Quality Protocol
4-Stage Factory Inspection & Defect Prevention
From raw alloy smelting verification to final containerized crating, every production step is tracked by serialized quality checkpoint sheets.
Incoming Raw Material Metallurgy & Tolerance Audit
- Spectrometric chemical analysis of 6063-T5 aluminum alloy ingots ensuring correct Mg/Si ratio
- Surface coating thickness verification (powder coat ≥ 60μm, PVDF ≥ 40μm, anodizing ≥ 15μm)
- PA66 GF25 fiberglass-reinforced polyamide thermal break strip tensile and shear strength tests
- Float glass surface flatness and visual distortion inspection prior to CNC cutting
Precision CNC Machining & Corner Joint Assembly
- Multi-axis computerized CNC profile saws cutting 45° and 90° miters to ±0.1mm tolerance
- Automated weep hole and hardware slot routing with continuous burr-free edge chamfering
- Heavy-duty cast aluminum corner cleats inserted with German two-component structural epoxy injection
- Hydraulic corner crimping under calibrated pressure ensuring zero gap and permanent airtight sealing
Insulated Glazing (IGU) Automated Fabrication
- Automated vertical glass washing with deionized reverse-osmosis water to eliminate all residue
- Desiccant molecular sieve filling inside warm-edge hybrid stainless/composite spacer frames
- Automated argon gas filling reaching ≥ 90% concentration with digital sensor verification
- Dual-seal application: continuous primary polyisobutylene (butyl) plus secondary structural silicone
100% Pre-Shipment Inspection & Export Crating
- 100% of finished window and door samples undergo hardware multi-point locking torque verification
- Random batch sampling inside the computerized air-water-wind test chamber prior to crating
- Multi-layer packaging: heavy-duty corner EPE foam, PE protective wrap, and fumigation-free solid timber crates
- 3D container loading simulation to prevent any panel-to-panel vibration during ocean voyage
