Vacuum forming machine heating equipment

One of the main processes in the vacuum forming process of thermoplastic sheets and films is sheet heating. The duration and quality of electrical heating depends on the structure of the heater, the thermal inertia of the temperature heat transfer after radiating the surface, the distance between the sheet and the heater, the radiant energy absorption coefficient, the properties of the heater surface, and the thermophysical properties of the material. Commonly used heaters are electric heaters, crystal radiators and infrared heaters.
