts for copy machine or printers, and housing.


7. Cold Press
It is a method to form at normal temperature or up to 60℃ in a couple of molds. The molds are fixed at a press. Provide glass fiber and resin(usually use unsaturated polyester) together into opened molds by the press. Close and lock molds and form under pressure until cure available to unmold.
