The pultrusion molding process is to heat the continuous roving, felt, belt or cloth and other reinforcing materials soaked in glue, under the action of traction force, through the mold heating, pultrusion, molding, and curing, and continuously produce FRP profiles of unlimited length.
The pultrusion process is a special process in the FRP forming process, which is suitable for the production of FRP profiles with various cross-sectional shapes, such as rods, tubes, solid profiles (I-shaped, grooved, square profiles) and hollow profiles.
Advantages:
1. The production process is continuous, the product quality is stable, and the repeatability is good;
2. The content of reinforcing materials can be adjusted according to requirements, and the product has high strength;
3. The longitudinal strength and transverse strength of the product can be adjusted to meet different usage requirements;
4. It can produce products with complex cross-sectional shapes to meet the requirements of special occasions;
5. The products have good integrity and the utilization rate of raw materials is high;
6. The investment cost of equipment is low.
