The key to the quality control of the process after the quality inspection of precision castings includes the removal of pouring risers (laser cutting, grinding and polishing), shelling, welding repair, shot blasting and rust removal, fine polishing, shaping, heat treatment process, phosphating treatment, sand cleaning, and grinding Polishing, electrostatic spraying and chemical polishing process.
In fact, the process quality control is more complicated, which can better enable us to improve the quality control of each process. In some small and medium-sized precision casting companies in China, noise, dust, and safety production accidents are common in the back process.
There is also a point of special attention: this kind of common phenomenon in the production workshop of enterprises seriously affects the eyesight of the employees, the situation of insufficient internal light, the actual effect of judging work efficiency and product quality, and the setting of this kind of basic natural environment.
Therefore, precision casting companies must implement my country's ISO14000 and OHSAS18000 quality management system specifications.
Some precision casting companies have selected bar graphs, sorting methods, analysis methods, causality diagram analysis methods, and Plato and other statistical analysis methods to be used in the enterprises, so that they can analyze and implement the effect of the enterprises. Therefore, the precision casting enterprises should be established. The data analysis system is carried out using statistical techniques. However, the truthfulness, consistency, accuracy and timeliness of this data have not been reasonably controlled, and the analysis of this data has not been carried out, and certain effective measures have been taken to carry out reasonable Continuous improvement, data for data.
