METAL CASTING SOLUTIONS

EXPANDABLE MOLD CASTING

Expendable mold casting is a process that utilises reusable molds, for low volume or single use production to produce metal components. There are four main types of expandable mold casting techniques: gravity, slush, low-pressure, and vacuum.

The casting process involves pouring molten metal into a mould where it cools and solidifies. The mould is then opened, with the casting removed, and then the mould is reused. The mould is usually made from sand or plaster, which can withstand recurring heating and cooling primarily with low volume production.

There are several advantages as to why you should use expendable mold casting.

  • Very cost-effective process.
  • Low tooling cost, but small one-off production runs.
  • A wide variety of metals can be utilised.
  • Large parts can be cast.

There are a few disadvantages also to consider.

  • Less accuracy when compared to permanent mold castings.
  • Large tolerances required.
  • Process usually exceeds the calculated weight.
