Definitions

  • the high pressure occuring on casting is taken up by the mould carrier and the abutment and the clamping means for the mould halves is relieved from casting pressure.
  • the resin is supplied to the mould under a pressure of 2 atrn. to 3 mm, with suitable cross section of the mould, the total pressure acting on the two cover plates may amount to approximately 2 tons.
