Flat & bend furnaces experience both high thermal loads and mechanical forces. Wings Logic uses:

• Heavy-duty structural steel frames
• Reinforced bending zones
• Stress-relieved fabrication

This ensures:

• Dimensional stability
• Accurate mold positioning
• Long-term mechanical reliability

Structural rigidity is essential to maintain bending accuracy over thousands of cycles.

High-Performance Thermal Insulation

The furnace chamber uses multi-layer high-temperature insulation, ensuring:

• Stable internal temperature
• Minimal heat loss
• Protection of forming mechanisms

Thermal stability directly impacts bending repeatability and glass quality.

Forced Hot Air Technology

Unlike radiation furnaces, flat & bend systems rely heavily on active convection heating to:

• Achieve uniform glass temperature
• Overcome coating reflectivity (Low-E glass)
• Control viscosity before bending

Wings Logic furnaces use:

• High-efficiency convection blowers
• Optimized ducting systems
• Precision nozzle layouts

This ensures consistent heat penetration, even for complex shapes and coated glass.

Zone-Based Temperature Control

The furnace is divided into multiple independently controlled heating zones, allowing:

• Local temperature correction
• Edge-to-center balancing
• Thickness-specific heating curves

This level of control is critical to avoid:

• Uneven bending
• Optical distortion
• Residual stress concentration

Gravity Bending System

In gravity bending mode, glass softens and gradually bends under its own weight over a precision-machined bending mold. Engineering considerations include:

• Controlled heating rate
• Mold material and surface finish
• Bending radius accuracy

This method delivers natural curvature and excellent optical quality, especially for architectural applications.

Press Bending System (Optional)

For tighter radii and higher repeatability, Wings Logic offers press bending technology, where:

• Heated glass is shaped using upper and lower molds
• Forming pressure is precisely controlled
• Geometry is fixed with high accuracy

Press bending is ideal for:

• Automotive and façade glass
• High-volume curved production
• Strict dimensional tolerances

Precision Mold Design

Bending molds are engineered using:

• CNC-machined steel or special alloys
• High-temperature resistant materials
• Optimized surface geometry

Mold accuracy directly determines:

• Final glass shape
• Optical quality
• Production consistency

Wings Logic treats mold engineering as a core R&D discipline, not an accessory.

Ceramic Roller & Support Technology

Glass transport through the heating zone uses high-precision ceramic rollers, ensuring:

• Smooth glass movement
• Stable thermal exposure
• Minimal surface marking

During bending, support systems are designed to:

• Prevent sagging outside intended curvature
• Maintain edge integrity

Advanced Quench Engineering

After bending, glass must be tempered without altering the achieved shape. Wings Logic quench systems provide:

• Independent top & bottom air control
• Uniform nozzle distribution
• Controlled cooling intensity

This ensures:

• Proper surface compression
• Safe fragmentation behavior
• Shape retention without deformation

Curved glass makes optical distortion more visible. Wings Logic flat & bend furnaces are designed to minimize:

• Roller wave
• Anisotropy
• Surface waviness
• Edge distortion

This is achieved through:

• Uniform heating
• Controlled forming speed
• Balanced quenching

The result is architectural-grade curved glass.

Recipe-Driven Bending Control

The furnace control system allows:

• Storage of bending recipes
• Control of heating curves
• Bending timing synchronization
• Quench pressure profiles

This ensures:

• Repeatability
• Faster setup
• Reduced scrap rate

Real-Time Monitoring & Correction

Sensors continuously track:

• Temperature distribution
• Glass position
• Forming sequence timing

The system automatically compensates for variations, ensuring stable output over long production runs.

Despite its complexity, Wings Logic flat & bend furnaces are optimized for energy efficiency through:

• Efficient insulation
• Optimized air circulation
• Intelligent power control

This reduces operational cost while maintaining high-precision performance.
