RM350 Gas and air consumption

In a gas injection moulding process, there can be a wide range of gas consumption and this depends on many factors including:

  • The gas pressure used to pack the moulding

  • The cycle time

  • The size of the gas channel

  • The length and bore of the tube connecting from the gas controller to the mould.

  • The amount of leaks between mould plates

  • The amount of leakage between the gas nozzle and the part being moulded.

  • Whether gas blows through an overspill (which is sometimes used to help carry away heat, but which we don’t recommend)

In general, our experience is that a gas assisted moulding channel consumes between 30 and 120 Nlpm of gas.
