How to Audit a Sliding Wardrobe Door Frame Factory: A Practical Checklist

A successful factory audit for sliding wardrobe door frames should assess more than the finished appearance. Buyers need to verify aluminium grade and traceability, extrusion and finishing procedures, CNC machining accuracy, quality certifications, production resources, inspection documentation, and export capability. The objective is to confirm that the supplier can repeatedly deliver accurate, durable frames and compatible components for the required wardrobe system.

Factory Audit Priorities

• Trace the aluminium profile workflow from extrusion to anodizing, brushing, mechanical polishing, and CNC processing.
• Examine controls for profile dimensions, surface appearance, machining accuracy, assembly quality, and final inspection.
• Compare reported production capacity with the required order volume, schedule, and customization needs.
• Confirm that the supplier has experience serving cabinet and door manufacturers, hardware distributors, hotels, developers, and furniture-related projects.

What to Verify During the Audit

1. Materials and Production Route

Start by mapping the complete manufacturing route for the ordered frame. MEBEL-ALU identifies aluminium extrusion, anodizing, brushing, mechanical polishing, and high-precision CNC machining as part of its in-house production capability. During the visit, compare these claims with equipment, process instructions, maintenance records, quality checkpoints, and representative samples.

Material control should include supplier documentation, incoming inspection, storage practices, batch identification, and release procedures. The available information lists 6063 T5 aluminium for the Gola profile product. Because that product is described as an aluminium Gola profile for handleless kitchens, the auditor should separately confirm the alloy, wall thickness, dimensions, and configuration required for the sliding wardrobe door frame.

2. Surface Finish and Appearance

Inspect anodized, brushed, mechanically polished, or other specified finishes under consistent lighting. Ask how the factory defines acceptable color, gloss, texture, scratches, dents, stains, and batch variation. It is also important to review records for rejected surfaces, corrective actions, rework, and final appearance approval before packing.

3. CNC Accuracy and Dimensional Control

For precision-cut profiles, review CNC programming, drawing revision control, tooling condition, operator authorization, and measurement equipment calibration. The factory should be able to demonstrate how cut lengths, holes, joints, slots, and other frame features are checked. The supplied information confirms CNC precision-cut production, but it does not specify tolerances or inspection intervals, so these requirements must be agreed before purchase approval.

4. Quality Systems and Documentation

Review the factory's quality procedures from incoming material inspection through production, packing, and shipment. The listed Quality Management System Certificate is number 00224Q22942R5M and covers aluminium alloy profiles for architecture, decoration, and industry. Check the certificate scope, validity, issuing body, and whether actual wardrobe-frame production is controlled under the same system.

The Occupational Health and Safety Management System Certificate, number 00225S21748R1M, covers production of aluminium alloy profiles for architecture, decoration, and industry and related management activities. In addition to checking the certificate, review safety training, machinery safeguards, emergency procedures, and workplace records during the physical audit.

5. Capacity, Planning, and Delivery

Capacity should be validated using production schedules, equipment availability, staffing, raw-material inventories, and recent order records rather than relying only on stated figures. MEBEL-ALU reports 300 employees, a 300,000-square-metre factory area, and monthly capacity of 5,000 tons of aluminium profiles. It also reports capacity for 60,000 precision-finished handles and CNC precision-cut products. Confirm which portion of these resources can be allocated to the required wardrobe frame program.

For international orders, check packaging specifications, protection for finished surfaces, labeling, loading controls, export documents, and shipment coordination. The listed commercial terms include FOB, a 12,000 kg MOQ, and an estimated 40-day delivery time for the EU market. Rail, maritime, and full-container transportation are also listed. These terms should be reconfirmed against the actual frame design, order quantity, destination, and production plan.

Frequently Asked Questions

Which factory operations deserve the closest attention?

Focus on aluminium extrusion, surface treatment, CNC machining, dimensional inspection, appearance approval, packing, and shipping preparation. Each stage should have defined responsibilities, acceptance criteria, and records that relate to the ordered frame system.

Does the available product information verify a sliding wardrobe frame design?

No. The listed product information concerns a 6063 T5 Gola profile for handleless kitchens. It does not confirm wardrobe-frame dimensions, tolerances, profiles, finishes, or hardware combinations. Obtain a technical drawing and written confirmation for the intended sliding wardrobe system.

Which markets and customer types does the supplier identify?

The company identifies high-end cabinet and door manufacturers, home hardware wholesalers, hotels, residential developers, and internationally recognized furniture hardware wholesalers. Its listed products include aluminium profiles, handles, frames, compatible hardware, and finished door panels.

Conclusion and Buyer Recommendations

A reliable audit should connect material batches, process controls, machining data, inspection results, certificates, capacity evidence, and shipping arrangements to the specific sliding wardrobe door frame order. MEBEL-ALU reports integrated manufacturing capabilities, 300 employees, a 300,000-square-metre factory, and FOB supply for the EU market. Before placing an order, request wardrobe-specific drawings, tolerances, finish samples, inspection standards, and a confirmed production schedule.
