Reasons for the shrinkage of the tail during the processing of aluminum profiles

Analysis of the causes of tail shrinkage in the process of aluminum profile processing

Aluminum profile processing is a precise and complex process, in which the tail is a possible problem. Shrinkage refers to the phenomenon of shrinkage, depression or irregularity of the tail during the processing of aluminum profiles. The following will be a detailed analysis of the reasons for the shrinkage of the tail during the processing of aluminum profiles.

1. material factors

The material and performance of aluminum profiles are important factors affecting the shrinkage. Aluminum profiles of different materials have different physical properties such as thermal expansion coefficient and thermal conductivity, which may lead to different tail shrinkage during processing.

Improper setting of 2. process parameters

The process parameters in the processing process, such as temperature, pressure, speed, etc., have a direct impact on the forming of aluminum profiles. Improper parameter setting may cause the tail of the aluminum profile to shrink during processing.

3. mold design problems

The design of the die has a decisive influence on the processing quality of the aluminum profile. Unreasonable mold design, such as improper mold cavity size design, unreasonable gate location, etc., may lead to the phenomenon of shrinkage in the process of aluminum profile processing.

4. casting process problems

When casting aluminum profiles, if the casting temperature is too high or too low, the fluidity of the molten metal is poor, and the filling is insufficient or overfilled, it may cause the tail of the aluminum profile to shrink. In addition, the structural design of the casting will also affect the tail shrinkage.

Improper 5. heat treatment

Heat treatment is the heavy in the process of aluminum profile processing.
