Les six postes, et ceux que vous pouvez ignorer<\/h2>\n

La plupart des usines d'armoires n'ont pas besoin des six. L'ordre compte plus que le nombre.
\nD\u00e9roulage.<\/strong> Le d\u00e9rouleur d\u00e9roule la bobine de bande et \u00e9tablit un \u00e9quilibre de mati\u00e8re synchrone avec la planeuse. STON\u2019<\/a>Le corps et la base du d\u00e9rouleur de STON sont des structures soud\u00e9es ayant subi un traitement de vieillissement thermique. La capacit\u00e9 de la bobine est \u226410 T.
\nPlanage.<\/strong> Rouleaux de planage en 40Cr, avec des roulements auto-aligneurs ou \u00e0 aiguilles sur les rouleaux de travail. La pr\u00e9cision de planage annonc\u00e9e est de \u00b11 mm\/m\u00b2, avec une pr\u00e9cision diagonale \u22641 mm\/2000 mm. Ce poste est ce qui rend l\u2019alimentation en bobine viable \u2014 une \u00e9bauche non plan\u00e9e ne conservera pas l\u2019angle de pliage sur une plieuse de panneaux.
\nD\u00e9coupe laser.<\/strong> Fibre laser, 1 kW to 6 kW, with a cutting-parameter database and real-time parameter adjustment during the cut. This is your blanking station for cabinet doors, side panels and back panels with cutouts.<\/p>\n

Turret punching.<\/strong> The station that earns its place when your parts carry louvers, ribs, embossing or high hole counts. Punching, trimming, forming, louvering and rib pressing on one turret.
\nBending.<\/strong> A CNC panel bender completes multi-angle bends on a panel in one clamping, with angle compensation and program switching between products.
\nStacking, and optionally welding.<\/strong> A robot welding cell with positioner, fixtures and seam tracking can be attached for butt, fillet and spot welding of the cabinet body.
\nFor a cabinet plant running one dominant SKU family, stations 1, 2, 3 and 5 form the minimum viable line. Skip the turret and you lose louvers. Skip the leveler and you lose bend consistency, which is not a trade you can recover downstream.<\/p>\n

\"STON<\/p>\n

A worked layout: 1,800 \u00d7 800 \u00d7 600 mm distribution cabinet, 1.5 mm CRS<\/h2>\n

Take a standard low-voltage distribution enclosure. Eight sheet parts per body: two side panels (1,800 \u00d7 600), back panel (1,800 \u00d7 800), door (1,800 \u00d7 800), top and bottom (800 \u00d7 600 each), and a mounting plate (1,600 \u00d7 700).
\nNet blank area comes to about 7.12 m\u00b2 per cabinet. At 11.775 kg\/m\u00b2 for 1.5 mm steel, that is 84 kg of finished material per body.
\nCoil-fed nesting on a 1,500 mm strip lets you run the two 600 mm side panels two-up and the 800 mm panels one-up with the balance recovered by small parts. Working at 88% utilisation, gross consumption is 8.09 m\u00b2, or 95 kg per cabinet. One 10 T coil therefore yields approximately 105 cabinet bodies.
\nCompare that against sheet-fed blanking from 1,250 \u00d7 2,500 sheets, where a mixed cabinet nest realistically lands near 78% utilisation. Gross consumption rises to 9.13 m\u00b2 and 107.5 kg. The difference is 12.2 kg per cabinet, about 11%. At 25,000 cabinets a year, that is 305 tonnes of steel. Nobody in the SERP publishes this number, and it is frequently larger than the labour saving.<\/p>\n

