Flow Forming Sheet Metal

Classification of basic sheet forming processes bending deep drawing shearing.

Flow forming sheet metal.

Sheet metal forming involves forming and cutting operations performed on metal sheets strips and coils. The surface area to volume ratio of the starting metal is relatively high. Chipless metal forming machinery and related machine tools metal spinning shear forming machines spinning lathes spinforming lathes flow forming machines flow forming lathes wheel forming machines rotary forging presses tube cylinder necking in closing machines trimming beading flanging lock seaming machines. Metal spinning and flow forming have noteworthy differences in the initial blank or preform used mainly because the final workpiece produced by each process has different requirements.

Steel technology has advanced to increasing the possibilities for this lower cost material flow forming sheet metal and wenzel metal spinning is interested in working with our customers to find the best way this very versatile material can work for you. For a full selection of special types of steel please visit our materials page. About 90 percent of spun parts can be formed by starting with a blank disk trimmed from standard commercial sheet metal. Once the material has been penetrated the polygonal shape of the screw forms a metric female thread.

3d cad files are converted into machine code which controls a machine to precisely cut and form the sheets into the final part. Sheet metal fabrication is the process of forming parts from a metal sheet by punching cutting stamping and bending. Flow forming is an incremental metal forming technique in which a disk or tube of metal is formed over a mandrel by one or more rollers using tremendous pressure. We form one piece component shapes which nobody else can.

Precision metal forming as the world s premier flowforming manufacturer pmf can produce component shapes beyond the means of conventional metal forming at a more economical price. Using flow punch forming technology the flowform screw causes the sheet metal to heat using a combination of axial force and relatively high screwdriver speed.
