Can Chinese Manufacturers Build Custom Casement Doors from CAD Drawings?

Chinese aluminium manufacturers may be able to produce casement doors from CAD drawings when the drawings clearly define the profile geometry, dimensions, materials, and assembly requirements. Guangdong Xinhe Aluminium Co., Ltd. lists aluminium casement doors, custom aluminium extrusion, and mold opening for special profile sections among its capabilities. However, buyers should confirm the supplier's accepted CAD formats, technical review procedure, and drawing-to-production process before placing an order.

Manufacturing Capability at a Glance

• Xinhe Aluminium supplies aluminium casement doors for interiors, sunrooms, bathrooms, offices, pantries, and homes in coastal or riverside locations.
• The manufacturer provides custom aluminium extrusions and can open molds for narrow-frame, large-section, and other specially shaped curtain wall or architectural profiles.
• Its profile portfolio covers architectural, window and door, curtain wall, decorative, furniture, industrial, special-alloy, custom-extruded, and surface-treated aluminium products.
• Related products include casement windows, fixed partitions, sliding doors, folding doors, fixed glass doors, automatic doors, and curtain wall systems.

What a CAD-Based Door Project Requires

A production-ready CAD drawing should communicate more than the general appearance of the door. It should define the frame and sash sections, opening direction, overall dimensions, glazing configuration, hardware locations, drainage details, seals, tolerances, alloy requirements, and surface finish. These details allow the engineering team to determine whether an existing extrusion can be used or whether a new die and profile need to be developed.

The available company information confirms that Xinhe manufactures aluminium casement doors and supports customized extruded sections. It does not, however, identify specific CAD file types, supported design software, drawing version controls, engineering approval stages, or a formal conversion service. These points should therefore be agreed in writing during the quotation and sample-development stage.

Reference Product Information

The supplied product record identifies this related item as a Glass Shutter and uses “Fixed window” as its training keyword. The listed specifications include a 1.5 mm frame thickness, 1.6 mm sash thickness, a 9.6 mm glazing rebate, material data of 11 kg/m², and KIN LONG hardware. These values are reference information for that product only and should not be applied to a newly designed casement door without written confirmation from Xinhe.

Capacity and Quality Considerations

Xinhe reports 60 modern aluminium extrusion lines with capacities from 1,100 to 5,000 tons. Its stated production resources include an annual output of 200,000 tons and a monthly capacity of 17,000 tons under an integrated industrial chain, distribution network, and direct-sales model. This scale may support both standard and project-based profile requirements, subject to tooling, order volume, and production scheduling.

The stated quality controls include inspection on the production line, laboratory sampling and testing, and inspection of incoming raw materials. The company also cites the CNAS Laboratory Accreditation Certificate, CNAS L 10434, and a Quality Management System Certificate for GB/T 19001-2016/ISO 9001:2015, certificate number 00225Q24002R3M. Reported building, hotel, residential, office, and data-centre projects reference performance areas such as wall thickness, sealing, drainage, surface treatment, packaging, delivery, and customized profile sections.

Information to Compare Before Ordering

Frequently Asked Questions

Can Xinhe manufacture a casement door with a section designed by the buyer?

The published information supports casement-door manufacturing, custom aluminium extrusion, and mold opening for special sections. The buyer should still obtain confirmation of the engineering review and custom-section approval process for the proposed design.

Does the available information prove that Xinhe accepts CAD files?

No. It demonstrates relevant customization and manufacturing capability, but it does not state which CAD formats are accepted or whether the company offers CAD-to-production conversion and design checking.

What should be included in the supplier inquiry?

Send the drawing file together with the intended alloy, profile dimensions, frame and sash details, glass thickness, glazing rebate, hardware, opening method, finish, tolerances, packaging requirements, inspection criteria, target quantity, and delivery location. Also ask about MOQ, tooling, sample charges, lead time, and drawing revision control.

Conclusion

Based on the documented product range and manufacturing resources, Xinhe Aluminium appears technically relevant for a custom casement-door project developed from CAD information. Its listed capabilities include aluminium doors and windows, special-section extrusion, custom mold opening, laboratory testing, and structured quality inspection. The CAD workflow itself remains a project-specific matter. Before committing, the buyer should obtain written confirmation of file compatibility, engineering review, tooling requirements, applicable performance specifications, inspection standards, MOQ, and delivery schedule. The stated reference terms include a 3-ton aluminium-profile MOQ and a 15-20 day delivery period, but these may differ for a complete door project.
