Preheating Ovens for Thermoforming


FILM PREHEATING OVENS for P.P. – P.E.T. and other materials.

Heating by hot air with temperatures up to 160°.

A set of idle cylinders, motorized silicon rubber pulling cylinder with corresponding contrast cylinder, fiber optic photocell for pulling cylinder control are mounted inside so as to feed the thermoforming machine.

Total length of inner oven film from 15 to 19 meters. It is also equipped with automatic material crimping system , so as to facilitate the material crimping, without manually providing to wrap the film on the cylinders to have inside it from 15 to 19 meters of film, this operation will be done automatically when the door is closed.
Complete supply of electric control panel for air recirculation fan, rubber cylinder inverter control and related photocell and air thermoregulation.

Main features
Uses and application

Range of ovens for treatments on metals, typically treatments on brass, steel, etc., with which various types of treatments such as stress relief, tempering, and stabilization can be carried out, with the aim of reducing internal and residual stresses that result from hot and cold working, hardening treatments, and machining, with temperatures ranging from about 150°C to 500°C depending on the materials. These ovens are used, for example, for stress relief treatments of brass components, with temperatures of 250-450°C, and for stress relief treatments after soldering.

Tempering is a heat treatment usually performed after hardening, with the aim of obtaining the desired hardness/tenacity ratio. These ovens are suitable for treatments for temperature ranges from 150°C to 450°C.

A widely used technique for assembly or disassembly operations of mechanical components and transmission organs, which involves using heat-generated thermal expansion to overcome the dimensional interference of two components and create an extremely strong mechanical coupling.
