In the case of everyone using aluminum profiles extrusion products equipment, many users will often encounter false connectors on the surface, scratches on the surface, mechanical equipment texture, black stripes on the surface, tactile bumps on the surface, and serious welding. After the surface is solved, the aluminum profile has a black band or a serious color cast, which damages the product, resulting in irreparable damage. If you have problems in these aspects, let's take a look together.
In the process of processing, we often encounter problems such as false connectors on the surface, scratches on the surface, texture of mechanical equipment, black stripes on the surface, convex and concave touch on the surface, serious welding and other problems. Damage the product, resulting in irreparable damage. The low welding force is because the extrusion force is too low, and the factors that cause the low extrusion force include the elements on the abrasive tool and the processing technology.
Extrusion temperature and extrusion rate The high temperature of the aluminum ingot is beneficial to the external diffusion and fusion of the metal, but it also aggravates the phenomenon of metal bonding abrasives. In addition, the high temperature also causes the crystal growth and development rate of the metal mechanism to accelerate. , thus making the welding mechanism stout. If the extrusion rate is too high, the deformation work of the metal expands, and the temperature of the metal rises greatly. In addition, if the extrusion temperature is too high, the extrusion force will be reduced, thus reducing the welding force. In fact, when graphite products are used as feed slips, aluminum profiles extrusion products are prone to black bands after air oxidation on the side that touches high-purity graphite.
