Vacuum Casting is a mid-to-low production volume process for customers who need high quality, cosmetic finish, end-use parts in a fast turnaround. We not only produce vacuum casting plastic parts with production-level quality but also offer a wide range of finishing services and post-machining services to ensure your requirements of quality, exterior looking, performance, and color selection are met.

Introduction of Vacuum Casting Service

Vacuum Mould Casting is a good manufacturing method to produce great quality prototypes and low volumes of parts from soft silicone mould. Its big advantage when compared with injection moulding is that silicone ‘soft’ mold is made quicker and cheaper than metal ‘hard’ tool. The polyurethane parts from vacuum casting process in rapid prototyping are superior quality, precise and have the same great performance as the production parts.

Advantages of Vacuum Casting

Time SavingTime Saving

Typically, a silicone mold can cast about 15-25 parts. Also, soft tooling is cheaper and more time-saving than hard tooling.

Production QualityProduction Quality

The polyurethane vacuum cast parts have the same cosmetic and performance criteria with the production-level components.

SpeedSpeed

The molds can be made in 2 days, the polyurethane cast parts can be completed in 1-2 weeks, depending on the order volume.

Low CostLow Cost

A silicone mold is durable for 15-25 parts, making it affordable to produce mid-to-low production volumes when you would like to order 1 or 100+ pieces of parts.

Wide Material SelectionWide Material Selection

There is a wide array of rigid, flexible, rubber-like plastic materials available. The material can be tuned to your specific shore durometer from very soft (shore A) to very rigid (shore D).

A Wide Range of FinishesA Wide Range of Finishes

We offer a wide range of color options including clear, black, and Pantone/RAL color matching. We also provide a wide variety of custom surface finish options, which include sandblasting, plating and painting.

Common Vacuum Casting Applications

Consumer Testing

It is the best way to do consumer testing with a physical concept model. With advantages of cosmetic surface, precise dimension, production-level performance, rapid turn-around, competitive cost, polyurethane cast parts are ideal for customer testing such as for the aerospace plating company.

Low-Volume Manufacturing

The vacuum casting process can be done very quickly because the silicone molds which used to cast copies are made in a very short lead time. It is used a lot for low volume production runs with such a quick turnaround and cost effective price.

Rapid Prototyping

Vacuum casting process in rapid prototyping is not complicated. A silicone vacuum casting mould is last for about 15-25 copies, therefore it is easy and economical to verify designs or make any needed design changes. Moreover, we can pour different polyurethane materials into the same silicone mould, making it cost effective and time saving to test designs with a wide range of materials.
