We manufacture rings in a diameter range of 0.5" to 70" in various widths and radial wall combinations. We stock rings of many configurations for fast delivery. Rings are available in several Joint Designs and Materials. We also provide Application Assistance in ring usage and design. Several coatings can be applied to improve the function of the ring in various environments.

Accu-Seal Machine |
Most of our rings are manufactured using our Accu-Seal process. Accu-Seal is a CNC cam free non-round machining process that produces the outside diameter, inside diameter and the ring width. Ring features such as chamfers, corner radii and OD profiles like taper faces, barrel faces and grooves can be easily added. This process assures a high degree of circularity and perperdicularity between the diameters and the ring sides. Varying the amount the ring is turned out of round will control the ring's tension and free state diameter.

These rings are especially designed and engineered for zinc die casting machines. They are made from Grade 420 stainless steel which provides the ultimate in strength, hardness, and resistance to heat and corrosion. Its low coefficient of friction makes it compatible with its mating parts in die cast machines. |

These rings are made to our exacting specifications in size, shape and hardness providing a consistent compression load on sleeves and goosenecks which reduces there replacement. Our rings are heat treated to Rc 48-55 hardness and ground to final size. They can last up to ten times longer than rings made from cast iron alloys improving production efficiency, reducing machine down time and providing consistent quality of die cast products.
Rings are supplied ready for installation. Plunger groove widths should be .010” over the maximum ring width. If plunger groove is deteriorated from use, it can be re-cut an additional .030” wide and still accept standard width rings. Our standard rings have step cut joints but butt cut and angle cut rings can be supplied. See chart on the next page for standard and stocked ring sizes.
