How to Reduce Machine Downtime: Strategies for Manufacturers
If you often need to replace your machines or get hit with equipment failure, you are likely facing unplanned downtime. As a manufacturer, dealing with unplanned downtime and equipment failures can create major operational obstacles.
- Production halts can deplete your inventory and without backup machines, catching up can take days or even months.
- One of the most visible impacts is lost production capacity. For instance, if your unit produces 300 units per hour at a $40 profit per unit, one hour of downtime costs over $11,000 in lost revenue.
- A malfunction in one part of your plant increases stress on other parts, causing further problems and added load.
But what if you could turn this around? Downtime doesn't have to be such a headache. With the right strategies, you can reduce downtime and schedule planned maintenance during convenient slots.
In this article, we'll provide a comprehensive overview of machine downtime and offer practical strategies to reduce it. By following these steps, you can keep your production lines running smoothly without equipment failures.
What is Machine Downtime?
Machine downtime happens when a machine stops working and can't be used for production. If you are a manufacturer, handling downtime is crucial to maintain productivity and profitability. There are two main types of downtime:
Planned Downtime
Planned downtime includes any scheduled stoppage of the manufacturing process. While it temporarily halts production, planned downtime is essential for long-term reliability. For example, scheduled maintenance during off-peak hours can prevent unexpected downtime and improve your Overall Equipment Effectiveness (OEE).
Some examples of a planned downtime event are:
- Regular maintenance
- Upgrading equipment
- Production line changes
- Shift and product changeovers
Unplanned Downtime
Unplanned downtime occurs without warning due to equipment failures, human errors, or unforeseen external factors. This is a costly downtime, creating production delays, increased labor costs, and urgent maintenance expenses for you.
Unplanned downtime commonly occurs as a result of:
- Equipment failure
- Material shortages
- Human errors
To reduce unplanned downtime, you can adopt a data-driven approach. For instance, using sensors and monitoring systems can help detect potential issues before they lead to significant problems.
Causes of Machine Downtime
Statistics reveal that the cost of downtime in the manufacturing industry is estimated to be almost $50 billion annually. Therefore, understanding the causes is crucial if you want to work toward reducing downtime.
Here are some common reasons why you might be facing unplanned machine downtime:
- Mismanaged Supply Chain: If you are running out of inventory, spare parts, or resources like fuel, this can stop the production process, leading to unexpected downtime events.
- Lack of Planning: When your maintenance team lacks data on maintenance needs, it can lead to unplanned downtime and lost production time.
- Equipment Malfunctions: Machinery malfunctions are a significant cause of downtime. If your heavy equipment often faces high stress, it can result in overheating, wear and tear, and overall downtime.
- Untrained Workforce: Untrained employees are more likely to make mistakes that can result in equipment failure. Therefore, proper training is important to confirm that your operators know how to use and maintain machinery correctly, reducing the risk of accidental damage.
- Power Outages: Frequent power supply issues can disrupt your production line, especially for equipment that relies on electricity or requires software and internet connectivity.
How to Calculate Machine Downtime
To reduce unplanned downtime, you first need to understand its extent. This will help you identify which equipment is most prone to failure and critical to your manufacturing operations.
Here are some steps to track downtime:
- Identify Planned Operating Time: Determine the total operating time for a set period. For example, if production runs 8 hours a day for 20 days a month, that's 160 hours per month.
- Tracking Downtime: Track the actual downtime during this period by using current data or consulting previous reports if available.
- Calculate Actual Operating Time: Subtract the recorded downtime from the planned operating time. This gives you the actual operating time.
- Convert to Percentage Downtime is often expressed as a percentage. Use the formula:
Unplanned Downtime = (Time Asset is Down / Planned Operating Time) x 100
This can be applied to individual machines, shifts, departments, or the entire facility.
How to Reduce Machine Downtime
Once you have carried out a downtime analysis, you can start working toward minimizing it. Reducing downtime is crucial if you want to maintain profitability and consistency in your processes.
Here are some strategies to help you achieve this goal:
Perform a Risk Audit
A risk audit identifies potential issues with your equipment which is a critical marker for reducing downtime. For example, an old machine in your manufacturing plant that's 17 years old is at high risk for failure and may be difficult to find spare parts for.
By auditing your equipment, you can get a better idea about which machines are obsolete and should be replaced at higher priority. Regular audits also help you confirm that your manufacturing equipment meets safety standards, protecting your team and preventing costly disasters.
Here are some tips for a successful risk audit:
- Identify machinery that is nearing the end of its lifecycle.
- Make sure the spare parts and support are available. If they are not, this is hinting toward the obseleteness of the equipment.
- Determine if old equipment poses any safety hazards.
Implement Real-Time Monitoring
Use real-time monitoring systems with sensors and data analytics to track equipment performance and reduce downtime. Most of these systems can send alerts to mobile devices and display dashboards in production areas, providing transparency and facilitating immediate intervention.
For example, if a machine's temperature exceeds a certain threshold, an alert can prompt a technician to address the issue before it leads to unplanned downtime events. This can help you identify patterns, and predict equipment failures.
Create a Preventive Maintenance Schedule
Preventive maintenance involves regular checks and servicing of equipment to prevent unexpected breakdowns. It is a good idea to schedule your plant's maintenance during planned downtime for part replacement and make sure that proper personnel are available during that time.
This proactive approach will help you catch issues early, order spare parts in advance, and avoid any overtime costs. Here are some key components of preventative maintenance that you should keep in mind:
- Scheduled inspections
- Part replacements during planned downtime
- Routine maintenance schedules during normal operations
