Urethane Vacuum Casting
Urethane Vacuum Casting is a highly versatile technology capable of producing parts in a range of polyurethane (PU) resins and cast nylon, to replicate and replace engineering polymers for prototypes and low-volume production.Using two-component polyurethanes and silicone molds, Vacuum Casting is known for its fast production of high-quality prototypes or end-use products.The cast parts can be produced in a broad range of surface finishes and various colors.

How Does Vacuum Casting Work?

Vacuum Casting begins by producing a master model, typically via 3D printing or CNC from CAD digital model, with a high-quality surface finish. Then a silicone mold is produced by casting silicone around the master copy, partially under vacuum to avoid air bubbles. After curing, the silicone mold is cut according to pre-defined parting planes and the master is removed, leaving a cavity to make copies.

Why choose Vacuum Casting?
Silicone molding results in high-quality parts comparable to injection-molded components. This makes vacuum casted models especially suitable for fit and function testing, marketing purposes or a series of final parts in limited quantities. Vacuum Casting also lends itself well to a variety of finishing degrees, and we can match the finish you need for your parts.
Ideal applications for Vacuum Casting:
Short run production,Pre-launch product testing 、Small series of housings and covers 、Concept models and prototypes 、Fast and cost-effective low-volume production series
