Reaction-injection molding has become a premier polyurethanemolding process that offers automotive engineers versatility in the materials used to produce high-quality, highly styled parts.

Reaction-injection molding (RIM) combines two lowviscosity liquid streams consisting of a reaction catalyst and initiators (containing mostly monomer) inside the mold. The resultant polymer grows in ...

Established in 1982, Romeo RIM Inc. (Romeo, MI, US) commands >70% of the North American market for energy-absorbing bumpers on vehicles such as transit buses, airport shuttles and light trucks, made ...

Polyurethane resin systems (PURs) offer a host of inherent processing and performance properties that could be advantageous to automakers. Cured PURs exhibit greater stiffness at lower weight than ...

Secondary finishing is dramatically reduced in an interesting new injection molding process out of Germany called “DirectSkinning”. The new technology combines injection molding of thermoplastics with ...

Drying of plastic resin can be a key step in the injection molding process, since too much moisture can cause a number of processing problems. Most polymers exhibit at least some level of polarity and ...
