Compression Moulding

Compression moulding is a technique mainly for thermoset moulding in which the moulding compound is placed in the open mould cavity. Heat and pressure are applied until the material is cured. Compression moulding is often used for moulding of glass fibre reinforced plastic.

The technique is often used for molding of glass fiber reinforced parts and high pressure is often used. Wear resistance, strength and hardness are required from the mould material.

There are several advantages with compression moulding:

  • No waste of plastic material (no gate or runner system)
  • Minimum of internal stresses in the part
  • Process can be used for very heavy parts
  • Less expensive equipment

The grades recommended are ASSAB 8407 Supreme, Unimax, ASSAB XW-10, Vanadis 4 Extra SuperClean, stainless grades such as Stavax ESR, Mirrax ESR and Elmax SuperClean.
