Preventive vs corrective maintenance: which does your plant need?

The debate between preventive and corrective maintenance is one of the most common in industrial management. The answer isn't one or the other — it's knowing when to apply each.

What is preventive maintenance?

Preventive maintenance involves carrying out planned interventions before a failure occurs. Periodic inspections, lubrication, component replacement based on useful life, adjustments and calibrations.

When it's the best option:

• Critical machinery whose unplanned stoppage directly impacts production
• Equipment in sectors with strict regulations (food, pharmaceutical)
• High-cadence production lines where repair time is expensive

What is corrective maintenance?

Corrective maintenance is the intervention after failure. It can be reactive (waiting for failure) or planned (detecting deterioration and scheduling the repair).

When it makes sense:

• Redundant equipment where downtime doesn't impact production
• Auxiliary machinery with low cost and high spare parts availability
• Components with low replacement cost and unpredictable useful life

The optimal strategy: combine both

High-performance industrial plants don't choose between one or the other. They implement a mixed strategy based on criticality.

At Orca Industry we design the appropriate maintenance plan for each plant after a free prior diagnostic. No generic templates.
