Aluminum Forming Considerations
A sheet metal press tool for aluminum needs careful control of sliding contact, bend radii, and lubrication. Aluminum can pick up on an unprepared working surface, leaving scratches or unstable dimensions as material builds on the die. The Metal Press Tool should therefore separate cutting and forming loads where practical and use polished, accessible inserts in high-contact areas. A metal forming press tool may also need springback compensation, but the amount should come from the actual alloy condition and sample results rather than a general aluminum value.
Strip and Press Interface
The 220 mm maximum width and 144 mm maximum progression define important limits for a metal stamping press tool. Feed clearance, pilot access, carrier width, and scrap bridges must fit inside that envelope without weakening the strip. Although the nominated press is 400 T, nominal tonnage alone does not approve the job. Bed size, shut height, stroke, energy, speed range, feed height, and off-center load still need review. A press tool for metal parts should also provide unobstructed die clamping and safe access for setup.
During the first runs, the Metal Press Tool is checked for pitch stability, burr direction, bend angle, hole position, surface or profile, and tool marks. Any pickup on the aluminum contact areas is removed at its source rather than polished repeatedly without changing the condition that caused it. Part dropping off and scrap flow are observed at low speed, then confirmed again after the press rate increases. Metal press tooling intended for regular production should have replaceable wear items, clear lubrication points, and a practical route for cleaning chips from the lower die.
For an engineering quotation, provide the press specification first, then the 2D drawing and 3D drawing together with the die technical standards. The alloy temper, dimensional priorities, annual volume, and required inspection report should be included because they affect clearance, surface treatment, and the likely tryout effort. With those files, the tool concept can be matched to the real press and material condition instead of relying only on the available headline dimensions.
