How to Improve Production Line Reliability and Reduce Downtime
Updated: 3 days ago
In manufacturing, an unexpected production line breakdown can quickly lead to lost output, increased costs, missed delivery deadlines and unnecessary pressure on maintenance teams.
Whether it is a conveyor failure, electrical fault, worn mechanical component or PLC issue, even a relatively small problem can bring an entire production line to a standstill.
Improving production line reliability is not simply about repairing machinery when something goes wrong. It involves identifying potential failures, maintaining critical equipment, supporting engineering teams and making sure the right resources are available when they are needed.
At MechElecPro Solutions Ltd, we provide mechanical, electrical and automation engineering support to manufacturing businesses across the UK, helping clients maintain equipment, address reliability issues and reduce avoidable production downtime.
In this guide, we explore practical ways to improve production line performance and build a more reliable manufacturing operation.
Why Production Line Reliability Matters in Manufacturing
Reliable production equipment is essential for maintaining consistent output, product quality and operational efficiency.
When machinery operates as expected, production teams can work to planned schedules, maintenance activities can be coordinated and businesses can manage resources more effectively.
However, when equipment failures become frequent, the consequences can extend far beyond the initial repair.
Common problems include:
Lost production hours and reduced output
Increased maintenance and repair costs
Unplanned overtime and additional labour requirements
Delays in customer orders
Increased pressure on engineering and production teams
Product quality issues and material waste
Greater risks associated with rushed repairs and repeated failures
Improving reliability helps manufacturers move away from constantly reacting to breakdowns and towards a more controlled, preventative approach.
1. Identify the Main Causes of Production Downtime
Before improving production line reliability, businesses need to understand why their machinery is stopping.
Not every breakdown has the same cause, and repeatedly repairing symptoms without identifying underlying problems can result in recurring failures.
Typical causes of industrial machinery downtime include:
Mechanical failures
Worn bearings, damaged conveyor belts, failing gearboxes, misaligned components and insufficient lubrication can gradually affect machine performance.
Electrical faults
Damaged cables, faulty sensors, motor failures, loose connections and deteriorating electrical components can interrupt production unexpectedly.
PLC and automation problems
Control-system faults, communication errors, damaged input/output modules and incorrect settings can affect automated production equipment.
Maintenance backlogs
When planned maintenance is repeatedly postponed, relatively minor issues can develop into more serious equipment failures.
Engineering resource shortages
A lack of available maintenance engineers can delay fault diagnosis, repairs and essential preventative maintenance.
By reviewing breakdown records, recurring faults and equipment history, manufacturers can identify where engineering improvements will have the greatest impact.
2. Improve Production Line Reliability with Preventative Maintenance
One of the most effective ways to reduce unexpected breakdowns is through a well-planned preventative maintenance programme.
Rather than waiting for machinery to fail, preventative maintenance focuses on inspecting, servicing and maintaining equipment at appropriate intervals.
Depending on the equipment and manufacturer requirements, this may include:
Inspecting conveyor belts, chains and drive systems
Checking bearings, gearboxes and lubrication
Monitoring motors and electrical connections
Inspecting sensors and control components
Checking pneumatic and hydraulic systems
Identifying signs of excessive wear or vibration
Reviewing recurring equipment faults
Completing necessary repairs during planned shutdowns
A successful maintenance programme should be based on equipment criticality, operating conditions, manufacturer recommendations and actual failure history.
At MechElecPro Solutions Ltd, we provide industrial machine servicing and planned maintenance support, helping manufacturers address developing issues before they cause unnecessary disruption.
3. Address Recurring Machinery Breakdowns
A machine that repeatedly fails may be indicating a deeper engineering problem.
For example, a conveyor that regularly trips could be experiencing excessive mechanical resistance, incorrect belt tension, motor overload or an intermittent sensor fault.
Simply resetting the equipment may restore production temporarily, but it does not necessarily address the cause.
A structured fault-finding approach should involve:
Reviewing the machine's fault history and operating conditions.
Identifying the symptoms and potential causes.
Carrying out appropriate mechanical, electrical or control-system checks.
Confirming the underlying fault wherever possible.
Completing suitable repairs or corrective actions.
Testing the equipment safely before returning it to production.
Recording the findings to help prevent recurrence.
Effective fault finding can reduce repeated call-outs, unnecessary component replacement and avoidable downtime.
4. Keep Critical Spare Parts Available
A relatively inexpensive component can cause significant production losses if a replacement is not available.
For example, a failed sensor, motor contactor or drive component could stop an entire production line while the maintenance team waits for parts.
Manufacturers should identify critical equipment and assess which spare parts are essential for maintaining operations.
