Great Light Vacuum Casting Service Advantages

Production Quality at Low Volumes
This process is a quick, cost-effective way to produce 10-200 units with production-level quality. Typically, each silicone mold will produce 20 castings.

Complex Elastomeric Parts
Vacuum casting is ideal for prototyping elastomeric parts such as complex gaskets and overmolds on rigid parts.

High Level of Detail
Vacuum casting allows for almost limitless complexity, including sharp internal corners unachievable with CNC machining, and designs without draft or uniform wall-thickness that can’t be injection molded.

TECHNOLOGY OVERVIEW

- What is Vacuum Casting -

About the Vacuum Casting Process

Vacuum casting (also known as RTV molding, cast Vacuum, and silicone molding) is a fabrication method that uses silicone molds to produce production-quality plastic parts.

Vacuum Casting production consists of three main steps:
‍
1. Build a master pattern using 3D printing or CNC machining
2. Build the mold by pouring platinum silicone around master
3. Pour liquid polyurethane resin into mold, create polyurethane casting under vacuum

Advantages of Vacuum Casting

With Vacuum casting, you can get production quality parts at low volumes and without the high costs and lead times of steel or aluminum tooling. This is helpful for bringing new products to market where you may want production-grade products to test with new customers and markets and validate your design hypotheses before making a substantial investment to scale manufacturing.

Vacuum Casting Design Considerations

If you are familiar with designing parts for injection molding, you can apply the same best practices and rules of thumb to design parts for Vacuum casting.
