Hand Lay–Up:
One technique of fiberglassing is called Hand Lay-Up. A Laminator hand mixes resin and catalyst, pieces of pre cut fiberglass are wet out on a table and placed into a mold. The Laminator uses rollers to ensure there will be no air in the part.
Chop:
Chop is a laminating procedure that uses a “chop
gun”. This gun automatically mixes resin and catalyst
while simultaneously chopping strands of glass, which
spray out of the guns nozzle. The chopper operator evenly
coats the mold with the glass and resin mixture. Then
the laminator uses rollers to roll out all air.
RTM:
Resin
Transfer Molding or RTM is the procedure that pulls the
resin through the mold. The Laminator, in this procedure
places pre-cut glass into the bottom of the two part mold.
The top part of the mold is lowered into place and the
vacuum hoses are connected and turned on. The results
of using the RTM method both sides of the part have a
smooth finish.
Computer Numerical Control:
Custom Fiberglass Molding, Inc. operates three CNC routers
that are programmed to trim parts with speed and accuracy.
