Metal Spinning

Metal Spinning

Metal spinning, also known as spin forming, metal forming or metal turning is a cold work metal forming process which forms metals into axially symmetric parts. The process begins with flat sheet metal cut into a disk and is then formed ove......

Shear Forming

Shear Forming

Shear spinning, also known as forced spinning of conical components, involves mounting and securing a sheet or conical blank onto a die. During spinning, the spinning roller, along with the workpiece and die, rotates, causing the workpiece ......

Expanding Spinning

Expanding Spinning

Expanding diameter spinning is a spinning forming method in which a hollow rotating body container or a tubular blank is increased in diameter (middle or end) by a spinning tool. The limitation of this method is mainly the material properti......

Flange Forming

Flange Forming

Double wheel spinning flanging is a technique used for creating flanges and shaping the bells of cylindrical products. This process involves securing the edge of cylindrical shaped items with two rollers as well as punching of flange holes.......

Wheel Rim Flow Forming

Wheel Rim Flow Forming

The fundamental principle of groove spinning forming lies in the transfer of metal volume, adhering to the principle of volume invariance in plastic deformation. Essentially, groove forming is achieved through material flow along the tube w......

Necking-in

Necking-in

Spinning seamless integral cylinders represent a novel process and product in the industry. These cylinders come in four main types: steel seamless gas cylinders, aluminum alloy gas cylinders, composite cylinders with steel inner walls, and......

Beading, Trimming, Flanging

Beading, Trimming, Flanging

The CNC spinning machine not only meets various spinning technology requirements but also incorporates auxiliary functions, enhancing its versatility. This multi-functional machine is capable of performing the following tasks:1. Beading – ......

Flow Forming

Flow Forming

Multi-Rollers technology: cylindrical deformation thinning spinning is a process for manufacturing thin-walled, elongated cylindrical components. This method involves spinning rollers pressing against a tube blank. The tube blank rotates in......
