Unique hemming technology to prevent pinhole leakage

2021-11-12 11:01

In modern manufacturing, details often determine success or failure. Especially in areas that require high sealing and precise control, such as aerospace, medical devices, and automobile manufacturing, any tiny leak may lead to serious consequences. Pinhole leakage, as one of the common and difficult-to-detect problems, has long troubled many engineers and technicians. However, with the advancement of science and technology and the innovation of processes, a unique hemming technology has emerged, providing a new solution to effectively solve the problem of pinhole leakage.

1. Hazards and challenges of pinhole leakage

Pinhole leakage refers to tiny holes formed at the material connection due to tiny flaws in the processing process or tiny defects in the material itself. Although these holes are small in size, they are enough to allow gas, liquid or pressure to leak in places where they should not flow. In industrial production, this leakage not only leads to waste of resources and environmental pollution, but more importantly, it may cause safety accidents and threaten the lives of people and equipment safety.

For example, in the aerospace field, the fuel system of the rocket engine remains sealed, and any tiny leak may lead to insufficient thrust or explosion; in medical devices, leakage of hemodialysis equipment may cause patient infection or treatment failure; and in automobile manufacturing, leakage of the fuel system will not only pollute the environment, but also cause fire. Therefore, how to effectively prevent pinhole leakage has become a major challenge faced by the industry.

2. Limitations of traditional solutions

The traditional methods to prevent pinhole leakage mainly include strengthening material testing, optimizing processing technology, using sealants or gaskets, etc. These methods can reduce the occurrence of leakage to a certain extent, but they all have their limitations. Although material testing can screen out defective products, it cannot fundamentally solve the problem; optimizing processing technology can improve product quality, but it is costly and difficult to achieve zero defects; although sealants and gaskets can temporarily block leakage points, they are prone to aging and failure under long-term use, and increase the complexity of the system.
