Capabilities · Plastic Injection

Precision plastic parts,engineered to spec.

Scientific moulding, not trial and error.

Sliders, cable drums and guides decide how smoothly and quietly a window regulator works. Han Yale’s Taiwan engineering team defines every moulded component — part design, material, mould specification and process window — and validates it with mould-flow simulation and scientific moulding, while production data is analysed with Ca, Cp and Cpk for continuous improvement.

Window Regulator Plastic Injection

Small parts. Critical performance.

Plastic components guide the glass, carry the cable and transfer motor torque — their dimensions decide how smoothly and quietly a regulator works.

Advanced Machines and Moulds
01Engineering

Mould and Process Definition

Every moulded part starts in Taiwan. Our engineers define the part geometry and material, design the mould in-house and run mould-flow simulation before any steel is cut. The moulds are built to Han Yale designs and remain Han Yale property — qualified against each part’s critical dimensions and placed with our production sites on loan — so the tooling, the specification and the process window all stay under Han Yale control, wherever the part is moulded.

Components and Quality

Components and Quality

Sliders, cable drums, guides and glass clips are specified and released by Han Yale’s Taiwan R&D, then produced on Han Yale-designed and -owned moulds under the same controls at our Vietnam facility and qualified moulding partners. Incoming and in-process inspection check every critical dimension against the drawing before a part reaches regulator assembly.

Production data is collected and entered into the system for Ca, Cp and Cpk analysis — reflecting our commitment to continuous improvement.

Scientific Production
03Scientific

Scientific Production

Rather than relying on trial and error, Han Yale uses a scientific approach to find the optimal set of production parameters. Moulding conditions such as temperature, pressure, injection speed and cooling time are studied, locked in and released as the process window every production source must follow — leading to significant gains in product quality and production efficiency.

  • Mould-flow simulation during design
  • Structured parameter studies to define the process window
  • Locked, documented process settings that every production source must follow
Data-Driven Control

Every dimension measured. Every trend analysed.

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.

Ca

Accuracy

Measures how far the process centre sits from the specification target — a quick check that the process is aimed correctly.

Cp

Precision

Compares the specification width with the natural spread of the process, showing how tightly it is able to repeat.

Cpk

Capability

Combines centring and spread into one index. Automotive programs commonly use 1.33 or higher as the benchmark for a capable process.

PDCA

Continuous Improvement

Results drive corrective actions, parameter updates and preventive maintenance in a closed improvement loop.

Engineered in Taiwan. Manufactured in Vietnam.

One controlled production chain.

From tooling to final inspection, every major process for HANSUN window regulators is defined and controlled by Han Yale — specified by our Taiwan engineering team and produced on Han Yale-designed, Han Yale-owned tooling at our Vietnam facility and qualified partners — so quality data flows from one station to the next.
