Splicing and Vulcanizing
Vulcanizing is essentially welding with rubber. It is a great alternative to injection molding for smaller runs of O-rings, up to a few thousand parts. After the material is cut to length (most often cord or tubing), a liquid rubber adhesive is applied to either end and allowed to cure. Then, the joint is fit into a press at temperatures up to 500° F. The combination of heat and pressure weld the two ends together, creating a bond that is as strong, if not stronger, than the parent material. With 30 standard presses, 4 NorMec machines (for sponge rubber), and over 30 years of experience, Phoenix Associates is well-equipped to handle any of your splicing needs. We commonly work with Mil-Spec materials from top extruders and have vulcanized some very unusual profiles. From basic manway and tubeless tire seals to gaskets for shipping explosive ordinance, our repertoire speaks for itself.
