Quality management of aluminum die casting die

(Summary description)It is very important to check the quality of products produced in a large number of production projects. Even if such an examination is made, the results of the examination can still not be 100% trusted. This is clear only through statistical investigation. In addition, once the quality such as the destructive strength of the casting is checked, it indicates that the casting cannot be used. Therefore, for such quality, statistical methods (such as sampling inspection) must be used to estimate the quality of all production batches and judge whether these castings are qualified. For the explanation of this statistical method, let the special statistics do it. Before the description of quality management, give a vivid example to illustrate. For example, shoot a target with an air gun, accurately aim the collimation of the air gun at the bull's-eye and fix it on the shooting platform, and shoot dozens of bullets at the bull's-eye. In this case, the bullets hit the target within a certain range. However, it is rare to hit at the same target position. After investigation, it is found that the life points are scattered in a wide range. This is the result of the change of wind and air resistance, the pulling of the shooting platform and other conditions. Then, two sets of bullets with different weights are used for the test. In this case, the hit center position of the bullet It varies with the cartridge group. The quality of mass-produced castings should be considered in the design stage, and the allowable deviation range should be determined. The allowable range reached is similar to the hit range of the above air gun handle. For mass production castings, if the quality error is small and concentrated near the bull's-eye, it is ideal. However, as in the case of air gun shooting, the quality of mass-produced die castings also changes with the change of production conditions; If the conditions change greatly, the error will be large. Therefore, the casting quality control often focuses on the various conditions required in the production process within the range near the target center, which is the quality management work.
