Introduction to vacuum casting Vacuum casting allows the production of small batches of high quality mouldings in a range of polyurethane resins that replicate the performance of engineering plastics without the high costs of hard tooling associated with injection moulding. The process starts with making a mould by encapsulating a master model in two-part liquid silicone rubber. A vacuum is then applied to remove any trapped air, then it is cured in an oven. Master models can come from a number of 3D printing technologies including stereolithography. Once the silicone is cured, the mould is...

Benefits of vacuum casting When vacuum casting was first introduced to the market in 1987, the concept of ‘24 hours from pattern to part’ was nothing short of a revolution, transforming plastic prototype production. As mass-customisation takes hold, vacuum casting enters a new phase. Significant developments in polyurethane resin and materials, and the addition of thermoplastic nylon casting capability using Renishaw’s externally mounted nylon module, enables vacuum casting to become a viable ‘small batch’ manufacturing technology. Benefits at a glance: • From master model to multiple...

Benefits of vacuum casting Benefits continued: • Good mould life – moulds are capable of producing up to 50 parts before retooling is required, making vacuum casting the perfect choice for small batch production • Versatile – resin types can be changed very quickly reducing system downtime • Master models can come from a range of sources, the most common being stereolithography models, but increasingly the accessibility of 3D printers has become a useful source • Highly complex shapes can be accommodated through multisegment moulds • The confidence we have in the reliability of our own...

Vacuum casting applications Everything from industrial components, to consumer products, lenses and small batches can be produced using the vacuum casting process. Typically, between 30 and 50 colour matched parts can be produced from a single mould with first parts available within 24 hours. Typical applications at a glance: • High quality prototypes for product design verification • Small batch production for bespoke products • unctional nylon components in a range of grades – F particularly good for living hinges and high strength requirements • Automotive ‘hot test’ and specialist...
