Next up is how I finish my pieces after I pick them up from Taba. It's a great way of being able to make multiple pieces of the same thing again and again. Here are some wax pieces straight from molds before being put on the tree. Once you have the wax pieces, they are added to the 'tree' and you go back to where you were above. This is then used to create wax pieces, by pouring molten wax in the molds, you can easily get multiples of one piece this way. If you were to bring in a piece that was already made (either a 3D printed design that was printed in plastic or another material, or piece you already created in metal that you want more of), they would add a sprue and make a silicone mold from it. Here's the ring that I picked up in it's raw state with the sprue. The sprues are the cut off and the piece is ready for the customer to pick up. I also bought injection wax off of the internet, it holds heat well and cools very hard. I bought the letter m mold off of eBay, you can always carve the wax but I wanted to make multiple molds in a short period of time. Plaster Made of such materials as gelatin, vinyl. Step 1: The first step is to decide what you want to cast, I chose to make handles for a china cabinet that I had made my wife. When the pieces are cool, the plaster of Paris is washed off the tree to leave the metal pieces. Casting and molding These are used for producing a single cast from a soft, plastic original, usually clay. The metal needs to be hot enough to be in liquid forms so that it can be centrifugally thrown towards the inside mold wall, where it solidifies after cooling. Once dry, the wax is melted out, leaving a cavity that looks like the pieces in the tree. But since I know this way, this is what I'll describe it's called centrifugal casting.Ī wax sprue is added to the piece and together with other pieces being cast in the same metal, a 'tree' is formed.Ī metal flask is placed over the tree and a plaster of Paris type material called investment is poured into the flask. This is the process of wax casting that I was taught at a class, but mot likely it is a different process at Taba. They use metal from United Precious Metal Refining, which are environmentally responsible, they use recycled fine silver and are of great quality. I use Taba Casting, they're friendly, have competitive prices and I like the metal they use. I'm lucky to live a short distance to Manhattan and the Diamond District, so there are a few casters to choose from.
