Gravity Die casting is the ideal process for manufacturing castings with requirement of high volume castings with consistent accuracy.
This process of casting uses hardened steel or cast iron permanent dies with impressions of the part, the runner and feeder systems already in set locations – avoiding the labour intensive method of making the moulds. Aluminium or Zinc is then poured into the cavity between the die sides and left to set, this can take anything from a few seconds to a few minutes – once set the die is opened, the casting is removed, inspected and left to chill.
The casting tolerances available with die casting are by far more than that of sand casting, with thinner wall sections and more complex shapes being achievable and the use of in-house produced shell cores to give high quality internal finishes as well as external.
Dies are always kept highly maintained at our premises, use of specialised coating and cleaning equipment means that the surface finish of the casting is to the highest possible standard and this also aides with the life expectancy of the tool.
