Industrial applications


Cast Heaters are used within polymer and rubber processing industries (extrusion). Furthermore they are suitable for screen-changers and filter systems, for extrusion tools, for foiling and blow moulding machinery, for profile welding machinery, for slot dies (e.g. plate and foil extruderds), for sealing-, packaging and dairy machinery, for accumulator grid moulding, as pre-heating station for forging tools, as special application (e.g. within the laboratory sector) or as chiller.
