Holiday Shutdown Maintenance Guide | Building the Foundation for Efficient, Low-Carbon and Stable Production

Injection molding machine maintenance and shutdown care are critical for smart manufacturing operations, especially before long holiday shutdowns such as the Lunar New Year. At FCS, proper maintenance helps improve energy efficiency, extend machine service life, and reduce manufacturing carbon emissions.

Why Shutdown Maintenance Is a Key Part of Sustainable Manufacturing?

If equipment is not properly maintained before long-term shutdown, common risks may include:

• Oil degradation, increasing mechanical resistance
• Cooling water channel corrosion or blockage, reducing heat dissipation efficiency
• Electrical contact oxidation, increasing energy consumption and failure risk
• Material carbonization inside the barrel, increasing startup energy consumption and material waste
• Metal component corrosion, shortening equipment service life

Proper shutdown maintenance helps achieve:

✔ Reduced machine abnormalities and energy waste
✔ Extended full lifecycle service life of equipment
✔ Reduced equipment replacement frequency and manufacturing carbon emissions
✔ Stable production quality after restart with less material loss

🧰 Pre-Shutdown Maintenance — Ensuring Equipment Enters Optimal Standby Condition

•   Machine Cleaning and Surface Protection

• • Remove residual oil, plastic material residue, and dust
  • Apply anti-corrosion protection to metal surfaces
  • Clean and lubricate guide rails and sliding components

Proper cleaning prevents dust and oil buildup from becoming long-term wear sources and helps maintain machine efficiency.

• Lubrication and Mechanical System Inspection

• • Check lubrication piping integrity
  • Refill designated lubricants at all lubrication points
  • Inspect fastening bolts and moving mechanisms

Proper lubrication reduces operating resistance and energy consumption.

• Hydraulic System Inspection

• • Confirm oil condition and oil level
  • Clean or replace filters
  • Confirm no oil leakage

Healthy oil condition ensures hydraulic system efficiency and reduces energy loss.

• Electrical System Safety Inspection

• • Check power supply and grounding system
  • Clean dust inside electrical cabinet
  • Confirm cooling system is functioning properly

Stable electrical systems reduce abnormal energy consumption and equipment risks.

🔒 Shutdown Operation — Reducing Equipment Aging and Energy Loss

•   Injection Unit

• • Perform barrel purging and remove all residual material
  • Prevent oxidation or carbonization inside barrel

• Mold and Clamping Mechanism

• • For long shutdown periods, mold removal or anti-corrosion treatment is recommended
  • Avoid high-pressure clamping during shutdown

• Cooling System

• • Drain all cooling water channels
  • Prevent scaling or corrosion that reduces heat dissipation efficiency

• Power Management

• • Turn off main machine power supply
  • Clearly label shutdown status

🛡 Long-Term Shutdown Environment Management — Slowing Equipment Degradation

 Recommended storage conditions:

• Dry and well-ventilated environment
• Dust-proof and moisture-proof protection
• Stable temperature and humidity conditions

Proper storage significantly reduces material degradation speed of equipment components.

🔍 Pre-Startup Inspection — Reducing Startup Energy Consumption and Failure Risk

  Recommended checks before restarting production:

✔ Oil level and oil temperature status
✔ Lubrication system operation
✔ Electrical connection stability
✔ Cooling water system condition
✔ Low-speed test run to confirm mechanical condition

Avoid injection and plasticizing operations before reaching operating temperature.

Moving from Equipment Maintenance Toward Smart Sustainable Manufacturing

Under the trend of smart manufacturing, equipment management is evolving toward:

• Preventive maintenance management
• Operational data monitoring
• Equipment life prediction
• Energy efficiency optimization

Proper maintenance strategy reduces unnecessary energy consumption and equipment replacement needs, forming an essential foundation for sustainable manufacturing.
