Automotive component parts: the vacuum casting advantage

There’s no need to tell automotive design and mechanical engineers just how vacuum casting can be used for prototyping and low-volume production of plastic parts for their vehicles…. Everyone pretty much knows that vacuum casting is a manufacturing process that uses silicone moulds and polyurethane resins to create high-quality plastic parts that closely mimic the properties of injection-moulded parts.

But… they might need reminding just how versatile and valuable this process is when it comes to producing parts for testing and refining designs before committing to expensive injection moulding tooling. And for low runs of production, it can save both time and money.

At Paragon Rapid Technologies, our technical experts are no strangers to the pressures you are under to produce precise, quality parts and prototypes under serious time constraints. We aim to be a dependable, trustable source of advice and solutions, ensuring that you have the relevant materials and technology information, process insights and design recommendations, should they be necessary, to deliver a perfect part, every time.

Our automotive customers have trusted us with the development and production of:

Interior trim components: Vacuum casting can be used to produce interior trim components such as door handles, knobs, and dashboard panels.
