ILLIG was prompted  to further develop the pre-heating technology due to the specific demands made on thermoforming of thermoplastic materials, especially PP. Initially developed for processing thicker materials it soon became obvious that higher outputs and improved product quality were achieved for thin materials as well when employing a roll pre-heater.
In VHW roll pre-heating systems heat transmission is gentle due to maximum material wrapping angles around the heating rolls. The heating rolls are located in a fully insulated cabinet. For this reason energy consumption is kept on a low level and the material does not cool down in contact-free space. Uniform material heating with minimum start-up waste can only be achieved with contact heating. Designed as independent unit a pre-heater can be easily integrated into existing thermoforming lines.
