Tube Reducing Machine ( OD Shrinking Forming )

Tube end reducing machines employ radial cold extrusion technology, utilizing tapered molds to apply pressure on metal tube ends for plastic deformation and precise diameter contraction. This technology primarily serves tube interconnection assembly, fluid control optimization, and end-structure reinforcement, effectively enhancing connection sealing and assembly efficiency. Common applications include furniture leg finishing, automotive exhaust pipe forming, and fitness equipment weight rod processing, achieving functional requirements while ensuring aesthetic treatment and safety protection ...

Tube Expanding Machine

Tube expanding machines operate on the radial expansion principle, utilizing hydraulic or mechanical drives to radially expand a mandrel inside the tube end, forcing the tube wall to undergo plastic deformation and create an interference fit with the tube sheet. Its core function is to achieve tight connections between tubes and tube sheets, ensuring sealing integrity and tensile strength while enhancing heat transfer efficiency by eliminating gaps. This technology is primarily applied in the manufacturing of heat exchangers, boilers, condensers, and other pressure vessels, serving as a critical process equipment for tube-to-tube sheet connections in power ...

Rotary Tube Tapering Machine

Tube tapering machines utilize spinning or extrusion forming technology to apply directional pressure on metal tube ends through rollers or molds, causing plastic deformation to create precision tapered surfaces. This process not only achieves industrial functions such as sealed connections and fluid optimization, but also creates elegant tapered finishes for consumer products like furniture legs. The formed components combine structural strength with aesthetic value, finding extensive applications in industrial fields including hydraulic system ports and aerospace pipeline connectors, as well as civilian products such as modern furniture legs and decorative columns ...

Tube End Sealing Machine / Pipe Flanging Machine

Tube end closing machines and tube flanging machines are two critical types of tube end forming equipment. The closing machine utilizes spinning or stamping technology to plastically deform the tube end, achieving complete closure and forming hemispherical or other end structures. It is primarily used in applications requiring sealing and safety protection, such as furniture legs and fitness equipment weight rods. The flanging machine employs a mandrel expansion process to form an annular lip on the tube end, enhancing connection strength by increasing the welding area and providing a mounting base for sealing elements. It is widely applied in scenarios demanding high-strength connections, such as automotive fuel lines and pressure vessel pipelines ...
