Improvement Method of Sand Flushing for Shell Mold of Precision Casting

Through the weekly quality improvement meeting on Wednesday, precision casting manufacturer Shengyu metal continues to pay attention to the quality situation. The company always adheres to the business philosophy of quality first. Recently, the quality data reflect the increase in the proportion of poor sand washing products in production.

The production department led the audit department to assist in the follow-up inspection. The production department listed the possible sand washing points in the production process one by one through the 8D analysis method. The audit department went deep into the site to investigate one by one according to the control points listed by the production department. Finally, the main cause of poor sand washing was found in the shell mold link, and the shell mold was inspected by sampling, 30% of anomalies were found.

The production department quickly formulated corresponding corrective and preventive measures:

1. Clean the hard blocks on the iron sheet of the gate cup;

2. Increase the cleaning times of filter screen in dewaxing link;

3. Upgrade the method of wiping gate cup in smelting process.

Two weeks after the implementation of the measures, the quality of shell mold has been sampled again, which has been reduced from 30% to 3%. Quality is the cornerstone of the company's production and development and the lifeline of the company.
