Features
The die frame utilizes a sealed water-cooling structure, with the left and right modules moving within a closed curve.
The die frame utilizes a gear-driven mechanism, offering advantages such as automatic wear compensation, smooth operation, low noise, long service life, and high synchronization.
The uniquely designed circulating water circuit provides high reliability and effective cooling. The water in the circuit minimizes impact force, enhancing the reliability of continuous pipe production and ensuring the quality of the pipe surface.
