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

15+ Years of Engineering Expertise

Deep domain knowledge across manufacturing, industrial, and product development sectors with a proven global delivery track record.

End-to-End Prototyping Service

From DFM review and master pattern preparation through casting, finishing, and quality inspection under one roof.

Wide Material Library

20+ polyurethane resin grades simulating rigid, flexible, transparent, and rubber-like production materials for any application.

Fast Turnaround, Globally Delivered

Standard lead times of 5 to 10 business days. Global shipping with tracked logistics and full documentation.

Strict Quality Inspection

Dimensional checking, visual grading, and inspection reporting against your drawings or specification on every order.

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.
