C R Clarke 911 Thermoforming Centre C R Clarke 911, The C R Clarke Thermoforming Centre 911 performs several thermoforming functions on a number of thermoplastic materialsFunctionMaterialsWeldingPolypropylene, PVC, ABSVacuum formingPolystyrene, extruded acrylic, PVC, ABS, polycarbonate, polypropylene, polyethyleneDome blowingCast acrylic, PVCDip coatingNylon, polyethylene, polypropyleneInjection mouldingNylon, polyethylene, polystyreneExtrusionPolystyrenePress formingCast acrylic, ABS, PVC All of these processes require heat and pressure, which are provided by the centre's ceramic heater system except the welding torch which has its own heat source and vacuum pump. The heaters are used to provide ambient heat in the temperature controlled, fan circulated oven or to provide radiant heat for the vacuum forming facility. The vacuum pump provides appropriate air pressures to the different functions when they are selected by the process selector switch PSS on the main control panel.Each material has an optimum heating time depending on its form, heating characteristics and thickness and a digital set timer is incorporated on the main control panel to assist in achieving correct heating times.
