Sheet Metal Cabinets Production Equipment

Complete Equipment Solutions for Sheet Metal Cabinet Manufacturing

Sheet metal cabinets are everywhere: server cabinets protecting IT infrastructure, storage cabinets in workshops, safety cabinets for hazardous materials, electronic cabinets housing sensitive controls, and stainless steel cabinets for food or medical environments. Producing high‑quality cabinets requires precise cutting of flat panels, accurate bending of box shapes, and clean welding of seams and mounting points.

ARCUS provides the complete equipment ecosystem to manufacture all types of sheet metal cabinets in‑house. Our fiber laser cutters, CNC press brakes, and welding systems are engineered to handle mild steel, stainless steel, aluminum, and even galvanized materials—from lightweight electronics cabinets to heavy‑duty industrial storage units. Contact us today to discuss which equipment configuration fits your cabinet production volume and material requirements.

The ARCUS Cabinet Manufacturing Process

Learn Sheet Metal Fabrication

Step 1: Laser Cutting – Panels, Doors, and Cutouts

Using an ARCUS fiber laser cutter, you cut all flat parts: front/back panels, side panels, doors, internal shelves, and mounting rails. Cutouts for ventilation, displays, locks, and cable entry are done in the same operation. Equipment: ARCUS Fiber Laser (2kW‑12kW depending on max thickness) Key capabilities: ±0.005″ hole position accuracy for mounting rails Nitrogen cutting for stainless cabinets (preserves brushed finish) Micro‑tab nesting to keep small parts (hinges, brackets) organized

Step 2: Deburring (Recommended)

Remove micro‑burrs from laser‑cut edges – especially important for stainless cabinets where sharp edges are a safety hazard and for painted cabinets where burrs affect coating adhesion. Equipment: In‑line or standalone deburring machine (we can recommend integration)

Step 3: Bending – Forming the Box

Bend the flat panels into 3D cabinet shapes: form the main body (four sides folded up), doors, and internal shelves. Complex cabinets may require multiple bend sequences. Equipment: ARCUS CNC Press Brake (100‑200 tons) Key capabilities: ±0.5° bend angle accuracy – essential for door fit Crowning table for long panels (e.g., 48″ cabinet width) – ensures straight bends without bowing Multi‑axis backgauge for sequential bends Equipment: ARCUS CNC Press Brake (100‑300 tons) Key capabilities: ±0.5° bend angle accuracy Multi‑axis backgauge for sequential bends Tooling for hems, offsets, radius bends, and acute angles

Step 4: Welding – Seam, Corner & Bracket Welding

Weld the rear corners, attach internal rack rails, add mounting brackets, and seal any seams where dust or moisture could enter. For stainless steel cabinets, TIG welding with back‑purging produces clean, sanitary seams. Equipment: ARCUS TIG or MIG Welding System Key capabilities: Low‑heat input to prevent panel warping Pulse control for spatter‑free stainless welds Programmable schedules for corner joints and rail attachments

Step 5: Finishing Preparation

While ARCUS does not perform finishing, our machines produce surfaces ready for powder coating, painting, or anodizing with minimal pre‑work. Nitrogen‑cut stainless edges have no oxide scale – they can go directly to passivation or assembly.

Step 6: Assembly

Your team installs hinges, latches, shelves, and hardware. Our machines produce parts with accurate mounting hole locations – assembly is fast and predictable.

    Frequently Asked Questions

    Q: What laser power do I need to cut 14ga (0.075″) steel cabinets?

    A: 2kW cuts 14ga at very high speed (over 300 IPM). For occasional ¼″ reinforcement plates, 3kW‑4kW is more versatile. We provide a thickness‑speed chart.

    Q: How do I ensure cabinet doors fit straight without gaps?

    A: Use a press brake with crowning table (standard on ARCUS H series). It automatically compensates for deflection, producing perfectly straight bends across long panels.

    Q: Can I cut stainless steel #4 brushed sheet without scratching the finish?

    A: Yes. ARCUS lasers include a low‑pressure follower, a pointed slat table, and specific nozzle standoff settings – all designed to protect brushed surfaces. Many medical cabinet manufacturers use this.

    Q: What welding method is best for visible corners on stainless steel cabinets?

    A: TIG welding with pulse control and back‑purging. ARCUS TIG 200P includes pre‑programmed corner joint schedules – minimal heat tint, no spatter, ready for passivation.

    Q: Can you supply a complete cabinet fabrication line (laser, press brake, welder)?

    A: Yes. We provide fully integrated lines from flat sheet to welded cabinet box. Ask about turnkey packages with material handling and software integration.

    Q: Do you offer training for my operators?

    A: Yes. Five days on‑site installation and training included. We also provide remote refresher sessions.

    Q: How do I get a free test cut of my cabinet design?

    A: Send a DXF or STEP drawing. We cut panels, perform bends, and (if requested) weld sample corners on ARCUS equipment and ship them back. No obligation.
