Metal forming press

Application review for a metal forming press used on sheet blanks that must form or deep-draw to a named depth. Operating duty decides blank handling, stroke control and how first-good parts are counted. Upstream coil feeding or downstream trimming is not implied. Who owns die settings and recipe records should be named before you compare island prices.

Operating duty

Operating context
A metal forming press in this scope sits in a sheet-forming cell with three-phase supply, a defined forming area and a path for blanks and formed parts. Deep-drawing duty needs a stated draw depth, blank-holder force and a trial blank of the production alloy. Shallow forming of panels is a different duty even when the steel grade matches. Representative production samples of blanks, lubricant practice and the actual finished drawing should travel with the RFQ so force and speed proposals match the thickness you will run, not a brochure average. Stamping progressive dies and press-brake bending remain separate equipment families.

Operating duty: Design input

Describe how blanks arrive and how formed parts leave. Record alloy, temper, thickness, largest blank, and the draw depth that must be achieved. State whether force is expected from a punch through the stroke or from a fluid-cell chamber, and name the forming-area millimetres the die must occupy. Ceiling height, pit limits and whether a destacker or robot must sit outside the machine footprint belong here. Name the US plant destination so crate and voltage assumptions are not left implicit.

Supplier answer

Ask for a force-versus-stroke statement tied to that draw depth, including whether a blank holder or cushion is active. Request who writes the first recipe and what editing access the buyer receives after handover. Confirm connected kW, supply frequency and whether cooling water is required. If a second family uses a different die set, it must be priced as a second configuration, not as a free conversion of the first punch. Upstream coil lines and downstream lasers stay out of the answer unless the RFQ added them.

Open deviation

Do not copy a chamber-pressure maximum onto a punch-force brief. Do not use a no-load ram rating as plant output when blank holding remains manual. If welding or stamping appears in a brochure, treat those as different projects. If a vendor quotes only the press while you need the die, blank holder and destacker in the same cell, the application is not yet specified.

Interfaces that must be confirmed include electrical supply, utilities and any PLC handshake with adjacent equipment. Throughput should be described as acceptable formed parts per shift under named blank conditions. Cycle time on an empty ram does not establish that output. FAT and SAT should use the same production-intent blanks. If the cell later adds a press brake, that is a second RFQ. We can circulate a comparison of duty statements; we cannot certify the forming process or promise a percent cost reduction.
