BFG International uses a variety of methods to produce FRP parts. Our experienced engineers will select the best method for your project based on factors such as production volume, parts dimensions, budget, and other requirements.
Our extensive experience with press moulding enables us to produce innovative and cost effective parts for our OEM customers, including Volvo and Siemens.
The process is best suited for high strength parts with an excellent two-sided finish, and for high production quantities of more than 10,000 parts per year.
The resin and fibre reinforcements containing a temperature-activated catalyst are placed in matched metal moulds mounded in a hydraulic or mechanical moulding press. The mould halves are heated to temperatures ranging from 150 to 160 degrees Celsius and a pressure of approximately 1000 psi is applied. While the mould remains closed, the thermosetting material undergoes a chemical change (cure) that permanently hardens the shape in the mould cavity. Moulding closure times vary from about 30 seconds to several minutes, depending on part design and material formulation. When the mould opens, parts are ready for finishing operations such as de-flashing, painting, bonding, and installation of inserts for fasteners.
Resins: Thermosetting materials such as SMC (sheet moulding compound), BMC (bulk moulding compound)
- The process yields two excellent finished surfaces and outstanding part to part repeatability
- Trimming and finishing costs and time are minimal
- Unsuited to Complex Designs
- Low Cost Effectiveness
- susceptible to breakage when the finished item is removed from the equipment.
- Process Duration
- Lightly loaded structural panels, e.g. caravan bodies, truck fairings, bathtubs, shower trays, some small dinghies.