This may include:
Sensors and proximity switches
Motor contactors and overload devices
Bearings and mechanical drive components
Conveyor belts and chains
Pneumatic valves and cylinders
Variable speed drives
PLC modules and control-system components
Not every component needs to be held in stock.
A sensible spare-parts strategy should consider failure probability, replacement lead time, equipment criticality and the consequences of downtime.
5. Maintain PLC and Automation System Reliability
Modern manufacturing relies heavily on PLCs, HMIs, variable speed drives and automated control systems.
Although these systems can operate reliably for many years, poor documentation, outdated hardware and unavailable programme backups can make recovery from a failure significantly more difficult.
To improve automation reliability, manufacturers should consider:
Maintaining current PLC and HMI programme backups
Recording changes to control-system settings
Reviewing obsolete or unsupported components
Keeping electrical drawings and documentation updated
Checking the availability of replacement control components
Investigating recurring automation faults
Planning suitable PLC and control-system upgrades
Any control-system modifications should be properly assessed, tested and documented, including consideration of machinery safety requirements.
MechElecPro Solutions Ltd provides PLC programming, fault finding and automation engineering support, helping manufacturers maintain and improve existing equipment.
6. Reduce Maintenance Backlogs Before They Affect Production
Maintenance backlogs can develop when engineering teams are constantly responding to urgent breakdowns.
Planned servicing, inspections and minor repairs may be postponed because production demands take priority.
Over time, this can increase the likelihood of equipment failures.
To manage maintenance backlogs effectively, businesses should:
Prioritise safety-critical and production-critical work.
Identify jobs that could develop into major failures.
Schedule maintenance around production requirements.
Allocate appropriate engineering resources.
Review outstanding maintenance activities regularly.
Use additional engineering support when internal capacity is limited.
Bringing in experienced contract engineers can help businesses complete essential maintenance without placing further pressure on existing teams.
7. Use Engineering Shift Cover to Maintain Reliability
Production line reliability depends on having the right engineering skills available when equipment requires attention.
When maintenance engineers are absent due to holidays, sickness, vacancies or increased workload, production sites can become more vulnerable to unexpected downtime.
Engineering shift cover can provide additional support during these periods.
Experienced contract engineers can assist with:
Responding to machinery breakdowns
Completing planned maintenance
Supporting production teams
Carrying out mechanical and electrical repairs
Addressing maintenance backlogs
Providing engineering support during busy production periods
At MechElecPro Solutions Ltd, we provide flexible engineering shift cover to manufacturing businesses across the UK.
Our aim is to help clients maintain engineering capacity and support operational continuity without unnecessary disruption.
8. Improve Communication Between Production and Maintenance Teams
Operators are often the first people to notice changes in machine performance.
Unusual noises, vibration, intermittent faults, slower cycle times and inconsistent product quality may all indicate developing equipment problems.
Encouraging operators to report these issues early can help maintenance teams investigate faults before they become more serious.
Effective communication should include:
Clear reporting of machinery faults
Accurate breakdown and maintenance records
Shift handovers between engineering teams
Recording temporary repairs and outstanding work
Regular discussions about recurring equipment issues
Feedback following major breakdowns
When production and maintenance teams share information effectively, engineering resources can be directed towards the problems that matter most.
9. Measure Production Line Performance
Manufacturers cannot effectively improve reliability without understanding how their equipment is performing.
Monitoring a small number of relevant maintenance and production indicators can help identify trends and measure improvements.
Useful indicators include:
Machine availability: The percentage of planned production time that equipment is available to operate.
Mean Time Between Failures (MTBF): A measure of the average operating time between repairable failures.
Mean Time to Repair (MTTR): The average time required to repair equipment and restore its function, based on a consistently defined measurement.
Overall Equipment Effectiveness (OEE): A measure combining availability, performance and quality.
Recurring breakdowns: Tracking repeated faults helps identify equipment requiring further investigation.
These measures should be used alongside practical engineering observations rather than treated as targets in isolation.
10. Build a Production Line Resilience Plan
Even well-maintained machinery can experience unexpected failures.
A production line resilience plan helps manufacturers prepare for disruptions and restore operations safely and efficiently.
An effective plan should identify:
Production-critical machinery and systems
Likely failure points and operational risks
Available spare parts and specialist equipment
Internal engineering capabilities
External engineering support arrangements
PLC backups and technical documentation
Safe shutdown and restart procedures
Escalation arrangements for major breakdowns
It is also worth considering what would happen if a key engineer were unavailable, a critical component failed or an essential spare part had a long delivery time.
Preparing for these situations in advance can help reduce delays when unexpected problems occur.
