Business Type: Trading Company
Nantong, Jiangsu, China
The largest and professional screw flight manufacturer with 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.WIDE A
Carbon Steel, Low Alloy Steel, Wear Resistant Steel, Stainless Steel, etc.
Any Screw flight with size coming in the range of the following table can be made.
P--Pitch, D--Do, d--ID, T--Thickness
|Ratio of Min.O.D||Min O.D.|
|60~100||30||480||1.0||Min O.D. = Pitch|
Customized x Ratio
·Continuous equal thickness is another proprietary process 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.
Any screw flight with size coming in the range of the following table can be made.
|Max. Band Width|
|Ratio of Pitch and|
I.D. and O.D.
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.
