In thermoplastic pultrusion, preheated continuous fiber bundles are pulled into an impregnation machine to completely saturate the fibers. The melt-impregnated reinforcement is then passed through the cooling mold, controlling the shape, size and finish of the final product. A mechanism is used to control the speed of the process and create a drag force on the product. Finally, the final product is cut using a pelletizing system. Glass fiber rod 0.472 is a pultruded fiberglass composite material, which is a thermosetting (Fiberglass cloth) elastic material made of continuous glass fiber roving and resin under the traction and molding of a pultrusion molding machine; the resin-rich layer on the surface makes it have good anti-corrosion properties. It has light weight, high(glass yarn) strength, good elasticity, stable and precise dimensions, and has excellent identity such as insulation, non-heat conductivity (Fiber glass), flame retardant, beautiful appearance and easy…
