Machines using electrical power in the extrusion process, which is a production process of pushing or pressing materials through a die to create workpieces with a consistent cross-section according to the die shape, face heat loss problems at the machine’s heater surface. During operation, the surface temperature averages 180-240 degrees Celsius while the room temperature averages 30-34 degrees Celsius, resulting in energy waste and indirect production costs. Solving this problem with removable thermal insulation ZAVE® offers the following advantages:
