KARV Automation offers industrial-grade vacuum casting services to cater to all custom manufacturing requirements. Our in-house workshops are facilitated with advanced machines to design, manufacture, and test products for your small-batch production.
With our modern equipment, we deliver products with a maximum size of up to 2.5 meters long with an accuracy of up to ±0.1 mm. We offer over 40+ different industrial-grade materials including rubber, ABS, polypropylene, HDPR, polyamide, PMMA, and some of them have properties similar to injection molding materials. Our team is committed to faster product delivery with an ETA of as minimum as one week. The specific number of parts per mold ranges from 10 to 30 units depending upon complexity.
Vacuum casting services, also known as urethane vacuum casting, is a highly adaptable process that can produce parts with complex geometries. It is an ideal production method when the number of pieces is limited and high-quality is the requirement. We offer highly-customized vacuum casting services worldwide.
Vacuum casting in plastic or any other material comprises four significant steps that complete the entire process — the steps include:
The vacuum casting process needs a high-quality master model for creating replicas. This model can be an industrial part itself, or engineers can create a prototype using SLA technology. This master model comprises accurate details and dimensions.
The liquid silicone is poured and then cured under vacuum and then cut into two halves to get the master mold ready.

The molds are then filled with the required material, and the resin copies the material’s characteristics. The resin is mixed with coloring pigment to achieve specific color properties. Also, you can provide us with any color code to achieve the desired finish product.
Once the mold is filled with the material, it is then placed in the vacuum chamber to ensure there are no air bubbles inside the mould. This step lets engineers check the final product is not damaged.
For the final curing process, the resin is placed in the oven, and the mold is cured at high temperatures. The silicone mold is removed from the resin mold, and it is used for making more parts. Once the final object is out of the mold, it goes for post-production.

As compared to injection-molded components, the vacuum mold casting parts are of more intricate details. Vacuum casting is the best-fit method for function testing and for producing items in a small batch. It is an ideal method for achieving surface finishing to match your product requirements. We at KARV Automation offer a wide range of surface finishing options to deliver you the best final product.
