Shengyida custom heatsink manufacturer has been focusing on the R&D and production of aluminum heat sink for more than 10 years, providing customers with high-power custom aluminum metal heatsink, including custom aluminum tube heatsink, dense-tooth heat sink, copper-aluminum composite heat sink and so on. Next, Shengyida will briefly introduce the production process of aluminum metal heatsink.
1. For high-density tooth-to-tongue mold trials, the first aluminum rod must be a short aluminum rod or pure aluminum rod of 150200mm
2. Before trying the mold, the extrusion center must be adjusted so that the extrusion shaft, the ingot barrel and the outlet of the mold base are on the same center line.
3. In the trial and normal production process, the heating temperature of the aluminum rod should be ensured to be between 480520℃.
4. The mold heating temperature is controlled at about 480℃ according to the conventional mold temperature. The heat preservation time of flat molds with a diameter of 200mm or less shall not be less than 2 hours. If it is a split mold, the heat preservation time shall be more than 3 hours; In order to ensure the uniformity of the mold core temperature and the external temperature.
5. Before mold trial or production, the inner container of the ingot barrel must be cleaned with a cylinder cleaning gasket, and check whether the dry running of the extruder is normal.
6. When the mold is tried or the production is just started, the automatic gear of the extruder is turned off, and the switches of each section are returned to the zero position. Start slowly from the minimum pressure and discharge the material for about 35 minutes. The pressure is mainly controlled during the aluminum filling process. The pressure is controlled within 100Kg/cm2, and the ammeter data is within 23A. Generally, 80120Kg/cm2 can be discharged, and then it can be slowly accelerated. During normal production, the extrusion speed is subject to pressure less than 120Kg/cm2.
