How to use Vacuum Casting with Silicone Moulds? When mass-producing in China, many clients have inquiries for samples in bespoke shapes. This requires factories to produce a mould in order to create the sample and then start mass-production. Opening new mould can be very expensive and take weeks to make – especially for plastic material. We recently posted a case study about opening moulds in China. Check it out below.
One more tricky point is that once the mould is finished, there is not much space for changing the shape and size of it. That is why we are offering alternative option – Vacuum Casting with Silicone Moulds
Silicone moulds provide a fast way to produce prototypes of products. Producing a vacuum cast with a silicone mould is cheap, starting from several hundred dollars, depending on the design and size. Silicone is ideal for casting as it can replicate intricate detail. It is also reasonably cheap to use and produces moulds that are flexible, durable and can be reused to produce a number of prototypes.
Creating silicone moulds is a quick way to create multiple prototypes. The mould can be cast on a new or existing product. If you want to create a silicone mould of an existing product, casting can be done practically straightaway. If you want to create a mould for a new product or prototype then the product will have to be produced by CNC. In order to create a mould, the following process has to be undertaken.
Important note: when vacuum casting with silicone moulds 8 – 10 prototypes can be created from a single mould, before it starts to become less effective.

There are plenty of casting processes such as die-casting, investment casting, plastic casting, and sand casting, etc. All the different types of casting will provide their own unique benefits in manufacturing.
Yes, it is possible by casting silicone into a silicone mould. A two-part mould and release agent will be required.
A master model is produced with a high-quality surface finish and the silicone mould will be cast around the master copy under vacuum to avoid air bubbles from forming. The silicone mould is cut into parts and the master model will be removed after the curing process.
