Molded Three Ring Bonded Nitrile Bumper

When Pierce-Roberts Rubber Company was contracted by a client in the automotive industry to custom manufacture this Nitrile bumper for a Twin Otter aircraft application, we rose to the challenge. Adhering to specifications laid out in a client-supplied 3D Solidworks drawing, we designed and manufactured the necessary mold. We then manufactured three metal rings, an inner, outer, and middle ring, which were then transfer molded into the rubber. We worked with Nitrile and 4130 aircraft-quality steel, conducting several in-process and destructive tests, to ensure the middle ring was properly suspended inside the rubber. The entire process was designed to be constantly repeated while achieving the same high level of quality.
