Your selection of a casting material
is dictated by what you want to make. If you are making
jewellery you would be looking at the resins. If you
are making novelty plaques for children to paint you
would need plaster and so on. We will concentrate
on the most popular casting materials.
Our most popular plaster Boral Casting Plaster is
used mainly for childrens plaster painting using our
plastic moulds. Silicone rubber molding material is
generally used with resins rather than plaster as
it is more expensive. We use it in preference to the
hardware store plaster of paris because of its finer
nature and the hardness of its surface which helps
prevent chipping and is a better painting surface.
For those who want a harder plaster or a special purpose
plaster we stock the American USG series of stone
plasters, Hydrostone, Hydrocal and Ultracal.
Opaque plastic-like resin:The
most versatile and easiest to use resin Casting
Material is Aldax CraftCast. It sets up in
3 minutes in a silicone mould and can be removed in
10 minutes. It is a hard white plastic product that
can be metal filled, coloured or painted for any number
of end products. It is a polyurethane resin.
We use it for toy train parts, antique car parts,
badges or decorative items of all descriptions. We
use a silicone rubber molding material called CraftSil
and recommend the two as the perfect combination.

Colourless hard plastic style resins:
Chief amongst these resin casting materials is Crystal
Cast resin an epoxy resin. It has little or no odour
and is a two part product that mixes easily one part
each of A and B We use this resin widely for resin
jewellery and similar products. It cannot be cast
large embedding moulds and for this we use a polyester
We would use Clear Cast polyester resin a lot more
if it did not have a highly objectionable odour and
a nasty catalyst MEPK. It is the lowest cost resin
and can be cast into moulds of any size for embedding.
It is water clear in colour. We recommend any of our
silicone rubber molding materials for resin casting.
We carry a range of low lead and leadless alloy metals
for the white metal casting of toy soldiers and train
parts. We also carry a leadless pewter for the badge
and jewellery makers. We also carry a range of silicone
rubber molding material suitable for high temperature.
CONCRETE AND CEMENT
We do not supply the concrete but the Latex Hobby
moulds and the PolyU polyurethane moulds for professional
users represent a major part of our business. We are
