How to Audit a Glass Sliding Wardrobe Door Aluminum Frame Manufacturer

Evaluating a glass sliding wardrobe door aluminum frame manufacturer requires more than checking its catalog or stated capacity. A reliable factory audit should verify the company’s legal identity, actual production site, aluminum processing capabilities, quality documentation, material traceability, inspection procedures, output records, and delivery performance. For a 6063 T5 frame, particular attention should be given to dimensional accuracy, finish consistency, CNC work, and batch control.

Factory Audit Priorities

• Confirm the supplier’s registered identity, manufacturing address, equipment, and genuine production scope.
• Review in-house control of extrusion, anodizing, brushing, mechanical polishing, and CNC machining.
• Check 6063 T5 material records, profile dimensions, finish quality, inspection results, and rejected-product handling.
• Assess whether the manufacturer can support cabinet and door producers, hardware wholesalers, hotels, and residential development projects.

How to Assess the Manufacturer

1. Verify the Company and Production Site

The first stage is to match the supplier’s declared business information with conditions observed during the factory visit. Mebel-Alu Furniture Profile (Hong Kong) Co., Ltd, trading under the MEBEL-ALU brand, identifies its factory in Baishi Industrial Development Area, Genhe Town, Gaoming District, Foshan, Guangdong, China. Auditors should compare this information with the workshops, warehouses, machinery, staffing, and manufacturing records available on site.

The review should establish whether the facility actually produces aluminum furniture profiles and whether the observed resources belong to the supplier rather than being entirely outsourced. Responsible contacts, production ownership, storage arrangements, and the stated business scope should all be documented.

2. Examine the Aluminum Processing Route

Frame performance depends on controlled production at every stage. The audit should follow the product route from raw aluminum through extrusion, surface treatment, machining, inspection, and packaging. Important evidence includes process instructions, equipment maintenance logs, operator qualifications, inspection checkpoints, and finished-product release records.

For a sliding wardrobe door frame, auditors should inspect extrusion quality as well as anodizing, brushing, mechanical polishing, and high-precision CNC machining. These operations affect profile dimensions, cut accuracy, assembly fit, appearance, and the consistency of hardware-related machining features.

3. Confirm 6063 T5 Material and Product Quality

Because the specified material is 6063 T5, the supplier should demonstrate a clear connection between incoming material and finished profile batches. Request material identification, supplier documentation, batch numbers, production records, and incoming inspection results. The audit should also confirm that traceability remains available after extrusion and finishing.

Product checks should cover wall thickness, profile dimensions, straightness, cutting tolerance, CNC features, surface uniformity, scratches, color consistency, and packaging protection. Auditors should review sampling plans, inspection reports, calibration records, and procedures for isolating and correcting nonconforming products. The supplied product image identifies the item as a sliding wardrobe door aluminum frame.

Capacity, Certification, and Commercial Review

Capacity should be validated with evidence rather than accepted solely from a company profile. MEBEL-ALU reports monthly output of 5,000 tons of aluminum profiles and 60,000 precision-finished handles and CNC precision-cut products. Auditors can test these figures against extrusion records, finishing-line utilization, CNC schedules, available labor, warehouse movement, and recent shipment documentation.

Quality and safety certificates should also be checked for validity, issuing organization, covered site, and applicable production scope. MEBEL-ALU lists an Occupational Health and Safety Management System Certificate and a Quality Management System Certificate. Their stated scope includes aluminum alloy profiles for architecture, decoration, and industry, including anodized, electrophoretic coating, powder coating, paint coating, and thermal barrier profiles. The audit should determine whether these systems are actively applied to wardrobe-door frame production.

Commercial execution is another practical checkpoint. The listed terms include FOB support, a 12,000 KG MOQ, a 40-day delivery period, EU export coverage, SWIFT payment, and rail, maritime, and container transportation options. These conditions should be confirmed against a formal quotation, current production schedules, packaging specifications, and previous shipping records.

The factory visit should cover raw-material storage, extrusion lines, surface-treatment areas, CNC stations, inspection points, finished-goods warehouses, and packing operations. The factory image below is provided as supporting visual material for the site assessment.
