Frequently Asked Questions

What is vacuum casting used for?

Vacuum casting is ideal for creating small batches (1–100 units) of high-quality prototypes or end-use parts using silicone molds. It's cost-effective and fast, perfect for functional testing and market validation.

How long does it take to get a prototype?

Typical lead time is 5–7 days from CAD approval, depending on complexity and finishing requirements. Express services are available.

What materials do you support?

We offer a wide range: ABS-like, PP-like, PC-like, transparent, silicone, nylon (SLS), and metal (SLM). CNC supports aluminum, steel, brass, and plastics.

Can you help with design optimization?

Yes! Our engineering team provides free DFM (Design for Manufacturing) feedback to improve manufacturability, reduce costs, and ensure quality.

Ready to Start Your Project?

Whether you need a single prototype or low-volume production, our team is ready to assist.
