Core Components

6 million parts a year — the benchmark for precision.

Our core business

Precision HVAC parts that drive the AC compressor

The AC compressor is the heart of automotive climate control. The precision parts that rotate and compress inside it are CY Autotech's core business.

Since 2006 we have volume-produced swash plates, hubs, shaft assemblies, rotor assemblies and center-head assemblies through an integrated process. From forged material to machining, heat treatment, assembly and inspection — all vertically integrated under one roof — we deliver micron-level dimensional stability with the economics of high-volume production.

Our parts run in Hyundai and Kia models for combustion vehicles and in Tesla and Ford models for eco-friendly vehicles, supplying 6 million+ parts a year at a defect rate within 100 ppm.

Product portfolio

Five core component families

We mass-produce the rotating and drive parts of the compressor on dedicated lines tuned to each component.

Swash Plate

Swash Plate

The angled plate that converts rotation into piston stroke. Flatness and surface quality directly drive compressor efficiency.

3.11M / year · since 2006
Hub

Hub

The rotating hub that transmits power. Shaft alignment and concentricity define vibration and noise performance.

1.66M / year · since 2012
Shaft Assembly

Shaft Assembly

The compressor drive-shaft sub-assembly. Precision machining of high-strength material and stable heat treatment are key.

780K / year · since 2014
Rotor Assembly (Eco)

Rotor Assembly (Eco)

Rotor assembly for electric compressors. A growth line aligned with the electrification of eco-friendly vehicles.

370K units / year · since 2011
Center-Head Assembly

Center-Head Assembly

The compressor's central head assembly, demanding precise multi-part assembly and reliable sealing performance.

370K units / year · since 2014

Volumes are representative production figures and may vary by model and year.

ASSEMBLY

From parts to assemblies

Precision-machined parts come together through assembly into finished units. The rotating group is assembled first, then combined with the housing and other parts into the final assembly.
