Rubber processing

Manufacturing tires and technical rubber goods require a precise temperature control to guarantee the product quality. Kelviplast provides temperature control for the following appliances:

  • Mixing machines
  • Extrusion plants
  • Calandering machines
  • Tread machines
  • Cooling sections
  • Profiling machines
  • and various processes in the production of technical rubber goods

Plastics processing

A crucial factor to maintaining product quality during processing plastics is the temperature control. Targeted heating and cooling provides the specific characteristics in products like plastic sheets, non-woven sheets, injection molding or PU-systems:

  • Roller temperature control, roller cooling and roller heating in the area:
    • thermoforming sheet lines
    • Chill roll systems
    • Stretch forming systems
    • Stretch conditioning
    • Nonwoven lines
  • Pelletizing equipment
  • Injection moulding

Chemical / Pharmaceutical industry

Chemical and pharmaceutical processes need a highly precise temperature controlling to operate exothermic and endothermic processes. The following examples have been installed successfully:

  • Temperature control of double-wall tanks (also for petrochemical industry)
  • Fusing of wax
  • Cold traps
  • Process cooling, process heating, ex-performance, with/without active refrigeration

Coating / Composites materials

The high demand of coating different materials like glass, paper, plastics sheets or composites materials requests a great reliability in regard to the temperature control. Kelviplast solutions can be found especially in the following applications:

  • (Vacuum) film coating
  • Paper coating
