Custom Injection Molded ABS Plastic Armrest for Riding Mowers

Making extensive use of our plastic injection molding capabilities, Northern Precision Plastics produced this plastic arm rest used on riding lawnmowers. Working from an ABS base material, our precision molding process kept tolerances of ±.003", and we ensured that the finished units each had less than .003" of flash. In addition to molding a piece with a complex shape and several gap features, the customer also required that the piece be free of burrs, pits, and sharp edges. In short, the arm rest needed to be ready for installation upon arrival at the client's facility.

The finished part measured 24.335" long by 10.77" wide, with a height of 5.662". For the finish we had the emblems pad printed white resulting in a very durable part for outdoor use. Our customer was pleased that we had exceeded expectations and accepted delivery of the completed order with full confidence.
