Beading is a process used to form either an internal or an external edge on a product. This is also a chipless metal-forming process. For example, an internal semi-circular form can be created in a cylinder for inserting a rubber O-ring. Alternatively, the edge of a product can be curled outwards so that it fits onto another component. In addition to a beading machine, MD3 also has various other edge-forming machines that can perform this processing technique quickly and highly accurately.
