Quality Control
The company attaches great importance to the construction of management system, pursues stable product quality and good customer service
| Verify raw materials |
The raw material laboratory analyzes the composition and microstructure of main PDC materials such as micropowder and alloy, and strictly controls the quality of raw materials.

——————

| Production process inspection |
From the column blank to the finished product, each process is strictly implemented in accordance with the production process, and is inspected and judged according to quality standards to control the flow of unqualified products ——————
| Effect test of cobalt leaching |
Cobalt leaching is an important part of PDC performance improvement. X-ray fluoroscopy equipment was used to check the consistency of PDC cobalt leaching effect to ensure the consistency of product application. ——————
| Production batch performance inspection |
By testing the wear rate, impact resistance and heat resistance of each batch of PDC products, batch quality confirmation of important performance indicators of PDC and monitoring of product performance fluctuations
——————
| Final inspection of finished products |
The final inspection of the finished product is the last control before leaving the factory. Through the product size, appearance, ultrasonic flaw detection results, X-ray cobalt leaching results, combined with the previous batch performance test, the batch quality inspection results of the product are finally formed. Eliminate the outflow of substandard products ——————
