Embossing plastics - Infrared Emitters Accelerate Production and Save Energy
Laminates or decors for furniture, windows or doors are often based on a plastic film which is embossed with a wood grain. The heart of an embossing line is the heating of the plastic web directly before the embossing calander. The surface of the foil should be soft enough for embossing, but the material must not suffer any heat damage. It pays off if the heat source can be precisely controlled. Replacing ceramic emitters with modern infrared emitters from Heraeus Noblelight brought the decisive improvement at Renolit in Great Britain. The tailor-made infrared system enables faster production speeds and helps to save energy.
