Casting

The ultimate process of lost wax casting - pouring metal into the mould.

How we cast your jewellery

So, you had this great idea for a piece of jewellery, a bit of model engineering, a bagpipe key and all the rest. So where do you go from there? These are often the key starting points we begin with casting your ideas:

Preparing the Metal

We only buy our metal from the most reputable bullion dealers. Then we know that the alloy is spot on. It comes to us, supplied in grain form. All our sprues are recycled in-house and made back into clean grain. This is mixed with new bullion which gives us first class results with minimal wastage. This is done with all our metals. Cleanliness is key - we barrel polish all of our grain before casting.

Weighing out the Metal

So, how much metal do we put in each flask? We do a separate melt for each flask so we need to know the amount of metal needed accurately. By dint of weighing the waxes and a bit of Excel skullduggery we calculate the weight of metal , like using the calculator on our site. Before we start casting we have a tub of metal numbered, for each flask.

Melting and Pouring the Metal

We melt all of our metal in a Closed casting machine. This covers the metal with inert gas (nitrogen) to keep all of the oxygen away. The metal is heated in an induction furnace and when the metal reaches the required temperature, it's dropped into the flask with an extra shove of extra pressure nitrogen gas. We leave it for a couple of minutes to freeze then removed from the machine to cool in the air.

Quenching and Cleaning the Castings

When the metal reaches "black heat" the flask is plunged into a tank of cold water and swished around until all the boiling stops. By this point, most of the plaster is deposited in the bottom of the tank. The flask and castings are moved to an enclosed pressure washer where they are carefully blasted clear of plaster. A swift 5 minutes in some weak acid to soften any oxides - a good wash and into the workshop for...

Pin Polishing

The individual castings are snipped off the central core (tree trunk) and placed in a magnetic pin polisher which gives them a nice, bright, shiny finish. Ready for sprue removal, inspection and dispatch.
