Casting in Jewellery Manufacturing: How It Works

Casting is how most volume jewellery is made, and it is a chain where one weak step spoils everything.

The steps

Master model, rubber mould, wax injection, tree assembly, investment, burnout, casting, and cutting.

Where it goes wrong

Wax quality and burnout. Most porosity problems trace to one of those two.

The roles

Wax setters, tree assemblers, furnace and casting operators. Entry is possible without bench training.
