Shell Moulding

About us 1

Shell moulding

 

Shell molding is a single use shell mould casting process that uses a resin covered sand to form a mould. We produce an extremely accurate product with a high productivity rate. We can produce small to medium parts that require high precision using the shell moulding casting process.

 

The shell moulding process can be used for both ferrous and non-ferrous metals, although most popularly cast iron, as well as carbon steel, alloy steel, stainless steel, aluminium alloys, and copper alloys.

 

We also have a unique vacuum backed shell moulding casting process.

 

Some of the features of using shell moulding include: 

 

  • CT9 tolerance, with high dimensional accuracy, reduces machining
  • A good surface finish
  • Excellent reproduction of detail
  • Very strong cores

 

Using this process we can produce:

 

  • Cast iron tooling
  • Items to fit within a 600 x 400mm plate size

 

Conventional uses include:

 

  • Shells are cast on a track
  • Up to a maximum of 35kg (approximately)
  • Medium to high volume production

 

Vacuum backed shell moulding process – a unique to Newby Foundries.

 

  • Shells are embedded inside a sand filled flask under vacuum pressure
  • The increased pressure allows parts up to 100kg to be cast at a high tolerance
  • There are various advantages including minimal mould dilation and increased gas removal
  • Medium volume production
