Variotherm injection moulding

Variotherm injection moulding is based on a graduate tempering method of the mould during a defined cycle time. Advantages for processes, moulded parts surface, stability and profitability are results of Variotherm processing. The already tempered mould surface is heated also by the hot plastic mass during the injection process. After filling of the cavity the mould is cooled till the moulded part has the necessary deforming temperature.  A higher surface quality, a longer pressure impact in subsectors far from the sprue, less residual stress and warpage in the moulded part, optimised cycle times as well as less injection pressure and clamping force are advantages offered by this method. We have the necessary know-how to support you also when it comes to work with this special process.
