Metal furniture production: shelving, cabinets, lockers.
A guide to a series business, not a one-off business. Why the bottleneck is never the cutting but the paint oven, why flat packing is decided on the first drawing and not at the packing bench, and what changes when you move from a classic press brake to a panel bender.
Of the five stations in this flow, four are covered from our catalogue: laser cutting, bending, shearing and packing of the finished product. The fifth, powder coating, is not part of the catalogue and it is, at the same time, the bottleneck of the flow. It is subcontracted at the start and brought in-house once volume justifies it. We would rather you knew that from the first paragraph.
It is a repeat business,
not a one-off business.
The same unit is produced in hundreds of pieces. The program is written once, the jig is built once, and the saving multiplies across every piece. Exactly the opposite of made-to-order metal fabrication, where every job starts from scratch.
Demand is large and continuous
Every new warehouse, every fitted-out shop and every factory needs shelving, lockers and cabinets. It is one of the steadiest demands in industry, and the product can be standardised.
The flat pack changes the logistics
The same unit takes up several times more volume assembled. A truck is paid for by volume, not by weight, so a product designed for flat packing has an entirely different delivery cost. And that is decided in the drawing.
You already have the machines, if you do fabrication
A metal fabrication workshop already has the laser and the press brake. Moving to your own product does not require a new machine, it requires your own catalogue, a correct flat pattern and a sales channel. It is the cheapest diversification available.
Painting decides the output
Real output is not what the laser cuts, it is what passes through the paint oven in a day. A faster laser does not increase your output. It is the most counter-intuitive rule in this flow and the most frequently ignored.
Five stations,
one of them is not in our catalogue.
Cutting, bending, shearing and packing are equipped from the catalogue. Powder coating is subcontracted or sourced separately, and it is the station that sets the pace of the entire workshop.
Your output
is what passes through the oven.
The laser cuts a day of production in a few hours. The paint oven has a fixed cycle you cannot shorten: preparation, application, curing. The workshop's real capacity is set by the slowest station, not the fastest.
The practical consequence for the investment: before buying a faster laser, check whether the painting can keep up with it. Otherwise you are paying for capacity that will turn into stock between stations.
Three configurations,
three batch lengths.
The difference is not product quality, it is the batch length you can produce at a profit. Each level has a zone where it is unbeatable and one where it loses money.
A metal fabrication workshop that wants its own repeat product instead of piece-by-piece subcontracting.
- Painting is fully subcontracted, so your lead time depends on someone else's schedule.
- On a classic press brake, every bend requires handling the part. On a long run, that becomes the real capacity limit.
- Without a dedicated process engineer, wrong flat patterns are discovered at assembly, after you have cut hundreds of parts.
A manufacturer delivering repeatedly to warehouses, retail and institutions, on standardised products.
- The panel bender is unbeatable on repetitive panels, but for atypical parts you still need a press brake alongside it.
- Painting remains the bottleneck. At this volume the decision to bring it in-house becomes unavoidable, with the investment that implies.
- You need a real finished-goods store: furniture, even flat-packed, takes up far more room than everyone estimates.
A manufacturer supplying retail chains and distributors, or exporting standardised metal furniture.
- A robotic cell needs long runs to justify itself. On a varied mix, a well-loaded panel bender produces more in a real working day.
- At this volume an in-house paint line becomes mandatory, and with it come environmental requirements and a considerable fixed monthly cost.
- Series production requires planning and material stock. Working capital grows faster than turnover.
What happens, precisely
from the drawing to the delivered pack.
The oven cycle is fixed: surface preparation, powder application, curing. It cannot be shortened, so the workshop's real output is what passes through the oven in a day, not what the laser cuts.
At the start it is subcontracted, and that is the right call: the line needs space, a booth, an oven, pre-treatment and significant energy consumption. The risk you take on is that the painter's lead time becomes your lead time.
Bringing it in-house makes sense once your volume fills the oven on its own. Until then, negotiate firm lead times and write them into the customer contract, do not simply hope.
