1.模具上优化滑块之间的结合面并定期保养（5W件/次）；2.工艺上改进

1. Optimize the joint surface between the sliders on the mold and maintain it regularly (5W pieces/time); <br>2. Improve the process, increase the vibration grinding process after the peripheral burrs are polished, use special-sized abrasives, time 30min; <br>3. Abrasive tool The maintenance requirements and process improvements are updated synchronously "operation guidance documents"; <br>4. Ensure the inspection workbench and working environment, ensure sufficient light, relevant QC to do regular training based on customer feedback; <br>5. Develop "surface defect quality warning"

1. Optimize the combination surface between the sliders on the mold and maintain regularly (5W pieces/time);<br>2. Process improvement, peripheral burr polishing after the increase of the seismic grinding process, the use of special size abrasives, time 30min;<br>3. The maintenance requirements and process improvement of the abrasives update the "operation guidance document" simultaneously;<br>4. To ensure that the inspection of the workbench and working environment, to ensure adequate lighting, the relevant QC according to customer feedback regularly do a good job of training;<br>5. Develop ingested the Quality Warning for Surface Defects

1. Optimize the joint surface between sliders on the mold and maintain it regularly (5W pieces / time);<br>2. The process is improved. After the peripheral burr is polished, the vibration grinding process is added. The special size abrasive is used for 30min;<br>3. The maintenance requirements and process improvement of abrasive tools shall update the operation guidance document simultaneously;<br>4. Ensure the working platform and working environment for inspection, ensure sufficient light, and relevant QC shall conduct regular training according to customer feedback;<br>5. Formulate surface defect quality warning<br>
