Custom Rubber Molding of Neoprene Ear Cushion for the Medical Industry

Considered to be the best in the industry, these custom molded MX41-AR ear cushions are manufactured using a hand-drawn design developed by Pierce-Roberts Rubber Company over 40 years ago. Beginning with this drawing and a customer-supplied 2D CAD drawing, and following strict OSHA standards, we first design and manufacture the appropriate mold. Next, we compression mold the ear cushions, and then bond the neoprene sponge to solid neoprene rubber, using water-based rubber glue. Available in black, blue, red, our ear cushions are tested by independent labs and visually inspected 100 percent at every stage of manufacturing.

Measuring 2 inches to ¾ of an inch in outside diameter, ¾ of an inch in inside diameter, and ¾ of an inch in thickness, each ear cushion weighs .11 of a pound. With a 1 to 2 week turnaround time, we ship orders to medical industry clients worldwide. To learn more, please contact Pierce-Roberts.
