Vacuum Casting Service
with Mastars
Injection-molded quality and finish, without the associated costs or lead times.
Vacuum Casting Service
Vacuum casting produces production-grade rigid, flexible, and rubber parts using 3D-printed master patterns and silicone moulds, enabling short-run manufacturing of parts up to 2300 mm long. Finished part dimensions depend on master model accuracy, geometry, and casting material.
Ideal for parts requiring color, surface quality, and toughness, vacuum casting serves as a low-volume alternative to insert moulding, supports diverse materials, and acts as bridge tooling between 3D printing and injection moulding (balancing quality, cost, and time). Parts can also be clear, color-matched, painted, or fitted with inserts.

As cast
As-cast parts preserve the natural surface texture and appearance of the casting mold.
Final result:
Matte or grainy surface
May feature minor imperfections and irregularities
Metallisation
Mirror polishing
Smooth
Smooth finishes come from polishing/grinding the master model to erase 3D printing/CNC marks and imperfections, delivering a uniform, blemish-free surface.
