This pipe machine, in the ring type machine which represents today's international and domestic. This core components (pumps, valves, seals, etc.) are imported from abroad. In machine design, material selection process is heavily in innovation and exploration: the first is to eliminate the shrink tube axial displacement, facilitates user operations; second, to increase the amount of divergent to ± 38mm, can withhold various non-standard elbows, flanges, etc, once the withholding of 1 inch and a half (φ 38 ) layer of steel wire and hose. In addition die used rail tank design, mold eight gaps evenly consistent with overall working inside the mould guns (for matching), you can implement a one-time die replacement, foreign persons tribute!
