Rapid prototyping (RP)

In plastic part design, technology has given us a variety of prototyping options. Rapid prototyping (RP) includes stereolithography, selective laser sintering, fused deposition modeling, laminated object manufacturing, and three dimensional printing. Each of these builds parts, one-by-one, from 3D-CAD models, joining layers of material to create the finished prototype. Rapid tooling (RT) uses rapid prototyping to create an initial part and then creates, from that part, a mold in which additional parts can be made. Mold materials can range from silicone rubber to composites. A third prototyping option is rapid injection molding (RIM), which works directly from a 3D-CAD model, using CNC machining to mill aluminum molds in which true injection-molded parts can be made. Finally, there is traditional injection molding, which is used primarily for production, but could conceivably be used to create prototypes.

SRG Global and its 400000 sq. ft. Morehead, KY facility, which specializes in conventional injection molding, painting, bright chrome finishing, and assembly, was featured on The History Channel’s “Modern Marvels: Chrome.” The program chronicled the history and production methods of chrome, and how the world has come to regard the gleaming product as an essential element for both decorative and practical use. The program told viewers about the complex electroplating process and how workers chrome plate plastic parts, a core capability of SRG Global. In highlighting America’s infatuation with chrome, the special also: — Showed viewers a 35000 square foot treasure trove of chrome at 4 State Trucks in Missouri — Took them on the road with some bikers to take a look at how Harley Davidson puts chrome to work both as a decorative surface and a protective covering on engine parts. — Visited a classic car gathering, where collectors showed off their sparkling tailfins and grilles, and in Michigan, perused a unique collection of more than 3000 chrome hood ornaments. — Explored the iconic, shimmering art deco dome of the Chrysler Building. — And, finally, a Colorado artist showed viewers how he rescues old chrome car bumpers from the scrap yard and transforms them into amazing chrome sculptures. About SRG Global SRG Global, a Guardian company, is one of the largest plastic trim manufacturers in the world. The company, formed when Guardian Automotive purchased Siegel-Robert
