Factory Audit Checklist for Sliding Wardrobe Door Frames

A reliable factory audit for sliding wardrobe door frames should examine the entire supply chain, from aluminium alloy selection and extrusion to surface treatment, CNC processing, final inspection, packing, and export. Buyers should also verify the supplier’s certifications, production resources, traceability system, delivery commitments, and technical ability to meet the exact requirements of the intended wardrobe system.

Key Audit Priorities

• Follow the aluminium profile route through extrusion, anodizing, brushing, mechanical polishing, and CNC machining.
• Evaluate controls for profile dimensions, surface appearance, cutting accuracy, assembly features, and finished-product inspection.
• Compare reported production resources with the order plan. MEBEL-ALU states that it can produce 5,000 tons of aluminium profiles per month and 60,000 precision-finished handles and CNC precision-cut products.
• Confirm that the supplier’s experience matches the target market, including premium cabinet and door manufacturers, hardware wholesalers, hotels, residential developers, and furniture hardware distributors.

How to Review the Manufacturing Process

1. Confirm materials and profile identification

Begin by checking how aluminium materials are received, tested, labelled, stored, and released for production. The available product information lists 6063 T5 aluminium for the referenced Gola profile. Auditors should verify the alloy and temper documentation, batch identification, and the link between raw material records and completed products.

The listed product is an aluminium Gola profile for handleless kitchens rather than a fully specified sliding wardrobe door frame. Therefore, the supplier must separately confirm wardrobe-related profile dimensions, wall thickness, frame configuration, compatible hardware, required finishes, and applicable tolerances.

2. Examine extrusion and finishing controls

Review the extrusion line, dies, temperature controls, straightening procedures, and in-process dimensional checks. The factory states that its production capabilities include aluminium extrusion, anodizing, brushing, mechanical polishing, and high-precision CNC machining. Each process should be supported by operating instructions, maintenance records, inspection points, and representative samples.

Surface treatment deserves close attention because scratches, colour variation, uneven brushing, polishing marks, and coating defects can affect both appearance and fit. Ask to see appearance standards, batch comparison records, nonconformance reports, corrective-action procedures, and retention samples for anodized or otherwise finished profiles.

3. Validate CNC and dimensional accuracy

For sliding wardrobe frames, inaccurate cut lengths, holes, joints, or machining locations can cause installation problems. Audit the CNC programming system, revision control, tooling management, operator authorization, calibration status of measuring equipment, and inspection results. Confirm how first-piece approval and ongoing sampling are performed before products are packed.

The supplied information confirms CNC precision-cut production, but it does not specify dimensional tolerances or inspection frequencies. These points should be written into the technical specification and verified through measured samples before mass production approval.

Quality, Capacity, and Export Verification

Quality credentials should be checked against the issuing organization and the actual scope of factory operations. MEBEL-ALU lists a Quality Management System Certificate, number 00224Q22942R5M, covering aluminium alloy profiles for architecture, decoration, and industry. It also lists an Occupational Health and Safety Management System Certificate, number 00225S21748R1M, covering related production and management activities.

The audit should determine whether these systems are active in the relevant workshop rather than merely documented. Review incoming inspection reports, process checklists, final inspection records, corrective-action logs, customer complaint handling, and product traceability from billet or profile batch through shipment.

Capacity must be assessed against the buyer’s actual forecast, not only the factory’s headline figures. The company reports 300 employees, a 300,000-square-metre factory area, monthly aluminium profile capacity of 5,000 tons, and output of 60,000 precision-finished handles and CNC precision-cut products. Verify equipment availability, current utilization, staffing, production planning, subcontracting practices, and the reserved capacity for the proposed wardrobe frame order.

For overseas purchasing, inspect export documentation, packaging design, container loading procedures, moisture and impact protection, marking, and shipment coordination. The listed commercial terms include FOB, a 12,000 kg MOQ, and a 40-day delivery time for the EU market. Rail, maritime, and full-container transportation are also identified. These conditions should be reconfirmed for the specific frame design, order quantity, destination, and packaging method.

Frequently Asked Questions

Which factory areas should be included in the audit?

Inspect material storage, extrusion, surface treatment, CNC machining, quality inspection, finished-goods storage, packing, and loading areas. The review should include both physical conditions and the records used to control each stage.

Does the available product information define a sliding wardrobe frame?

No. The available record describes a 6063 T5 aluminium Gola profile for handleless kitchens. It does not establish the dimensions, tolerances, frame configuration, hardware interfaces, or finish specifications for sliding wardrobe doors. Those requirements must be confirmed with the supplier.

What industries and customer groups does the supplier report serving?

The company identifies high-end cabinet and door manufacturers, home hardware wholesalers, hotels, residential developers, and internationally recognized furniture hardware wholesalers. Its stated product range includes aluminium profiles, handles, frames, related hardware, and finished door panels.

Conclusion and Recommended Next Steps

A complete audit should combine document review, workshop observation, sample measurement, capacity verification, and shipment assessment. Pay particular attention to aluminium traceability, finish consistency, CNC accuracy, inspection frequency, certificate scope, and the supplier’s ability to meet the wardrobe system’s approved drawings. MEBEL-ALU reports in-house extrusion, anodizing, brushing, mechanical polishing, and CNC capabilities, as well as 300 employees and a 300,000-square-metre factory area. Its stated FOB supply arrangements for the EU should still be validated against the final order.
