Detailed Description
The urethane casting process frequently begins with a stereo lithography (SLA) rapid prototype master pattern. Machined and/or fabricated master patterns can also be used. The SLA RP model is inspected for accuracy then the “appearance” surfaces are bead blasted, sanded smooth, then a primer coat is applied to achieve the surface finish required to meet your application requirements. If the urethane parts are to be polished or cast in clear resin then the surface will be polished to a gloss finish in preparation to making the SRM (silicone rubber mold). Next the SRM is created. The silicone rubber uses a room temperature vulcanization process typically referred to as RTV. Your part is carefully scrutinized by one of our technicians to determine the best molding setup to achieve the highest quality urethane casting reproduction. Parting lines are selected to assure best location thus avoiding flash on appearance surfaces. Rubber mold runners, gates, sprues and vents are located in areas to optimize mold fill, isolate and minimize air bubbles to non-critical areas, and optimize appearance surface quality.
