Heat Vulcanizing of a Rubber O-Ring for the Military Industry

At Quick Cut Gasket & Rubber Corporation, we manufacture high quality O-rings for commercial and industrial purposes. Our years of experience, combined with a state-of-the-art manufacturing processes, allows us to deliver a better rubber O-ring product, made to match your application requirements exactly. In the project highlighted here, this ability to answer to highly customized applications came through for a military-industry customer.

The customer, a manufacturer of land mine detectors, came to us for our ability to manufacture high-precision O-rings completely in-house and under short lead times. They required a 12.5″ inner diameter, 0.070″ thick O-ring made to specific application standards requiring tight tolerances, exceptional durability, and long life in hazardous weather conditions. Our advanced manufacturing process, which places an emphasis on testing and evaluation, was able to exceed these tough requirements.

We elected to use a clamshell heat vulcanizer for primary fabrication of the O-ring out of silicone. This combined approach would allow for reliable, fast fabrication without a high error rate. First article, in process, and final product testing were employed during the manufacturing process. Tightest tolerances reached +/- .04″ – .05″.

Upon delivery, the customer was completely satisfied with our mission-critical silicone O-rings. Despite the thousands of examples we delivered, not one was rejected for quality issues.
