Metal stamping refers to pushing a metal sheet into a stamping die, and using the pressure of a punch press to transmit it to the stamping die to complete the required metal stamping parts.

In modern manufacturing, aluminum, thanks to its low density, high specific strength, and corrosion resistance, has become a core material across many sectors. Aluminum welding technology is crucial for joining aluminum components and directly determines product lifespan and safety. In addition to traditional hot welding, processes such as cold welding are now also being used in specific applications, but they still face challenges stemming from material properties.

As mentioned above, although aluminum has a low melting point and good ductility, in actual production, problems such as work hardening, die sticking, and temperature sensitivity often lead to stretching failures. This article will provide a systematic aluminum stretching solution, from material selection to process optimization, to help you improve production efficiency and product quality.

Aluminum metal has a melting point of only 660°C. Generally speaking, a lower melting point facilitates stretching. However, why is the actual stretching process so challenging? Kailai Machinery, drawing on 30 years of experience in custom metal parts processing, will help you answer this question.

In metal welding, welding distortion is a common and critical issue that affects part precision and performance. Whether it's a small precision component or a large structural part, factors such as uneven heat input and differential material shrinkage during metal welding can lead to welding distortion, increasing subsequent correction costs and even causing part scrap. Therefore, mastering scientific methods for controlling welding distortion is crucial for optimizing metal welding processes and improving product quality.

In the metal welding technology system, secondary welding is not a standalone welding method. Rather, it is a re-welding operation performed on a welded joint after the primary welding (initial welding) of a metal material is completed to repair defects, enhance strength, achieve proper fit, or optimize performance. It is a critical supplementary process that compensates for deficiencies in primary welding and ensures metal welding quality. It is widely used in high-precision applications such as pressure vessels, steel structures, and aerospace, and is considered the "last line of defense" for metal welding quality control.
