Vacuum casting

Vacuum casting or vacuum duplication ensures faithful reproduction of a model using a silicone mould. It is incontestably the most economical solution for the production of short series: prototype parts, pre-production or end parts. The resins used offer the advantage of similar properties to the plastics used in injection moulding (thermal, mechanical, appearance).

Vacuum casting

Manufacturing process


After creating a master (or model) in SLA stereolithography, a silicone mold is made. The impression left by the master in the mold is filled with polyurethane resin using a vacuum casting machine. The vacuum created in this machine prevents the presence of large quantities of bubbles in the material, which could weaken the part. The service life of a mold can range from 10 to 25 parts, depending on the complexity of its geometry and the type of resin used.
