Are you right for the kind of prototype I need?

We don't just pour resin; we select polyurethanes, silicones, and epoxies based on your specific mechanical needs. Whether you need high-impact resistance or specific thermal properties, the choice is driven by your prototype's intended use.

Most projects are completed within two to three weeks of pattern approval. If you're on a critical sprint, we offer rush schedules for urgent R&D-but we'll always give you a firm, dependable timeline upfront so you can manage your stakeholders without surprises.

Can Vacuum Casting produce biocompatible parts for medical device testing?

Yes. We utilize a range of advanced polyurethane resins that mimic production-grade plastics, including biocompatible and clear resins suitable for medical housing, and fluid handling components. Our Vacuum Casting process is ideal for creating small batches (10–50 units) for clinical trials or user testing where material performance must mirror the final injection-moulded product.

What tolerances can you hold?

We maintain tolerances of plus or minus 0.5mm on most dimensions. Complex geometries may require tighter control in specific areas. We'll discuss your exact requirements during the planning phase.

Why not injection mould?

Vacuum Casting excels for runs of fifty to five hundred units. It costs far less than injection moulding tooling at these volumes. This makes it ideal when you need real parts but not mass production.

What about surface finishes?

We match any VDI finish or gloss, satin, spark finishes. Post-processing includes painting, coating, and assembly. Your parts arrive ready to evaluate or use.

How does Vacuum Casting compare to 3D printing for consumer goods prototyping?

While SLA 3D printing is excellent for initial form-finding, Vacuum Casting is the superior choice for 'box-ready' consumer prototypes. It allows for self-coloured parts (pigmented resin), overmoulding (soft-touch grips), and superior surface finishes that require less post-processing. It bridges the gap between a 3D-printed concept and mass-market injection moulding, providing high-fidelity models for marketing photography and stakeholder presentations.

Process

How Vacuum Casting works

We create a silicone mould from a master pattern, then cast resin under vacuum to reduce bubbles and improve detail. The result is high-quality prototypes and small batches with excellent surface finish and mechanical properties.

Benefits

Why Vacuum Casting is often the best next step

It gives you small batches that look and feel closer to production, without committing to full tooling too soon.

Fine detail, held accurately

Small features and critical dimensions transfer cleanly from the master pattern to the finished part.

Materials chosen for the job

Polyurethane, silicone and epoxy resins selected to match the performance your prototype needs.

Fast turnaround for testing

Most vacuum casting projects are completed in two to three weeks, so parts get into testing sooner.

Why Choose Vacuum Casting?

Simulated Injection-Moulded Parts: Enjoy the quality and precision of injection-moulded components without the high costs. Our Vacuum-Casting process delivers highly accurate parts with a flawless tool-surface finish that is self-coloured, achieving professional-grade results in less time.
Bubble-Free Casting: By operating under vacuum conditions, our process eliminates air bubbles during moulding, resulting in parts with smooth and blemish-free surfaces for enhanced quality.
Complex Geometries: Vacuum Casting excels in replicating intricate designs and delicate features, making it ideal for components with complex shapes.
Material Transparency Options: We can craft parts using materials with various degrees of transparency - fully opaque, translucent, or completely clear-to suit your design and aesthetic requirements.
Self-Coloured Castings: Using advanced resin technologies, we produce self-coloured castings that eliminate the need for additional painting or finishing steps. These castings offer vibrant, consistent colours throughout the part, ensuring an aesthetic and professional appearance right out of the mould.
Efficiency and Savings: For projects requiring fewer parts, Vacuum Casting ensures rapid processing while minimising costs, allowing you to focus resources on innovation.
Low-Cost Tooling: Silicone moulds used in Vacuum Casting are faster and more affordable to produce compared to metal moulds, making it a cost-effective option for prototyping and low-volume production.
Surface Finish Versatility: Whether you need a glossy, matte, or textured surface, Vacuum Casting offers exceptional flexibility to achieve the desired finish.
Wide Material Range: We offer a diverse selection of resins, including biocompatible resins for medical applications and thermoset-simulant resins that replicate production materials. Whatever your project demands, we provide solutions tailored to your unique requirements.
