High-precision Hydraulic Cold-drawing Machine

These High-Precision Hydraulic Cold-Drawing Machine can be used for the cold drawing processing for various types of low and medium carbon steel and low and medium alloy steel pipes and bars, featuring extensive applications. Our company designed the testing equipment at the beginning of the development of cold drawing machine (Year 1987), conducted a large amount of process tests, and mastered the basic principle of cold drawing process. The i rst complete cold drawing machine was developed by the technicians of our company.
