Sliding Wardrobe Door Frame Factory Audit Checklist

Auditing a supplier of sliding wardrobe door frames requires more than checking a few finished samples. Buyers should evaluate the factory's aluminium profile capabilities, finishing consistency, machining accuracy, quality controls, production resources, and export execution. The audit should also confirm that the supplier can reliably produce slim aluminium frames designed for glass door and furniture applications.

Priority Checks for a Sliding Wardrobe Frame Supplier

Start by confirming that the audited site genuinely produces the required aluminium furniture profiles. For sliding wardrobe projects, the factory should demonstrate experience with aluminium glass door systems, sliding wardrobe systems, cabinet frame profiles, and associated furniture hardware applications.

Mebel-Alu Aluminium presents slim aluminium frame profiles for glass doors as part of its furniture aluminium portfolio. During the visit, compare physical samples with approved drawings and project specifications. Pay particular attention to frame cross-section, wall thickness, straightness, joint design, glass receiving dimensions, and compatibility with the selected sliding door hardware.

Assess Manufacturing Control from Extrusion to CNC Processing

A reliable wardrobe door frame depends on process control throughout production, not solely on final inspection. The factory states that it operates aluminium extrusion, anodizing, brushing, mechanical polishing, and high-precision CNC machining in-house. These capabilities should be checked on the production floor rather than accepted only from company documentation.

Aluminium Extrusion and Profile Geometry

Review the extrusion workflow, tooling management, alloy material identification, dimensional inspection, and handling of nonconforming profiles. Confirm that the factory measures critical dimensions needed for glass doors and sliding wardrobe assemblies, including slot width, frame depth, straightness, twist, and cutting allowances. Ask to see inspection records for comparable profile models and recent production batches.

Surface Treatment and Appearance Standards

Anodizing, brushing, and mechanical polishing have a major effect on the appearance of aluminium wardrobe frames. Inspect how the supplier controls finish samples, color or texture references, surface acceptance criteria, and batch-to-batch consistency. The audit should also cover protective film application, rack marks, scratch prevention, storage conditions, and packing methods, since cosmetic damage can occur after the finishing line.

CNC Accuracy and Component Readiness

Where door frames require drilled holes, mitre cuts, connector positions, handle features, or other prepared details, examine CNC equipment, programming control, measuring tools, and first-piece approval practices. Verify that machined profiles can be assembled with the intended glass panels, rollers, tracks, and connecting hardware without excessive adjustment on site.

Review Quality Systems and Workplace Implementation

Certificates are useful starting points, but an audit should establish whether their requirements are active in daily production. The available factory data lists a Quality Management System Certificate, number 00224Q22942R5M, for aluminium alloy profiles used in architecture, decoration, and industry. Its stated coverage includes anodized profiles, electrophoretic coating profiles, powder coating profiles, paint coating profiles, and thermal barrier profiles.

Confirm that this quality system applies to the physical facility being audited and to the product category proposed for the sliding wardrobe order. Review incoming material checks, in-process inspections, final quality reports, corrective action records, customer complaint procedures, and product traceability. A supplier should be able to link finished frame bundles to relevant material, processing, and inspection records.

The factory also lists an Occupational Health and Safety Management System Certificate, number 00225S21748R1M. Its scope covers aluminium alloy profile production for architecture, decoration, and industrial applications, along with related management activities. Inspect whether safety procedures are visible and consistently applied around extrusion equipment, finishing operations, machining stations, material transport, and packing areas.

Validate Capacity, Scheduling, and Delivery Commitments

Production scale must be assessed against the actual order mix, rather than relying on headline capacity figures alone. The company reports monthly output of 5,000 tons of aluminium profiles, as well as 60,000 units of precision-finished handles and CNC precision-cut products. A separate FOB supply record identifies 6,000 tons of monthly capacity and a 40-day delivery time for the EU market.

Because these figures are presented under different company data categories, ask the supplier to define exactly what each number includes. Confirm the product range, current utilization rate, number of operating production lines, committed customer orders, and capacity reserved for the proposed project. Delivery planning should account for extrusion, finishing, machining, inspection, packing, container loading, and export documentation.

Check Project Compatibility and Supply Chain Support

The listed customer applications include high-end cabinet and door manufacturers, home hardware wholesalers, hotel projects, residential developers, and furniture hardware distributors. Mebel-Alu also describes a one-stop aluminium home furnishing offering that includes aluminium handles, frame systems, compatible hardware, and finished door panels.

For a sliding wardrobe door program, determine whether the supplier can coordinate profile selection with glass specifications, door panel requirements, fittings, and installation expectations. This is especially important when the buyer requires matched finishes across frames, handles, and accessory components. Request samples or assembly demonstrations to verify that the proposed system functions as intended.

Confirm Export and Logistics Responsibilities

For international wardrobe door projects, logistics performance is part of supplier qualification. The company identifies Europe, South America, Southeast Asia, and the Middle East as primary markets, with an export ratio reported at 100 percent. Its recorded business model is FOB, supported by rail transport, sea freight, and full-container shipping arrangements.

Before order approval, confirm the agreed Incoterm, export port, packaging specification, bundle protection, container loading method, shipping documents, insurance responsibilities, and the point at which risk transfers to the buyer. Frame profiles with visible finishes and precision-machined ends need transport packaging that prevents movement, abrasion, moisture exposure, and deformation.

Frequently Asked Questions

Which processes are most important when auditing sliding wardrobe door frames?

Focus on extrusion, anodizing, brushing, mechanical polishing, and CNC machining. Together, these stages determine profile dimensions, visual finish, machining precision, and the final frame's ability to work with glass and sliding door hardware.

What certificates should be reviewed at the factory?

The listed documents include the Quality Management System Certificate 00224Q22942R5M and the Occupational Health and Safety Management System Certificate 00225S21748R1M. Verify their validity, scope, audited site, and supporting implementation records.

Why should the reported capacity be clarified?

The company information lists 5,000 tons of monthly aluminium profile capacity in one field and 6,000 tons in a separate FOB business record. The supplier should explain the scope, market relevance, and calculation basis of each figure before the buyer uses it for purchasing or delivery planning.

Conclusion

An effective sliding wardrobe door frame audit examines actual production capability, profile and finish consistency, CNC control, quality records, safety practices, capacity allocation, and shipping execution. The listed Mebel-Alu information supports a review of in-house aluminium processing and FOB supply for export markets, but buyers should verify all claims at the relevant production site.

In particular, confirm the applicability of the listed certifications, inspect the full flow from extrusion through packing, and obtain written clarification of the differing capacity figures and delivery assumptions. This approach provides a more dependable basis for sourcing aluminium frames for sliding wardrobe door projects.
