Stage 01 Precision CNC Cutting
Extruded aluminum profiles are cut on automated dual-head CNC saws. Laser measurement tools ensure length and miter angle tolerances within ±0.5mm, creating seamless 45-degree frame corners.
Manufacturing Integrity
Engineering Excellence from Raw Profiles to Final Assembly
At Foshan Aluvoy Entry Door Systems Co., Ltd., we maintain total control over every step of production in our own facility. By adhering strictly to AS2047, NFRC, and Florida Product Approval manufacturing standards, we deliver structural durability, airtight sealing, and smooth operation on every project.
Stage 01 
Stage 02 CNC Milling & Slotting
High-speed CNC machining centers mill lock body pockets, hinge slots, hardware mounting points, and weeping channels. Every cut follows detailed CAD/BIM shop drawings for accurate site fitting.
Stage 03 Hydraulic Punching
Dedicated hydraulic punching equipment prepares clean, burr-free drainage ports, corner key locks, and multi-point lock latch cutouts without distorting structural profile walls.
Stage 04 Corner Crimping & Assembly
Corner keys are inserted into the extruded chambers and jointed using German corner crimping technology. Continuous EPDM weather seals and multi-point locking hardware are systematically fitted.
Stage 05 Structural Corner Injection & Gluing
Dual-component structural sealant is injected into every corner joint. This creates a permanent waterproof barrier and increases frame shear strength under severe wind loads.
Stage 06 Multi-Layer Export Packing
Every frame unit undergoes 5-layer protective wrapping: protective film, foam edge guards, shrink wrap, and solid wooden crates or steel transport racks to ensure safe container transport.
Quality Assurance
Standardized In-Line Quality Control (QC) Protocols
Our quality management system verifies every unit before it leaves the workshop line, reducing field issues and protecting project timelines.
1. Raw Profile & Coating Inspection
Spectrometer and thickness checks verify aluminum alloy grade (6063-T5/T6) and powder coat layer thickness (≥60 microns) before cutting begins.
2. Dimensional & Diagonal Squareness Audit
Frame and sash dimensions are measured against approved shop drawings. Diagonal tolerance is kept within 1.5mm to prevent operational binding.
3. Water Tightness & Air Infiltration Testing
Randomly selected production units undergo mock-up testing for water penetration resistance and structural air leakage per AS4420 and ASTM standards.
4. Hardware Cycling & Smoothness Check
Operators perform manual cycle tests on friction hinges, multi-point locks, and roller assemblies to confirm whisper-quiet operation and smooth latching.
