How Full Aluminum Furniture Is Made: From Profile Extrusion to Pre-Assembly

Buyers often ask what actually happens between «aluminum profile» and «finished cabinet» inside a factory. Since 2014 we have run this process every day at our 9,000㎡ plant in Dali, Foshan, producing around 100,000 panels per month. Here is a walkthrough of how full aluminum furniture is made, step by step, including the QC tests we run along the way.

Step 1: Profile Extrusion

Full aluminum furniture starts with aluminum profiles — not boards. Billets of aluminum alloy are heated and pushed through steel dies to form the cross-sections that make up cabinet frames, door frames and structural columns: U-shapes, C-channels, T-sections and multi-cavity profiles designed to carry hardware screws and hidden connectors.

Profile quality decides everything downstream. Wall thickness, straightness and the position of screw channels must stay within tolerance, or assembly on your customer’s site will never fit. Profiles can also be finished in different colors — beige, grey, bronze, wood grain — at this stage.

Step 2: Precision Cutting and Machining

Extruded profiles and aluminum panels are cut to size on CNC machines. Every drilling position, hinge pocket and connector hole is machined at this stage, guided by the confirmed shop drawings. CNC sizing is what makes flat-pack aluminum furniture repeatable: part number one in a batch must be identical to part number five hundred.

Step 3: Edge Treatment — PUR Banding or Welding

Panel edges are sealed in one of two ways. For laminated aluminum boards we use PUR edge banding: a moisture-curing adhesive that bonds the edge strip permanently and resists water and heat far better than conventional hot-melt glue. For welded aluminum panels, edges and joints are laser-welded into a single piece, then ground and polished smooth — no visible seam, no glue line at all.

Step 4: Surface Finishing

Depending on the design, surfaces receive wood grain transfer, PET or PVC film lamination, or powder coating. This is where aluminum furniture stops looking industrial: modern transfer films reproduce oak, walnut and teak convincingly, while solid-color films cover the matte palette most contemporary kitchens use. Because finishes are applied in controlled factory conditions, color stays consistent from batch to batch — important when a project is delivered in phases.

Step 5: Hardware and Assembly

Hinges, drawer slides, handles and dampers are installed against the machined positions from Step 2. Hardware is the moving part of any cabinet, so we specify it deliberately and test it: our hardware life test cycles hinges and slides to confirm they survive years of daily use before a design is approved for production.

Step 6: QC Testing and Pre-Assembly Inspection

Four standard tests run through our production:

• Load-bearing test — shelves and cabinets loaded to verify they hold real-world weight without deflection.
• Water immersion test — panels and edges submerged to confirm waterproof performance.
• Formaldehyde test — verifying the zero-formaldehyde claim with measurements, not words.
• Hardware life test — repeated open-close cycling of doors and drawers.

Then comes the step most overseas buyers tell us matters most: before packing, we pre-assemble complete units in our factory and check fit, alignment, door gaps and function. If a cabinet would not fit together in Foshan, it will not fit on your customer’s wall. Any quality problem found at this stage is resolved within 7 days.

Step 7: Packing and Shipping

Approved units are disassembled into flat packs, protected with foam and corner guards, and packed in export cartons or wooden crates depending on the product and transport mode. Because every unit was pre-assembled and checked first, packs can be grouped unit by unit so a whole-house order arrives ready for staging. We ship EXW, FOB or CIF, and we consolidate orders — furniture and panels can share one container to cut your freight cost per unit.

Standard panels leave our factory within 7 days, custom panels within 15 days, and whole-house furniture orders about 30 days after drawings are confirmed. Send us your drawings and we will respond within 24 hours with a production plan.
