From Lightweighting to Low-Carbon: Link Upon’s Path to Sustainable Manufacturing

In May 2024, we shared insights on “Link Upon Engineering Plastic Screws range from lightweight to low carbon footprint“, with World-class competitiveness.”, highlighting trends in reducing industrial component weight and carbon emissions. Today, we’re excited to share the practical energy-saving actions we’ve already implemented — spanning from advanced equipment to employee-driven initiatives.

Smarter Machines, Smarter Energy

•→CNC Upgrades: Replacing outdated machines with smart standby systems and inverter controls cuts idle waste.
　→ Annual savings: 36–41% per unit; plant-wide 5–8%.

•→Injection Molding Systems: Adopting all-electric, servo-hydraulic, and hybrid machines optimizes efficiency while meeting production demands.
　→ 69–75% less power vs. hydraulic systems; 3–6% plant-wide savings.

Facility-Wide Efficiency

•→Air Compressors: Switching to variable-speed rotary units plus centralized management.
　→ 24–30% less power.

• •→Lighting & Inverter air conditioner: High-efficiency LEDs and inverter AC systems.
  　→ Lighting saves 43–47%; Air conditioner saves ~17%.

Digital Monitoring & People Power

Smart meters now track real-time energy data, driving continuous optimization. Combined with staff training, this adds another 2–3% savings and builds a lasting energy-conscious culture.

The Results

•→Total energy savings: ~20%
•→CO₂ reduction: 55–60 tons annually
•→Link Upon 2024 total emissions: 419 tons
