Urethane castings can be an outstanding alternative to injection molding for low to medium volume production of high-quality plastic parts. ProTek Models is your one stop supplier for all of your cast urethane projects. With our talented staff, state-of-the-art machinery, and high quality materials, there is almost no urethane casting project we can’t handle.
Urethane castings are production quality, end-use, rigid or flexible plastic parts. The process begins with the customers provided CAD models being reviewed by ProTek Models skilled engineering team evaluating the CAD model for any issues. The customer specifies the material properties and ProTek Models selects the best material that meets the specifications. Then a master part/ pattern is 3D printed and finished to the end-use part finish with anything from glassy smooth to leather and textile finishes. A silicone (RTV) mold is then created for casting of the parts. ProTek Models highly skilled tool makers can produce molds for simple and extremely complex parts up to 8’ x 4’ x 4’ (yes feet not inches). This process produces very high-quality plastic parts that is suitable for quantities from one to hundreds. The finished dimensions of urethane cast parts depend on the material used and the part geometry.
ProTek Models has combined over 60 years of experience making patterns, silicone molds, and casting. The entire process is done 100 percent in-house. We print the master parts/patterns, sand and finish them, make the molds, cast them, and inspect them. While some of our parts are still hand poured, we primarily utilize two production grade MCP vacuum casting machines for parts with extremely fine details and challenging geometries. We also utilize pneumatic injection guns that prevent the introduction of air in to the material during the injection process. These processes produce parts that are virtually bubble free. our experienced team creates repeatable, high-quality parts that are free of air bubbles and surface imperfections. Our urethane cast parts are in many cases indistinguishable from injection molded parts with the similar strength and durability properties. We can cast in dozens of different materials and in numerous different colors including water clear. We also offer part finishing and painting services for any parts requiring this service.
