RIM (Reaction Injection Molding), is a Rapid Tooling process where parts are made from mixing and injecting PU materials into a mold and cured through a process of polymerization (molecular cross-linking) in a low pressure / room temperature environment. Because of KAIAO's High Efficiency, Short Cycle, Low Cost Production Runs, we can offer the best RIM processing solutions & assure fast deliveries worldwide.

We always strive to improve our products & services and to meet the exact requirements of our clients. Success at KAIAO is driven by our professional RIM techniques & close cooperation with material suppliers. Through the use of our applied techniques & innovative materials, we offer highly customized PU products.

Compared to Plastic Injection Molding, RIM (Reaction Injection Molding) is a more simple and convenient process with a shorter production cycle. Compared to Vacuum Casting, RIM offers a higher level of automation and efficiency. Compared to Thermo-Forming and Board Bonding, RIM is a more flexible design option. RIM parts can be designed with elaborate surface details and Class A surfaces, with integrated structures and different wall thicknesses, and with machining stability and accuracy.

When making RIM molds, clients can choose to use low cost casting materials. Using ABS, Epoxy, and Aluminum mold making materials, KAIAO can make molds of all sizes for all kinds of applications. Our RIM Technicians provide professional technical suggestions and the best solutions in accordance with each client's specific project requirements. At KAIAO, RIM Mold Design and Mold Making services can be completed within 2 weeks or less.

With our experience in mold design, mold making, controlling precision processes, and using quality materials, KAIAO can make large RIM parts with 3 to 6 mm wall thicknesses that have High Rigidity and High Strength. Even though the walls are only 3 to 6 mm thick, the edge of the material is rigid and strong enough to provide excellent stability.

KAIAO can provide clients customized PU products for both design and function. Our RIM materials are economical and ideal, offering designers endless design possibilities and obtainable solutions.
