Our history

Built in Lansdale since the 1940s.

  1. 1945

    Three partners, one garage

    J. Howard Deming, Fred Zoller and Al Saddler, who had worked together during World War II making large babbitted bearings for ships, set up shop in an old 20×40 garage in Lansdale. The name comes from the wives and children of the three owners: three "Kris's," an equal share in the hope for the venture's success.

  2. 1948

    Outgrowing the garage

    Subcontract machining took off, and the company built the Walnut Street building it still operates from today.

  3. 1956

    16,000 square feet

    Two additions brought the facility to its current size. Conventional machinery was later joined by a growing fleet of CNC equipment.

  4. 1991

    A new generation

    After buying out his partners and running the company on his own, J. Howard Deming sold Tri-Kris to his Vice-President, William I. Carling, so the company would continue.

  5. 2006

    Family owned

    William I. Carling sold the company to his son, William E. Carling.

  6. Today

    Prototype to production

    Ten CNC lathes, ten CNC machining centers, 26 manual machines and a climate-controlled inspection lab, still on Walnut Street.
