STATE CROWN Behind the Scenes: Precision Engineering Your Custom Windows

Step Inside Our World: At STATE CROWN, a window isn’t stamped out – it’s meticulously engineered. Follow the journey of your custom creation:

Stage 1: Material Integrity – Where Excellence Begins

• Raw Aluminum: Only certified 6063-T5/T6 billets enter production (spectrometer verified).
• Core Components: PA66 GF25 thermal breaks from EU suppliers, EPDM gaskets from TPE leaders, Siegenia/G-U hardware – all batch-tested.

Stage 2: Precision Machining (CNC Dominance)

• Cutting: CNC double-miter saws achieve angles within 0.1-degree tolerance – critical for airtight corners.
• Milling/Drilling: Automated CNC centers create drainage channels, hardware pockets, and reinforcement slots with micron accuracy.

Stage 3: Thermal Break Assembly – The Crucial Bridge

• The “roll pressing” process fuses aluminum profiles with PA66 GF25 bars under controlled heat/pressure. State-of-the-art rollers ensure consistent bond strength (>30 N/mm).

Stage 4: Frame Fabrication – Building Strength

• Corner Reinforcement: Steel reinforcements inserted for large spans. Corners assembled using:
  • Precision dowel pins
  • High-strength polyurethane adhesive injection
  • Automated corner crimping
• Welding (Optional): For seamless corner aesthetics on specialty designs.

Stage 5: Glass Unit Production – The Heart of Performance

• Cutting & Edging: Automated lines with diamond wheels ensure clean, safe edges.
• Cleaning: Ultrasonic baths remove all contaminants.
• Spacer Application & Sealing: Robotic application of desiccant-filled spacers, butyl primary seal, and structural silicone secondary seal. Climate-controlled curing chambers.

Stage 6: Final Assembly & Calibration

• Glass Mounting: Setting blocks ensure even load distribution and thermal expansion space.
• Hardware Installation: Master technicians meticulously install and calibrate hardware for effortless operation (torque testing included).
• Sealing: Triple EPDM gaskets hand-fitted.

Stage 7: Relentless Quality Control (Our Non-Negotiable)

• Dimensional Checks: Laser scanners verify tolerances (±0.5mm).
• Performance Simulation:
  • Air Infiltration Test (ASTM E283): Max ≤ 0.5 cfm/ft² @ 75Pa
  • Water Resistance Test (ASTM E331): Passes > 600Pa wind-driven rain
  • Structural Load Test (ASTM E330): Survives positive/negative loads exceeding regional codes
• Functionality Audit: 100% hardware operation check (open/close/lock cycles).

Sustainability Embedded:

• Aluminum is infinitely recyclable (75%+ recycled content in our standard profiles).
• Solar-powered factory sections & closed-loop water systems.
• REACH-compliant surface treatments.

Timeline Transparency:

• Design Finalization: 3-5 days
• Manufacturing: 10-15 working days
• Global Shipping: DDP logistics managed
