FMCG Downtime Reduction: How to Reduce Production Line Stoppages

7 days ago

7 min read

In fast-moving consumer goods (FMCG) manufacturing, every minute of unplanned downtime can affect production output, delivery schedules, operating costs and customer satisfaction.

Whether you're running packaging machinery, bottling lines, conveyors, filling equipment or automated production systems, even a relatively minor fault can bring an entire production line to a standstill.

Effective FMCG downtime reduction isn't simply about getting machinery running again. It's about understanding why equipment fails, preventing repeat breakdowns and improving long-term production reliability.

At MechElecPro Solutions Ltd, we understand the pressures facing engineering and maintenance teams. With over 17 years of engineering experience, we provide practical mechanical, electrical and automation support to help UK manufacturers reduce downtime and keep production moving.

In this guide, we explore the common causes of FMCG production downtime and practical ways to improve equipment reliability.

What Causes Downtime in FMCG Manufacturing?

FMCG production environments often operate at high speeds, with multiple machines working together as part of a continuous process.

When one critical machine fails, the consequences can quickly spread throughout the production line.

Common causes of FMCG production downtime include:

Conveyor belt tracking problems and mechanical failures
Faulty sensors and photoelectric detection systems
Pneumatic cylinder and valve failures
Motor and gearbox breakdowns
PLC faults and industrial control system failures
Variable-speed drive faults
Packaging machine jams and feeding problems
Poorly maintained bearings and mechanical components
Incorrect machine settings during product changeovers
Delayed preventative maintenance

Some faults result in complete production stoppages, while others cause repeated short interruptions that gradually reduce manufacturing efficiency.

Identifying both types of losses is essential for improving production performance.

1. Identify the Biggest Causes of Production Downtime

One of the first steps towards reducing FMCG downtime is understanding where production losses occur.

Maintenance teams should record machinery failures and identify patterns rather than treating every breakdown as an isolated incident.

Useful information includes:

Equipment or production line affected
Date and time of the stoppage
Fault description and alarm codes
Duration of downtime
Root cause, where established
Repairs or temporary actions completed
Repeat failures or previous maintenance history

This information helps engineering managers prioritise the equipment responsible for the greatest production losses.

For example, a conveyor sensor that causes repeated 10-minute stoppages may create more downtime over a month than a single major breakdown.

By identifying recurring faults, manufacturers can focus engineering resources on improvements that deliver the greatest benefit.

2. Use Preventative Maintenance to Reduce Machinery Breakdowns

Preventative maintenance plays an important role in FMCG downtime reduction.

Instead of waiting for equipment to fail, planned maintenance helps identify developing problems before they result in unexpected production stoppages.

Typical preventative maintenance activities include:

Mechanical maintenance

Inspecting bearings, chains and gearboxes
Checking conveyor tracking and belt tension
Inspecting pneumatic cylinders and fittings
Checking lubrication requirements
Identifying worn or damaged components

Electrical maintenance

Inspecting electrical panels and connections
Checking motor and drive condition
Examining damaged cables and connectors
Inspecting sensors and safety devices
Reviewing electrical fault histories

Automation maintenance

Checking PLC and HMI fault logs
Maintaining programme and parameter backups
Reviewing obsolete control components
Verifying machine sequences and sensor operation

Maintenance intervals should reflect manufacturer recommendations, operating conditions, equipment criticality and failure history.

A well-structured maintenance programme can reduce unexpected breakdowns while helping engineering teams plan work around production requirements.

3. Reduce Repeat Breakdowns Through Root Cause Analysis

Repeated machinery failures are often a sign that the underlying problem has not been fully resolved.

For example, replacing a failed motor may restore production temporarily, but if the original failure was caused by excessive mechanical loading, the replacement motor could experience the same problem.

Effective root cause analysis involves investigating the complete system rather than simply replacing the failed component.

Engineers should consider:

What caused the machine to stop?
Which component or system failed?
What operating conditions contributed to the failure?
Has the same problem occurred previously?
Could maintenance or monitoring have identified the issue earlier?
What corrective action will prevent recurrence?

Where appropriate, the solution may involve modifying machinery, improving maintenance procedures, replacing unsuitable components or updating control systems.

The objective should be to eliminate recurring problems wherever reasonably practicable, rather than repeatedly responding to the same breakdown.

