Many in the aluminum alloy casting industry friends know, production of high quality aluminum castings, the production process is very very much need to pay attention to. How can you say some skills in the process of casting, listen to the foundry! In order to ensure the quality of aluminum castings, at the start of the inspection of the casting must carry on the omni-directional carefully in advance, can not see in liquid aluminum alloy casting system orderly, steady flow, it is not easy to verify the separation and vortex formation conditions such as; At the same time also have to check the Angle area or dead zones; Check the project to be reckoned with in the changes and the diameter of the casting system, etc. In aluminum casting pressing steps, such as gas evolution of aluminum casting porosity have immediate harm, so in order to avoid similar phenomenon, the first to choose the dry mania, neat alloy material; Adjust smelting temperature, at the same time avoid overtemperature, completes the degassing is solved. Of course also to correctly choose casting process specifications, must choose order fill, so more conducive to cavity gas row qing; Direct sprue and runner have enough size, to facilitate stable liquid alloy swimming and have a chance to row out of gas. In addition, also want to choose good performance for aluminium casting coating and adjust the volume of brush. For aluminum casting, because the formation of every kind of faults from several different influencing factors, so in the practical manufacturing level according to the difficulty coefficient, Jane before they are complex to solve. For example at first clean aluminum casting casting mold parting surface, cavity, cylinder; Then is to improve coating and coating process; And increase the clamping force, improve casting aluminum alloy; Then adjust the technical parameters, have included injection force, injection rate, the filling time and duration, the mold casting temperature, mould temperature, etc. ; Finally is to determine the quality of aluminum alloy ingot, change the ratio of new material to back to the furnace charge, improving smelting process.
