Vacuum Casting

Epoxy resins are mixed under vacuum in a chamber, this is then cast into the silicone tool and cured to form your part.

Silicone Tooling
A pattern is taken from an SLA master, feed, vents and a split line is added and liquid silicone is then poured over the master under vacuum, left to cure which then creates a soft tool for casting into.

Why Use It
Batch Production - It is ideal for producing low volume production runs or ‘first off’ production samples. Resins can also be mixed to produce the material characteristics of the component you require for production.

Aesthetics - Parts can be produced and replicated exactly from the master, so spark finishes and gloss surfaces are picked up in this method. We can also pigment the parts to any colour you want.

Functionality - Parts vac cast can be fully functioning, with snap fits, heat resistant and rubber materials available. We can also produce waxes for investment casting and cast directly into the tool low melt alloys. For further details on casting resins please contact us on the details below.

What to Consider
Batch Production - As the silicone tool is a soft tooling method it has a limited life of around 20-25 casts this depends on what material is cast into the tool. If you require functional prototypes;

Have you considered - SLS Prototyping?
