If a critical component cracks, breaks or becomes damaged during manufacture or use, it can cause immediate problems. The production can cease, customers can be unhappy, and the costs can quickly add up. A minor fault in a product could turn into a costly product recall if it is part of a product that has already been sent to thousands of customers.
Each faulty component has a story to tell, however. Manufacturers should look at the root cause of the failure, rather than just replacing the failed component.
That is where professional failure analysis services come in handy. Failure analysis is not simply an examination of the visible failure, it is an investigation that determines the actual cause of the failure. This can help manufacturers to identify the cause of the issue in order to prevent it from impacting additional products and causing expensive recalls.
Finding the Real Cause of Material Failure
Many people think that, when a metal part breaks or a plastic part cracks, the material was just too weak. In practice, there are numerous reasons why materials may fail. The fracture surface provides information about what happened before the component failed. With the proper equipment, a professional failure analysis lab will be able to explore these details and find problems that are not seen with the naked eye. Some common causes include:
- Fatigue cracks: Small cracks appear over time as a result of repeated stress, vibration or strain. They develop gradually and eventually cause failure.
- Environmental degradation and corrosion: They can be degraded by environmental conditions, chemicals, or high temperatures, leading to unexpected failure.
- Manufacturing defect: Trapped gas, poor welding, improper heat treatment, small internal voids, etc. can cause a component to be weaker than it should be even before it reaches the customer.
After a failure has been identified, engineers can stop guessing and concentrate on the actual cause of failure rather than relying on temporary fixes.
How One Defective Part Can Lead to a Product Recall
Most product recalls aren't because of one faulty component. Typically, they arise when there is a common defect in numerous products. Suppose a company produces steering parts for vehicles in the commercial transport sector. When one component fails, because of casting defect, it can be a random occurrence. However, if thousands of the same component were manufactured using the same manufacturing method, there would be many more faults. Professional failure analysis helps in deciding if the failure was caused as a result of an unusual event or a significant manufacturing or design problem. This information can be useful for manufacturers to fix the issue before more units fail, which could prevent a large recall.
Move from Problem Solving to Problem Prevention
Learning about failure is the greatest advantage of professional failure analysis. It also helps in reducing reoccurrence of similar defects in future products. Failure investigation results are useful for engineering, research and development and quality control teams. If a material fails during continuous vibration testing, for instance, then the engineers can choose a different material or modify the design of the component before it is produced again. It's a continuous improvement initiative that supports manufacturers to build safer, stronger and more reliable products.
Methods of Failure Analysis to Improve the Quality of Products
The following are some of the major advantages of professional failure analysis:
- Is able to pinpoint the root cause of product failure
- Assists in avoiding subsequent errors
- Contributes to product quality and reliability
- Facilitates improved engineering decisions
- Minimizes warranty issues and repairs
- Reduces the potential for expensive product recalls
- Maintains customer trust and brand reputation
Manufacturers should not wait for failures to happen to improve product performance, but can do so through failure analysis.
A Valuable Investment for Manufacturers
Some companies regard failure analysis as being an extra cost. In fact, it is an investment that can save a lot of time and money. Investigating a faulty part can cost a lot less than a product recall, a lawsuit, production delays, or harm to a company's reputation. Failure analysis is a professional and scientific process that gives manufacturers the data they need to decrease future risk, enhance materials and manufacturing techniques, and optimize product design.
Conclusion
Each failed component offers a lot of information for why and how a product failed. Professional failure analysis services assist manufacturers to determine the cause of failure, rather than just replacing failed parts.
Defects in the material, in production, environmental damage, or design flaws can all be identified, helping companies to prevent future failures, improve product quality, and prevent expensive recalls.
Manufacturers can consider failure as a means to enhance product quality, refine the quality control system, and boost customer trust. The manufacturing industry is highly competitive, and professional failure analysis is an integral part of manufacturing and of producing safer and more reliable products to ensure success in the long run.
Collaborating with a failure analysis lab experienced in the field further contributes to manufacturers quality management systems and production efficiency. The knowledge gained from failures can help businesses select more appropriate materials, improve production methods, and decrease risks in the future. The investment in professional failure analysis safeguards both products and customers. It also supports long-term growth, improves operational excellence, and strengthens a company's reputation in today's competitive manufacturing industry.
