Non-Standard Aluminum-Profile CNC Customization

Non-standard aluminum-profile CNC customization is one of our core businesses, dedicated to providing customers with exclusive aluminum-profile design and manufacturing services beyond the scope of standard profile specifications.

Standard aluminum profiles have fixed cross-sectional shapes and dimensional specifications and cannot meet every equipment structure and assembly requirement. When equipment design requires an exclusive cross-section, special mounting slots, multi-cavity integration, large-size structural parts, or specific materials and tolerance grades, non-standard customization is the only viable choice.

Located in Qingpu, Shanghai, Shanghai Chuangsi Aluminum Co., Ltd. has full-process production capability from mold design, extrusion and heat treatment to CNC precision machining and surface treatment. We accept minimum orders of 50kg/order, supporting drawing-based customization, sample-based customization, R&D sampling and small-to-medium batch production. After the customer provides drawings or samples, our engineering department issues a technical proposal and quotation within 48 hours, providing professional optimization advice on cross-section structure, tolerance grade and material selection.

Mold development uses H13 hot-work die steel, with samples for standard cross-sections in 7-10 days; the mold fee is fully refunded once the agreed mass-production quantity is reached. Extrusion capacity covers 600T to 12000T (partner production lines), capable of producing ultra-large profiles with a circumscribed circle diameter of 600-700mm and weight per meter from 0.05kg to 80kg. Extrusion dimensional tolerance is stably controlled within ±0.02mm to ±0.04mm, and CNC machining accuracy is ±0.01-0.005mm. We deliver one-stop full-process from requirement evaluation, cross-section design and mold development to extrusion, CNC finishing and surface treatment (extrusion uses partner production lines).

Core Machining Capabilities:

1. Exclusive cross-section design and optimization: We design exclusive aluminum-profile cross-sectional shapes according to the customer's equipment structure and assembly requirements. Functional zones such as mounting clips, guide slots, cable-running cavities, cooling fins and sealing grooves can be integrated and formed in one extrusion, reducing subsequent machining operations.

2. Large/ultra-large cross-section profile extrusion: Extrusion capacity covers 600T to 12000T (partner production lines), capable of producing ultra-large profiles with a circumscribed circle diameter of 600-700mm and weight per meter from 0.05kg to 80kg.

3. Precision extrusion of complex cross-sections: We use CAE simulation to model metal flow and solve problems such as uneven flow velocity and shortage of material. Complex cross-sections such as multi-cavity structures, deep-cavity thin walls, asymmetrical shapes and thin-wall large cross-sections can all be formed in one extrusion.

4. Precision CNC post-machining: Equipped with five-axis/three-axis CNC machining centers, CNC lathes and end-face milling machines, we complete the full range of operations including milling, turn-mill compound machining, drilling and tapping, precision cutting and end-face milling.

5. Full-process one-stop delivery: Full-process one-stop delivery from mold design, extrusion and CNC finishing to surface treatment (extrusion uses partner production lines); the customer only needs to provide drawings.

FAQ (Frequently Asked Questions)

Q1: When is non-standard aluminum-profile customization needed?

A: Standard aluminum profiles have fixed cross-sectional shapes and dimensional specifications and cannot meet every equipment structure requirement. You need non-standard customization when your equipment requires any of the following: ① special cross-sectional shapes (cross-sections not available in standard profiles); ② special dimensional specifications (standard profile dimensions too small or too large); ③ special material requirements; ④ special tolerance requirements; ⑤ multi-cavity or functional integration; ⑥ large-cross-section structural parts.

Q2: What is the MOQ for non-standard customization?

A: The MOQ is 50kg. We support small-batch sampling, R&D trial production and small-to-medium batch production, especially suitable for trial-production needs during the equipment R&D stage.

Q3: How long does non-standard customization take from order to sample?

A: Samples for standard cross-sections take 7-10 days. Complex cross-sections are assessed according to structural complexity and generally take 10-15 days for samples. Mold development uses H13 hot-work die steel to ensure mold life and profile quality.

Q4: Is the mold fee refundable?

A: The mold fee is fully refunded once the agreed mass-production quantity is reached. The specific mass-production quantity is determined by the cross-section complexity and dimensions of the profile and is stated together with the quotation.

Q5: What is the maximum cross-section of aluminum profile that can be customized?

A: Maximum circumscribed circle diameter is 600-700mm, and maximum weight per meter is 80kg. The specific cross-sectional dimensions are comprehensively assessed based on the profile structure and equipment capability.

Q6: What aluminum-profile materials can be customized in non-standard customization?

A: We can customize all grades of aluminum alloy, including 6061-T6, 6063-T5, 6005-T6, 6082-T6, 7075-T5 and 1070 high-thermal-conductivity aluminum. Different materials suit different scenarios; we recommend the optimal material solution based on your usage requirements.
