Overview

Infrared lamps are placed crossed under the tooling plate and in the lid. Tooling plate in a square form with dimensions 320x320mm can be produced of any suitable material also with custom openings for fixtures inside it. Design enables loading of tooling plate inside the chamber together with the parts on it - suitable for serial production.

Process cooling by means of nitrogen flow that blows from the chamber bottom against the tooling plate.