Uncoiler, leveler and stacker lengths are set by coil weight, leveling accuracy target and buffer sizing, and are issued on the project layout drawing rather than in the standard product tables. The three published machine footprints alone total roughly 15 m of length. Adding coil handling, leveling, inter-station buffers and stacking, 35 to 45 m of total line length is the planning figure to reserve. Confirm against the layout drawing before pouring foundations.
\nWorking height across the coil section is +800 mm, which sets your operator platform and buffer table heights.
\nOne layout decision that gets made too late: whether the laser and the turret sit in series on one flow, or in parallel branches fed from a common buffer. Series is simpler to control and cheaper. Parallel is what you want if your part mix splits into “high hole count, simple outline” and “complex outline, few holes” \u2014 a split that describes most cabinet plants running both bodies and vented doors.<\/p>\n

Model designations appear as A \/ A+ \/ B \/ B+ \/ C \/ D \/ D+ in the product tables and as A2 \/ B2 \/ C2 \/ D2 \/ F2 on the official product page. A maximum bending length of 4,100 mm also appears in company overview material against 2,800 mm in the model table, and a \u00b10.01 mm accuracy claim appears against the \u00b10.1 mm\/m dimensional accuracy in the same table. Treat the model table as governing and request written confirmation of series naming, maximum length and accuracy basis on your quotation.<\/p>\n

For the 1,800 \u00d7 600 side panel in this example, C (2000) covers the envelope. The welded frame is rated CR 1.5 mm at full bend, which puts a 1.5 mm cabinet panel exactly at the ceiling. Specify the cast frame instead. The margin costs money on the quotation and saves it over five years of tool and angle stability.<\/p>\n

Turret punch press, SF Series servo<\/strong><\/p>\n

Maximum turret speed 40 rpm; machining accuracy \u00b10.1 mm; maximum load 150 kg; combined power consumption approximately 3\u20135 kW; air 0.55 MPa; 380 V \u00b15%; external dimensions 5,200 \u00d7 5,000\/5,500\/6,500 \u00d7 2,230 mm. Table structure is a brush and omnidirectional steel ball composite, which is the detail that governs scratch rate on pre-painted or brushed stainless cabinet faces.
\nThe mechanical JT Series runs 30 rpm turret speed at \u22642 kW combined consumption. Lower energy, lower flexibility.
\nIf your part mix genuinely needs both punching and contour cutting on the same part in one clamping, the SFL punch-laser combined machine handles it: 300\/400 kN (30\/40 T) punching force, “O” type closed frame, X-axis 2,500 mm in one position and up to 5,000 mm with secondary positioning, Y-axis 1,250\/1,500 mm, step pitch 405 times\/minute at 5 mm, and a die layout of 16A, 11B, 3C, 2D including 1B and 1C rotary stations. STON states it occupies approximately 40% less space than a separate punch press plus laser cutter, and removes the handling, re-clamping and re-alignment time between them.<\/p>\n

\"Turret<\/p>\n

Cycle time: the bottleneck is not where buyers expect<\/strong><\/h2>\n

The station that limits a cabinet line is almost never the punch press. It is either the laser or the bender, and which one depends on hole count versus bend count in your specific part family.
\nHere is the model for the eight-part cabinet body above. Every assumption is marked.
\nLaser station. Cut path per cabinet set: blank perimeters total approximately 30.2 m; internal features (DIN rail cutouts, fixing holes, cable entries, ventilation) add roughly 12 m; shared edges in coil nesting recover about 4 m. Net \u2248 38 m.<\/p>\n

Assumption: effective cutting speed for 1.5 mm cold-rolled steel at 3 kW falls in the 12\u201320 m\/min band under normal parameters. Using 15 m\/min for planning: 2.53 min of cutting. Add 25% for piercing, rapid traverse and indexing: \u2248 3.2 min per cabinet set. Verify against the cutting-parameter database supplied with the machine, not against this article.<\/p>\n

