Choose Precision Tool Company for High Quality Plunger Rings

Our plunger rings are specifically designed and crafted to be used for hot chamber die casting and are available in an array of sizes. We make each ring from high performance ASL 42 stainless steel. By using this excellent grade of steel, our plunger rings provide strength, wear resistance, and reliability. We offer the highest quality rings in the industry.

Additional features of our outstanding plunger rings include:

  • Heat Treated for Durability – Each of our rings are heat treated in order to obtain a hardness of 45-52 Rc. This heat treatment process makes our rings tough and wear resistant.
  • High Grade Steel – We utilize a grade of stainless steel that is higher in carbon and chrome than type 420 stainless. This steel has molybdenum and vanadium added to it in order to provide a longer life than type 420.
  • Superior Design – All our rings are crafted from rolled flat wire, which is cut to order length and then formed. Doing this helps to enhance the circumferential properties of the ring. Additionally, this process yields a completely burr free ring with smooth edges.
