Discover Why Vacuum Bag Molded FRP Is Still "State Of The Art"
Compare The Process
For almost 50 years,
Fabri-Glass has specialized in vacuum bag compression molding of fiberglass reinforced plastics (FRP).
Vacuum bag molding, not
to be confused with vacuum formed thermoplastics, is one of the oldest and most versatile processes
used in the manufacture of molded glass reinforced plastic products. Often forgotten among newer and
more spectacular processes, bag molding continues to thrive at Fabri-Glass. We feel this process will
always be "state of the art" due to the ever increasing technological developments in
reinforcements and resins. When design dictates large size, light weight, complex configuration,
high strength, uniform thickness, and good surface finish, vacuum bag molding could be your answer.
Our process yields high strength, light weight parts that can arrive at your line ready for assembly. Weight and cost savings are even more pronounced when FRP is substituted for complex metal assemblies which require expensive tooling and extensive finishing operations.
Consider The Advantages
Vacuum bag molding offers the design engineer some significant advantages over other methods of FRP construction techniques, especially in low to mid range production runs.
- Comparatively minimal tooling costs are incurred
- Large and complex parts, impossible to press mold or spray up, can be easily fabricated
- Glass content determines strength, so reinforcements can be oriented in specific areas where stress distribution demands
- Design modifications can be made quickly and economically
- Design to production lead times are sharply reduced
Over the years, our clients have included such major manufacturers as AMF, Deere and Company, Diamond Reo Trucks, General Electric, Caterpillar, Navistar International, White Motor Company, Bandag, Inc., and Mitsubishi Motor Manufacturing. The wide variety of products we've manufactured includes:
- agricultural - tractor hoods, fuel tank shrouds, battery boxes, fan shrouds
- transportation - truck fenders, roofs, grill assemblies, air intake pipes
- off road equipment - road grader hoods, fenders, fan shrouds
- industrial machinery - gear and belt covers, motor shrouds, fan covers, machine covers, and enclosures
- waste water management - sewage treatment covers
- chemical processing - acid tanks, lab equipment
- recreational - golf cart, snowmobile, and all terrain vehicle bodies; boats, canoes
