Casting Service

Since 1972 Regal have offered continuous service to manufacturing jewellers in New Zealand, and are the longest serving contract caster in the country.

Casting alloys

Our in-house metallurgists are constantly working on perfecting our alloys to assist in all aspects of jewellery manufacture. Our specialised range of alloys has been developed over many years of working closely with our customers.

Cast finishing

All castings are bead blasted to ensure you receive the highest quality finish. 

Moulds

We have developed our own specialized mould cutting techniques and offer an urgent service when required at no extra cost. We have several moulding materials available to allow for the most suitable option and the best result from your patterns.

Alloy Density Conversion

Alternately, use this density table to help you calculate the weight of your castings from the weight of a wax, or to estimate the weight of a finished piece from the weight in a different alloy.

To convert from one alloy to another divide weight by the known alloy density and then multiply by wanted alloy density.

e.g: A ring weighing 3.0 grams is made of Sterling, and you want to know the weight of the same ring cast in 18ct Yellow.

3.0 ÷ 10.4 x 15.5

= 4.5 grams in 18ct Yellow
