Vacuum casting is a tried-and-tested process for producing multiple high-quality models, prototypes and low-volume end-use parts for a full scope of applications, including form, fit and function testing.
The vacuum-casting process allows for parts to be produced using a wide range of polymers (rigid and flexible), which, for prototype and low-volume production applications, can be selected to most closely mimic production material properties. Parts can be pigmented, painted or given a specialist finish, such as EMC shielding and fire-retardant coatings. They can also have threaded inserts.
The process requires a master model from which to create the cast or mould. There are many ways of creating this, and one of the most successful methods is to use the SLA (stereolithography) process; which Ogle has extensive experience of, with a number of SLA machines in-house. The SLA process produces extremely accurate models – a prerequisite for vacuum casting – in a variety of resins that make them ideal for vacuum casting. The expertise and experience of the team at Ogle ensure that the very best results are achieved every time.
For certain applications, where quantities, size and material requirements are appropriate, the process can also be used for small batch production runs.
Variety of materials (not limited to):
Our work with vacuum casting is as varied as the industries that benefit from the process. We have worked with the medical sector as well as in product development.
