What are the standards for quality inspection and testing of precision castings?

After quality inspection and testing of precision castings, the key to process quality control is removal of pouring risers (laser cutting, grinding), shelling, welding, shot blasting, fine grinding, shaping, heat treatment process, phosphating treatment, and sand cleaning , grinding and polishing, electrostatic spraying, chemical polishing process.

In fact, the quality control of the process is more complicated, which can better improve our quality control of each process. In some small and medium-sized precision casting enterprises in our country, post-processing general phenomena include noise, dust, and production accidents.

Another point that requires special attention is that this common phenomenon in enterprise production workshops has seriously affected employees' vision, insufficient internal light, work efficiency and product quality judgment, as well as the setting of this basic natural environment.

Therefore, precision casting companies need to implement ISO14000 and OHSAS18000 quality management system specifications in China.

Some precision casting companies use bar charts, sorting methods, analysis methods, cause-effect diagram analysis methods, Plato and other statistical analysis methods to apply to companies, which have analysis and implementation effects on companies. Therefore, precision casting companies should establish a system that applies statistical technology. Data analysis system. However, the authenticity, validity and consistency, accuracy and timeliness of these data have not been reasonably controlled, nor have these data been analyzed, and certain effective measures have been taken to conduct reasonable and continuous Improve.
