Investment casting also known as lost wax casting is a technique used to create intricate and detailed shapes for jewellery and art casting. This technique has been used for centuries and is still widely used today due to its versatility and precision.
Investment casting involves creating a wax or resin model of the desired shape. The wax model is then encased in a ceramic shell and heated in a kiln to melt the wax out of the mould. Molten metal is then poured into the cavity creating the final casting. Once the metal has cooled and solidified the ceramic shell is broken away to reveal the final casting.
There are several techniques used to create the wax or resin model for investment casting. One of the most common techniques is wax carving where the model is carved by hand using a wax carving tool. This technique is often used for creating intricate designs and patterns.
Another technique is 3D printing, where a 3D digital model is created and a 3D printer is used to create a physical wax or resin model. This technique allows for precise and accurate models to be created quickly and easily.
In some cases a mold can be made of an existing object or shape which is then used to create a wax model. This technique is often used for creating duplicates of existing objects or shapes.
Investment casting is a versatile technique that can be used to create a wide range of jewellery and art-casting objects. Here are some examples of investment casting for jewellery and art casting.
