Prototite is a specialised casting alloy based on electrolytic zinc. It has good mechanical properties, excellent machinability and exceptional reproduction of fine detail. Casting does not require a foundry.
APPLICATIONS
Plastic moulds for blow-molding, vacuum forming and most injection and compression moulding.
FEATURES
- Hardness can equal mild steel.
- Machinability better than aluminium.
- Reproduction of details allows for mould cavities, even finely textured surfaces such as leather cloth finishes to be used directly as cast.
- A variety of techniques both pattern making and casting are suitable, including casting in sand, ultra fine facing sand or against plaster ceramic or metal masters.
- Remeltable and recastable several times provided that precautions are taken to prevent contamination.
- Prototite may be affected by some chemical solutions. Simple tests are recommended in case of doubt.
- Note: Pattern allowance for shrinkage approx. 0.1 mm/cm (⅛"/ft)
