Vacuum Casting Services for Rapid Prototyping & Low-Volume Production

Release time:

2026-04-30 16:27

Vacuum casting is a rapid, low-cost technique for small-batch production, widely used in product development and prototyping.

In today’s fast-paced product development cycle, speed, flexibility, and cost control are critical. Vacuum casting—also known as urethane casting—offers an efficient solution to bridge the gap between prototyping and mass production.

From silicone mold creation to high-quality polyurethane (PU) parts, our vacuum casting process delivers precision, consistency, and excellent surface finishes, making it ideal for functional testing and small-batch manufacturing.

What is Vacuum Casting?

Vacuum casting is a manufacturing process where liquid polyurethane is poured into a silicone mold under vacuum conditions. This eliminates air bubbles and ensures highly detailed, defect-free parts.

Using a master model (typically CNC machined or 3D printed), we create silicone molds that can produce multiple identical parts with consistent quality.

Our Vacuum Casting Capabilities

Based on the production process shown:

High-precision master models (CNC machining or 3D printing)
Silicone mold fabrication for complex geometries
Vacuum casting under controlled conditions
Batch production with consistent quality output
Post-processing & finishing (painting, texture, assembly)

We support a wide range of industries including automotive, electronics, medical devices, and consumer products.

Key Advantages of Vacuum Casting
1. Cost-Effective for Low Volumes

Compared to injection molding, vacuum casting requires no expensive tooling, making it ideal for 10–100+ units production runs.

2. Fast Turnaround Time

Silicone molds can be produced quickly, enabling parts delivery in as fast as 7–10 days.

3. Excellent Surface Finish

The process captures fine details, textures, and complex geometries with smooth, high-quality surfaces.

4. Material Versatility

Choose from a wide range of materials:

ABS-like
PC-like
Rubber-like (elastic)
Transparent materials
5. Ideal for Product Validation

Perfect for:

Functional testing
Design verification
Market samples
Pre-production runs
Typical Applications
