Quality at every stage, from material to shipment.
At Han Yale, the commitment to quality is evident at every stage of manufacturing — from incoming material control to final assembly. Data is collected throughout the process and analysed with tools such as Ca, Cp and Cpk, so continuous improvement is built into how we work.
Quality is not added at the end of the line — it is controlled at every hand-off between processes.
Han Yale is dedicated to delivering the highest-quality products and services, and this is reflected in a rigorous approach to quality assurance. From data collection to detailed Ca, Cp and Cpk analysis, a continuous improvement methodology ensures our products are of the highest quality.
This commitment extends to every part of the company’s operations and is core to our mission of providing customers with the best possible products and services.
A structured inspection flow — standard practice under the IATF 16949 automotive quality system — keeps nonconforming parts from moving to the next step.
Raw materials and purchased parts are inspected before they enter production.
Critical dimensions are checked at each process, including optical measurement of cable assemblies.
100% online inspection at final assembly, with sampled verification on real vehicle doors.
Packing, labelling and shipment checks before products leave the factory.
Production data from each station is fed into Han Yale’s system for statistical process control, so drift is caught before it becomes a defect.
Measures how far the process centre sits from the specification target — a quick check that the process is aimed correctly.
Compares the specification width with the natural spread of the process, showing how tightly it is able to repeat.
Combines centring and spread into one index. Automotive programs commonly use 1.33 or higher as the benchmark for a capable process.
Results drive corrective actions, parameter updates and preventive maintenance in a closed improvement loop.
From tooling in Taiwan to final inspection at our Vietnam factory, every major process for HANSUN window regulators is controlled by Han Yale — so quality data flows from one station to the next.
