Plastic Injection Molded Component for Window Shade Assembly Sample Project

injection_molding_household_large-optimized sample

Stelray Plastic Products, Inc. produced this end housing that is used on a pin, in a power window

shade assembly for a home interior industry client. We provided the plastic injection molding of the

polycarbonate end housing and inserted the bronze bushing into the housing while the material

was still expanded from the heat. We knew that the interior diameter of the bushing was a critical

dimension for quality control because it was the key to a proper fit. The part measured 4.5″ long with an outside diameter of 2.000″. It took us eight weeks to do the tooling and 2 to 3 weeks to produce each 1,000 unit

run for delivery to Connecticut and California. To learn more about this plastic injection sample project,
