Nanjing Dete Machine Tool Factory Tour
Located in the Hi-Tech Zone of Nanjing, Jiangsu Province, our 5,000 m² production facility is purpose-built for precision shredder blade manufacturing. From raw steel bars to finished, hardness-tested blades, every step is completed in-house under strict quality control.
Below is an overview of our production workshop, key equipment and manufacturing capabilities.
Factory Overview
20+ CNC lathes and machining centers with ±0.02mm positioning accuracy for precise blade blank shaping and profile machining.
Vacuum Heat Treatment
4 vacuum quenching furnaces with computer-controlled temperature curves ensure uniform hardness (HRC 55-62) throughout the blade body, preventing edge chipping.
Grinding & Inspection
8 surface grinders, profile grinders and a full metallurgical lab with HRC testers, ultrasonic flaw detectors and 3D measuring instruments.
