Extrusion barrel temperature will affect the quality of the choice of unreasonable manufacturer of aluminum tee welds, for thick-walled tube extrusion temperature profiles proposal 440-460 ℃, and for thin-walled sections and split down the hole is too large, it is recommended selection of 400-420 ℃ aluminum tee supply manufacturers, on the other hand, squeeze tube is not clean, more coproduct scale or squeeze tube is deformed as the drum, as well as squeeze tube and squeeze the pad gap is too large, these all affect weld quality. Steel molding manufacturing or storage during transport links and good quality aluminum Which in rolling, the surface will rust. Because of the corrosion layer loose structure is not strong adhesion to the substrate, and can be composed of iron oxide and aluminum primary batteries, further promote aluminum corrosion, the coating will soon be destroyed, so it must be in addition to the net before painting. Product is commonly used pickling rust, it does not make aluminum workpiece deformation, corrosion every corner can be cleaned, rust fast, relatively low-cost aluminum tee suppliers, aluminum tee, rolls of aluminum Aluminum Industry Co., Ltd. is provided by Jinan rolls. Jinan Heshun Aluminum Co. (www.jnhsly.com) strong, credible, in Jinan, Shandong aluminum products industry has accumulated a large number of loyal customers. The company better work attitude and constantly improving innovative ideas will lead rolls in aluminum and you hand into the brilliant, for a better future!
