Switching Unit Vario-5

Special challenges in injection moulding cannot be overcome with classical mould temperature control. The solution is a variothermal control: High temperature during injection, cold temperature in the cooling phase.
Together with two temperature control units, the Vario-5 forms a variothermal system according to the fluid-fluid technique. Alternatingly, it links either the hot or the cold unit to the same circuit. It is quite possible to use existing moulds if the temperature control channels are suitably arranged.
Vario-5 provides easy and quiet operation. It supports the user in determining the optimum settings.

Applications of variothermal control

  • Elimination of weld lines
  • Contour accuracy in the moulding of the finest structures
  • Optimal surface quality
  • Reduction of high injection pressures
  • Reduction of sink marks

Improved temperature control
