Pressure DieCasting

Alucast Ltd has a purpose built high pressure die casting facility which has the capability to manufacture castings up to 10 Kilogrammes in weight and has the ability to produce high production rates up to 200 castings per hour, using computer controlled die casting machines.

The high pressure process is used for the manufacture of high volume parts that require high dimensional accuracy and good surface finish with a minimum of machining. Castings are produced by injecting molten aluminium into a metal mould and is the most cost effective method of producing for high volume requirements.

This method of production allows for castings to be made with a thinner wall section than that of the Sand or Gravity process e.g 1.5 – 3mm. As a result of the very fine grain size produced high strength is obtainable in the as cast condition, high pressure die castings cannot be heat treated.
