Tube Rolling Machine Manufacturer
Zhuoran tube end forming machines reshape tube ends to meet requirements for connection, assembly, sealing, and downstream manufacturing processes.
Models such as the TM40NC, TM60NC, TM80NC, and TM120NC accommodate a range of tube diameters and forming specifications. Leveraging hydraulic forming technology, microprocessor control systems, and custom tooling, Zhuoran delivers tailored tube end forming solutions based on your specific part drawings and production needs.
Process Overview
What Is Tube End Forming?
Tube end forming is a metal-forming process that changes the geometry of a tube end without removing the entire end section.
The process can be used to create an expanded end, reduced end, bead, flare, stepped profile, angled profile or another customized shape required by the final assembly.
Tube end forming is different from pipe chamfering. Chamfering mainly modifies the edge of a tube, while end forming changes the functional geometry of the tube end.

Tube End Forming Operations for Different Profiles
Reducing
Reducing decreases the tube-end diameter for nested connections, diameter transitions or pipe insertion.
Beading
Beading creates a raised ring or bead for positioning, retention or sealing-related applications.
Flaring
Flaring forms an expanded or conical end for connection, sealing or downstream assembly.
Flanging
Flanging creates an outward flange for welding bases, gasket mounting surfaces or connection interfaces.
Custom Forming
Custom tooling can be evaluated for square, angled, V-shaped, offset, elbow-style and other non-standard tube-end profiles.
The actual forming sequence, tooling design and number of stations should be confirmed from the part drawing or physical sample.

Copper and Aluminum Tube Forming
Controlled Forming for Copper and Aluminum Tubes
Copper and aluminum tubes require careful control of forming force, speed, lubrication and tooling surface condition.
These softer materials may be sensitive to surface scoring, sticking, cracking and dimensional distortion during end forming.
- Controlled forming force
- Suitable forming speed
- Polished tooling surfaces
- Material-specific lubrication
- Surface inspection after forming
- Sample validation before production release
Complete Tube Processing
Integrate Tube End Forming into a Complete Production Line
Zhuoran can evaluate complete tube-processing solutions rather than supplying only one standalone machine.
Depending on the production flow, a tube end forming machine can be integrated with cutting, bending, chamfering, feeding, unloading and conveying equipment.
- Automatic tube loading
- Pipe cutting machine integration
- CNC or NC pipe bending integration
- Pipe chamfering integration
- Automatic unloading
- Material transfer and conveying
- Production-line layout planning
Precision and Validation
Tube End Forming Accuracy Should Be Verified by the Actual Part
Zhuoran can provide different forming configurations according to the required precision, material and production method.
Hydraulic Standard Configuration
Reference positioning accuracy: ±0.1 mm.
Servo Precision Configuration
Reference positioning accuracy: ±0.02 mm.
Sample Verification
Final forming accuracy should be confirmed through the actual tube, tooling and inspection method.
- Tube-end diameter
- Forming depth
- Concentricity
- Flare angle
- End profile geometry
- Surface condition
- Cracks, wrinkles or local deformation
- Assembly and connection fit
Final forming accuracy depends on tube material, wall thickness, tooling design, machine configuration, forming sequence and inspection method. Sample validation is recommended before production release.
Automotive Application Case
Automotive Tube End Forming Case
01
Production Situation
An automotive piping plant was processing carbon-steel and stainless-steel brake and fuel-line fittings in the approximate range of Ø8–25 mm.
02
Original Challenge
Separate machines were used for reducing, expanding and flaring. Repeated transfers increased the risk of surface damage, inconsistent positioning and rework.
03
Reported Result
The project reported a yield rate of 99.3%, processing time reduced from 28 seconds to 12 seconds and an approximate payback period of 8 months.
These results are project-specific and should not be treated as a guaranteed result for every application. Actual performance depends on material, tooling, automation scope, production volume and inspection requirements.
Automation Options
From Standalone End Forming to Automated Production Lines
Standalone Machine
A standalone tube end forming machine can be used for manual or semi-automatic production and is suitable for flexible production environments.
Automated Line
Automatic loading, unloading, conveying and integration with other tube-processing equipment can be evaluated for higher-volume production.
Automatic feeding and unloading typically increase equipment investment by approximately 20%–35%, depending on the automation scope and line configuration.
Automation should be evaluated against production volume, labor requirements, changeover frequency, product variation, floor layout and expected payback period.
