Variothermal Temperature Control: More Gloss, Less Weld Lines

Variothermal Temperature Control: More Gloss, Less Weld Lines

In the filling phase, a higher contact temperature is required in order to achieve high-gloss surfaces or perfectly replicated microstructures and nanostructures. This is economically contra-productive, however, since only a low mold temperature enhances the cooling of the molding. Variothermal process control helps achieve both goals.
