Custom Cast Technology

The production of custom cast parts or nylon castings offers many advantages over conventional parts production technologies:

  • Capability to manufacture small or medium quantity production series
  • Capability to manufacture large parts
  • Elimination or reduction of machining operations
  • Improved product performance
  • Scrap reduction 

Compared to machining stock shapes

  • Special formulations possible
  • Material savings up to 40% possible
  • Costly machining time is avoided

Compared to injection moulding

  • Heavier products (max. 800 kgs/piece)
  • Lower tool investments
  • Variations in wall thickness and heavy cross-sections possible

    Atmospheric Pressure Casting (APC)

    APC is used to make parts without externally applied pressure. The process is suitable for low-to-medium volume runs or even parts that may have intricate design details. APC cast nylon used for structural parts allows larger cross sections and minimizes flow-induced stress. Compared to injection moulding, this results in improved dimensional stability during use, with parts less likely to distort or change shape. Cast weight up to 800 kgs is possible.

    Low Pressure Casting (LPC)

    LPC allows the production of big parts with thinner sections and a more complicated shape, in addition to parts similar to those made by APC. Economical production runs are 100-300 pieces.

    Reaction Injection Moulding (RIM)

    RIM is a low pressure casting technology where specific additives are mixed with the base material. It shows very specific properties after "injection" in the mould and the polymerisation of the material. RIM casting is a perfect production technology for a wide range of products with different shapes and qualities.

    Nylons can absorb up to 7% (by weight) water under high humidity or submerged in water. This can result in dimensional changes up to 2% and a corresponding reduction of physical properties. Proper design techniques can frequently compensate for this factor.
