MDF MOULDS AND PEWTER CASTING - SMALL SCALE CASTING - 1

V. Ryan 2008 - 2009

 

MDF is ideal for use as a mould when casting pewter. The melting point of pewter is low and does not burn or damage the MDF so that it can be reused time and time again.

 

The sides are generally manufactured from 9mm MDF with the mould being made from 4mm MDF. The shape of the mould can be cut using a coping saw or a fretsaw. The mould is usually quite small so care is needed when cutting and shaping. It can be smoothed with fine glass paper.

 

1. Cut a small piece of 4mm thick MDF.

2. Draw a simple shape on the MDF include the ‘sprue’. The sprue is the top part of the mould, into which the molten pewter is poured.

3. Cut away the shape using either a fretsaw or a coping saw. Smooth the rough edges with fine glass paper. The mould is now ready.
