Turn the edge of the hole in the sheet or workpiece into an upright edge. Our capabilities include the production of progressive dies, transfer dies, single roller coating aluminium sheet stage dies, multi-stage dies and more.Stamping DiePosted by kinglanmachine on October 30th, 2018As an inseparable part of metal stamping line,stamping dieand tooling systemismuch important in its service life and precision as it directly works on stamping parts and effects parts’ forming quality.9.Cutting: The sheet is cut by a mold and the front line is not closed.Forward extrusion: The metal blank in the cavity is in a plastically deformed state under the action of the punch pressure, so that it is extruded from the die hole, and the metal flows in the same direction as the punch.10.17.4.Bulging: a part of the hollow member (or pipe) is radically expanded to be convex.16.12.ccExport office:Room 1309, No.24.Shrinking: shrink the mouth of the hollow piece.Below is the introduction of the basic process of stamping:1.Punching1)Blanking: The die cuts the sheet along the closed line, the part that is washed down is the workpiece, and the rest is waste.Deep drawing: the sheet material is pressed into a hollow workpiece, and the wall thickness is basically unchanged.Undulations: the ribs, patterns or text are pressed out on the sheet or workpiece and all undulations are thinned.Imprinting: change the thickness of the workpiece and press the text or pattern on the surface.These punchpress dies can be created for various applications in industries such as automotive, home appliances, stationery, hand tool, hardware, computer, electronics etc.3.
