Shuliy’s screw flight forming machine is designed to form steel plates or strips into spiral flights for screw conveyors, augers, agricultural machinery, material handling equipment, and other industrial applications. We offer two main types: single-piece spiral flight forming machines and continuous spiral blade forming machines.
The single-piece models cover processing diameters from approximately 400–1400 mm and pitch ranges from 100–1500 mm, while the continuous models cover outer diameters from 40–800 mm and pitch ranges of 50–800 mm.
Depending on the model, the machines can process carbon steel, stainless steel, and wear-resistant plates with thicknesses from 2 mm to 30 mm. Similar single-flight and continuous-flight equipment is also commonly used for screw conveyor and auger flight production.
What Is a Screw Flight Forming Machine?
A screw blade forming machine is industrial equipment used to transform flat steel blanks or strips into helical screw flights. These flights are then assembled with a central shaft to make screw conveyors, augers, and other spiral conveying components.
The finished flight can be specified according to:
- Outer diameter
- Inner diameter
- Flight pitch
- Plate thickness
- Material
- Flight length
- Left-hand or right-hand direction, where supported
Unlike manually bending or welding individual pieces, mechanical forming provides a more controlled way to produce repeatable spiral geometry. Screw flights are commonly used as the flighting component of screw conveyor systems.
Two Types of Screw Blade Forming Machines
Different production requirements call for different forming methods. Our equipment can be divided into:
- Single-Piece Spiral Flight Forming Machine
- Continuous Spiral Flight Forming Machine
The two types differ mainly in their raw material form, flight size range, thickness capability, and production application.
Single-Piece Spiral Flight Forming Machine
The single-piece spiral flight forming machine forms individual circular steel blanks into spiral flights. It is particularly suitable when customers need large-diameter, thick, customized, or heavy-duty screw flights.
The available models cover a wide range of specifications. The 250-12 model supports carbon steel up to 12 mm, while the larger 350-25 and 800-25 models can process carbon steel up to 25 mm. Stainless steel and wear-resistant plate capacities vary by model.
Main Features of Auger Flight Making Machine
- Wide flight size range. The five models cover different flight diameters and pitches, allowing users to select equipment according to their screw conveyor requirements.
- Suitable for thick steel plates. Depending on the model, maximum carbon steel thickness ranges from 12 mm to 30 mm, while stainless steel capacity ranges from 10 mm to 20 mm.
- Suitable for heavy-duty applications. The ability to process thicker carbon steel and wear-resistant plates makes this type suitable for demanding conveying and agricultural machinery applications.
- Flexible pitch range. Different models support pitch ranges from 100–500 mm to 200–1500 mm, providing options for different screw conveyor designs.
- High-power configuration. Machine power ranges from 4 kW to 11 kW, with the larger 800-25 model using 11 kW.

Continuous Spiral Flight Forming Machine
The continuous spiral flight forming machine is designed for continuously forming narrow steel strips into spiral flights. Compared with the single-piece type, it is more suitable for continuous production of smaller and medium-sized flights.
The supplied models cover outer diameters from 40 mm to 800 mm, inner diameters from 8 mm to 600 mm, material thicknesses from 2–4 mm or 2–6 mm, and pitch ranges of 50–800 mm.
Continuous flight forming is widely associated with producing seamless, one-piece helicoid flights from steel strip for screw conveyors.

Single-Piece vs. Continuous Screw Flight Forming Machine
Choosing between the two types depends mainly on the required flight size, material thickness, and production method.
| รายการ | Single-Piece Type | Continuous Type |
|---|---|---|
| Raw Material | Circular steel blanks | Steel strips |
| Flight Type | Individual spiral flights | Continuous spiral flights |
| Typical Diameter | 400–1400 mm depending on model | 40–800 mm depending on model |
| Material Thickness | 2–30 mm depending on material | 2–6 mm |
| Maximum Pitch | Up to 1500 mm | Up to 800 mm |
| Best For | Large, thick, customized flights | Continuous production |
| Heavy-Duty Flights | Suitable | More limited |
| Small/Medium Flights | Suitable depending on model | Particularly suitable |
| Production Method | Individual forming | Continuous forming |
The supplied specifications show that the single-piece type provides a wider thickness and pitch range, while the continuous type focuses on strip-based, continuous production. Comparable industry equipment also distinguishes single-flight forming from continuous auger flight production based on these production requirements.
How to Choose the Right Screw Flight Forming Machine?
Before purchasing a screw auger flight forming machine, customers should provide several key parameters.
1. Flight Outer Diameter
For example:
- 300 mm
- 500 mm
- 700 mm
- 800 mm
- 1000 mm
The required diameter determines which machine model is suitable.
2. Inner Diameter
The inner diameter needs to match the screw conveyor shaft or pipe.
3. Flight Pitch
Pitch affects the geometry and conveying characteristics of the screw flight. The supplied machines cover pitch ranges from 50 mm to 1500 mm, depending on type and model.
4. Material
Tell us whether you plan to process:
- Carbon steel
- Stainless steel
- Wear-resistant plate
Material type is especially important when selecting the single-piece machine because the maximum thickness varies significantly by material.
5. Plate or Strip Thickness
This is one of the most important selection parameters.
For example, the single-piece models can process carbon steel from 12 mm up to 30 mm, depending on the model, while the continuous models are designed for 2–6 mm material.
6. Production Requirement
For customers producing a large number of small or medium flights continuously, the continuous type may match the production process. For customized, large-diameter, or thick flights, the single-piece type provides broader size and thickness options.