The powder coating line is not part of the standard catalogue. It is sourced separately or subcontracted.
Assembled,
you are shipping truckloads of air.
The same unit takes up several times more volume assembled than flat-packed, and a truck is paid for by volume. The difference is not one of packaging, it is one of design: demountable joints, hardware and the assembly sequence are decided on the first drawing.
A product conceived as a welded assembly cannot be turned into a kit later on. That is why design is the first stage of the flow, not a formality that precedes production.
Four categories,
two of which buy in series.
Warehousing and logistics
Pallet racking and light-duty shelving, in large runs, with declared load requirements. They order repeatedly and to a plan.
Retail
Shop shelving and display furniture. Stricter aesthetic requirements and campaigns with fixed deadlines.
Institutions and factories
Lockers, cabinets, workshop furniture. Purchased through tender procedures, with detailed specifications.
Offices and archives
Archive cabinets, metal office furniture. Medium volumes, requirements for a good finish.
Ten mistakes,
two of design and eight of calculation.
The first two happen at the drawing stage and can never be corrected. The rest can be corrected, but each one costs a whole batch before you notice it.
You design the product welded, then try to turn it into a flat pack. It cannot be done: the decision is on the first drawing.
You buy a faster laser to raise output, but the bottleneck is the paint oven, not the cutting.
You subcontract the painting without firm lead times in the contract, then pay penalties for someone else's delay.
You weld continuously on thin sheet, distort it, then spend more time grinding than assembling.
You have no process engineer, and wrong flat patterns are discovered after you have cut and bent hundreds of identical parts.
You buy a panel bender for a highly varied mix, where a well-loaded press brake would have produced more.
You do not plan for the finished-goods store, and the packs block the working area.
You ship without the numbered hardware bag and without instructions, and the kit comes back.
You ship assembled product, meaning you pay for truckloads of air, on a product that could have shipped flat.
You accept well-paid one-off orders and fill your series machines with work that does not pay for them.
From the decision to the first catalogue product,
in 100 days.
Choosing your own catalogue
- You settle on two or three products you will repeat: warehouse shelving, locker, cabinet.
- You check who buys in your area and to what specifications: declared load, dimensions, finish.
- You design the products for flat packing from the outset, not as a later adaptation.
Configuring the four stations
- You receive the laser, bending and shearing configuration for your thicknesses and formats.
- You decide press brake, panel bender or both, depending on your series-to-variety ratio.
- You settle the packing solution for the flat pack: erector, sealing, strapping.
Solving the painting
- You identify two painters and negotiate firm lead times, with penalties on both sides.
- You work out at what volume bringing the paint line in-house becomes justified.
- You submit the leasing file for the four stations we equip now.
Preparing the building
- Power connection, dry compressed air, extraction at the cutting station, a separate packing area.
- The finished-goods store, sized for packs stacked vertically.
- Recruiting the process engineer and the operators, plus the first assembly jigs.
The first catalogue product
- Commissioning, training, a complete program on a real product.
- A trial run of ten pieces, with times measured at every station.
- The first flat-pack delivery, with instructions and hardware, to a real customer.
You can finance in two steps:
production now, painting at volume.
The four stations we equip can be financed through leasing, with a down payment from 0% and the first instalment after delivery. The paint line remains a separate decision, taken once your volume fills the oven on its own, and at that point the grant route is worth checking too.
About the production
of metal furniture.
You get the machine configuration for the four stations we cover from the catalogue: laser cutting, bending, shearing and packing of the finished product. The fifth station, powder coating, is not in our catalogue and is, at the same time, the bottleneck of the flow. We say so in the first paragraph, so you know what comes from us and what has to be bought elsewhere or subcontracted.
Tell us what products you want
to repeat in series.
The products in your catalogue, the sheet thicknesses and the estimated batch sizes. You get the cutting and bending configuration, the press brake versus panel bender decision argued on your own series-to-variety ratio, the packing solution for flat packs, and the volume threshold at which bringing painting in-house becomes worthwhile.
