Optimising Production: How Smart Maintenance Technologies Are Changing the Game
Published on 21 January, 2025 in Operational Excellence
Unplanned downtime is sabotaging production goals. It's time to take action.
Unexpected machine stoppages aren't just inconveniences—they represent costly disruptions that derail schedules, increase operational expenses, and reduce profitability. Efficiency and reliability are crucial factors for maintaining competitiveness in manufacturing, so, minimising productivity losses such as unplanned downtime must be a strategic priority for both small and medium enterprises (SMEs) and large corporations.
But what if you could anticipate equipment failures before they happen, deploy machines designed with maintenance in mind, and minimise fault finding? Smart maintenance technologies are making all of these a reality, transforming operations from reactive firefighting to proactive problem-solving.
In this blog, we’ll explore how predictive maintenance, intelligent machine design, and advanced diagnostics are helping manufacturers reduce downtime, optimise costs, and stay ahead in an ever-evolving industry.
Predictive Maintenance: Prevent Problems Before They Occur
Don't wait for equipment to fail—take charge by predicting and preventing issues before they disrupt your production line. Predictive maintenance leverages real-time data analytics to foresee when equipment might go down. By continuously monitoring machine health through sensors and other Internet of Things (IoT) devices, maintenance activities can be scheduled before a breakdown happens.
Understanding Predictive Maintenance
Basically, predictive maintenance is about collecting data from equipment and using analytics to identify patterns that indicate potential failures. By monitoring various parameters such as temperature, vibration, insulation, and torque—and analysing this data, often using machine learning algorithms—we can predict when key components like AC motors, heaters, or servos might fail or require servicing.
Real-World Example
Consider a simple conveyor system transporting small boxes of finished goods to end-of-line packaging. Under normal conditions, we expect a certain level of wear on the belt motor, which correlates directly with the load on the belt. Maintenance activities are typically scheduled based on these normal conditions. However, if debris becomes trapped in the belt chain, the motor must work harder, thereby reducing its lifespan. If this issue isn't quickly identified, an unexpected motor breakdown becomes inevitable.
By monitoring the motor's current draw and comparing it against expected values, we can swiftly detect abnormalities, address them proactively, and ensure that the belt motor doesn't fail unexpectedly. This proactive approach helps maintain operational efficiency and prevents costly downtime.

Benefits
Predictive maintenance offers several significant benefits to manufacturing operations:
Reduced Downtime: By predicting potential failures before they occur, businesses can minimise unplanned stoppages. This proactive approach helps maintain smooth production schedules, avoiding costly disruptions and ensuring that operations remain efficient.
Cost Savings: Preventative maintenance is generally more cost-effective than dealing with emergency repairs. By identifying and addressing issues early through predictive analytics, companies can save on repair expenses and prevent losses associated with downtime and interrupted production.
Extended Equipment Life: Timely maintenance not only prevents breakdowns but also extends the operational lifespan of machinery. This not only enhances reliability but also optimises the return on investment in equipment, supporting long-term profitability and sustainability.
Overall, predictive maintenance not only enhances operational efficiency but also contributes to cost savings and extends the longevity of critical equipment, making it a strategic imperative for modern manufacturing environments.
Intelligent Machine Design: Equip Yourself for the Future
Equip your operations with machines that evolve alongside your needs.
Designing equipment with smart technologies from the start ensures machinery remains adaptable to future innovations and trends. Features like advanced communication protocols, embedded diagnostics, and modular components not only enhance reliability but also simplify maintenance.
Key Components of Intelligent Machine Design
Modern manufacturing systems benefit significantly from advanced technologies designed to enhance efficiency and reliability.
Advanced Communication Networks and Protocols like IO-Link, EtherCAT, or OPC UA play a crucial role by enabling seamless data exchange between devices and systems. These protocols facilitate real-time monitoring and control, ensuring operations remain responsive and adaptive to changing conditions.
