3D printing may be popular for prototyping today as it delivers high-quality parts quickly and cost-effectively. But before its widespread use, the automotive industry relied on methods like vacuum mould casting to make production-grade prototypes.
Though it’s not as advanced or high-tech as 3D printing, vacuum casing is still a valuable alternative for making high-quality aesthetic and functional models. Plus, it does not involve the lead time and costs of production tooling, making it worth considering for casting small or large items fast. Just ensure it’s offered by a trusted service provider such as HLH Proto.
HLH Proto is one of the leading companies specializing in vacuum casting. Also known as cast urethanes, vacuum mould casting is possible for a wide range of projects, including car bumpers. And with modern prototyping technologies, HLH can make the process faster and more cost-effective. Their vacuum casting process follows three stages:
Creating the master model – This can be 3D-printed using selective laser sintering (SLS) or stereolithography (SLA), or CNC-machined, depending on the project’s requirements.Making the silicone tool – After making the master model, liquid silicone is poured around it and left to cure. Once it’s dry, the master is removed from the mould, resulting in a cavity.Casting – Resin is placed in the cavity and cast to make the production-grade replica
How vacuum casting helps the automotive industry
Prototyping for the automotive industry requires the highest level of accuracy, especially where precise dimensions are critical for the part. Plus, the process must be repeatable and quick, even for intricate designs. As long as the material or part won’t be exposed to too much pressure or high heat, vacuum mould casting should be a suitable method for making its prototype or end-use version.
Vacuum casting also provides the following advantages to automotive part designers and engineers:
Make low-volume parts quickly and cost-effectivelySelf-coloured, production-like partsRubber-like parts and over-mouldsAccess to more materialsHigh-quality parts for market testing and rapid iterations
