Automotive Glass Production Line
Why Choose SANKEN for Your Automotive Glass Production Line?
SANKEN provides automotive glass production line solutions for windshields, side windows and rear windows. Equipment options include automatic glass pre-processing, windshield bending, curved glass washing, vacuum pre-lamination and bending tempering, with configurations planned around your glass products, production capacity and factory layout.
Equipment for Different Automotive Glass Products
Select equipment for laminated windshield production or bent tempered side and rear window glass. The equipment combination depends on the glass product and its processing requirements.
Automatic Pre-processing and Process Control
Automatic loading, CNC cutting, breaking, edging and drilling can be combined in a pre-processing line. PLC, touch-screen and servo controls support the functions of individual machines, according to the selected configuration.
Production-Line Planning and Project Support
SANKEN supports equipment configuration and factory layout planning, followed by installation, commissioning, operator training and after-sales technical support.
Automotive Glass Production Process
The equipment below serves different production routes. Windshield bending and vacuum pre-lamination belong to the laminated windshield route, while bending tempering is used for the tempered side and rear window products described here. These are main process stages; the final sequence and any additional equipment are defined for each project.
Laminated Windshield Glass
Glass pre-processing → Windshield bending → Curved glass washing and drying → Glass and interlayer assembly → Vacuum pre-lamination → Autoclave processing
Vacuum pre-lamination prepares the assembled glass for subsequent autoclave processing. Autoclave capacity and compatibility with the windshield process should be confirmed as part of the equipment configuration.
Bent Tempered Side and Rear Window Glass
Glass pre-processing → Washing and drying → Bending and tempering → Finished glass inspection
Drilling and other product-specific operations are included where required by the glass design. The production route should be confirmed against the intended finished product.
Automatic Automotive Glass Pre-processing Line
The shuttle-type pre-processing line combines an automatic loading table, positioning table, CNC cutting and automatic breaking machine, CNC edging machine, automatic drilling machine, conveying tables and a shuttle transfer system.
- Servo-controlled cutting, breaking, edging, drilling and shuttle movements.
- Automatic transfer between the configured processing stations.
- Connection to a glass washing machine or other downstream equipment, according to the line arrangement.

Automotive Windshield Glass Bending Furnace
The windshield bending furnace uses PLC and computer control, with an operating display for process monitoring and fault records for troubleshooting. Mould positioning on each trolley helps maintain alignment during transfer.
- Controlled heating and a continuous cooling and annealing section.
- Variable-frequency blowers for cooling airflow adjustment.
- Fault alarms, fault recording and multiple limit protections.
- A circulating trolley conveying system with upper-level entry and lower-level exit.
The original equipment configuration uses 24 trolleys. Confirm the trolley arrangement and furnace configuration for the intended windshield size and production capacity.

Automotive Curved Glass Washing Machine
The curved glass washing machine is designed for automotive windshields, side windows, rear windows and roof glass. It combines pre-spraying, heated high-pressure washing, pure-water rinsing and air-knife drying, with PLC and touch-screen control.
- Stainless steel covers and water tank.
- Variable-frequency blower control, adjusted according to glass detection.
- Glass detection to switch pure-water spraying on and off.
- Automatic pump shutdown after an extended period without incoming glass.
- Water and air filter blockage alarms, plus motor fault detection and shutdown.
- Automatic water refilling and water heating control.

Automotive Vacuum Pre-lamination Line
The vacuum pre-lamination line includes conveying equipment for the clean assembly room, a vacuum pre-lamination furnace, an unloading conveyor and a vacuum-ring return conveyor. PLC and touch-screen controls manage line operation.
This is a preparation stage before autoclave processing in laminated windshield production. The assembly area, vacuum system and downstream autoclave requirements should be considered together during line planning.

Automotive Glass Bending and Tempering Furnace
The bending and tempering equipment described here is intended for automotive side window and rear window glass. Its controls include variable-frequency blower control, temperature control and servo-controlled movements in the bending section.
Side Window Glass
Upper and lower conveying rollers use synchronized forming movements, with computer adjustment of the bending curve.
Rear Window Glass
Heated glass is formed using a shaping mould and an upper pressing die with a lifting mechanism. Transmission and lifting movements in the forming section use servo control.
The forming arrangement is selected according to the product geometry and process requirements.
