KM Rapid provides vacuum casting (urethane casting) services for prototypes and small-batch parts. A silicone mold is made from a master pattern and used to reproduce parts in casting resin. Send your drawings, required quantity and finish requirements to discuss your project and request a quote.

Compared to traditional steel injection molds, this method significantly reduces tooling costs. The liquid material is injected into silicone molds under high or low pressure, resulting in parts with mechanical properties close to those of injection-molded components. A single silicone mold can typically withstand 15-20 production cycles, making it ideal for low-volume manufacturing.

Even parts with undercuts can be demolded smoothly due to the flexibility of silicone molds.

Silicone molds are inexpensive and quick to fabricate (short lead time).

This process is ideal for prototyping, small-batch production of new products, or replicating discontinued automotive components where original steel molds are unavailable.
