Surface Finishes

Surface Finishes for Vacuum Casting

With us, you can access a wide variety of surface finishes for vacuum-casted parts. We can create unique finishes tailored to your needs to achieve the parts’ hardness, appearance, and chemical resistance.

CreateProto Vacuum Casting 0014

High gloss

At CreateProto, we can create a highly reflective finish polishing the master pattern before we make the mold. You will get high transparency, making the parts ideal for lenses, cosmetic products, and different cleanable surfaces.

CreateProto Vacuum Casting 0015


With this surface finish, you won’t get a highly reflective finish to your vacuum-casted parts but sheen effects. We use gritty sandpaper to make the surface smooth and clean to bring the finish between matte and high-gloss.

CreateProto Vacuum Casting 0016

Matte Finish

Do you want a stain-like finish to your vacuum-casted parts? We can bring that through the sand or bead blasting process of the master pattern. This finish is ideal for handheld parts and high-touch areas.

The minimum thickness for vacuum casting is 0.75 mm, but for the best results, we recommend 1 mm to avoid shrinkage and wrapping. With thicker walls, you will get more support for your vacuum-casted parts.

Vacuum casting is an ideal process to create plastic and rubber parts for low-volume production, prototypes, and end-use parts. It’s best suited to design complex parts with intricate features and thin walls with accuracy and smooth surface finish.

During the vacuum casting process, we use mold clamps, vacuum pressure, and mold release agents to keep the mold together. For more complicated parts, our experts take additional measures, like bolts and screws.

At CreateProto, we use different materials for vacuum casting, from thermoplastics to resins to rubbers. It depends on the casting properties you desire for your product. For example, ABS or polycarbonate is used for durable and strong casting, while rubber is for flexible casting.
