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 ...

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.

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 ...

Lightweight parts, energy-saving processing or combining several process steps into one. It can all be summarized under one buzzword: sustainability. A technology that is highly promising is ...

A moldmaker said recently that it sometimes takes him up to eight months to validate a large, high-cavity medical mold. Maybe this surprises you, but it doesn’t surprise many OEMs in the medical and ...

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 ...
