We
have had great difficulty in obtaining a locally produced
polypropylene suitable for vacuum forming but will
continue to test until we obtain a material that works.
Our current moulds are half the cost of the imported
moulds but yield a semi gloss finish which has to
be hand polished if a high gloss finish is required.
If
you require a custom mould for your own resin jewellery
project you may wish to consider making your own silicone
mould which is a lot easier than you would imagine
and the design is uniquely yours.
