630 Ventilation Outlet

630 Ventilation Outlet for Construction – Technical Specification

1. Core Parameters

Core Processing Method: CNC metal spinning forming combined with wiredrawing finishing, followed by secondary machining for precision. Equipment includes CNC metal spinning lathe and fully automatic wiredrawing machine.
- CNC spinning spindle speed: 1000–1500 r/min
- Roller feed rate: 8–12 mm/s
- Single pass deformation: 0.3–0.5 mm
- Wall thickness uniformity deviation: ≤ ±0.08 mm
- Wiredrawing: axial direction, 15–20 m/min, belt grit 1200#
Raw Material Preparation: 6063 aluminum alloy sheets undergo alkaline degreasing (50–60°C, NaOH 4–6%, 8–12 min), water neutralization, drying (80–100°C, 15–20 min), and flattening (flatness deviation ≤0.2 mm/m) to remove oil, oxide scale, and surface scratches.
CNC Process Control: CNC metal spinning lathe with G-code programming defines spinning paths. Real-time diameter and height data acquisition at 12 Hz for closed-loop control:
- Ø615 mm tolerance ≤ ±0.4 mm
- H373 mm tolerance ≤ ±0.3 mm
- End faces precision-turned on CNC lathe; perpendicularity error ≤ 0.1 mm

Post-Processing: Mechanical deburring at 3200 r/min with 1500# abrasive wheel. Compressed air cleaning removes residual debris, followed by dimensional recheck and surface quality inspection per core parameters.

Standards: ISO 9001:2015 quality management system, GB/T 3880.1-2012 aluminum building profiles standard. Full-process quality control from raw material intake to finished product delivery.
Raw Material Inspection:
- Spectrometer analysis: element deviation ≤ ±0.05% (Mg 0.45–0.9%, Si 0.2–0.6%)
- Hardness test: ≥60 HB
- Surface check: visual + 20× magnifier, no cracks, inclusions, dents
Process Inspection:
- Spinning Form Accuracy: curvature template, adherence ≥98%
- Dimensional Inspection: CMM (±0.005 mm) for Ø615 mm, H373 mm, 2.0 mm thickness
- Wiredrawing Inspection: visual uniformity, Ra measured with roughness tester
- Edge Inspection: no burrs, sharp edges; chamfer R ≥ 1.5 mm
Final Inspection: Sampling per GB/T 2828.1-2012, AQL 2.5. Items include dimensional verification, material recheck, surface, appearance, and assembly fit. Products are tagged with traceability codes including raw material batch, equipment, and inspector information.

Capacity: 5 CNC spinning lathes, 3 wiredrawing machines, 2 CNC lathes in production line. Daily output: 60 pcs per line (2 shifts, 8h each), max monthly output: 3600 pcs. Supports parallel multi-equipment production for large projects.
Production Lead Time:
- Small batch (10–50 pcs): 5–8 working days
- Large batch (≥100 pcs): 10–15 working days
- Urgent orders: 3–5 working days (schedule adjusted)
Delivery: Packed with pearl cotton + cardboard + wooden pallet (50 pcs/pallet). Domestic logistics 2–7 days depending on region; on-site construction delivery available with 3-day advance notice.

Core Application: Integrated into building HVAC systems for indoor and outdoor ventilation, mounted on walls, rooftops, basements, or equipment rooms, ensuring airflow and exhaust of indoor air.
Operating Conditions:
- Temperature: -40°C to 80°C (6063 aluminum alloy)
- Medium: air and non-corrosive building exhaust gases
- Building Types: commercial complexes, offices, residential, industrial, hospitals, schools
Interface Requirements: Must match Ø615 mm × H373 mm. Supports duct connection customization; client provides duct dimensions and installation details.

Fire Smoke Ventilation Systems: Acts as smoke outlet, aluminum withstands high temperature, ensures rapid smoke evacuation during fire.
Cleanroom Ventilation: Provides dust-free airflow, wiredrawing surface resists dust accumulation, easy cleaning.
Parking Garage Ventilation: Handles high airflow, humid environment; corrosion-resistant aluminum.
BIPV Integrated Ventilation: Supports building-integrated photovoltaics ventilation, combines energy efficiency with airflow.

Warranty: 24 months from acceptance; covers dimensional deviation, material defects, surface finish issues, improper installation. Free replacement or repair; shipping and on-site costs covered.
Technical Support: Pre-sale selection consultation, installation manuals, CNC diagrams, phone/video guidance, on-site installation support for large orders.
Feedback & Response: 24h response to inquiries, 1–3 working days solution. Dedicated personnel ensure closed-loop quality follow-up.
Post-Warranty Services: Paid repair, replacement, refurbishing (e.g., wiredrawing surface restoration). Optional long-term maintenance agreements with annual inspections (1–2 times/year) and maintenance advice.
