Reaction injection molding - RIM molding involves some pressure that can place on the molds during part injection and press opening.
For thermosets, three processes are described: reaction injection molding, pultrusion, and compression molding.
This manufacturer of reaction injection molding equipment is offering up to a $5,000 credit for a limited time when an end user trades in its non Gusmer-Decker mixhead on a new Gusmer-Decker mixhead.
The thermoformed films can subsequently be reinforced by injection molding with thermoplastics or by reaction injection molding (RIM) with polyurethanes.
Huntsman Polyurethanes offers advanced automotive systems for Structural Reaction Injection Molding (SRIM) of polyurethane.
Reaction injection molding is faster than the previous casting process, and allows the processors to mold in bright colors, eliminating the need for painting.
Fortunately, in what is being billed as the first application of its kind, Caterpillar is utilizing a reinforced structural foam polyurethane reaction injection molding (RIM) system from Bayer Corp.
Reaction injection molding (RIM) is carried out by polymerizing very reactive monomers and oligomers in the mold [1].
The DC/DS technology combines conventional thermoplastic injection molding with reaction injection molding (RIM) in a single tool - delivering a hard polycarbonate blend substrate with an ultraviolet-stabilized, scratch- and chemical-resistant polyurethane coating or aliphatic polyurethane self-skinning foam.
Named "clearmelt," it combines thermoplastic injection molding and thermoset polyurethane (PUR) reaction injection molding to produce parts like interior trim pieces.
Engel North America has introduced clearmelt, describing it as "a high-volume manufacturing system that combines both thermoplastic injection molding and thermoset polyurethane (PUR) reaction injection molding, with innovative mold design and dedicated automation to efficiently and economically produce scratch-proof, attractive, clear-coated components, such as finished automotive interior trim." Unlike more conventional spray-coating and varnishing methods, Engel says, clearmelt reduces finishing requirements, while also reducing the cost of labor, materials, and waste disposal.