To compliment this, remote connectivity to machinery in manufacturing enhances efficiency by allowing proactive monitoring and real-time issue diagnosis. It enables speedy intervention and troubleshooting, reducing downtime and ensuring minimal disruption to production schedules. This capability also supports proactive maintenance strategies, leveraging predictive analytics to anticipate failures and schedule repairs promptly. Additionally, remote connectivity facilitates remote updates and troubleshooting, ensuring continuous performance improvement and reduced operational costs.
Real-World Example
Imagine a critical assembly line machine suddenly experiencing a breakdown due to a faulty sensor. This issue leads to a complete halt in production, causing significant downtime and impacting delivery schedules. In the past, diagnosing such problems required on-site technicians to physically inspect the machine, often leading to delays in identifying the root cause and initiating repairs.
With remote connectivity capabilities implemented, however, the situation unfolds differently. Upon detecting abnormal sensor readings, the machine automatically sends alerts to the maintenance team via the remote monitoring system. Using real-time data and diagnostic tools, engineers can rapidly analyse the problem without needing to be physically present on the shop floor, or even in the factory at all. They pinpoint the faulty sensor, confirm the issue through virtual diagnostics, and either perform or instruct the appropriate remedial action.
This streamlined approach minimises downtime drastically, as the machine can resume normal operations swiftly after the issue is identified and resolved remotely. By avoiding the delays associated with on-site troubleshooting, the company mitigates production losses, maintains delivery commitments, and enhances overall operational efficiency.
Implementation Strategies
- Collaborate with Machine Builders : When commissioning new equipment, specify requirements that include smart technologies. Early collaboration ensures that machines meet your current and future needs.
- Adopt Industry Standards : Use standard protocols to ensure compatibility and interoperability between different devices and systems.
- Plan for Remote Access : Engage machine builders that have extensive experience in remote diagnostics and engage them with your IT team to ensure seamless integration.
- Focus on User Experience : Design intuitive interfaces to reduce the learning curve for operators. User-friendly machines increase productivity and reduce errors.
Benefits
Deploying intelligent machinery offers manufacturers, regardless of their size, opportunities to significantly enhance operational effectiveness.
Immediate monitoring of production processes: ensures prompt identification and resolution of any abnormalities or issues. This proactive approach contributes to maintaining consistent product quality and high production efficiency.
Drastically reduced repair times: particularly beneficial when technicians are situated in different countries. Beyond evident cost and sustainability advantages, the primary value lies in quickly restoring full production capacity.
Enhanced overall equipment effectiveness (OEE): enables manufacturers to sustain continuous production, meet delivery commitments, and maximise output. This improvement boosts productivity, increases profitability, and strengthens competitiveness within the market.
Advanced Diagnostics: Fix Problems Faster
When equipment malfunctions without an obvious cause, it can be a nightmare for maintenance teams. Traditional diagnostics might not reveal intermittent faults or issues that occur under specific conditions. This is where advanced diagnostics come into play, offering innovative ways to identify and resolve elusive problems.
Replaying System Events to Trace Problems
Imagine having the ability to "rewind" your production line to see exactly what happened before a fault occurred. Advanced diagnostic tools now enable engineers to record and replay videos of the machine whilst in operation, providing a detailed snapshot of system performance and environmental factors leading up to an issue. This replay functionality can uncover anomalies that are otherwise impossible to detect, such as inadvertent operator interference or environmental disturbances.
Real-World Example
Imagine a packaging facility experiencing intermittent stoppages on one of its high-speed lines. The faults are sporadic and don't leave obvious clues, making them difficult to troubleshoot. By utilising video-based diagnostics with playback capabilities, the maintenance team can record the machine processes over time. After reviewing the recordings and matching them to process data traces, they can identify that an operator is stopping the machine when it doesn’t need to be stopped. Retraining the operator on correct machine procedures easily addresses the behaviour, eliminating costly downtime.
Implementation Strategies
- Integrate Recording Functions : Equip your control systems with the ability to log and replay machine processes. This feature captures detailed operational data that can be matched to video footage and reviewed when issues arise.
