RF Pultrusion Preheaters - Single Electrode
RF PULTRUSION PREHEATERS - SINGLE ELECTRODE
Pultrusion Preheater 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. A cured part exits the die, ready to be cut to length.
For parts with a thicker cross section, companies have found it advantageous to add dielectric heating equipment such as the Thermex RF Pultrusion Preheater to their Pultrusion line. The RF Pultrusion Preheater is used to heat the inside of the part before it enters the heated die. This increases the line speed. Additionally, manufacturers can produce a better-quality product; protected from the risk of a part stress-cracking.
Thermex Pultrusion Preheaters are available in both single-electrode and multi-electrode models. The single-electrode model offers similar output power, voltage and input power KVA as the multi-electrode, but with a smaller spatial footprint.
Proudly made in the U.S.A.

Terminology
Temperature Distribution
This prime variable determines how to melt or shape the microstructure of a finished product part’s outcome. Using specialized RF equipment facilitates control over temperature distribution.
Heated Die
This RF heating tool is a crucial part in the manufacturing process. Thermex-Thermatron equipment applies high frequency energy. Through this energy, plastic material melts. There is no RF heating or sealing process without polarized molecules, set between a pair of heated dies. This activates an electric field between the electrodes.
Reinforcing Fibers
These materials offer the support of high strength as well as stiffness. This helps manufacturers deliver exceptional production through RF technology. Using reinforcing fibers fortifies thermosets along with thermoplastics. Anything from glass to aramid, graphite, and carbon are frequently used as synthetic fibers.
Powder Resin
Thermoplastic powder resins are cured in the RF heating process. From epoxy to polyester and vinyl ester, these powder resins help coat industrial raw materials.
