Vacuum Casting

Description

Vacuum casting is a low-volume manufacturing process that uses silicone molds to produce high-quality plastic parts that closely resemble injection-molded components. Vacuum cast parts are produced by first creating a high-precision master pattern using 3D printing technologies such as SLA or SLS, which defines the exact geometry and surface finish of the final parts. This master pattern is then used to make a silicone mold, which is poured and cured around the pattern to capture every detail before the pattern is removed. Each silicone mold typically yields around 25–30 parts, depending on the part geometry, overall dimensions, and the chosen casting resin.
