High Performance Mould Materials
Overview
•
Mould weight is significantly reduced due to density being one third that of steel.
Moulds are easier to handle and exert less strain on processing machinery.
•
High metal removal weights are possible due to excellent machinability.
Moulds can typically be made in one third the time taken for steel.
•
Polishing is quick and easy. High standards of microstructural integrity mean high
quality mirror finishes can be obtained enabling Alumec
®
products to be used in
optically critical applications.
•
Thermal conductivity is typically four to five times that of steel. Simpler cooling
circuits may be designed or cycle times reduced. Temperature differences
throughout the mould are minimised so reducing moulded part distortion.
•
Easy surface to treat. Processes such as chemical nickel, hard chrome and hard
anodising can provide enhanced surface properties.
•
Easy to spark and wire erode. Metal removal rates are at least four times that of steel.
•
Easy to photo-etch, Response is even and uniform throughout enabling parts to
be easily matched.
