(Click Image to Enlarge)Stamping of a Stainless Steel Electrode

At G&M Manufacturing, we are a recognized leader in the stamping industry, servicing a variety of customers, including insert molders supplying the exercise equipment industry. This project included G&M designing a process to stamp a stainless steel electrode and terminal in one step thus eliminating a manufacturing process adding a cost savings which was passed onto the customer. The part measured 4″ long, .9″ wide, and .7″ high. We utilized our 60 ton capacity Minster straight side press and over formed the terminal tab in the progressive die. The customer supplied drawings called out the use of .02″ thick, 304 stainless steel. We manufacture 15,000 electrodes annually for this Midwest customer and utilize OGP vision system and pin gage testing to verify dimensional accuracy, and the required tolerance of ±.002″. This project highlights our ability to accomplish the geometrically challenging parts and minimize cost to our customers.
