Cut Off Saw
Pultrusion is a continuous process of pulling resins and reinforcing materials through a heated die, forming profiles of uniform cross section in a continuous length.
Pultrusion gets its name from the method by which the profiles are made. Raw materials are pulled by "the puller" which is located just before the final cut-off saw. The "puller" is made up of pulling pads that grip the product and drive the process.
The pultrusion process involves:
All the resins used in the pultrusion process have a catalyst or hardener added when the resin is mixed which is activated at about 93°C. Consequently, as the wet reinforcement passes through the heated die, the product changes from liquid to a solid profile with all the reinforcement laminated within.
The product is the pulled through the die by "the puller ". The final product is then cut to the desired length.
