Preventive Maintenance Scheduling

If you're the Head of Maintenance in an asset-intensive operation and want to structurally reduce breakdowns, here’s where to start (for operations using SAP). Emergency work isn’t usually an equipment problem. It’s a system discipline problem. Here are 10 things that must be fixed. 1. Notification Discipline Every failure must start with a SAP notification with the correct: • Functional location • Equipment • Failure code • Cause code • Description No notification = no data = no reliability improvement. 2. Follow the Workflow The correct process exists for a reason: Notification → Planning → Work Order → Scheduling → Execution → Confirmation → History Skipping planning leads to longer downtime and repeat failures. 3. Build Proper Failure Codes Most SAP systems lack structured failure libraries. Create clear codes for mechanical, electrical, instrumentation and process failures. Then run monthly Pareto analysis. 20% of failure modes cause ~80% of breakdowns. 4. Kill the “Hero Maintenance” Culture Organizations often reward technicians who fix things fast. World-class maintenance rewards preventing failures. Focus on MTBF improvement, not firefighting. 5. Increase Planned Work Breakdown-heavy sites often operate like this: • 50% breakdown work • 30% reactive • 20% planned Target: • 70–80% planned work • <10% emergency work 6. Use Preventive Maintenance Properly Many PM tasks are outdated or copied from OEM manuals. Move toward condition-based maintenance where possible: • Vibration monitoring • Oil analysis • Thermography • Ultrasonics 7. Build Reliability Engineering Without reliability engineers, maintenance stays reactive. Their job: • Root cause analysis • Bad actor identification • Strategy reviews • Failure elimination 8. Eliminate Bad Actors In every plant: 10 assets cause ~50% of downtime. Use SAP history to identify and permanently fix them. 9. Fix Spare Parts Strategy Breakdowns escalate when parts aren't available. Your spare strategy must include: • Critical spares lists • Minimum stock levels • Lead time control 10. Track the Right KPIs Focus on: • Planned Work % • Schedule compliance • MTBF • MTTR • Emergency work % If emergency work exceeds ~15%, the system needs fixing. Breakdown-heavy operations rarely have a technician problem. They have a system problem. Fix the system → breakdowns drop. 🔹🔹🔹🔹🔹🔹🔹🔹🔹🔹🔹🔹🔹🔹 I’m Allan Inapi.

Total Productive Maintenance (TPM) is a comprehensive approach to equipment maintenance that aims to achieve perfect production: zero breakdowns, zero defects, and zero accidents. It integrates maintenance into the daily operations of all employees, from operators to managers, to maximize equipment effectiveness and promote a culture of ownership. The Pillars of TPM: TPM is built on 8 pillars, each focused on proactive and preventive maintenance to enhance operational efficiency: Autonomous Maintenance (Jishu Hozen): Operators take ownership of routine maintenance (cleaning, inspection, lubrication). Empowers operators and reduces dependency on maintenance teams. Planned Maintenance: Scheduled preventive maintenance based on failure data and lifecycle analysis. Reduces unplanned downtime and extends equipment life. Quality Maintenance: Uses root cause analysis and preventive tools to eliminate defects caused by equipment. Focuses on maintaining conditions that assure quality output. Focused Improvement (Kobetsu Kaizen): Cross-functional teams tackle chronic problems and inefficiencies through structured problem-solving. Drives small, incremental improvements in performance. Early Equipment Management: Involves maintenance and production input during equipment design or procurement to improve maintainability, safety, and ease of operation. Education and Training: Develops skills across all levels to ensure correct operation, maintenance, and continuous improvement knowledge. Safety, Health, and Environment: Ensures machines and processes are safe and environmentally friendly. Aims for a zero-accident workplace. TPM in Administrative Functions: Applies TPM principles to office and support areas, optimizing workflows, information flow and efficiency. Benefits of TPM: Fewer breakdowns and unplanned stoppages Higher equipment uptime and productivity Improved product quality Reduced safety incidents Increased employee engagement and accountability Lower total maintenance costs Real-World Example: Context: A bottling plant suffered from frequent filler machine breakdowns, causing lost time and overworked maintenance teams. TPM Applied: Operators were trained to clean and inspect the machine daily (Autonomous Maintenance). Maintenance scheduled a monthly deep inspection (Planned Maintenance). The cross-functional team did a root cause analysis of breakdowns (Focused Improvement). Operator logs and visual indicators were introduced (Education/Training). Result: Breakdowns dropped by 70%, and the plant’s OEE rose from 65% to 85% within six months.

Injection molding preventive maintenance is a proactive approach to maintaining injection molds and machines, aiming to prevent unexpected failures and ensure consistent part quality. This involves regular cleaning, inspection, and lubrication of critical components, both for the mold itself and the injection molding machine. Frequency varies, but it's generally recommended to perform basic maintenance before and after each production cycle, with more in-depth checks and maintenance at specific intervals based on cycles or time. 1. Frequency: Daily/Before & After Each Cycle: Clean mold cavities and runners, check for debris, and ensure proper lubrication of moving parts. Weekly/Every 20,000 Cycles: Inspect for wear and tear on key components like nozzles, screws, and mold clamps, and replace any worn parts. Monthly/Every 100,000 Cycles: More in-depth inspection of clamp components (bushings, sensors, etc.), check clamp parallelism, and inspect heater bands for proper function. Annually/Every 250,000 Cycles: Perform a comprehensive checkup of the entire machine, including hydraulic systems, screw and barrel, and heater bands. 2. Key Areas for Maintenance: Mold Cleaning: Remove any residue from cavities, runners, and vents, ensuring cleanliness for consistent part quality and preventing defects. Lubrication: Properly lubricate moving parts like ejector pins, slides, and guide pins to minimize friction and wear. Inspection: Regularly check for wear, damage, or misalignment of critical components like nozzles, screws, heater bands, and clamp components. Hydraulic System: Monitor oil levels, check for leaks, and ensure proper function of hydraulic components. Screw and Barrel: Inspect the screw and barrel for wear, especially in the compression/transition zone, and ensure proper fill time, cushion, and recovery. 3. Benefits of Preventive Maintenance: Improved Part Quality: Consistent maintenance helps maintain mold accuracy and reduces defects in the final parts. Reduced Downtime: Proactive maintenance identifies potential issues before they lead to major breakdowns, minimizing production interruptions. Cost Savings: Preventing failures is more cost-effective than dealing with repairs and replacements after a breakdown. Extended Mold Life: Proper maintenance can significantly extend the lifespan of the mold and reduce the need for premature replacement. Increased Profitability: By improving part quality, reducing downtime, and extending mold life, preventive maintenance can lead to increased profitability.
