The pultrusion profileis a profile product produced by the pultrusion process. “Pultrusion” combines“Pulling” and“Extruding” to Pultrude and stretch raw materials. So how exactly is pultrusion profileproduced?

In the pultrusion profilestandard pultrusion molding process, glass fiber, resin, and auxiliary materials are three major factors. The glass fiber is first immersed in the resin as a reinforcing material, and then a separate preform system is used to condense and polymerize the resin through a heated fixed mold. The impregnation process can be accomplished by pulling the reinforcing material through the soaking bath fluid or by injecting the resin into the injection chamber connected to the mold.

Pultrusion profileis made from a variety of resins, including the more commonly used thermosetting resins polyurethane, polyester, vinyl, and epoxy. Its characteristics are corrosion resistance, UV resistance, impact resistance, and so on, and glass fiber is to provide a strong guarantee.

The pultrusion profile's features have driven the use of all types of profiles in recent years, especially in the automotive industry, where the need for this technology is particularly strong, in addition, the product technology can also be used in agriculture and chemical industry, for manufacturing of livestock facilities, chemical plant construction with corrosion-resistant glass fiber reinforced plastic floor.

Pultrusion in the construction industry can be used for profiles, bodies, PVC window reinforcement, etc. . In the aerospace field, used in the manufacture of structural parts of aircraft; in sports and tourism, used in the manufacture of equipment with high strength characteristics: skis, poles, golf course flagpoles, tents and hut structures; in electrical engineering, glass fiber rod used for insulator and supporting structure of signal block element, etc..
