Continuous Screw Flights

Continuous Cold Rolled Screw Flights

Continuous Cold Rolled Screw FlightsFEATURES

  • High accuracy, low material wastage
  • Smooth surface finish and good rigidity, easy to weld and assemble



Carbon Steel



Any screw flight with size coming in the range of the following table can be made.

5.0 28 500 165 0.8-1.3 4.0
6.0 40 500 165 0.8-1.2 4.0








When the inner diameter is within the range of Min. +5mm, then the max. O.D. should not exceed the triple of I.D.

Minimum order quality of 15 tonnes exists for custom manufactured Continuous Screw Flights if the thickness required is not listed in above chat.


Continuous Equal Thickness Screw Flight


·Continuous equal thickness is another proprietary process patented and developed by our own in-house engineers with the purpose of overcoming problems like difficult forming, material wastage for small lot production.
·Continuous formed pitch construction with consistent cross sectional thickness between inner and outer edges, high precision, high output and high material usage.
·Manufactured in the same fashion as the screws manufactured by continuous cold rolled forming methods with the difference being consistent material thickness from inner to outer edge of the screw flight.


Screw Flights

The largest and professional screw flight manufacturer, with patents for spiral manufacturing process.

Backed with three manufacturing technology to produce the different types including Continuous Cold Roller Screw Flight, Sectional Screw Flight and Continuous Equal Thickness Screw Flight which almost meet all the market demand on the types and sizes.

Equipped with 23 screw flight forming machines, we have an annual production capacity up to 7000 tons.
