ZTF(FFX) Flexible Forming Tube Mill

ZTF is a forming technique developed by ZTZG in 2005 based on improvements on Japan FFX forming. It allows the shared-usage of rollers during break-down section when forming pipe, saving significant mold and labor cost while greatly improving production efficiency.  

Products Details

For ZTF, we divide forming section into breakdown section and fin-pass section. ZTF technology is used in breakdown section. Only one set of roller is needed to produce all round pipe within the range (weigh around 60% of the entire mill rollers). When producing different sized pipe, only change rollers during fin pass section & sizing section, therefore saving significant roller cost and increase productivity. The latest generation ZTF technique(ZTF4) allows fully automatic adjustment of roller position during break-down section with minimum to none need of manual adjustment, significantly improve productivity while reducing labor maintenance cost and risk of hazard. The control system utilizes close-loop servo control to assure the accuracy and stability of roller positions.

High Efficiency

Line speed can be up to 120m/min.

Low Wastage

Low unit wastage and low production cost.

High Accuracy

Diameter error is only 0.5/100 of the pipe OD.
