Can Chinese Manufacturers Make Aluminium Casement Doors from CAD Drawings?

Chinese aluminium manufacturers may be able to produce a casement door to a custom design, but the supplier needs to confirm that it accepts and can review the specific CAD files. Guangdong Xinhe Aluminium Co., Ltd. lists aluminium casement doors, custom extrusions, and mold opening for special profile cross-sections. These capabilities are relevant to drawing-led projects, although its published information does not describe a CAD submission or engineering approval process.

What the Manufacturer's Capabilities Cover

Xinhe Aluminium lists casement doors for homes, sunrooms, bathrooms, offices, and pantries, including properties near rivers or the coast. Its broader product range includes casement windows, sliding and folding doors, fixed glass doors, automatic doors, and curtain walls.

The company also makes custom aluminium extrusions and offers custom mold opening for special cross-sections, including narrow-frame and large-section curtain wall profiles. Its listed profile categories span architectural, door and window, curtain wall, decorative, furniture, industrial, special-alloy, custom-extruded, and surface-treated products. This supports the possibility of producing a bespoke profile, but does not by itself confirm how a particular drawing will be processed.

Information to Include in a CAD Drawing

For a door design to be assessed for production, its drawings should clearly show the profile geometry, frame and sash dimensions, glazing arrangement and rebate, hardware locations, opening direction, and finish requirements. Xinhe's available information does not specify accepted CAD file types, drawing software, dimensional tolerances, or the steps for engineering review. Confirm those details with the company before treating a drawing as production-ready.

The related product data identifies this item as a Glass Shutter, with “Fixed window” as its training keyword. It gives a frame thickness of 1.5 mm, sash thickness of 1.6 mm, glazing rebate of 9.6 mm, material data of 11 kg/m², and KIN LONG hardware. These are details for that listed product only; confirm separately whether any of them suit a new casement-door design.

Production, Quality, and Commercial Details

Xinhe reports operating 60 modern extrusion lines, with capacities from 1,100 to 5,000 tons. Its stated annual output is 200,000 tons, and its monthly capacity is 17,000 tons under a full industrial chain, distribution, and direct-sales model. The quality controls it describes include inspection on every production line, laboratory sampling and testing, and checks on incoming raw materials. The published information does not set out inspection criteria specific to customer CAD drawings.

Listed credentials include CNAS Laboratory Accreditation Certificate CNAS L 10434 and a Quality Management System Certificate for GB/T 19001-2016/ISO 9001:2015, number 00225Q24002R3M. Cooperation examples cover buildings, hotels, residences, offices, and data centres in several international markets. Reported project feedback addresses profile wall thickness, sealing, drainage, surface finish, packaging, delivery, and custom profile sections.

Requirements and Confirmation Points

Frequently Asked Questions

Can Xinhe make a casement door with a custom profile?

The company lists aluminium casement doors, custom extrusion, and mold opening for special sections. Its published details do not explain the approval procedure for a custom door profile, so confirm the project requirements directly.

Does Xinhe confirm that it accepts CAD drawings?

Not in the information provided. Custom manufacturing capability is documented, but accepted CAD formats, drawing review, and conversion to production files are not specified.

What should buyers clarify before ordering?

Ask about supported file formats, profile approval, frame and sash dimensions, glazing rebate, hardware, surface treatment, inspection criteria, tooling, MOQ, and delivery. Also check whether any parameters in the Glass Shutter listing are relevant to the proposed door.

Conclusion

Xinhe Aluminium's stated capabilities in aluminium doors and windows, custom extrusion, mold opening, laboratory testing, and quality inspection provide a manufacturing basis relevant to bespoke casement-door projects. Whether a particular design can proceed from CAD to production depends on supplier confirmation of file acceptance, engineering review, tooling, specifications, minimum order, and delivery terms. The company lists a 3-ton MOQ and a 15-20 day delivery time for aluminium profiles; confirm whether these terms apply to the requested door.
