Overview

Infrared lamps placed under (or optionally, also above) the tooling plate heat it up. The tooling plate in a rectangle form with dimensions 260x210mm 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. The chamber itself is water cooled. External water chiller is required, if not ordered with mounting rack MR23CP.
