Although shear forming is similar to metal spinning, it differs by maintaining a constant diameter of the blank. This tactic can achieve reductions in wall thickness down the part. Generally this spinning technique can offer material enhancements in elongation and tensile strength via the coldworking of the input blank.
This Spincraft capability allows the unique ability to utilize maximum forming force to save on raw material costs. Likewise, this will optimize the fly-to-buy ratio of the delivered product. Through detailed engineering design and analysis, we can accomplish providing accurate, repeatable solutions to customer design challenges. When customer designs exceed the limit of raw material suppliers, our shear forming ability can provide a path from concept to product realization.
Check out this video to gain an understanding of the shear spinning process. In the example seen below, we start with a flat piece of aluminum. This flat sheet blank undergoes this metal forming process in real time. You can see that the area of the final product is almost equal to the blank. As a result, by controlling the gap between the roller and the mandrel, we can maintain wall thickness.
In light of using this forming technology, you can achieve the following benefits:
