Problems solved by technology

However, under the existing technology, many aluminum profiles have complex manufacturing processes, low yields, and unstable product quality.
At present, the strength of aluminum alloy profiles in my country is not particularly high, and it is easy to twist or deform after long-term use. This shortcoming limits the application of aluminum alloy profiles in some markets that require high strength.
