Reaction injection molding is an excellent alternative DH offered for low volume production of plastic parts,car bumpers electronic enclosures and panels for medical device,sound box and etc with below features.

•    Lower your tool costs
•    Complete design freedom
•    Higher strength to weight ratio
•    Improve or eliminate secondary operations
•    No sink marks
•    Lower weight
•    Wide range of physical properties

In addition to high strength and low weight, polyurethane Reaction Injection Molding (RIM) parts exhibit heat resistance, thermal insulation, dimensional stability, and a high level of dynamic properties. They also offer resistance to inorganic and organic acids as well as many other potentially damaging materials and chemicals including a large number of solvents. Resistance to weathering and aging is another plus, though extended exposure to the sun’s ultraviolet rays typically results in a color shift at the surface. Low processing temperatures (95F to 150F) and low injection pressures (30 to 100 psi) make the Reaction Injection Molding (RIM) process more economical than other molding methods for large parts.

In general, it uses considerably less energy to make the same product injection molded thermoplastics and requires less equipment and floor space. It’s also more automated than other thermoset molding alternatives. No energy consuming remelting of a solid thermoplastic is necessary, and the cycle times of the Reaction Injection Molding (RIM) process are competitive with thermoplastic injection molding of similar sized parts.

Polyurethane resins for RIM have grown into a broad range of formulations with particular physical properties for specific performance requirements. Parts can be supplied primed, painted or surface treated with graphics to simulate various textures
