Spare Parts Inventory for Molded Pulp Machines: Keeping Critical Spares Without Overstocking

Molded-pulp lines depend on consumable parts — screens, seals, bearings, and belts — and a missing part can idle the line for days waiting on shipment. A smart spares strategy classifies parts by criticality and lead time, stocking the parts that stop the line while avoiding overstock on everything else.

The Scenario: Three challenges in spares

Spare-parts management faces three challenges:

Pain Points

• Consumable parts wear on different cycles, so stocking everything is expensive;
• A single missing critical part can idle the whole line waiting on shipment;
• Overstock ties up cash and shelf space without reducing risk.

The Solution: Three spares-management solutions

A spares strategy offers three solutions:

1. Criticality classification Classify parts as critical or non-critical based on whether failure stops the line.

2. Lead-time-aware stocking Stock more of parts with long lead times and less of parts available locally.

3. Reorder triggers Set min/max levels and reorder triggers so critical spares never run out.

The Result: No idle line, no overstock

With these solutions, critical spares are always on hand while cash isn't tied up in overstock. Smart spares management keeps the line running and the balance sheet lean.
