Automotive Glass Tempering Furnace

Automotive Glass Tempering Furnace is a heating, bending and air-quenching system designed for the production of curved tempered automotive safety glass. It combines controlled thermal processing, programmable forming and high-pressure quenching for processing automotive glass to specified curvature, strength and fragmentation requirements according to the glass specification, tooling and process parameters.

Controlled Heating Before Forming: Automotive glass requires a controlled and sufficiently uniform thermal profile before bending and quenching. The furnace uses zoned heating control to adjust heat distribution according to glass specification and forming requirements.

Zoned Temperature Control: Independent heating zones allow the thermal profile to be adjusted for different glass sizes, thicknesses and geometries. This supports consistent thermal conditions before forming and quenching.

Micro-Zone Convection Heating: Micro-zone convection improves heat transfer to the glass surface and helps compensate for differences in heat absorption across different areas of the glass, particularly for curved geometries.

Coated Glass Compatibility: The furnace can be configured for supported coated glass according to the coating type, glass thickness and required thermal processing conditions.

Low-E & Solar-Control Glass: For supported Low-E or solar-control glass, heating parameters and process settings are configured according to the coating characteristics and glass specification.

Process Parameter Adjustment: Heating, forming and quenching conditions can be adjusted according to the glass composition, thickness, coating and required product geometry.

Programmable Bending for Automotive Glass: The bending section forms heated glass according to the programmed product profile before quenching. The adjustable forming mechanism accommodates different curvature requirements and glass geometries within the configured machine range.

Adjustable Forming Mechanism: The forming mechanism is adjusted according to the required curvature, forming depth and glass geometry, allowing different automotive glass profiles to be processed on the same furnace.

Controlled Forming Movement: Controlled mechanical movement maintains the forming position and movement sequence between production cycles, supporting consistent curvature for the same glass model.

Large-Format Curved Glass: The forming configuration can accommodate larger curved components, including panoramic roof glass, based on the required glass geometry and machine configuration.

Controlled Air Quenching After Forming:  After forming, high-pressure air is applied to both glass surfaces for rapid cooling and thermal stress formation required for tempering.

Adjustable Quenching Conditions: Quenching conditions can be adjusted according to glass thickness, geometry and the required tempering process.

Upper & Lower Air Control: Independent control of the upper and lower airflow allows the cooling conditions on both glass surfaces to be adjusted during the quenching cycle.

Inverter-Driven Blower System: Inverter-driven blowers allow quenching airflow to be adjusted through the control system according to the selected process parameters.

Recipe-Based Production Control: The control system stores process parameters for individual glass models, allowing operators to select the required recipe during production and model changeover.

Recipe Management
Recipes can include settings for:

• Heating
• Conveyor movement
• Bending
• Quenching
• Cooling

HMI Monitoring: The HMI displays machine status, process parameters, temperature conditions, alarms and equipment states during operation.

Alarm & Safety Interlocks: The control system monitors equipment alarms and safety interlocks to stop or restrict operation when defined safety conditions are not met.

Siemens PLC Control: The furnace uses a Siemens PLC, with Schneider Electric electrical components and industrial drive components selected for the control system.

Controlled Heating Profile: Zoned heating and micro-zone convection are used to maintain controlled thermal conditions across the glass surface before forming and quenching.

Balanced Quenching: Upper and lower air-quenching conditions can be adjusted to maintain balanced cooling across the glass surfaces and support consistent tempering.

Forming Consistency: Programmable forming movement and controlled forming parameters support repeatable curvature for the same glass model.

Optical Quality Considerations: Heating uniformity, roller movement, forming accuracy and quenching balance are controlled to help reduce process-related optical defects such as roller wave and uneven optical appearance. Final optical quality depends on glass specification, tooling and process parameters.

Technical Support After Installation: Technical support covers remote troubleshooting, spare-parts supply and on-site service.

Remote Technical Support: Technical assistance is available through video communication and remote diagnostics, with an initial response target of 30 minutes.

Spare Parts: Standard replacement parts can be prepared for dispatch within 24–48 hours, subject to stock availability.

Regional Service: Service branches in Egypt and Qatar provide regional technical support and spare-parts coordination.

On-Site Service: Engineers provide installation support, troubleshooting, equipment adjustment and production verification at the customer's facility.
