Tools for 3rd Generation Thermoformers feature longer service lives and improved part quality. A major development element is the symmetrical arrangement of all media. This is important for uniform part quality in all cavities. The use of new materials with improved heat conductivity results in higher cycle speeds. Maintaining operating conditions on a constant level in the machine means in longer service lives of tools as well as reduced maintenance costs.

This increase in productivity is supported by a an optimized new tool cooling system. Up to four cooling circuits are now available in the forming tool. They can be individually controlled and separately supply upper tool part, downholders now directly cooled, lower tool part and ejectors. The tools are equipped with cooling channels close to the cavities' contours with cross sections dimensioned accordingly to ensure that the heat is dissipated form the cavities as quickly as possible during high cycle speeds. Lowering the cooling agent's temperature is not required, quite the contrary. When in the past a cooling water temperature of 12 °C was required, tools of 3rd Generation RDM-K automatic pressure forming machines can now be cooled with water of 16 °C to 18 °C. A further major benefit of the increased temperature of the cooling water: There is less risk of formation of condensation water on the tool with increasing atmospheric humidity.
