ABOUT Deep Draw Stamping
Technology: Deep Drawn Stamping is a sheet metal forming technique used to produce cans, cups, and similar shapes that have a high ratio of depth to diameter. Deep drawing employs multiple punch and die operations to achieve final forms. Deep drawn stampings are loosely defined as parts having greater depths than diameters. Deep drawing consists of four main operations, blanking, drawing, piercing, and trimming. In blanking, round discs of sheet metal are cut from coils of sheet stock. In drawing, an initial drawing operation forms the blank into a shallow cup, bringing most of the material into the die. In subsequent draws, the part is deepened and featured. Piercing punches any unwanted material out of the bottom of the draw, an unnecessary step when forming cups, etc. Trimming removes the top edges of the draw, what would have been the outer edges of the blank.
A number of operations can be accommodated in the deep drawing process to allow the formation of beads, curled edging, ribs, threads, etc.
Advantages: An alternative to screw machining for small, complex parts.
Seamless construction
Low material consumption
Popular for small parts but adept at forming large parts as well
Cost of tooling makes small jobs prohibitive but economies of scale apply
High precision
Deep Drawing Limitations
Walls can thin in unexpected areas
Sharp corners in the forming die can tear material
Wrinkling along the cup walls can occur if a blankholder is not used or its force is too low
Parts require draft angles for punch removal
Applications: Deep drawing's classic application is the manufacturer of cases for electrical relays, etc.
