Our RIM (Reaction Injection Molding) capabilities

JunYi's vacuum casting technology offers a wide variety of materials to facilitate the creation of cast urethane parts, typically for functional test, pre-production evaluation and low volume production. Cast urethane parts are quick and inexpensive without the need to invest any metal tooling when quantities are only dozens of short runs, and can be delivered within weeks in most instances.

Vacuum casting (also known as polyurethane casting) can be used to closely simulate final injection molded parts or finished products. Generally, molds are made from silicone rubber and use a CNC or SLA part as a master pattern. These molds duplicate details and textures and give consistent finishes from one part to the next. You can get production-like results including mechanical properties, colors, and finishes.

With 10 years' experience, JunYi's specialist team offers excellent vacuum casting service for low volume plastic prototypes, and helps you striking the right balance between high-quality, end-use parts and production lead-time. This translates into time and cost saving for customers seeking a competitive edge advance in form fit and function testing, pre-marketing, or even as low volume production alternative.
