This powerful and versatile manufacturing technique leverages the advantages of silicone moulds and vacuum technology. These components are leveraged to produce high-quality intricate parts, but at a price lower than traditional methods. 

Also known as urethane casting, vacuum casting is a cost efficient solution with design flexibility and the ability to replicate complex geometries with high precision. 

How vacuum casting works

To start the vacuum casting process, a master model is created, which usually happens via CNC machining or 3D printing. This model is then leveraged to fabricate a silicone mould, serving as the negative for casting the final parts. The three primary steps of vacuum casting are explained below:

1. Master model creation: The first step involves creating an accurate master model by using either 3D printing or CNC machining. This model serves as a template for the silicone mould. It is essential to achieve a smooth and flawless surface finish, as the final product will replicate all the details from the master model.
