Answers:

  • What is lost wax casting?
    An original pattern is produced and a mould is made around it. We use this mould to make wax copies of the original design. These waxes are then encased in a special plaster-like substance. Once this plaster has set, the wax can be melted out, producing a cavity. The cavity is then filled with molten metal, which solidifies to create the casting.
  • Why is it called “lost wax” casting?
    The term lost wax refers to the fact that the wax is lost from the plaster mould, when it is melted out. Similarly, after pouring the molten bronze, the casting is found in the mould. [and hence, the term foundry].
  • Can you work from my pattern/drawing/photo?
    Yes. If you have a three-dimensional pattern to work from (a doorknob, for example) then we can make an exact replica. We also have a skilled team of modellers, who are frequently asked to work from paper designs, photos or even just a description. Our researchers can uncover designs from any era and our designers can produce designs that are complementary to any style.
  • Can you cast in steel?
  • We do not cast in steel. We do, however, produce wax patterns for a steel foundry. If your project requires any steel parts, then we can arrange for them to be made to your specification.
