Metal Stamping Machines: The Press Line as One System

Press, feeding line and control documented as one system: coil from 70 to 1,000 mm wide and 0.3 to 4.5 mm thick, fed to ±0.15 mm (the 3-in-1 figure, under a 500 mm feeding length), into presses from 15 to 2,000 tons.

Metal Stamping Machines as Production Equipment

A metal stamping machine is bought as equipment, not as a catalogue item: the press, the coil feeding line in front of it, the die inside it and the control system tying them together. This page covers the equipment side of that purchase — what the manufacturer documents as a system — while the stamping press page covers model selection and the mechanical press page covers the drive families.

The Line: Press + Feeding + Control

The manufacturer's feeding catalogue is built around the press line. Its 3-in-1 decoiler-straightener-feeder combines the three functions in one unit under a single touch screen, with a self-diagnosis system; the published material window is 0.3 to 4.5 mm thickness, 70 to 1,000 mm coil width and coils up to 7 tons, with feeding accuracy held to ±0.15 mm under a 500 mm feeding length. The NLF2 servo uncoiler-straightener-feeder covers 0.3 to 3.2 mm with 11 levelling rollers. On the press side, the electric control system is documented as designed for automation compatibility, and the C1N page documents connection with single presses, progressive dies, mechanical arms and transfer systems.

Materials and Parts the Equipment Is Documented For

The official product descriptions start from thin steel plate work — blanking, punching, bending and forming of small parts from blanks or coil stock (C1N, A1) — and the range extends from there: deep throat presses for wide and perforated sheet, servo presses documented for high-tensile strength steel automotive parts, high-speed presses for motor laminations and electronic parts, and the S2N/T2N straight side presses for large, deep-formed and odd-shaped parts on transfer systems. Application fields are collected on the applications page.

Equipment Checks Before You Commit

  • Power supply: main motors run from 2.2 kW (C1N-15) to 160 kW (S2N-1600) in the published tables; confirm your plant supply against the quoted model.
  • Air supply: the crank tables specify 6 kg/cm² working air pressure across the C1N, A1, C2N, D1N, D2N and M1N series; die cushions and clutches budget from the same supply.
  • Weight and foundation: the A1 table publishes total weights of 1.9 to 30 tons across its nine models; two-point and eccentric presses are heavier — the foundation drawing comes with the quoted model.
  • Safety equipment: light curtains and safety devices appear as standard or optional equipment on the hydraulic range; state your market's safety requirements in the enquiry so they are configured at the factory.
  • Spares and service: the manufacturer sells and services its presses (its registered business scope) and documents a service network inside China; export service arrangements are confirmed per order in the quotation.

Frequently Asked Questions

Can I buy a complete stamping line from one supplier here?

The documented components — press, decoiler, straightener, feeder, and transfer or mechanical-arm connection — are all in this manufacturer's catalogue, and the press control system is designed for automation compatibility. How the components are combined into a single quotation, and how the interfaces between them are divided, is confirmed for your line in the enquiry.

What coil can the feeding equipment handle?

The published 3-in-1 window is 0.3-4.5 mm thick, 70-1,000 mm wide, up to 7-ton coils, with ±0.15 mm feeding accuracy under a 500 mm feeding length. Wider or heavier coil is a customization question for the quotation.

Does the equipment stamp stainless and high-tensile steel?

High-tensile strength steel is documented on the servo press pages (EC1, EM2). For crank presses, give the material grade and thickness in the enquiry — suitability for a given grade and thickness is confirmed in the quotation.

What does the quotation include?

The configured machine, documented options, packing and delivery terms to your port. Installation support and service terms for export orders are stated in the quotation itself.
