Applications of spiral blade forming machine
- Agricultural machinery: manufacture spiral blades for conveying materials such as grains and feed.
- Environmental protection machinery: manufacture spiral blades for waste disposal and sludge conveyance.
- Mining equipment: manufacture high-efficiency conveying blades suitable for materials such as ore and coal.
- Chemical industry: manufacture customized spiral blades for chemical material handling.
- Pharmaceutical industry: meet the needs of material mixing and conveyance in pharmaceutical production.
screw flight rolling machine working principle
The spiral blade forming machine pushes raw materials into a special mold through a mechanical or hydraulic system. Under the guidance of the mold and the application of pressure, the material undergoes plastic deformation and gradually forms into spiral blades.
This process ensures that the blades are dimensionally accurate and structurally uniform, meeting production requirements for different diameters, blade spacing, and specifications, and providing high-quality finished products suitable for various industrial conveying and mixing applications.
Two types of screw conveyor blade machine
To meet the needs of different industries and production volumes, we offer two models of spiral blade forming machines: single-piece spiral blade forming machines and continuous spiral forming machines.
Each model has its unique features and is suitable for customized and high-volume blade production scenarios. The following sections will introduce the features and applications of these two models to help you choose the most suitable production equipment based on your actual needs.
single piece spiral flight forming machine
The single-piece spiral blade forming machine is specifically designed for cold-forming solid metal plates into continuous, weld-free spiral blades. It is widely used in applications such as spiral conveyors, drilling equipment, agricultural machinery, feed processing, cement, and grain storage.
This equipment supports the forming of blades with an outer diameter of 400–1400 mm, an inner hole diameter of ≥12 mm or ≥20 mm, and a pitch of 50–800 mm, meeting various specification requirements, and is particularly suitable for customized production of medium to large sizes.
Core Performance
- A single piece of metal sheet can be cold-rolled into fixed-pitch or variable-pitch spiral blades in a single process, eliminating the need for welding. This results in higher strength and a smoother surface finish in the finished product.
- Supports carbon steel (Q235, Q345), stainless steel (304, 316L), and high-hardness wear-resistant plates (e.g., NM360/400/500, Hardox 450/500) with thicknesses ranging from 2–12 mm.
- By changing the die, materials of different hardnesses (e.g., 30 mm carbon steel and 8 mm wear-resistant plate) can achieve the same inner diameter, outer diameter, and pitch.
Equipment Advantages
- The finished spiral blades have higher overall strength, superior wear resistance, and better dynamic balance performance compared to traditional segmented welded blades.
- Compared to the traditional sector cutting + welding process, material consumption can be reduced by 8–12%.
- Each blade takes only 1–3 minutes to form (depending on size), significantly increasing production capacity.
- Easy to operate; new operators can master the process in 30 minutes.

continuous spiral blade welding machine
The continuous spiral blade forming machine can continuously process long strips of steel into spiral blades of any length without welds.
It is particularly suitable for high-volume production scenarios and is widely used in feed conveying spirals, food processing spirals, small conveying devices, pharmaceutical extrusion equipment, 3D printing filament drivers, and precision metering pumps.
This spiral blade forming machine supports processing steel strip materials with thicknesses of 2–6 mm and widths of 15–150 mm (including carbon steel, stainless steel, spring steel, aluminum, brass, etc.).
The outer diameter of the formed spiral blades can reach approximately 20–300 mm, with an inner diameter of ≥8 mm. The pitch range can be freely adjusted during operation to accommodate various specification requirements.
machine Features
- Suitable for steel strips of various materials and sizes, with forming dimensions ranging from small to medium diameters.
- Equipped with a PLC + HMI system, supporting recipe storage and parameter recall, with pitch error less than 1 mm/m.
- Integrated uncoiling → straightening → servo feeding → forming → cold saw flying cut, continuous output without interruption.
- Core shaft replacement takes only 5–10 minutes, significantly reducing changeover time.
Equipment highlights
- Improved fatigue life of spiral blades, smoother surface, easy to clean, suitable for the food and pharmaceutical industries.
- Small blades can reach speeds of up to 30 meters per minute, significantly improving production efficiency.
- The continuous forming process results in extremely low material loss, with a scrap rate of less than 1%.
- The equipment occupies only approximately 2 meters × 1 meter of floor space, making it suitable for use in modular production lines or small workshops.
