Total control from raw material to finished part.
Han Yale’s in-house stamping process at our Vietnam factory provides total quality control from raw material to finished parts. As an IATF 16949 certified manufacturer, we rely on standardised procedures and continuous improvement — with skilled technicians, regularly maintained and calibrated presses, and carefully inspected raw materials from trusted suppliers.
Rails, brackets and base plates carry the load of the glass every day — they are stamped in-house at our Vietnam factory to tight tolerances.
Advanced stamping machines are operated by skilled technicians and are regularly maintained and calibrated to keep them performing at their best. High-quality raw materials from trusted suppliers are inspected before use in production.
By controlling every aspect of production — from initial design to final inspection — Han Yale delivers parts that meet or exceed customer expectations.
The stamping department is equipped with presses ranging from 50 tons to 500 tons, enabling stamped parts of varying sizes and complexity — from small components to larger, more complex rails and brackets.
All major stamped components are manufactured in-house at our Vietnam factory, so the dimensions and specifications of each part meet Han Yale’s premium standard.
Production data is systematically entered for Ca, Cp and Cpk analysis, helping us quickly identify areas for improvement and implement changes that raise quality and efficiency.
Automated stamping lines improve production efficiency and product stability. Automation reduces handling variation, keeps cycle times consistent and supports stable quality across high-volume runs.
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.
