Screw flight forming machines are divided into single-blade and continuous types. They process steel strips or metal plates into continuous or single spiral blades, which are widely used in industries such as mining, environmental protection, chemical industry, and grain storage.
Single-blade spiral blade forming machines can process thicknesses from 8mm to 30mm. Continuous type machines can process thicknesses from 2-6mm and sheet diameters from 15-150mm.
What Is a Screw Flight Forming Machine?
The screw flight former machine is specially designed to produce spiral flights for screw conveyors. During operation, the steel strip is placed into the forming area, and the machine gradually bends and shapes the material into a continuous or individual spiral flight.
The forming process ensures uniform pitch, smooth shape, and good dimensional accuracy. This equipment is widely used by screw conveyor manufacturers, machinery factories, and industries that require customized spiral flight production.
Applications of Screw Conveyor Blade Forming Machines
- Agricultural Machinery: Manufacture helical blades for conveying materials such as grains and feed.
- Environmental Protection Machinery: Manufacture helical blades for waste treatment and sludge conveying.
- Mining Equipment: Manufacture high-efficiency conveying blades for materials such as ores and coal.
- Chemical Industry: Manufacture customized helical blades for handling chemical materials.
- Фармацевтическая промышленность.: Meet the needs of material mixing and transportation in pharmaceutical production.

The performance of the auger blade forming machine
- Single sheet metal is cold-rolled into fixed-pitch or variable-pitch helical blades in a single operation, eliminating the need for welding. The finished product boasts higher strength and a smoother surface.
- It supports carbon steel (Q235, Q345), stainless steel (304, 316L), and high-hardness wear-resistant plates (such as NM360/400/500, Hardox 450/500) with thicknesses ranging from 2-12mm.
- By changing the mold, materials with different hardness (such as 30mm carbon steel and 8mm wear-resistant plate) can achieve the same inner diameter, outer diameter and pitch.
Automatic screw flight forming machine advantages
- Compared to traditional segmented welded blades, the finished helical blades have higher overall strength, better wear resistance, and superior dynamic balance.
- Compared to traditional segmented cutting and welding processes, material consumption can be reduced by 8-12%.
- Each blade takes only 1-3 minutes to form (depending on size), significantly increasing production capacity.
- Operation is simple; new operators can master the operation process within 30 minutes.
