3ERP is fully capable of handling your vacuum casting and silicone molding needs. With years of expertise in the field, we can fabricate your plastic parts to the highest standard, as well as cost-efficient and with fast turnarounds.

Advantages of Vacuum Casting

1 Fast turnaround

3ERP can provide up to 20 parts in 15 days or less, depending on part specification and volume.

2 Affordability

Silicone molds are less expensive than the tooling used for injection molding, resulting in low prices.

3 Capable of producing large parts

Depending on the type of equipment used, vacuum casting can create very large parts.

4 Superior surface finish to injection molding

The vacuum process removes air bubbles and allows the material to capture fine details.

5 Color options

Coloring pigments can be added to the resin for a variety of color options.

6 Repeatability

Silicone molds can be used around 20 times before they need replacing.

Vacuum Casting FAQ

Why would I choose vacuum casting over injection molding?

Vacuum casting is a more affordable alternative to IM, especially in low volumes. It also offers unique advantages like an excellent surface finish.

Can I make production-quality parts using vacuum casting?

Vacuum casting is best for making visually impressive prototypes, but it can also be used for non-mechanical end-use parts like cases and covers.

What happens to the silicone mold(s)? Can I keep them?

The silicone molds used in vacuum casting have a short lifespan, typically around 20 moldings, so we dispose of them after use.
