Plastic Injection Molded Component for Window Shade Assembly Sample Project


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,

Customer Testimonial

★ ★ ★ ★ ★  We were referred to Stelray Plastics by our packaging agency to help us create a unique new product that we wanted to launch in the US in six months. We has only a concept and no design or engineering figured out, nor did we have any idea how to move forward. Stelray helped us turn the concept into functional industrial design and provides us with their expertise from a process standpoint and we had our production molds in place in time to make our launch date.  They provides us with professional guidance from start to finish which resulted in a great finished product that was competitively priced and under budget. We would highly recommend Stelray Plastics to anyone looking for a valuable partner that can deliver turn-key, high quality injection molded products. They are extremely knowledgeable, professional and great to work with.      —- Jim Smith

Customer Testimonial

★ ★ ★ ★ ★  I first came across Stelray Plastics with a new product design that our client molder at the time and several molders told us was not possible to accomplish. We worked with the Stelray engineering team to perfect the design and in a few short months we were making what we were told couldn’t be done.  Staying ahead for the competition is imperative, so staying with a supplier that wasn’t  able to think outside the box wasn’t an option for us.  We quickly realized we were with the wrong molder and moved all of our molds to Stelray. I highly recommend Stelray Plastics for both new designs and current molding jobs. They really step above the competition. We have cutting edge designs and needed a partner with the technology and vision to make it a reality. Stelray plastics was that supplier from the beginning to the end.   –Scott Crysler
