Introduction Of RTM Pultrusion Technology

RIM – pultrusion molding technology is a process method combined with the reaction injection molding (RIM) process. Compared with the ordinary pultrusion process, there are the following advantages:

The mixed and dipping process of the resin is carried out in the enclosed system, which can reduce the air bubbles and reduce the pollution of the environment.

Both the resin and the reinforcing material are preheating and then entering the impregnation, which can ensure the gel liquid has good wettability.

Can use a high degree of resin and fast curing, in order to improve production rate.

The reinforcing material in the state into the mold, easy to order.

The fiber and resin composition and stability, conducive to improving the quality of products.

The RIM pultrusion resin doesn’t have the problem of application time.

In the aerospace phase defense industry, pultruded profiles available for space station T type beam, aerospace plane cylindrical space rib, helicopter windshield control rod, warships and military camouflage bracket with a rod.