Turret station. Approximately 180 hits per cabinet set for fixing holes, louvers and cutouts.
\nAssumption: 200\u2013300 effective hits\/min including axis moves. That gives 36\u201354 s of punching, plus sheet handling. \u2248 1.2 min per cabinet set. This station has spare capacity in this example. It becomes the bottleneck the moment you add a louvered ventilation door: 800 louvers pushes the same station past 4 minutes.
\nBending station. Approximately 36 bend cycles per cabinet set (four edges with return flanges on the two sides, back and door; single flanges on top, bottom and mounting plate).<\/p>\n

Assumption: 2.5\u20133.5 s per bend cycle including axis repositioning, and 8\u201312 s per part for load and unload with truss or robot handling. That gives 90\u2013126 s of bending plus 64\u201396 s of handling. \u2248 2.6\u20133.7 min per cabinet set. STON’s tables publish 15 servo axes and the 0\u2013180\u00b0 range but not a per-bend cycle figure; request a simulated cycle time against your own DXF files before committing to a throughput number.<\/p>\n\n\n\n\n\n\n\n\n\n

Line output<\/strong>. Bottleneck 3.2\u20133.5 min gives 17\u201318 cabinet sets per hour theoretical. At 85% availability, which is the realistic planning figure once you account for coil changes, program changes, nozzle and lens maintenance and tool changes, output is 14\u201315 sets per hour, or 115\u2013120 cabinet bodies per 8-hour shift.
\nSingle shift, 250 working days: approximately 28,750 bodies a year. Two shifts: 57,500.
\nA note on how this differs from what the market publishes. Compared with the European line-builder category, which typically advertises a single headline figure such as seconds per part or products per minute, the number above is deliberately built from station cycles multiplied by an availability factor. A six-second headline figure describes one station running one part under ideal conditions. It is not a line rate, and quoting it back to your board as a capacity plan will cost you credibility when the line commissions.<\/p>\n

\"STON<\/p>\n

An eight-step evaluation sequence<\/h2>\n
    \n
  1. Freeze the part family. Pick the three cabinet SKUs that represent 60%+ of volume. Export DXF files. Everything downstream is calculated from these, not from a category description.<\/li>\n
  2. Count bends and hits per part. Not per cabinet. Per part, because that is how station balance is calculated.<\/li>\n
  3. Nest against your actual coil widths. Ask the supplier for a nesting output at your widths and get the utilisation percentage in writing.<\/li>\n
  4. Request a simulated cycle time per station against your DXF files, with the availability factor stated separately from the theoretical cycle.<\/li>\n
  5. Resolve the specification conflicts before the contract. Coil width range, coil inner diameter, panel bender series naming, maximum bending length and the accuracy basis. Get one number per parameter, signed.<\/li>\n
  6. Verify the utility gap. Installed kVA, air flow at pressure, crane hook height, floor loading, drainage for the chiller.<\/li>\n
  7. Audit the manufacturing basis of the quotation. Ask which components are made in-house and which are bought in. STON keeps casting, heat treatment, machining, welding, assembly and inspection inside a 20,000 \u33a1 factory with a published \u00b10.05 mm assembly accuracy, and holds ISO 9001 certification along with Shandong “Gazelle Enterprise” and “Specialized and Innovative Enterprise” recognition. A trading company cannot answer this question, which makes it a useful filter.<\/li>\n
  8. Fix the training and spares terms. Named trainees, hours, location, spare parts list with lead times, remote support scope.<\/li>\n<\/ol>\n

    Safety and CE documentation for a linked line<\/h2>\n

    A production line is not a machine. Under Machinery Directive 2006\/42\/EC, linked machinery placed on the EU market as a functional unit is treated as an assembly of machinery, which means the line as installed requires its own risk assessment, technical file and Declaration of Conformity \u2014 not simply a folder of CE certificates for individual stations. Regulation (EU) 2023\/1230 now governs new placements.
    \nAsk specifically for:<\/p>\n

      \n
    1. Risk assessment for the assembly, conducted to EN ISO 12100, covering the interfaces between stations rather than each station in isolation<\/li>\n
    2. Safety-related control system performance level to EN ISO 13849-1, with the PL and category stated for each safety function, including line stop propagation across stations<\/li>\n
    3. Where a press brake sits in or adjacent to the line, conformity to EN 12622 and EN ISO 16092<\/li>\n
    4. Guarding and interlock drawings for the coil section, where the highest-energy hazards sit<\/li>\n
    5. Documentation language matched to your operators’ working language, which the Directive requires and which is skipped more often than any other item.<\/li>\n<\/ol>\n

      STON<\/a>‘s machines carry ISO and CE certification, and safety hardware including laser protection devices with real-time area monitoring and immediate stop, over-tonnage protection on the mechanical turret, and fully enclosed rear guarding on the flexible edge bending machines. Certification of the individual machine is the starting point. The assembly file is what your factory inspector will ask for.<\/p>\n

      FAQ<\/h2>\n

      Q: What throughput should I actually promise my customers after installing a cabinet line? <\/strong><\/p>\n

      A: Use the bottleneck station cycle multiplied by 0.85 availability, then apply a further 0.9 factor for the first six months while your programmers build the parameter library. For the 1.5 mm distribution cabinet example, that means promising 100\u2013105 bodies per shift in year one against a theoretical 17\u201318 per hour.<\/p>\n

      Q: Can one line handle both 0.8 mm galvanised and 2.0 mm cold-rolled steel? <\/strong><\/p>\n

      A: Within the published 0.5\u20132.0 mm envelope, yes, but not without consequence. Leveling roller settings, cutting parameters and bend compensation all change, so treat each thickness as a separate setup with its own changeover time. At 2.0 mm cold-rolled on the panel bender, you need the cast frame; the welded frame is rated CR 1.5 mm at full bend. Stainless is capped at 1.5 mm on the coil line and SS 1.2 mm at full bend on the cast panel bender.<\/p>\n

      Q: How much floor space do I need to reserve? <\/strong><\/p>\n

      A: The three published machine footprints in a typical cabinet configuration total roughly 15 m of length. Reserve 35\u201345 m of line length and 6\u20138 m of width to accommodate coil handling, leveling, inter-station buffers, stacking and maintenance access. The layout drawing governs; treat this as the space you ask your landlord for, not the space you build to.<\/p>\n

      Q: What does a cabinet production line cost?<\/strong><\/p>\n

      A: It is quotation-based. Installed cost varies with laser power (1\u20136 kW), coil width, panel bender model and frame type, turret series, and how much of the loading and unloading is automated. Rather than accept a range from any website, use the capex recovery arithmetic in this article: each US$100,000 of installed cost adds about US$0.57 per cabinet at 25,000 bodies a year over seven years. That converts a quotation into a per-part number you can defend.<\/p>\n

      Q: Is a punch-laser combined machine a substitute for separate stations? <\/strong><\/p>\n

      A: It is a substitute when your parts need both punching and contour cutting in one clamping and your volume does not justify two machines. STON’s SFL states approximately 40% less floor space than a separate punch press plus laser cutter, with the handling and re-alignment time between them removed. It is not a substitute at high volume on either operation individually, because both functions share one gantry and one clamping cycle.<\/p>\n

      Q: How long from contract to production? <\/strong><\/p>\n

      A: Ask for it in four separate numbers rather than one: manufacturing, shipping, installation and commissioning, and ramp to rated output. The fourth number is the one that gets omitted and the one that determines when you can accept orders against the new capacity.<\/p>\n

      Q: What happens to my existing press brakes? <\/strong><\/p>\n

      A: Keep at least one. Frames, base channels, heavy brackets and anything outside the 2.0 mm coil envelope still belong on a press brake, and a machine in the 100 T\/3200 mm to 320 T\/4100 mm range covers the residue. Factories that sell off all their brakes on day one tend to buy one back within eighteen months.<\/p>","protected":false},"excerpt":{"rendered":"
