What is Metal stamping as it is related to MGC`s business?
Simply put metal stamping is the process of using a tool - the "Die" mounted in a press to form and cut a part into a desired shape by utilizing the vertical press motion (stroke). When in production, the raw material which is fed into the die is mostly flat metal strips or coils of flat material. It is available in various widths, thicknesses and materials into a multitude of shapes, such as the thousands of metal parts in every car. The various stamping processes produce generally one or two repeatable parts per press stroke.
Parts are then monitored within manufacturing tolerances to assure fit and function. Some dies produce left and right hand parts from within the same die at the same time. For conventianal stamping dies are mostly are of three types, the single transfer station, blanking or progressive types. Automotive dies of medium size components often run at speeds of 10 - 300 SPM (strokes per minute). When the press is in motion it will "stroke" up and down with a preset distance. The two die halves, upper and lower are aligned with a pin type of guide system and open and close using the applied press force, to form or pierce and cut the raw material. Thus allowing precision repeatability of each press stroke and part produced. Part accuracies and repeatability is usually measured in much smaller increments than a millimeter, often tolerances for hole locations are +- .002" for location and +- .010" for trim lines or outer part edges. Tolerances can vary and should be designed to suit the anticipate stamping die cost which is driven by the final part drawing.
We are able to assist you with your in house stamping process. We have the majority of experience within the 100 - 5000 Ton range, primarily, but not limited to automotive stamping part and assembly applications. We primarily get involved with trouble-shooting, quality improvements or material savings, die stamping facility re-locations or PPAP assistance, we are hands on and don`t stop by simply consulting, we achieve our goals.
