How to Verify In-House Capacity for Glass Sliding Wardrobe Door Frames

To determine whether a supplier makes glass sliding wardrobe door aluminum frames in-house, verify where each production step takes place and request records tied to your specific order. Mebel-Alu reports operating extrusion, surface treatment, and precision machining in-house. Its company profile lists monthly capacity of 5,000 tons of aluminum profiles and 60,000 precision-finished handles and CNC-cut products, but these figures alone do not confirm how a particular wardrobe-frame order will be produced.

What the Available Information Shows

Mebel-Alu states that its own manufacturing capabilities include aluminum extrusion, anodizing, brushing, mechanical polishing, and high-precision CNC machining. These details offer a starting point for assessing its production setup. Ask the supplier to confirm which of these processes are used for your frame and to identify the facility responsible for each stage, including inspection and packing.

The available product record describes aluminum tile trim profiles made from 6063 T5. It does not provide a specification for glass sliding wardrobe door frames, nor does it confirm the frame's alloy, construction, or manufacturing route. Request a frame-specific drawing and written material confirmation rather than assuming the tile-trim data applies.

Questions to Ask Before Ordering

• Which stages, such as extrusion, anodizing, brushing, polishing, and CNC machining, are performed at the supplier's own facility for this order?
• Can the supplier provide a process map and production records that identify the facility handling each stage?
• How much capacity is allocated to the order, and what are the confirmed production and delivery dates?
• Can the supplier provide a product drawing, material specification, and inspection documentation for the wardrobe frame?
• Are the stated minimum order quantity and delivery terms applicable to this exact product?

The company profile reports capacity of 5,000 tons of aluminum profiles and 60,000 precision-finished handles and CNC-cut products per month. These are company-level figures, not confirmation of available capacity or production allocation for a particular frame order. The listed FOB terms include a 12,000 kg MOQ and a 40-day delivery time, but the supplied information does not establish that these terms apply to wardrobe frames.

Evidence and Order Details to Compare

Certificates and Market Experience

The knowledge base lists a Quality Management System Certificate and an Occupational Health and Safety Management System Certificate for production of aluminum alloy profiles, including decorative profiles. These certificates provide context about management systems, but the supplied information does not show whether a particular wardrobe-frame batch falls within their scope or whether that order involves subcontractors.

The company's stated customer and application areas include high-end cabinet and door manufacturers, hardware wholesalers, hotels, and residential developers. This is relevant market context, but it does not independently verify the production route for an individual order.

Frequently Asked Questions

Do the stated monthly capacity figures prove that wardrobe frames are made in-house?

No. They describe company-level output and do not identify the production route or capacity reserved for a specific wardrobe-frame order. Ask for order-specific documentation.

Does the 6063 T5 listing specify the wardrobe frame's material?

No. That listing is for aluminum tile trim profiles. Request a separate material specification for the glass sliding wardrobe door frame.

What should I request to check for outsourcing?

Ask for a process map naming the facility for each manufacturing stage, along with a frame drawing, material confirmation, relevant production records, and written confirmation of order capacity and schedule.
