“How German Engineers Keep 10-Year-Old Machines Running Like New”

The Ultimate Maintenance Guide for Fully Automatic Positive & Negative Pressure Machines: Maximize Lifespan of Your Second-hand Equipment

  Why Maintenance Matters More for Second-hand Machines
"A well-maintained 10-year-old machine outperforms a neglected new model."
For overseas buyers of refurbished plastic thermoforming equipment, proactive maintenance is your secret weapon to:
   Achieve 98%+ uptime comparable to new machines
   Reduce energy consumption by up to 25%
   Extend equipment lifespan beyond 15 years

Core Maintenance Checklist - Engineer Recommended

1,Daily Operator Tasks (5 Minutes/Day)

   Vacuum Pump Care
① Check oil level (Viewing port at 3/4 full)
② Monitor exhaust temperature (<85℃/185℉)
③ Listen for abnormal noises (Whining = bearing wear)

  Pressure System Check
① Test emergency stop response
② Verify pressure gauge stability (±0.1 bar)

 2,Weekly Technician Actions (30 Minutes/Week)
 

      Seal Integrity Test

①Apply soap solution to pipe connections → Check for bubbles

②Measure vacuum drop rate (<0.5 mbar/min when sealed)

     Lubrication Protocol

① Grease linear guides with Mobilith SHC 100 (High-temp resistant)
② Oil pneumatic cylinders per ISO 6431 standard

    Electrical Safety Inspection

①Tighten terminal connections (Torque: 1.2-1.5 Nm)
② Check ground resistance (<0.1Ω)

 3,Quarterly Deep Maintenance (4 Hours/Quarter)

System    Critical Procedure    Tool Required
Vacuum System    Replace oil mist filter + Rotor gap check    Feeler gauge (0.03-0.05mm)
PLC Controls    Backup programs + Clean heat sinks    Thermal camera
Hydraulic Unit    Change oil (ISO VG 46) + Flush lines    Particle counter (NAS 9)
Frame Alignment    Verify platen parallelism (<0.1mm/m)    Laser collimator

 Pro Tips for Refurbished Equipment Owners

 The 90-Day Reset Rule

» After acquiring second-hand machines:
‣ Flush vacuum pump oil 3 times (20-min runs between changes)
‣ Replace all pneumatic seals (Nitrile for <60℃/ Viton for >60℃)
Why? Removes debris from previous operation
