High-speed fully automatic spiral center tube making machine designed for high-efficiency filter core production. Features a 3 kW main motor, 20–35 pcs/min capacity, and adjustable 30–75 mm tube diameter. It completes embossing, perforation, and spiral rolling in a single continuous process. After fabricating the supportive metal cores, the pleated media from our [Automatic Glass Fiber Filter Pleating & Gluing Machine](/glass-fiber-filter-pleating-gluing-machine) can be wrapped around them to complete the high-performance filter assembly.
This high-speed Fully Automatic Spiral Center Tube Making Machine is a specialized piece of equipment engineered to manufacture supportive metal inner cores (spiral tubes) for oil filters, fuel filters, hydraulic filters, and PP meltblown filter elements. It integrates metal strip uncoiling, continuous perforation, embossing, edge folding, and spiral tube forming into a single, automated workflow.
By producing robust and uniform metal cores, this machine ensures that the final filter cartridges can withstand immense pressure differentials without collapsing. It is an indispensable asset for filter manufacturers requiring high-volume, continuous output with tight structural tolerances and minimum manual labor.

Key Features & Mechanical Advantages
1. All-in-One Automated Production
The machine completes the uncoiling of tin-plated or galvanized steel strips, sheet perforation (or louvering), embossing, edge interlocking, and spiral rolling in a single continuous process. This eliminates the need for multiple manual stations, drastically reducing labor costs and human error.
2. Infinitely Adjustable Cutting Length
Controlled by a precise pneumatic cutting mechanism, the machine slices the continuous spiral tube to the exact preset length. The cut is made on-the-fly without stopping the core-forming process, ensuring a perfectly smooth, burr-free end cap surface for easy downstream filter assembly.
3. Interchangeable Diameter Molds
Capable of producing center tubes within a Φ30 to Φ75 mm diameter range. Changing from one diameter specification to another is accomplished simply by swapping the forming molds and adjusting the feed angle, completing the changeover in under 10 minutes.
4. Heavy-Duty Steel Frame & Components
Built with a rigid, vibration-damping steel frame, the forming rollers are CNC-ground from hardened tool steel and chromium-plated. This guarantees thousands of hours of non-deformation forming, even when running heavy galvanized steel strips.
Applications & Industrial Uses
This automatic spiral tube coiling machine is widely deployed in production lines for:
Spin-On Oil Filters: Producing the supportive perforated inner cores for automotive and truck oil filters.
Fuel & Water Separators: Forming heavy-duty rust-resistant cores for diesel fuel filtration systems.
PP Meltblown Filter Elements: Manufacturing the internal structural support tubes required for high-pressure water filter cartridges.
Hydraulic Filter Elements: Creating rugged, high-strength inner mesh tubes designed to survive extreme pressure differentials.

Frequently Asked Questions
A: The machine is optimized for tin-plated steel strips or galvanized steel strips with a thickness of 0.25 to 0.32 mm and a standard strip width of 45 mm. These raw materials ensure excellent corrosion resistance and optimal forming stiffness.
A: Yes, the length of the center tube is infinitely adjustable on-the-fly via the pneumatic cutting control. The tube diameter can be configured from Φ30 to Φ75 mm by using different interchangeable molds. Custom molds for larger or smaller diameters can be engineered upon request.
A: Yes. The machine is equipped with an integrated perforation device that punctures either standard circular holes or louvered holes into the metal strip before it is rolled into a spiral shape, ensuring optimal fluid flow while maintaining core stiffness.
