Pultrusion Ovens

Pultrusion ovens use one of the most cost-effective and fastest growing methods for production of composite materials. In this continuous process a fiber reinforcement material is pulled through a resin bath then through a set of preform plates to begin to shape the bundle. On parts with a thin cross section, the bundle is then pulled through a heated die to cure the resin. Exiting the die is a cured part ready to be cut to length.

For parts with a thick cross section, it is necessary to add a Thermex RF Pultrusion Preheater to the Pultrusion line. The RF Preheater is used to heat the inside of the part before it enters the heated die. This RF preheating increases the line speed and helps to produce a better quality product by reducing or eliminating stress-cracking of the part.
