When is vacuum casting used?

Vacuum casting is suitable for prototype and end-use parts. It can be used for concept models, visual models, pre-production prototypes, functional test prototypes, models for thermal and air flow testing, and for assembly line trials.

For functional prototypes, vacuum casting is excellent for adding elastomeric sealing features to parts produced by other prototyping technologies, or for overmoulding metal components.

Polyurethane is sufficiently robust for end-use parts – for elastomeric seals, for example, or overmoulded ergonomic grips or complex geometries.

Vacuum casting is used in industries as diverse as  Medical, Life Science, Automotive, Aerospace and general manufacturing.

Vacuum casting capabilities

Our vacuum casting chambers and ovens achieve excellent quality and repeatability thanks to electronic differential pressure control systems and automatic silicone degassing.

The maximum cast weight is 1400g and the maximum mould size is 450 x 470 x 400 mm.

Depending on the part geometry and polyurethane grade, moulds are reusable up to 25 times.
