Introduction
When it comes to the manufacturing of industrial parts, safety is the utmost concern. It is imperative that the integrity and quality of the parts are maintained through strict quality checks and measures. Despite this, there are cases where forged parts make their way into the supply chain, leading to catastrophic consequences. In this article, we will delve into the topic of forged parts, their potential dangers, and an example of a forged part.
What are forged parts?
Forging is a manufacturing process that involves shaping metal using compressive forces. Forged parts are machined by heating up a workpiece until it reaches a malleable state, then applying controlled force to shape it into the desired form. This process results in parts that are stronger and denser than those made by other manufacturing methods, such as casting.
The potential dangers of using forged parts
Although forged parts tend to be stronger and more durable than other parts, it is essential to note that not all forged parts are created equal. One of the primary concerns is the use of counterfeit or substandard materials, which can lead to parts that are not only inferior in quality but potentially dangerous.
In industrial applications, these substandard parts can cause equipment failure, leading to accidents, injuries and even fatalities. A study conducted by the U.S. Government has shown that tens of thousands of accidents that happen each year are due to worn or defective parts. When it comes to forged parts, the risk of failure is even greater if the forgery is not detected early on.
Detecting forged parts
With the severe consequences of using forged parts, it is an essential practice to have quality checks and measures in place to detect them. One common method is visual inspection, which involves a thorough examination of a part''s physical characteristics. Another method is the use of non-destructive testing techniques such as ultrasound or x-ray to identify any differences in the internal structure of the metal.
Despite this, many instances of forged parts making their way into the supply chain are detected only after the damage has been done. The use of counterfeit or substandard materials can create a ticking time bomb that can go unnoticed until it is too late.
Example of a forged part
One example of a forged part is the Takata airbag, which is responsible for at least 27 deaths worldwide and hundreds of injuries. The airbag used ammonium nitrate as its propellant, which was prone to degradation over time due to heat and humidity. As a result, in the event of an accident, the airbag could rupture, hurling shrapnel at the driver and passengers.
Investigations have revealed that Takata knowingly used counterfeit materials in the manufacturing of their airbags to cut costs. The counterfeit materials were cheaper and easier to obtain than the genuine materials. This decision led to a catastrophic failure, demonstrating the danger of using fake or substandard parts in industrial applications.
Conclusion
The use of forged parts in industrial applications can lead to disastrous consequences. The potential risks associated with substandard parts, and the difficulty of detecting them, highlight the importance of stringent quality checks and measures. It is essential to ensure that the parts used in industrial applications are genuine and of high quality. Failure to do so can lead to accidents, injuries, and even fatalities, as seen in the case of the Takata airbags.
