Detail analysis for good FRP molding techniques.

1, the main mold making: making the main form many materials, generally require the materials easy to shape, easy to break, fiberglass chopped strand mat and there is good stability. Such as wood, plaster, wax and so on. We usually use wood. Depending on the product drawing or mold drawings, through the carpenter made wooden mold.

2, the main molding trim: master mold must be repaired before being turned mold production system. Trim include playing putty, change size more positive, reinforcement. During this process is mainly on wood mold surface and overall do basic treatment to ensure the size and form of wood mold coincide with the drawing.

3, the main mold surface treatment: this process has spray coat, gel coat curing, grinding, polishing, stripping wax. In the previous step, spray gel coat on Deal master mold (now usually choose easy sanding primer and high-gloss plastic), and then wait gel coat curing, after curing gel coat sanded gel coat surface. General from dozens of coarse sandpaper number has been hit fine sandpaper around a thousand numbers. After using sandpaper, polishing mold began, marked the final release product. Until this point, the main mode of production is over. Continued master mold can be used to make the production mold.

During this process will use many materials and industrial equipment. Timber and relative woodworking appliance is need. Moreover, putty (also known as putty), sandpaper, sandpaper from coarse to fine sandpaper tens number more than a thousand numbers, gel coat, mold cleaning agent, sealing agent, polishing paste, stripping wax. Moreover, you should use some small tools and instruments, such as sanders, polishing wheels, gelcoat spray gun, pump (or other gas source).
