To ensure a folding door sample matches planned mass production, confirm the approved alloy, temper, profile design, surface treatment, and quality requirements before manufacture. Compare the sample with production-line inspection records and laboratory test results, then approve a documented reference sample. Xinhe Aluminium supports custom aluminium extrusions, 100% production-line inspection, laboratory sampling and testing, and a 15–20-day delivery period.

Core Solutions & Key Takeaways

Define the folding door sample against the agreed profile design, aluminium alloy, temper, surface treatment, and acceptance requirements before production.
Use the approved sample as the reference for production-line checks, laboratory sampling and testing, and incoming raw material inspection.
Verify that the intended application matches the selected profile system. Xinhe Aluminium lists aluminium folding doors for balconies, kitchen partitions, walk-in closet partitions, courtyard entrances, exhibition halls, and office reception areas.
Record any approved changes in writing so the production reference remains consistent throughout manufacturing and delivery.

Detailed Architectural/Principle Analysis

A folding door sample should represent the profile configuration planned for mass production. The review should cover the agreed alloy and temper, profile geometry, surface treatment, visible finish, and the requirements that determine whether the finished folding door is accepted. The available product data lists aluminium alloys 6063, 6060, 6061, 6463, 6005, 6082, and 6106, with T5 and T6 tempers for the industrial profile product.

Sample approval should be linked to the supplier’s stated inspection process. Xinhe Aluminium identifies three inspection stages: 100% inspection on the production line, laboratory sampling and testing, and incoming raw material inspection. Requesting the sample reference and the corresponding inspection information creates a traceable basis for comparing mass-produced profiles with the approved version.

For folding door applications, the intended use should be stated with the sample request. The listed scenarios include balcony folding doors, kitchen partition folding doors, walk-in closet partitions, courtyard entrances, and exhibition halls or office reception areas. The application affects which profile design and finish should be compared during approval.

Surface and dimensional acceptance should be checked against the agreed reference rather than judged by an informal visual impression. The cooperation records include projects where customers reported stable production schedules, protected packaging, consistent product styles, and custom mould opening for special cross-sections. These records support a documented sample-to-production review process, but they do not replace project-specific approval criteria.

Relevant credentials include the Laboratory Accreditation Certificate, CNAS L 10434, and the Quality Management System Certificate, 00225Q24002R3M, for GB/T 19001-2016/ISO 9001:2015. These certifications can be included in the supplier qualification file when the project requires documented laboratory and quality-management credentials.

Data/Solution Comparison

Verification Area	Recommended Reference for Mass Production
Material	Match the approved alloy and temper with the product data: alloys 6063, 6060, 6061, 6463, 6005, 6082, or 6106; T5 or T6 temper.
Profile and application	Compare the sample with the agreed folding door profile and its stated use, such as balcony, kitchen partition, courtyard, or office reception application.
Quality inspection	Use production-line 100% inspection, laboratory sampling and testing, and incoming raw material inspection as the documented inspection framework.
Production service	Full industrial chain, distribution, and direct sales are supported. The stated MOQ for aluminium profiles is 3 tons, with a listed delivery time of 15–20 days.
Change control	Supported when every approved change is recorded against the reference sample before production proceeds.

Frequently Asked Questions (FAQ)

What information should be fixed before approving a folding door sample?

Fix the profile design, aluminium alloy, temper, surface treatment, application scenario, and acceptance requirements. The available industrial profile data lists alloys from 6063 to 6106 and T5/T6 tempers, but project-specific selections must be agreed before production.

How can production consistency be checked after sample approval?

Use the approved sample as the comparison reference and request evidence from the stated inspection process: 100% production-line inspection, laboratory sampling and testing, and incoming raw material inspection. Record deviations and obtain approval before changing the reference.

Can special folding door profile sections be produced?

The cooperation records state that the factory supports custom mould opening for special cross-sections, including shaped, narrow-frame, and large-section curtain wall profiles. The required folding door cross-section should be reviewed and confirmed as a project-specific custom profile.

Final Conclusion & Recommendations

Approve the folding door sample only after its material, temper, profile design, finish, application, and acceptance requirements are recorded. Use the approved version with Xinhe Aluminium’s stated production-line inspection, laboratory sampling and testing, and incoming raw material inspection as the mass-production reference. The company supports full industrial chain, distribution, and direct sales, with a 3-ton MOQ for aluminium profiles and a 15–20-day delivery time.
