OEM service
The mill is built from buyer CAD, a cut sample, or a brand specification that is already locked. We issue the roller flower and the general arrangement first. Steel is not cut until those drawings are signed.
Machine colour follows the RAL on the purchase order. The stainless nameplate, HMI language, manual and packing marks use the buyer brand.
Standard cabinet wiring is 380 V, 50 Hz, 3-phase. 220 V, 415 V, 440 V and 480 V at 60 Hz are wired when the order states the local grid.

What we change on the machine
Profile
Section shape, rib height, pitch and the thickness window come from the approved flower diagram.
Mill and auxiliaries
Station count, shaft diameter, decoiler tonnage, punch layout and the Cr12MoV cutoff blade are sized to the coil and the metres per minute written on the order.
Controls and identity
PLC and HMI usually ship as Yaskawa or Schneider. Siemens or Delta are fitted when the order names them. Colour, nameplate and screen language follow the same order.
Send the section drawing or a cut sample, coil grade and thickness, target line speed, and the site voltage.
We return the roller flower and general arrangement for written approval. Material stays unreleased until that sign-off.
The finished mill runs on the Wuxi floor. Buyer coil can be used for the factory test. Installation, inching and operator training happen after the line arrives.
Why the line is built in Wuxi
Rollers, shafts and frames are machined in the same 7,000 m² shop. The plant has more than 30 lathes, mills, grinders and machining centres.
Each mill is trial-formed before it leaves. Length and section are checked against the signed drawing.
