Production Line Design

GEOSUN’s production lines are designed based on a "U-shaped" layout, featuring:

• Unified workflow direction to enhance efficiency

• Minimized equipment spacing to save space and reduce movement

• Streamlined material logistics following the principle of
  “Single piece (small batch), one-process transfer”

• Just-in-time material supply, based on:
  “High frequency, low batch volume”

In terms of workforce operations, we adopt a “multi-process per person” principle:

• Each operator is responsible for multiple sequential processes

• Clear task ownership and direct internal communication

• Strong employee engagement and a heightened sense of responsibility
  → Ensures greater product quality and operational transparency
