RIM Question What is RIM? How is RIM different from traditional injection molding? How many kinds of RIM are there? What are the major RIM materials? Is my part right for RIM? What RIM finishes are available?

Is my part right for RIM? By Size? RIM is ideal for large parts. Generally speaking, Rimnetics can mold a part 38"x60"x20" and weigh 100 lbs. By production quantities. Annual quantities of a few hundred to four or five thousand generally fit the RIM method. Part design features, together with tool cost amortization issues come into play. The easy way to settle the quantity question is to RFQ the part and compare. By structural design needs. RIM, with its unique molding abilities, is often employed to unitize design, reducing part count. Designers use RIM to avoid the dreaded "thermoplastic sink" that occurs when there's a mix of wall thicknesses caused by the called for thick ribs for structure. By structural property needs. For high stressed parts, RIM offers tough polyurethane formulations. Such formulations may be further enhanced through fillers, metal encapsulation or a SRIM composite. RIM provides the designer with the advantage of combining the efficiency of a molding with the advances in polymer chemistry.       © 2008 Rimnetics, Inc.   Mountain View & Loomis, California | Rimnetics is ISO 9001:2000 Certified
