Driven by a lifelong commitment to engineering excellence, Harold E. McCormick, PE, founded the business to explore and pioneer advanced methods of piston ring modeling and optimization. Originally established as C-K Engineering, Inc., the firm evolved into C-K Technologies, LLC in 2008 to deeply pursue cutting-edge innovation in piston ring design and simulation.
Under Harold's technical leadership, the company has leveraged decades of specialized expertise to develop industry-standard solutions—such as the proprietary PROMPT cylinder kit modeling system—helping engine manufacturers and research teams solve complex compression and spark-ignition sealing challenges worldwide.
C-K Technologies, LLC, based in Ellisville, MO, specializes in piston design, cylinder kits, and precision measuring. The firm translates complex dimensional engineering into predictable sealing performance and reduced program risk. This expertise spans across both conventional and experimental spark-ignition (SI) and compression-ignition (CI) engines.
The engineering team treats sealing technologies as a distinct, highly specialized discipline. Operating actively within Small Business Innovation Research (SBIR) programs, the company serves as both a prime contractor and subcontractor. This research focus drives continuous advancement in materials, lubricant systems, and custom tribological architectures.
Analytical operations leverage the proprietary PROMPT software model, SEE 3D surface analyzer, and BEE 3D bore geometry gage. PROMPT quantifies blowby and assesses oil control, SEE 3D characterizes 30+ surface parameters, and BEE 3D measures distortion within two microns. This interconnected toolkit provides engine programs with fully traceable data and decision-ready guidance.
