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. |
