Our Vacuum Casting Services
Levying on a strong supply base and in-house capabilities, Formioo offers vacuum casting for quick prototyping and small-series, high-accuracy production. Utilizing high-grade resins and precise molds, we ensure detail accuracy of ±0.05mm, with several surface finishing options. It is cost-effective to produce and provides quick turnaround to the level demanded by today’s injection molding.
Well-suited to the prototype, the method creates accurate, cost-effective parts with subtle surface details quickly by vacuum-supported resin casting.
This process provides outstanding dimensional tolerances and surface finish, best suited for functional testing and small-batch production of intricate parts.
Designed for end-product components, this process provides high-strength, high-grade parts with mechanical and aesthetic industry standards.
Optimized for mass production, multi-cavity casting uses multiple molds in one cycle to deliver consistent quality in high volumes of parts.

Vacuum Casting Materials
Polyester Resin
Quick cure and smooth surface finish, polyester resin is well suited for the production of decorative pieces and intricate models. It is applied in automotive emblems and consumer product model prototypes, finding a balance between cost and performance.
- Mill Lead Time: Up to 5 days
- Color: Translucent or pigmented options
Acrylic Resin
Renowned for its weather resistance and visual attractiveness, acrylic resin is a great choice for making transparent or colored decorative components. Due to its superior finish and clarity, it is used in display models and lighting.
- Mill Lead Time: Up to 4 days
- Color: Clear, colored, and matte finishes
Polyurethane Resin
Low viscosity and extremely fine reproduction of detail make it very suitable for vacuum casting, particularly rapid prototyping and low-volume production. It has wide application in automotive trim and consumer electronics enclosures for thin surface finish as well as resistance.
- Mill Lead Time: Up to 5 days
- Color: Customizable finishes available
Epoxy Resin
Having improved strength and transparency, epoxy resin provides high-performance structural components and optical components. Its excellent adhesion and low shrinkage enable precise, detailed molds for functional models and end-use applications.
