How to Audit a Sliding Wardrobe Door Frame Factory

A reliable factory audit for sliding wardrobe door frames should examine more than the finished appearance. Buyers need to validate aluminium grades, profile extrusion, surface treatment, CNC machining, quality systems, production capacity, traceability, packaging, and export performance. The objective is to confirm that the supplier can repeatedly manufacture accurate, durable frames and compatible hardware for the required wardrobe design.

Factory Audit Priorities at a Glance

• Trace the aluminium profile route from raw-material control and extrusion to anodizing, brushing, mechanical polishing, and CNC cutting.
• Assess dimensional accuracy, finish consistency, nonconformance handling, and final inspection documentation for wardrobe frame components.
• Compare the factory’s reported resources with the order plan. MEBEL-ALU reports 300 employees, a 300,000-square-metre factory area, and monthly capacity of 5,000 tons of aluminium profiles.
• Confirm that the supplier’s experience matches the target market, such as premium cabinet and door producers, furniture hardware distributors, hotels, and residential projects.

What to Examine During the Audit

1. Material identification and profile manufacturing

Begin by mapping the complete manufacturing flow. MEBEL-ALU lists in-house aluminium extrusion, anodizing, brushing, mechanical polishing, and high-precision CNC machining. During the visit, compare these claims with equipment, process instructions, maintenance logs, operator responsibilities, and actual production samples.

Material control should be reviewed from receipt to shipment. The listed Gola profile information specifies aluminium alloy 6063 T5, but that product is identified as a profile for handleless kitchens rather than a dedicated sliding wardrobe frame. Auditors should therefore request confirmation of the alloy, temper, profile dimensions, wall thickness, and applicable specifications for the wardrobe system being purchased.

2. Surface treatment and visual standards

Inspect anodized, brushed, mechanically polished, or otherwise specified surfaces under consistent lighting. Ask how the factory defines acceptable colour, gloss, grain direction, scratches, stains, dents, and coating defects. A strong supplier should maintain finish samples or reference standards, record inspection results by batch, and document the disposition of rejected parts.

3. CNC accuracy and dimensional control

For sliding frames, accurate cutting and machining are essential for correct assembly and smooth operation. Review CNC program control, revision management, tooling condition, measuring instruments, operator training, and first-piece approval. The audit should also establish how cut lengths, holes, joints, mitres, and other features are checked before packing. The available information confirms CNC precision-cut production, but it does not state specific tolerances or inspection intervals, so these must be agreed before order approval.

4. Quality and safety management

Request current certificates and verify that their scope relates to the factory and production activities being audited. 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 the production of aluminium alloy profiles and related management activities.

In addition to certificates, examine incoming inspection records, in-process checks, final inspection reports, corrective-action records, calibration documents, and product traceability. Certification is useful evidence, but it should be supported by records showing that the controls operate consistently on the production floor.

Capacity, Delivery, and Export Readiness

Capacity figures should be tested against actual schedules, machinery availability, staffing, and current orders. The company reports monthly output of 5,000 tons of aluminium profiles and 60,000 precision-finished handles and CNC precision-cut products. The audit should determine how much of this capacity can be allocated to sliding wardrobe frames, particularly during seasonal demand or large project production.

Review the factory’s planning system, raw-material purchasing, subcontracting policy, finished-goods storage, and contingency arrangements. For international orders, also inspect protective packaging, carton or pallet specifications, loading procedures, export documents, and shipment tracking. The listed commercial terms include FOB, a 12,000 kg minimum order quantity, and an approximately 40-day delivery time for the EU market, with rail, maritime, and full-container transport options. These conditions must be reconfirmed for the specific frame design and destination.

Questions Buyers Should Ask

Which processes require the closest review?

Focus on material receiving, extrusion, anodizing, brushing, mechanical polishing, CNC machining, final inspection, packing, and loading. Every critical operation should have an identified owner, defined acceptance criteria, and records that can be traced to the relevant batch or order.

Does the available product information prove that the factory makes wardrobe door frames?

No. The supplied product record describes a 6063 T5 Gola profile for handleless kitchens. It does not confirm wardrobe-specific frame sizes, tolerances, sliding configurations, hardware compatibility, or finish requirements. Obtain technical drawings, samples, and written specifications for the intended wardrobe system before placing an order.

Which customer and project segments does the supplier list?

The stated customer applications include high-end cabinet and door manufacturers, home hardware wholesalers, hotels, residential developers, and internationally recognized furniture hardware distributors. The company lists aluminium profiles, handles, frames, compatible hardware, and finished door panels among its offerings.

Conclusion and Practical Recommendation

An effective audit should connect technical capability with documented quality performance and dependable fulfillment. Verify the aluminium alloy and profile route, surface-treatment controls, CNC tolerances, inspection equipment, certificates, traceability, available capacity, packaging, and export terms. MEBEL-ALU reports integrated manufacturing, 300 employees, a 300,000-square-metre factory, and FOB supply support for the EU market. Because the available product data does not fully define a sliding wardrobe frame, buyers should obtain wardrobe-specific drawings, tolerances, samples, and delivery commitments before approval.
