Why Choose Vacuum Casting for Low-Volume Production?
Vacuum casting offers a cost-effective alternative to hard tooling for projects that do not yet require the high initial investment of steel injection molds.
Low Tooling Costs
Silicone molds are significantly cheaper and faster to produce than metal molds, making them perfect for design validation and market testing.
Material Versatility
We work with polyurethane resins that mimic the properties of ABS, PP, PC, and rubber-like materials, allowing you to test functional parts under real-world conditions.
High Cosmetic Quality
Vacuum casting reproduces intricate details, textures, and smooth surfaces, providing parts that are suitable for trade shows, investor presentations, and final user testing.
Design Iteration
Because the tooling is less expensive, you can modify your design between batches without the prohibitive costs associated with modifying steel injection molds.
Supported Materials & Applications
We support a wide range of resin types tailored to your specific mechanical requirements, including rigid, flexible, clear, and flame-retardant materials.
Common Applications
Snap-fits, enclosures, and moving parts tested under real physical load.
Supplying parts to meet immediate shipment needs while waiting for mass-production tooling.
High-finish components for trade shows, investor demonstrations, and product launches.
Durable covers, bezels, and panels for medical, laboratory, and measurement equipment.
How to Get Started
Our engineering team reviews every file for DFM (Design for Manufacturing) to ensure your part is optimized for the vacuum casting process before production begins.
CAD File Submission
Provide your 3D CAD files in STEP, STP, or IGES format alongside 2D drawings for critical tolerance specifications.
Define Specifications
Include material hardness (Shore A/D), color (Pantone/RAL), required surface finish (texture/gloss), and quantity.
DFM & Fast Production
Our team verifies draft angles and wall thickness, builds the SLA master, casts silicone tooling, and delivers in 5-10 days.
Ready to Start Your Project?
Upload your CAD files or send your drawings and specifications for a rapid quotation and technical DFM evaluation from our engineering team.
Every submission is checked for proper wall thickness (min 1.5mm recommended) and parting line placement before mold pouring.
