Vacuum casting:


The polyurethane vacuum casting mould is a mold made of silicone rubber, usually based on the main mold created from CNC machining or our rapid prototyping service (SLA or SLS).This option is ideal for copying master replicas on 50 computers.The resolution of the original is very high.

The process:


We can use our own prototype service or model from the customer to create a master model.The model is placed in a chamber or in a casting box and filled with liquid silicone rubber.Once the silicone is cured, it can be cut open and the owner removed.Now there is a cavity that perfectly matches the owner's image.This cavity is filled with the casting material you choose.The vacuum is applied to the silicone mold, which effectively pulls the material into any gap in the mold.

Materials:


All kinds of polyurethane resin can be used for casting parts to meet your needs -- heat resistance,
Flexible, clear, rigid and so on.Many polyurethane can be colored in the mold or can be printed or printed later.

Advantages of vacuum casting:


Polyurethane vacuum casting produces high quality finished parts, almost equal to them.
Injection molding parts, do not bear related costs.Silicone is very good
To replicate complex features and dangling objects, 3D printing is difficult, and the surface can be extracted to produce a high gloss acrylic finish.It may even be possible to insert moulds into different materials or threads.The disadvantage is that the silicone mold is not durable, and cannot rely on the geometry of the parts to make more than 50 molds.
