Internal quality control and assurance

1、 All diffusion paddles must undergo cold and room temperature testing,

·New propeller samples must be subjected to thermal inspection one by one, and batch propellers should be sampled at a rate of 25% -30% per furnace.

2、 When the proportion of abnormal fractures occurs during thermal inspection, the sampling ratio for each furnace should be increased.

3、 Both cold and hot inspections require the retention of imaging data, including blade number and weight weighing

Process recording, recording of the entire cold and hot load process, temperature testing, etc. After each furnace inspection is completed, images are retained for future reference.
