Automotive Glass Vacuum Pre-Lamination Line
SANKEN SKAL-VP series connects clean-room assembly conveying, vacuum pre-lamination, glass unloading and vacuum ring return for automotive laminated glass production. PLC and touch-screen control coordinate the line before the assembled glass proceeds to final autoclave processing.
The production arrangement uses four equipment groups: CA assembly conveyor, VP vacuum pre-lamination furnace, CU unloading conveyor and R vacuum ring return conveyor. SKAL-1319 and SKAL-1324 configurations are available for project selection.
Main Line Components
Clean-Room Assembly Conveyor: CA
SKAL-1319CA and SKAL-1324CA provide the conveying arrangement for the clean assembly area. The workstation sequence supports glass loading, checking, interlayer assembly and vacuum ring fitting before pre-lamination.
Vacuum Pre-Lamination Furnace: VP
SKAL-1319VP and SKAL-1324VP perform the vacuum pre-lamination stage on the assembled glass. The furnace is coordinated with the assembly and unloading conveyors for transfer through the process.
Glass Unloading Conveyor: CU
SKAL-1319CU and SKAL-1324CU convey glass out of the pre-lamination section and support the downstream handling arrangement.
Vacuum Ring Return Conveyor: R
SKAL-1319R and SKAL-1324R return the vacuum rings within the production area for reuse. Plan the return route around the assembly station and glass unloading arrangement.
Control and Process Integration
PLC and Touch-Screen Control
Centralized PLC and touch-screen control provide access to line operation and process settings. Coordinate the assembly conveying, furnace, unloading and ring return sections for the selected production arrangement.
Assembly Room Connection
The conveying system connects the clean assembly area with the vacuum pre-lamination furnace. Arrange glass checking, interlayer preparation and ring fitting around the required laminate structure.
Separate Conveying and Processing Specifications
Assembly and unloading conveyors have transport speeds expressed in m/min. Furnace output is expressed in pieces/hour. Match these specifications through the complete workstation and processing sequence.
Autoclave Preparation
Vacuum pre-lamination prepares the assembled glass for the subsequent autoclave stage. Coordinate the downstream transfer, batch loading and autoclave capacity with the required line output.

Paired glass thickness describes the two glass sheets, from 2+2 mm to 4+4 mm. Furnace output is expressed as pre-laminated pieces per hour; conveyor speed is expressed as transport movement in m/min.
The 235 kW figure applies to SKAL-1319VP. Assembly conveying, unloading and ring return have separate component power ratings. Confirm the complete equipment scope and electrical demand for the production arrangement.
The 22 m dimension is the ring conveyor route length. It is separate from the occupied-space dimensions of the glass conveying and furnace sections. Furnace weight is confirmed for the selected configuration.
SKAL-1324 Configuration
The corresponding equipment groups are SKAL-1324CA assembly conveying, SKAL-1324VP vacuum pre-lamination, SKAL-1324CU unloading conveying and SKAL-1324R vacuum ring return.
Send the required glass dimensions, paired-sheet thicknesses, windshield geometry, production target and workshop drawing so we can confirm the operating range, equipment dimensions and utility requirements of the selected SKAL-1324 arrangement.
Automotive Glass Pre-Lamination Workflow
Clean-Room Glass Checking & Assembly → Vacuum Ring Fitting → Vacuum Pre-Lamination → Glass Unloading → Transfer for Autoclave Processing
Prepare and Assemble the Glass
Prepare the glass pair and interlayer according to the intended windshield build-up. Check and assemble the glass in the clean-room workstation arrangement.
Fit the Vacuum Ring
Fit the appropriate vacuum ring for the glass design and move the assembly toward the furnace through the conveying section.
Perform Vacuum Pre-Lamination
The assembled glass passes through the vacuum pre-lamination furnace under the selected processing conditions.
Transfer Glass and Return Rings
Coordinate unloading and vacuum ring handling with the downstream transfer route. The ring conveyor returns rings to the designated preparation area for reuse.
Continue Autoclave Processing
Transfer the prepared laminate to a separate autoclave for final bonding according to the selected glass-and-interlayer process.
Factory Layout and Equipment Selection
Plan the clean assembly room, furnace, unloading conveyor and ring return route together. Keep the glass flow connected while allowing access for checking, assembly, ring fitting and maintenance.
For the SKAL-1319 arrangement, assembly conveying occupies 9500 × 800 × 900 mm, the VP furnace occupies 16000 × 3900 × 2950 mm, and unloading conveying occupies 8150 × 800 × 900 mm. The ring conveyor route length is 22 m.
These figures describe separate components and do not define the overall factory footprint. Arrange their positions, assembly room boundaries, operator work areas and autoclave transfer route for the actual workshop.
Select the line around glass size, curvature, paired thickness, interlayer requirements, ring design and target output. Confirm the connections and utility requirements of the final equipment combination.
