The alloy used for the production of extruded aluminum profiles, customized aluminum profiles, special-shaped aluminum profiles, and special-shaped aluminum profiles must have good thermal conductivity. The commonly used aluminum alloys include 6063, 6061, etc. Currently, 6063 aluminum alloy is widely used. Because it has good thermal conductivity and good mechanical properties. Aluminum profile production, customized aluminum profiles, profiles, profiles, and profiles ensure the quality of aluminum extruded radiators. We should start from the following aspects: the quality of aluminum bars should strictly control the alloy composition of the aluminum bars, and the aluminum bars should be fully homogenized to make the structure and properties uniform. The surface of the aluminum rod must be smooth, free of segregation and sand particles.

Aluminum profile production, customized aluminum profiles, profiles, profiles, and the ends of profiles should be flat rather than cut into steps. The mold requirements are due to the aluminum radiator having many fins. They will bear a lot of pressure during the squeezing process. Each fin must be very sturdy and resilient. So the quality of mold steel must be reliable. H13 tool steel is generally used. Mold heat treatment is very important. Aluminum profile production, customized aluminum profiles, irregular profiles, irregular aluminum profiles, irregular aluminum profiles require vacuum heating quenching, and high-pressure pure nitrogen quenching is preferred. This can ensure the uniformity of the performance of each part of the mold after quenching. After quenching, three rounds of tempering should be used.

Aluminum profile production, customized aluminum profiles, irregular profiles, irregular aluminum profiles, irregular aluminum profiles ensure that the mold hardness has sufficient toughness under the premise of HRC48-52. This is an important condition to prevent wing breakage. To prevent the fins from breaking, the compression pressure should be minimized as much as possible. The extrusion force is related to the length of the aluminum rod, the deformation resistance of the alloy, and the degree of deformation. Aluminum profile production, customized aluminum profiles, special-shaped profiles, special-shaped aluminum profiles, so the length of the casting rod should not be too long, about 0.6-0.85 times the normal length. Suitable for aluminum heat sink cross-sections with complex shapes: In addition to shortening the length of the casting rod, pure aluminum short castings are considered for the first extrusion test. After the successful extrusion test, ordinary cast rods will be used for extrusion production.

Uniform annealing of aluminum bars can not only homogenize the microstructure and properties. It can also improve extrusion performance and reduce extrusion pressure. Aluminum profile production, customized aluminum profiles, special-shaped aluminum profiles, special-shaped aluminum profiles, therefore, aluminum bars need to be uniformly annealed. The key to producing aluminum heat dissipation profiles through extrusion technology is the initial trial of extrusion molds. The operator should allow the main plunger to move forward at a low pressure of less than 8MPa. After each fin of the mold is evenly extruded. It can gradually increase pressure to accelerate the extrusion speed. Pay attention to the heating temperature of the tool/mold during extrusion processing. The temperature of the mold should be close to the temperature of the casting rod.
