Vacuum Casting Products

Vacuum Casting Process

Master Model Building

Precision prototypes are produced using 3D printing or CNC machining. Each master model is meticulously post-processed to achieve specified surface finish requirements.

Silicone Mold Making

Vacuum-cast silicone ensures bubble-free molds with intricate details. The master model is suspended within a mold frame, and liquid silicone is poured under vacuum conditions.

Parts Production

Following cure, the mold is opened and the part is demolded. Post-processing operations (trimming, sanding, painting) are carried out to achieve the final prototype specifications.
