Slitting of Polyester Film Insulation for the Electrical Lighting Industry

W.S. Hampshire, Inc. has unmatched expertise for slitting and die cutting a wide range of tight-tolerance films. Our modern production facilities enable us to provide precision die cut products at high quantities and with short lead times. We supplied the polyester insulation film sheets shown here for a customer in the electrical lighting industry. With our automated Dusenbery 55″ slitter and rotary presses, we were able to manufacture these 205 mm in length, 29.2 mm in width, and 0.13 mm thick sheets with outstanding precision of + 0.076 mm/- 0.000 mm, and maintain that accuracy over a large, 2 million+ unit order.

Building quality right into the products we manufacture makes us a highly regarded supplier of electrically insulative film products. If you would like more information about this project, or how our services can benefit your next project, contact us today.
