Quality control of wax mold assembly and module etching and cleaning
In the process of wax mold assembly in precision casting companies, the following phenomena often occur: the operator chooses the wrong die head, the wax mold welding distance is incorrect, the wax mold arrangement is wrong, the wax drips, and there are welds, etc., which are greatly affected The production rate of castings and the pass rate of one-time delivery are calculated.
Module etching and cleaning are mainly degreasing to improve the wettability of the module and facilitate coating. Therefore, on the one hand, it is necessary to record and control the preparation and use times of the etching solution; on the other hand, it is necessary to inspect the modules by batch to observe whether the silica sol (0.5% of the volume of wetting agent) completely wets the module.
Precision casting enterprises should strengthen the quality control of the above two points.
