How High-Quality Engine Cylinder Sleeves Are Made?

This video takes you inside a professional Cylinder Liner Factory, showcasing three key strengths of Cylinder Liner (Engine Cylinder Sleeve) manufacturing and quality control: 1.Factory Strength IATF 16949 certified, integrating centrifugal casting, heat treatment, and precision machining. Annual output exceeding 12 million pieces, serving global OEMs and the aftermarket. 2.Dimension Measurement High-precision CMMs, air gauges, and roundness testers perform 100% inspection on bore diameter, outer diameter, roundness, and cylindricity. Liner protrusion is measured using dedicated dial indicators, with standard range of 0.05-0.12mm. Critical dimensions controlled within ±0.01mm to ensure perfect fit with pistons and rings. 3.Quality Control Full-process quality control covers raw material analysis, molten metal rapid analysis, semi-finished metallographic inspection, and hardness testing. Finished products undergo liquid penetrant inspection, ultrasonic testing, and final acceptance. MES system ensures full data traceability, with samples from each batch retained for 300-hour durability validation.
