The melting of thermoplastic materials requires temperatures of several hundred degrees Celsius. In many cases, thermal separation of the injection-moulding machine from the mould mounted in it is essential, if only for safety reasons.

Deformation and ultimately machine failures can result from the machine being exposed to high temperatures. An external insulation on the mould base prevents too much heat from being freely transferred to the injection-moulding machine.

The insulation also ensures a constant temperature inside the tool. The mould releases less energy into the environment while a homogeneous temperature balance develops within the tool. This leads to shortened heating process and fewer readjustments. Controlled and minimized total energy consumption is primarily responsible for improved energy efficiency of the tool.

In addition to the short-term and permanent temperature resistance, the pressure resistance of the insulation boards plays an important role, since the materials in use must withstand the enormous clamping forces of the machines. Knarr’s standard portfolio therefore includes the alternatives of 330 N/mm2 and 600 N/mm2. Prefabricated central bores and / or fixing holes are further options.
