FACTORY · SHIJIAZHUANG, HEBEI

One workshop, from coil steel to a coated cabinet.

Cutting, forming, welding and a 7-stage coating line under one roof — 8,000 m² total facility (6,000 m² production workshop).

The machine row in the production workshop: the nearest CNC press brake with a formed panel on its bed, further machines receding toward the roof structure
Production workshop — CNC press brake forming cabinet panels.

Seven steps, in order

  1. 01

    Blank

    Coil and sheet steel cut to size.

    Guillotine shear

  2. 02

    Punch

    CNC turret punch.

    100% incoming steel inspection (Baosteel / Ansteel SPCC)

  3. 03

    Form

    CNC press brake.

    ±0.5 mm dimensional accuracy on formed parts

  4. 04

    Weld

    Robotic welding with manual touch-up.

    No missed or porous welds

  5. 05

    Pre-treat

    Degreasing, rinse, phosphating, rinse, drying.

    Phosphate layer before powder

  6. 06

    Coat

    Electrostatic powder coating.

    Dry film 80–120 μm

  7. 07

    Cure

    Oven curing.

    Adhesion class 1 (GB/T 9286—2021)

Uprights 2.0 mm · doors 1.2 mm · front mesh ≥75% · rear mesh ≥60%

Three stages, in detail

  • Bending die at the moment of the stroke: the punch descending into the die with a cold-rolled steel sheet bending up from both sides of the tooling

    Forming

    CNC press brake. ±0.5 mm on formed parts.

    Uprights 2.0 mm, doors 1.2 mm, SPCC cold-rolled steel.

  • A cabinet base frame clamped square on a steel jig with one continuous weld bead running along the corner joint

    Welding

    Robotic welding with manual touch-up.

    Welds are inspected for missed and porous joints before coating.

  • The coating area: a powder spray booth with a suspended conveyor rail carrying freshly coated panels on hooks, an oven mouth behind

    Coating

    Seven-stage line: degreasing, rinse, phosphating, rinse, drying, electrostatic powder coating, curing.

    Dry film 80–120 μm; adhesion class 1.

Steel arrives inspected, not assumed.

Cold-rolled SPCC steel from Baosteel and Ansteel is checked on arrival before it enters the line.

Uprights are 2.0 mm, doors and side panels 1.2 mm.

Incoming steel · 100% inspection, certificate retained per batch

Incoming steel and formed parts staged beside the press brake.

Every cabinet leaves with a test record.

What comes off this line gets tested

  • Cover page of the CAICT seismic test report for the cabinet

    18 pages · reproduced page by page on the quality page.

  • Cover of the third-party load test report

    Load test report

    3 pages — the document behind the 1,500 kg figure on reinforced-frame models.

  • Cover of the cold aisle containment test report

    Cold aisle containment test report

    4 pages · test data on the enclosed aisle.
