Dynamic Mold Heating (DMH)

Dynamic Mold Temperature Control (Variotherm) - Powered by Heat

Product information

DMH (Dynamic Mold Heating) is a variothermal temperature-control process. The mold wall is intensely heated before injection and rapidly cooled again after filling. Depending on the requirement, one or both mold halves can be temperature-controlled. This process enables the production of parts with high-quality surfaces and improved properties in a single-shot process.

Elimination of typical injection molding defects
Creation of new, sophisticated surface designs
Savings in material during cycle time

Customized heating processes

A wide variety of heating processes are used in the DMH process, with the cooling phase usually being achieved using water.
