FRP MACHINES MANUFACTURERS,FRP MACHINE LINE,FRP MACHINES UTILIZED IN INDUSTRIAL FABRICATION
There are several ways to fabricate FRP Products, the following explains some of the most common FRP Machines utilized in industrial fabrication.
Hand lay-up
A process where each layer of the laminate is individually fabricated one at a time on a contact mold. Allows precise control of the glass content and ensures that the glass is thoroughly wetted out with resin. This fabrication method is the most labor intensive.
Spray-up
Similar to hand lay-up but glass and resin is sprayed on to the mold. Less labor intensive than hand lay-up but poor control of laminate thickness and quality due to air bubbles.
Resin Transfer Molding
Process where a closed mold is filled with glass and then injected with resin under pressure. The system is allowed to cure and then the mold is opened to remove the part.
Puller Pultrusion
Pultrusion is a continuous process for the manufacture of products having a constant cross section, such as rod stock, structural shapes, beams, channels, pipe, tubing, fishing rods, and golf club shafts. Pultrusion produces profiles with extremely high fiber loading, thus pultruded products have high structural properties.
FILAMENT WINDING
Filament winding is perhaps the most succinct and clearly named of all the processes. It is traditionally used to produce cylindrical and spherical products, e.g., chemical and fuel storage tanks and pipe, pressure vessels and rocket motor cases. The advent of computer-controlled winding machines has expanded the shaping capability, making it useful for products such as airframes, helmets, driveshafts.
FILAMENT WINDING
SMC is a high strength glass reinforced thermoset moulding material which is normally compression moulded. It combines long glass fibre and unsaturated polyester/ phenolic/ Vinyl and Acrylic modified resins to produce a high strength moulding compound. These materials are usually formulated to meet performance requirements of the part to be moulded. CME manufactures these materials at our Bayswater plant in Victoria.
