Machine Application

Mould Bent Glass Tempering Machine is a special plant used to produce the bent tempered glass with multi curvature, which mainly used in the fields of rear doors and side doors of automotives (the side door also is multi curvature), trucks, furniture, etc. Our technology supports production for premium automotive brands including BMW, Audi, Toyota, Honda, Hyundai, Peugeot, and more.

Technical Features

Loading Table

1. Equipped with LED light to detect glass defects before processing.

Heating Section

1. Sectional driving for ceramic rollers: the driving speed of the last zone is optimized for efficiency.
2. Sectional heating: individual heating zones for each working position with ceramic plates to ensure isolation.
3. Ceramic plates at the top of the oven ensure even heating and prevent debris from falling.
4. Triple belt drive system for ceramic rollers ensures simultaneous, stable running and prevents glass scratches.
5. Gapless heating element design (parallelogram shape) for superior heating uniformity and higher product quality.

Quenching Section

1. Trumpet type air nozzles for stronger air pressure and lower energy consumption.
2. Round type air ducts to minimize air loss and maximize pressure efficiency.
3. Modular quenching design for precise adjustment and rapid mould changes.

Control System

1. Core components (PLC, inverters, contactors) utilize high-end Siemens technology.
2. Profinet network data for servo motor control, significantly reducing interference compared to traditional wiring.

Frequently Asked Questions

What is the thickness range of glass this furnace can process?
The machine is capable of tempering glass with a thickness range from 3mm to 19mm, depending on the specific model and configuration.
What industries are these bent tempering furnaces primarily used for?
They are mainly used in the automotive industry for rear windscreens and side windows, as well as for specialized truck windows and architectural furniture glass.
Which brands of electronic components are used in the control system?
We use top-tier global brands including Siemens for PLCs, inverters, and contactors, and Schneider for specialized inverters to ensure stability and precision.
How does the machine ensure uniform heating for complex shapes?
The furnace uses sectional heating with individual zones and a gapless heating element design (parallelogram shape) to provide highly even thermal distribution across the glass surface.
Is it difficult to change moulds for different glass curvatures?
No, the quenching section features a modular design which makes mould changes easy and significantly reduces the time required for adjustment between different production runs.
Can the machine size be customized for my factory?
Yes, both the dimensions and power specifications can be customized based on the customer's factory layout and specific production requirements.
