ZY Vacuum casting

—— Perfect solution for production quality parts

—— Your professional and reliable partner

ZY Vacuum Casting

Zhiyou has fully capabilities to handle your vacuum casting and silicone molding demands. With years of expertise in this field, we’re able to manufacture your plastic parts with high quality standard and competitive price. Zhiyou could help you with all complex work of custom products from prototyping to production.


Vacuum casting (also named urethane casting) is an economical solution for low-volume production of plastic parts, and casting resin materials are closely simulated final molded parts or products.

Advantages of Vacuum Casting

1. Fast turnaround：

2. Economical in both cost and time:

Silicone molds are less expensive than metal tools, but more easier and faster to make
Usually 2 weeks or less to make parts ready

3. large part making capacity:

4. Surface finish options:

Very large parts.can be produced shortly, supported by large vacuum casting machine
Different Colors, Textures & Finishes Available

6. Excellent Physical Properties

5. Repeatability:

The casting parts have good Physical Properties for functional purpuse
Silicone molds can be used around 20 times before replacing.

Casting Resin Material Available

Casting resins are polymers with a wide range of properties and use. Zhiyou offers different kinds of casting resins materials to meet your applications, including Axson from France and Hei-Cast from Japan. Materials with certain properties are similar to engineering production plastics, such as ABS, PMMA, PC, PP, PA, etc. Some special materials are also available, like high-temperature resistant (120℃ or 200℃) or fire-resistant (UL94-V0).

Our Vacuum Casting Capability

How It Works (3 steps)  

Step 1. Master model building – CNC machined or 3D printed via SLA or SLS 

Step 2. Silicone mold making – liquid silicone is poured around the master model and fully cured. Once dried, the mold is cut open and master is removed 

Step 3. Casting parts – the casting resin is poured into the cavity to create products, like replicate

Detailed steps as below

Here are some examples of our previous projects

Pattern Processes

----CNC machining & 3D printing

The master model will be made by CNC machined or 3D printed via SLA or SLS,per part size and structure, material, and surface requirements.
