The purpose of cleaning is to ensure that the processed parts of aluminum production equipment reach a certain degree of cleanliness. How to detect and evaluate the cleanliness of the surface of aluminum profile processing parts? Different workpieces have different requirements for performance and reliability due to different cleaning purposes. Therefore, the requirements for cleanliness are also different. The content of cleanliness detection and evaluation, The methods are also different.

Industrial aluminum profiles are an alloy material with aluminum as the main component. Aluminum materials with different cross-sectional shapes are obtained by hot-melting and extruding aluminum rods. However, the proportions of the added alloys are different. The mechanical properties of the industrial aluminum profiles produced are It is also different from the application field.

Bubbles or peeling: convex bubbles appear on the surface of the product, often at the head and tail. Complete ones are called bubbles, and broken ones are called peeling.

There are three processing methods for industrial aluminum profiles: anodizing, electrophoretic coating and powder spraying. Each of them has its own advantages and occupies a considerable market share.

Hollow aluminum profiles and solid aluminum profiles are both extruded after heating aluminum rods. The difference between the two lies in the use of different extrusion dies. So what specific extrusion dies are used for the two profiles?

No matter what specification of industrial aluminum profile it is, there are holes of various sizes on its cross-section. So what are the functions of these holes? Let’s learn about it together.
