Shear Forming

Shear Forming

Shear forming involves a round blank or preform being clamped between the spinning chuck and the tailstock and set in rotation. The round blank is formed parallel to the external contours of the tool by the shear forming rollers and applied to the tool. In contrast to the gradual metal spinning process, the material is applied in a single overflow: the metal is projected from one level to another.

The advantages of shear forming lie in the simplicity of the process. All conically tapered components can be made by shear forming in a single clamp. Since the process consists purely of material displacement, the change in the wall thickness of the finished part can be optimally calculated. While the shear forming roller moves parallel to the spinning chuck, the wall becomes increasingly thin in relation to the cone angle. The process results in tight tolerances and polishable surfaces.

FAQ's

Shearing forming uses much less material to produce the desired shape compared to other methods.

Shear forming is where you take a piece of material and form it over a tool thereby forming the final shape.

Almost any material can be shear formed.

Shear forming can form thick walled material into the desired shape whereby other forming processes are forming much thinner sheet metal type parts.

Shear forming has the ability to produce one piece structures instead of multiple piece welded together structures.

Yes, we make the parts to the customers required shape.

Any industry that has large complex shapes that typically would be made from multiple pieces could benefit from shear forming.

Typical shapes would include cones, nozzles, chambers, flanges etc.

All parts are laser scanned to ensure they conform dimensionally to the customer requirements.
