flighting

The sectional screw flight presents a single pitch construction, the outer diameter, inner diameter and the pitch can accurately meet the size required once forming is completed. Now the technology is used in forming the screw flight made by carbon steel, wear resistant steel and stainless steel materials. The production range is mainly the outer diameter under 1200mm, the inner diameter more than 40mm, the pitch size less than 900mm and the thickness under 25mm. Different types and forms are available like equal diameter / variational diameter, equal pitch / variational pitch and inner hole with supporting lugs, etc.. Compared with continuous rolled forming technology, it has the advantages of higher yield, higher precision of forming, higher eligible rate, small quantity order requirement and various supply demand can be met. It particularly applies to the production of big thickness, big size flight made by wearable steel or stainless steel.
