Written from the investor's perspective: what to buy, what it really costs and which formalities await. Numbers, not fluff.

• How an anodising line works: the full anatomy, from tank sequence to wastewater station

  An anodising line is a small chemical plant sold as a machine. We take it apart component by component: what the rectifier and the chiller really decide, why ventilation and wastewater neutralisation belong in the first budget rather than the last, and how the three automation levels change crew, capacity and colour repeatability.

• Factory acceptance test (FAT) on Chinese machinery — how to pay for evidence, not promises

  The factory acceptance test is the single strongest lever a machinery buyer has over a factory 9,000 km away — and most buyers throw it away by signing a contract that never defines it. Here is what a proper FAT protocol contains, when witnessing in person beats live video, how to structure payments around FAT acceptance, and what to do when the test finds problems. It will.

• New Chinese extrusion press or used European? An honest TCO comparison

  A second-hand extrusion press from Europe looks half the price of a new Chinese one — until you add dismantling, overhaul, obsolete spares and forty-year-old energy consumption. We run the 10-year numbers on both options, and finish with an honest list of cases where the used machine really is the better buy.

• How much does an aluminium extrusion line cost? A full price breakdown

  Real numbers instead of "price on request": extrusion press prices by tonnage, what the furnaces and handling equipment add, complete-line scenarios from China, and what EU or Gulf buyers pay on top in freight, duty and VAT.

• CE marking on Chinese machinery — what EU buyers must actually check

  Most "CE certificates" attached to Chinese machinery quotes are commercial paper, not proof of conformity. Here is how to tell the difference, what the Machinery Regulation (EU) 2023/1230 changes from January 2027, and who really carries the responsibility in each purchase setup.

• How to start an aluminium extrusion plant: building, machines, budget, timeline

  What it actually takes to go from an empty hall to saleable profiles: choosing press tonnage, the building and utilities an extrusion line needs, a realistic setup budget, the staffing nobody warns you about, and the five mistakes that cost first-time extruders the most.

• Vertical vs horizontal powder coating line for aluminium profiles: which one should you buy?

  A vertical powder coating line does 800–1200 t/month with 2–3 operators on half the floor space — but costs 3–4 times more and needs a 9-metre building. A data-driven comparison with published price ranges and a decision matrix, written from the investor's side of the table.
