With the emergence of industrial automation, the industry's requirements for the precision of production materials are getting higher and higher. The birth of aluminum profile lean tubes has simplified the production process and materials at the same time, in line with the strict requirements of modern industry for lean production. For aluminum profile lean tubes The production and processing of pipes are controlled at all levels, but various problems are still inevitable. Today, let's talk about how the uneven corrugations on the pipe surface are generated and what methods can be used to avoid this topic.
Aluminum profile lean tube is an aluminum material produced by heating, melting and extruding aluminum rods. The cross-section has a cross-shaped vertical bidirectional positioning structure, with a hollow pipe in the middle. The wall thickness dimensions are 0.8mm, 1.0mm, 1.2mm, Varies from 2.0mm. It is necessary to use an aluminum extrusion die during extrusion and follow the prescribed production operation process. During the extrusion process, uneven ripples appear on the surface of the lean tube profile due to the following problems.
