Grinding Ball is very competitive now in China, with High-Quality Products. the raw materials are selected from high quality special steel produced by large and well-known national steel mills, and the raw materials are strictly tested for quality, such as hardness, raw material composition, ultrasonic inspection, etc.
Our company have professional and technical personnel and quality control team, the main testing equipment has the ultrasonic flaw detector, Germany imports spectrum analyzer, metal cutting core-pulling machine, metallographic microscope, rockwell hardness tester, impact tester, drop test machine, hand-held infrared thermometer, vernier caliper, etc., quality control and inspection of steel ball.
Strict quality control system, quality traceability management is implemented in the production process. Each order has a corresponding traceability number. According to the number, the whole process information of raw material suppliers, process cards, production equipment, production personnel, quality control personnel and so on can be queried.
