Advanced forming tech-KTM production line from Korea
According to w-bending molding methods, it is able to make the protuberant precision of weld seams stable. So it can achieve superior quality of weld seams and precision of burrs.HFW system is automatically adjusted.KTM can produce the high or low D/T proportion products easily.
We use continuous roller hearth annealing oven imported from Korea,which are very efficient and productive.No oxidation on the surface of tubes after annealing,thus leads to the good quality of surface after cold drawn
Triple draw bench from Korea
Triple draw bench is the most advanced cold drawn equipment in the world.It can improve the efficiency,reduce material consumption,and lead to more reliable product.This equipment ensure the precise dimension and good internal surface roughness Ra ≤0.4μm.
