Flat Convection Furnace

Advanced Tempering Technology Engineered Through Thermal Science & Industrial R&D

The Flat Convection Furnace is the most widely used and technically refined glass tempering solution in modern glass processing plants. At Wings Logic, our flat convection furnaces are not designed as standard machines — they are the result of deep thermal research, airflow simulation, material science, and real-world production feedback.

Every furnace we engineer is built to solve the most critical challenges in glass tempering:

Uniform heat transfer
Stable stress distribution
Low optical distortion
Consistent performance across Low-E and coated glass
Long-term operational reliability

This is where engineering discipline meets production reality.

Understanding Flat Convection Tempering Technology

Glass tempering is fundamentally a controlled thermal transformation process. The objective is to heat glass uniformly to its softening point and then cool it rapidly to induce surface compression and internal tension, giving tempered glass its characteristic strength and safety properties. In convection furnaces, forced hot air circulation is used to actively transfer heat into the glass surface, rather than relying only on radiant heat. This method offers decisive advantages:

Wings Logic flat convection furnaces are engineered to control this thermal behavior at a microscopic level.

Core Engineering Philosophy at Wings Logic

Our furnace development is driven by four non-negotiable engineering principles:

Every mechanical, thermal, and software component is designed to support these principles under continuous industrial operation.

Furnace Chamber & Structural Design

Heavy-Duty Furnace Body Construction

The furnace chamber is constructed using high-grade structural steel, reinforced to maintain geometry under long-term thermal cycling. Key structural considerations include:

Resistance to thermal expansion
Mechanical rigidity at high temperatures
Long service life under continuous operation

The internal chamber geometry is optimized to support stable airflow patterns and uniform heat exposure.

Advanced Thermal Insulation System

Wings Logic furnaces use multi-layer high-temperature insulation materials, minimizing heat loss and improving energy efficiency. This insulation system:

Maintains stable internal temperature
Reduces power consumption
Protects structural components
Improves long-term furnace reliability

Thermal stability is the foundation of consistent glass quality.

Convection Heating System – The Heart of the Furnace

Forced Hot Air Circulation Technology

The defining feature of a flat convection furnace is its active air circulation system. Wings Logic furnaces use:

High-efficiency convection blowers
Precision-engineered air ducts
Optimized nozzle arrays

Hot air is delivered uniformly to the glass surface from both top and bottom, ensuring balanced heat transfer.

Air Nozzle & Flow Dynamics Design

Air nozzle design is a critical area of Wings Logic R&D. Our engineering team focuses on:

Nozzle spacing and density
Air velocity control
Turbulence optimization
Uniform heat penetration

This ensures:

No cold spots
No overheating zones
Consistent heating across glass width and length

These parameters are refined through thermal modeling and factory testing, not assumptions.

Heating Elements & Temperature Control

High-Precision Heating Zones

The furnace is divided into multiple independent heating zones, each controlled separately. This allows:

Fine temperature adjustment across the glass
Compensation for edge and center heat differences
Optimized heating curves for different glass thicknesses

Each zone operates under closed-loop PID control, ensuring real-time correction of temperature deviations.

Adaptive Heating Logic for Low-E Glass

Low-E and coated glass reflect radiant heat, making traditional furnaces inefficient. Convection heating solves this problem by:

Actively forcing heat into the glass surface
Reducing dependence on radiation absorption
Ensuring uniform heating despite coatings

Wings Logic furnaces are engineered specifically to handle soft coat and hard coat Low-E glass with stable results.

Ceramic Rollers & Glass Transport System

High-Quality Roller Design

Glass is transported through the furnace on high-temperature ceramic rollers, engineered for:

Minimal thermal deformation
Smooth rotation
Long operational life

Roller straightness and alignment are critical to prevent:

Roller wave distortion
Optical defects
Edge stress variation

Wings Logic places extreme emphasis on roller precision and bearing quality.

Speed Synchronization & Stability

Roller speed is synchronized precisely with:

Heating time requirements
Glass thickness
Furnace load conditions

This ensures stable glass movement and uniform exposure to heat.

Quenching System – Stress Engineering Zone

Controlled Rapid Cooling

After heating, glass enters the quench section, where high-pressure air jets rapidly cool the surfaces. This induces:

Surface compression
Internal tensile stress
Strength enhancement

The challenge is not cooling fast — it is cooling evenly.

Advanced Quench Air Distribution

Wings Logic quench systems feature:

Top and bottom independent pressure control
Uniform nozzle layout
Adjustable air flow intensity

This allows precise control over:

Stress profile
Fragmentation pattern
Optical quality

The result is strong, safe, and visually clean tempered glass.

Optical Quality & Distortion Control

Optical distortion is one of the biggest concerns in tempered glass, especially for façade and architectural applications.

Wings Logic flat convection furnaces are designed to minimize:

Roller wave
Anisotropy
Edge distortion
Visual haze

This is achieved through:

Uniform heating
Stable glass transport
Balanced quench pressure
Optimized air flow geometry

The outcome is architectural-grade optical quality.

Intelligent Control Software & R&D Logic

Recipe-Based Production Control

Each glass type can be processed using stored thermal recipes, defining:

Heating temperature
Zone balance
Conveyor speed
Quench pressure profile

This ensures:

Repeatable results
Faster setup
Reduced operator dependency

Real-Time Monitoring & Feedback

Sensors continuously monitor:

Furnace temperature
Air pressure
Glass movement
System status

The control system adjusts parameters dynamically, maintaining process stability even during long production runs.

Energy Efficiency & Sustainability

Wings Logic furnaces are engineered to optimize energy usage through:

Lower energy consumption directly translates into:

Performance Under Industrial Conditions

Our flat convection furnaces are designed for:

Every component is selected for industrial reliability, not laboratory conditions.

Service, Support & Long-Term Partnership

Technology alone does not ensure success. Wings Logic backs every furnace with:

Our service teams are trained not just to repair, but to optimize tempering performance.

Built for Today’s and Tomorrow’s Glass Industry

As glass applications demand:

Flat convection furnaces must evolve continuously. Wings Logic invests in ongoing research, field feedback, and thermal innovation, ensuring our furnaces remain future-ready.

Why Customers Trust Wings Logic Flat Convection Furnaces
