模具設備:采用直角多層螺旋分流式結構,此結構減小了擠出壓力,塑化均勻,高速擠出成型穩定,管材各項指標均達到我國的標準。結構為新型烯烴類組合式,管材壁厚均勻,內外平滑,無凹凸或疤痕,定型更穩定,尺更準確. Die: the right angle multi-layer spiral split structure is adopted, which reduces the extrusion pressure, plasticizes evenly, and the high-speed extrusion molding is stable. All indexes of the pipe meet the national standards. The structure is a new type of olefin combination type, with uniform w
