Flow Forming Sheet Metal

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.

Flow forming sheet metal.

About 90 percent of spun parts can be formed by starting with a blank disk trimmed from standard commercial sheet metal. For a full selection of special types of steel please visit our materials page. 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. Better yet with our extensive range of processes we can make more than just traditional cones and cylinders.

As mentioned the punch and die setup is somewhat similar to a sheet metal cutting operation such as punching or blanking. 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. We form one piece component shapes which nobody else can. 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.

When you combine the flowforming process with pmf s other strategic in house forming fabricating and assembly processes you take flow forming to the next level. Deep drawing practice. Once the material has been penetrated the polygonal shape of the screw forms a metric female thread. We call it flowformingplus a powerful assortment of custom flowforming metal working solutions from concept to final product that have very tangible benefits for our.

Deep drawing is a sheet metal forming process that involves complex material flow and force distributions.