4. Improve Packaging Machinery and Conveyor Reliability

Packaging machinery and conveyor systems are essential components of many FMCG production lines.

Problems with carton erectors, case packers, filling equipment, labelling machines or conveyors can interrupt the flow of products and reduce overall production efficiency.

Common issues include:

Conveyor misalignment
Worn rollers and bearings
Incorrect sensor positioning
Pneumatic air leaks
Product jams
Incorrect machine timing
Worn mechanical guides
Unreliable product detection

Routine inspections and targeted machinery improvements can help prevent these issues from developing into repeated production stoppages.

For example, correcting a recurring conveyor tracking problem may reduce belt wear, prevent product handling issues and improve equipment reliability.

Maintenance teams should also consider how individual machines interact with upstream and downstream equipment.

5. Improve PLC and Automation System Reliability

Modern FMCG production equipment relies heavily on PLCs, variable-speed drives, sensors and industrial automation systems.

When these systems develop faults, identifying the cause quickly is essential.

Common automation problems include:

Intermittent PLC input or output faults
Obsolete control equipment
Failing sensors
Incorrect drive parameters
Poor electrical connections
Missing PLC programme backups
Unclear alarm messages
Communication failures between control devices

Planned PLC upgrades, improved fault diagnostics and suitable replacement components can help reduce production risks.

However, upgrading an entire control system is not always necessary.

In some situations, targeted improvements such as replacing obsolete modules, updating HMI alarm messages or improving sensor arrangements may provide a practical solution.

Any changes to machinery controls must be appropriately assessed, tested and documented, including their impact on machine safety.

6. Reduce Production Losses During Changeovers

Not all FMCG downtime results from equipment breakdowns.

Product changeovers, machine adjustments and inefficient restart procedures can also reduce available production time.

Common causes include:

Incorrect machine settings
Missing changeover components
Repeated sensor adjustments
Poorly documented setup procedures
Worn product guides
Delays restarting interconnected equipment

Standardised changeover procedures, clearly identified settings and well-maintained change parts can help improve consistency.

Where appropriate, maintenance teams can also investigate mechanical modifications or automation improvements that simplify changeovers.

Reducing changeover time can increase available production capacity without requiring additional machinery.

7. Ensure Adequate Engineering Shift Cover

Even the most effective maintenance programme can struggle when engineering resources are limited.

Holidays, sickness, increased production demands and unexpected breakdowns can place significant pressure on maintenance departments.

When engineers are constantly responding to production faults, planned maintenance tasks can be postponed.

Over time, this can lead to maintenance backlogs and declining equipment reliability.

Flexible engineering shift cover can help manufacturers maintain technical support during busy periods or temporary staffing shortages.

At MechElecPro Solutions Ltd, we provide experienced mechanical and electrical engineering support to work alongside existing maintenance teams.

Our services can help with:

Temporary engineering shift cover

This provides manufacturers with additional engineering resources without necessarily requiring permanent recruitment.

8. Prepare for Unexpected Industrial Breakdowns

Although preventative maintenance can reduce equipment failures, unexpected breakdowns cannot always be eliminated.

Having an effective breakdown response plan can reduce the time needed to diagnose faults and restore production.

A practical breakdown response plan should include:

Access to current electrical drawings
PLC programme and drive parameter backups
Critical spare parts
Machinery maintenance records
Clear fault escalation procedures
Suitable engineering support arrangements
Safe isolation and restart procedures

Manufacturers operating extended shifts should also consider how breakdowns will be managed outside normal working hours.

Access to experienced mechanical and electrical engineering support can be particularly valuable when internal maintenance resources are limited.

9. Measure the Real Cost of FMCG Production Downtime

Understanding the financial impact of production downtime can help businesses justify maintenance improvements.

Consider a production line where downtime is estimated to cost £1,000 per hour.

If recurring machinery faults cause five hours of lost production each week, the estimated annual impact could be substantial.

Example calculation:

Estimated downtime cost: £1,000 per hour
Downtime: 5 hours per week
Operating weeks: 50 per year
Estimated annual downtime cost: £250,000

This is an illustrative calculation, not an industry benchmark. Actual costs depend on production margins, recoverable output, labour, waste and other operating factors.

Reducing those losses by just 20% could represent an estimated £50,000 annual benefit under the same assumptions.

This demonstrates why even relatively small engineering improvements may justify investment when they prevent recurring production stoppages.
