Causes and solutions for surface damage of aluminum profiles

The main reason for surface damage of aluminum profile ① There are impurities or segregation of aluminu ingot components on the surface of the ingot. When there are a lot of segregation floats on the surface of the ingot and the ingot has not been homogenized or the homogenization treatment effect is not good, there are a certain number of hard metal particles in the ingot, and when the metal flows through the working belt during the extrusion process , These segregation floats or hard metal particles adhere to the surface of the working belt or cause damage to the working belt, and eventually scratch the surface of the profile; ②There are sundries on the mold cavity or working belt, and the hardness of the working belt of the mold is low, so that the surface of the working belt is injured during extrusion and the profile is scratched; ③There are bare metal or graphite strips on the discharge track or swing bed with hard inclusions, which will scratch the surface of the profile when it

Extrusion Heat Sinks & Profiles for Cost Effective Cooling Solutions Foshan Liangyin offers a wide variety of ultra-performance straight fin, slant fin, and pin fin extruded heat sinks. These high aspect ratio heat sinks are ideal for applications where there is adequate airflow to take optimum advantage from these designs.  We  also offers an array of heat sink extrusion profiles with different thermal performances, fin-to-fin spacing, lengths and heights.  Extrusion profiles  enable engineers to either select or start their design from a pre-tooled extrusion profile for the cooling solution.  When selecting or designing a  Heat sink , the following factors must be considered. Material The most common  Heat sink  material is aluminum alloy. Aluminum alloy 1050A has one of the higher thermal conductivity values, 229 W/m-K, but has softer mechanical properties. Aluminum alloys 6060 and 6063 are commonly used and have thermal conductivity values of 166 and 201 W/m-K, respectively. th
