Vacuum Casting FAQs
What is vacuum casting used for?
Vacuum casting is mainly used for low-volume prototype manufacturing, cosmetic prototypes, functional testing, and production-like plastic parts before injection molding.
Why Choose Vacuum Casting?
Vacuum casting offers fast turnaround, flexible material options, production-like finishes, and cost-effective low-volume manufacturing.
Is vacuum casting expensive?
Vacuum casting uses silicone molds instead of steel injection molds, significantly reducing upfront tooling costs.Vacuum casting is generally considered a cost-effective solution for low-volume prototype manufacturing compared to injection molding.
What Factors Affect Vacuum Casting Quality?
Master pattern quality directly determines casting surface finish and dimensional accuracy
How to Select Vacuum Casting Materials for Product Prototypes?
Resin selection allows matching shore hardness, color, and mechanical properties to production materials
