Flat And Bend Convection Furnace

Integrated Tempering & Bending Technology Driven by Advanced Thermal and Mechanical Engineering

The Flat & Bend Convection Furnace represents the highest level of sophistication in glass tempering technology. It is not merely a furnace — it is a precision thermo-mechanical system that combines controlled convection heating, gravity or press bending, and exact stress management into a single, unified production process.

At Wings Logic, flat & bend convection furnaces are engineered through extensive thermal research, forming simulations, and real-world architectural project feedback. These systems are designed to meet the increasing demand for curved, complex, and architecturally expressive glass, without compromising safety, optical quality, or long-term reliability.

Why Flat & Bend Technology Defines Advanced Glass Factories

Modern architecture increasingly demands:

Traditional flat furnaces cannot meet these requirements. Flat & bend furnaces solve this by integrating heating and forming into one synchronized process, ensuring that bending occurs at the optimal glass viscosity window. This integration is what separates true furnace engineering from mechanical improvisation.

Core Engineering Philosophy at Wings Logic

Wings Logic flat & bend convection furnaces are built on five fundamental engineering principles:

Uniform Heating Before Any Forming Action
Controlled Glass Softening Across Entire Thickness
Stable and Predictable Bending Geometry
Stress Profile Preservation After Forming
Repeatability Independent of Operator Skill

Every subsystem — thermal, mechanical, pneumatic, and software — is designed to work as one controlled physical process.

Furnace Chamber & Structural Integrity

Reinforced Furnace Frame Design

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.

Advanced Convection Heating System

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

Bending Technology – Where Engineering Becomes Art

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

Mold Engineering & Materials Science

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.

Glass Transport & Support System

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

Quenching System – Stress Control After Bending

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

Optical Quality & Distortion Management

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.

Intelligent Control Software & R&D Logic

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.

Energy Efficiency & Process Optimization

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.

Performance Under Industrial Conditions
