Buy the Most advanced Tube Necking Machine
CDOCAST state-of-the-art Tube Necking Machine is engineered to deliver unparalleled accuracy and efficiency in reducing the diameter of tube ends. Designed for demanding precious metal & industrial applications, this robust machine is the cornerstone for creating secure, leak-proof connections in tubing systems across diverse sectors.
This Tube Necking Machine is exclusively designed for precision necking processing of precious metal hollow tube ends (Ø2-12mm), including gold, silver, copper, etc. Utilizing cold forging technology, it reduces tube end diameters by 15%-30% to form standardized tapered lead-in ends. These precisely shaped ends directly interface with rolling mill grooves or drawing dies, effectively eliminating feeding jams and end deformation caused by the soft nature of precious metal thin-walled tubes. This ensures continuous, high-efficiency operation of subsequent rolling/drawing processes.
Tube necking machine is a device for processing metal tube ends. It achieves plastic deformation through radial compression, reducing tube diameter while increasing wall thickness. Its operating principle is based on foundational theories of metal plasticity: The hydraulic system actuates dies to apply radial pressure on the tube end, causing axial material flow that completes the necking formation.

1. Exceptional Precision & Consistency: Achieves tight tolerances on neck diameter, length, angle, and concentricity, critical for leak-proof fittings and assembly reliability. Batch-to-batch consistency is guaranteed.
2. Superior Surface Finish: Cold-forming process produces a smooth, work-hardened surface on the necked area, enhancing fatigue life and seal integrity. Minimizes the need for secondary finishing.
3. High Production Efficiency: Fast cycle times, easy setup (especially with quick-change tooling), and potential for automation integration (auto-load/unload) significantly boost throughput.
4. Zero Material Loss Processing: 99.8% material utilization via chip-free cold forming, Surface integrity maintained.
5. Versatility: Capable of necking a wide range of tube materials (gold, silver, copper, brass etc) and diameters (specify your typical range φ2-12mm) with appropriate tooling.
6. Reduced Secondary Operations: Produces a ready-to-assembly tube end, often eliminating the need for additional swaging, flaring (in some cases), or extensive cleaning.
7. Operator-Friendly: Intuitive controls, clear setup procedures, and accessible tooling changes minimize training time and operator error.
