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 Amber’s high efficiency,short cycles,low cost production runs,we can offer the best RIM processing solutions & assure fast deliveries worldwide.

Compared to Plastic Injection Molding,RIM 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.
With our experience in mold（ABS mold,Resin mold,Aluminum mold) design and mold making,controlling precision processes,and using quality meterials , Amber can make large RIM parts with 3 to 6 mm big and thin walled partsthat 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.
A cost effective and fast alternative to injection molding, RIM is the perfect choice for low volumes and many other projects. RIM offers
• Low tooling costs
• Complete design freedom
• High strength to weight ratio
• Elimination of secondary operations
• No sink marks
• Low weight
• Wide range of physical properties
