A Plates

Types A plates

  • Cavity Plate
  • Cavity Retainer
  • Front Cavity Plate

This plate retains the cavity in the mold. Its thickness is normally defined by the “depth” of the part. The runner system and gating are sometimes machined (half) in the surface of the plate. This surface is also the parting line surface and “shut off” (sealing) must be obtained or flash will occur.
