Vacuum Casting & Prototyping Services

INTRODUCTION

What Is Vacuum Casting. Why Does Your Business Need It?

Vacuum casting is a rapid prototyping process where liquid polyurethane resins are poured into silicone molds under vacuum to eliminate air bubbles and achieve high surface detail. The result is a part that closely replicates the material properties and appearance of injection-molded products, without the cost or lead time of hard tooling.

It is widely used in product development, design validation, functional testing, and low-volume production across industries including consumer electronics, automotive, medical, and industrial equipment.

Key Business Outcomes:

• Production-accurate prototypes at a fraction of tooling cost

• Fast turnaround for design validation and client approvals

• Low-volume manufacturing without injection mold investment

• Wide material simulation including rubber, ABS-like, and clear resins

NDA-Protected and IP-Secure

Full confidentiality agreements available. Your designs, files, and intellectual property remain completely protected.

HOW WE WORK

Our Vacuum Casting Engagement Process

A structured, engineering-driven process ensures your parts are delivered on time, within tolerance, and ready for their intended use.

01

Discovery

You share your CAD files, drawings, or design brief. Our team reviews your geometry, material requirements, surface finish needs, and delivery timeline.

02

DFM Review and Quotation

We perform a design for manufacturability review and provide a detailed quote with recommended resin grade, finish options, and lead time.

03

Master Pattern Preparation

We prepare or 3D print a high-accuracy SLA or SLS master pattern to the required surface finish quality for silicone mold production.

04

Silicone Mold Fabrication

The master pattern is encased in liquid silicone under controlled conditions. Molds are cured, trimmed, and validated before any casting begins.

05

Vacuum Casting and Post-Processing

Parts are cast under vacuum using your specified resin grade, then demoulded, post-cured, finished, and inspected against your drawing before delivery.

06

Quality Inspection and Delivery

Each part is dimensionally and visually inspected before secure packaging and global delivery with full inspection documentation.

FAQ SECTION

Frequently Asked Questions

What is vacuum casting in prototyping?

Vacuum casting uses silicone molds and polyurethane resins to produce high-detail, production-accurate prototype parts under controlled vacuum pressure. It eliminates air voids and delivers injection-molded quality without expensive hard tooling.

How many parts can I get from one silicone mold?

A standard silicone mold typically yields 15 to 25 quality parts depending on part geometry, resin material, and surface finish requirements. Additional molds can be made from the same master pattern to scale production.

What materials can be simulated with vacuum casting?

Vacuum casting simulates ABS, polypropylene, polycarbonate, PMMA, TPE, and rubber-like materials using specialized polyurethane resin grades. Material selection is matched to your functional testing and visual requirements.

How fast can I receive my vacuum cast prototype?

Standard lead times are 5 to 10 business days from approved design files to delivery, depending on part complexity, quantity, and finishing requirements. Expedited services are available for time-critical programs.

Is vacuum casting suitable for functional testing?

Yes. Polyurethane resins closely replicate the mechanical and thermal properties of production thermoplastics, making vacuum cast parts suitable for fit checks, ergonomic testing, assembly validation, and limited functional testing.

What file formats do you accept for vacuum casting projects?

We accept STEP, IGES, STL, SolidWorks, Rhino, and PDF drawing formats. Our engineering team reviews all files for castability and performs a DFM check before proceeding to mold fabrication.
