In plastic industry there are different ways to produce plastic parts: Injection molding, Blow molding, Thermoforming, Extrusion, etc…
In all of these manufacturing alternatives, precise temperature control of tooling equipment (i.e. screw thread sections where plastic flow, mould, etc..), is strategic for the process productivity and the quality of the finished product. A key role is then fulfilled by water chillers and Temperature Control Units (TCU’s).
Great impact of HVAC units is also in terms of energy efficiency, as cooling typically consumes 11% to 16% of the energy used in a plastics processing plant.
According to the type of plastic, mould temperature (5-220 °C) and melt temperature ranges (150-400°C) vary a lot, calling for flexible HVAC units with fast response and adjustable set-ups.
