About C-K
Heritage In Engine Sealing
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.
Research & Innovation
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 advanced materials like Carbon-Carbon composites and cold spray technologies, lubricant systems, and custom tribological architectures.
Integrated Predictive Analytics Toolkit
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.
