Low-volume economics
Production tooling may not be justified for early market or engineering quantities.
Engineering & Manufacturing in China
Vacuum Casting Services for OEM Prototypes & Bridge Production
Produce high-quality polyurethane parts from silicone molds for appearance validation, functional testing and low-volume bridge production before injection tooling is ready.
Buyer Challenges
Bridge the gap between one-off prototypes and production tooling
Appearance needs
Stakeholder and customer reviews require production-like color and finish.
Material simulation
Parts need rigid, flexible or transparent behavior closer to molded plastics.
Tooling schedule
Bridge parts may be needed while production tooling is still being built.
Manufacturing Capabilities
Polyurethane vacuum casting capabilities
Master pattern
SLA or CNC masters prepared around surface and dimensional requirements.
Silicone tooling
Controlled mold construction for short-run repeatability.
Material selection
Rigid, flexible, clear and colored polyurethane systems.
Casting production
Low-volume parts for validation, field trials and bridge supply.
Finishing
Color matching, painting, texture, inserts and assembly.
Inspection
Visual, dimensional and functional checks aligned with prototype purpose.

Manufacturing Case Study
A practical production challenge and documented result
- Product type
- Handheld diagnostic device housings
- Material
- ABS-like polyurethane
- Challenge
- The OEM needed 30 presentation-quality housings before injection mold completion.
- Solution
- A finished SLA master and silicone tools were used to cast color-matched housings with inserts.
- Result
- The team completed customer trials and packaging validation without waiting for production tooling.

Frequently Asked Questions
Questions from engineering and sourcing teams
How many parts can a silicone mold produce?
Tool life depends on geometry, material and finish; the project plan should match quantity and acceptance requirements.
Can vacuum-cast parts match a production color?
Color matching and painting are available, with practical tolerance based on material and finish.
Is vacuum casting suitable for functional testing?
Yes, when the selected polyurethane properties reasonably match the intended test loads and environment.
