The lower mould is machined with a fixed cavity thickness which can be reduced by fitting optional shim-plates (cavity range of 0.5mm to 15mm)
The upper mould consists of 19mm heat-toughened plate glass in a supporting steel framework. This allows full observation of the injection process
The mould is clamped using vacuum only (VRTM) and is limited to use at low pressures up to 0.5 bar positive
Injection is via a peripheral injection gate with a central vent.
The lower mould includes oil/water heating channels or integral electrical heating with the appropriate insulation
The upper mould is hinged and supported on gas-struts for ease of operation
Air ejector system is included with standard specification
Heating Options
Heating:
Oil/water heating is recommended for heating up to 150°c (see option 08)
Electrical heating is recommended for heating up to 180°c. Two options are available for electrical heater control (see options 09 &10)
Note: Protective insulation will be required for moulds operating above 50°c, option 11 will need to be specified if going above this temperature.
