Automobile Headliner Wet Method Line (Fiberglass Rolling Adhesive Process): Specifications, Ordering and Support FAQ

The Automobile Headliner Wet Method Line (Fiberglass Rolling Adhesive Process) is a fully automated production solution for vehicle interior headliners. Buyers, procurement teams, and factory engineers regularly ask about its process principles, compatible materials, staffing requirements, and available configurations. The answers below are drawn from confirmed product documentation published by Chongqing Guang Jingxin Technology Co., Ltd.

1. What is the fiberglass rolling adhesive process, and how does it differ from a standard wet method line?

The fiberglass rolling adhesive process applies PU adhesive by rolling it onto glass fiber felt rather than relying solely on spray application. In this variant, glass fiber felt is fed through a dedicated glass fiber glue rolling machine, which coats the material evenly before it enters the multi-layer superposition stage. A complementary spraying machine then applies PU adhesive to the PU plate. The five-layer stack—PU lower non-woven fabric, glass fiber felt (glue-rolled), PU plate (sprayed), glass fiber felt (glue-rolled), and PU upper non-woven fabric—is conveyed to a forming press for pressure maintaining and final shaping. This dual-application approach (rolling + spraying) is the defining characteristic that distinguishes this line from a PU-glue-rolling-only configuration.

2. What materials are compatible with this production line?

The line is engineered specifically for the following raw materials:

• PU foam sheet (PU plate) — the structural core of the headliner
• Glass fiber felt — applied via the rolling adhesive process on both the upper and lower sides
• Non-woven fabric — used as the upper and lower surface layers

These five layers (non-woven fabric + glass fiber felt + PU plate + glass fiber felt + non-woven fabric) are superimposed and conveyed together to the forming machine. The line includes an automatic coil material feeding machine and a cutting machine to handle roll-form non-woven fabrics and glass fiber felts.

3. What are the main machine components that make up the production line?

According to the confirmed product description, the production line is composed of the following primary units:

Optional modules—such as a reinforced glass fiber placement mechanism, sheet fabric placement mechanism, and ultrasonic warning label system—can be added to extend functionality.

4. What production cycle time and labor requirements should I expect?

Cycle time: The line achieves a production rhythm of up to 62 seconds per piece, enabling high-volume, large-scale manufacturing output.

Labor: The fully automated workflow requires only 1–2 operators per shift. This compares favorably with traditional manual production, which typically requires 5–7 workers for the same output. The reduction represents a saving of approximately 4–5 workers per shift.

Material efficiency: The precision cutting system minimizes clamping distance, which reduces raw material waste and lowers per-unit material costs compared to manual cutting.

5. How does the MAS management monitoring system support production?

The production line integrates a MAS (Management Monitoring System) that provides the following capabilities:

• Real-time production monitoring — operators and managers can track every stage of the workflow, from material feeding through to discharge
• Material scanning error prevention — the system scans components before assembly to prevent incorrect materials from entering the process
• Visual management — digital dashboards display live process status, helping teams identify bottlenecks and alarms immediately
• Ultrasonic warning label system — an optional integrated module that triggers safety and quality alerts at defined control points

The MAS system is designed to connect with existing automotive factory management ecosystems, supporting data integration across the production environment.

6. What optional functional modules can be added to the line?

This production line has three optional modules:

1. Glass fiber reinforcement placement mechanism — adds a dedicated station to position additional glass fiber reinforcement, improving the structural strength of the finished headliner
2. Sheet fabric (non-woven) positioning system — ensures precise material alignment for every cycle, maintaining dimensional consistency across high-volume runs
3. Ultrasonic warning label system — improves safety and quality control by issuing automated warnings at critical process stages

These modules are described as configurable additions; contact Chongqing Guang Jingxin Technology Co., Ltd. directly to confirm availability and configuration for your specific production requirements.

7. What product performance does the headliner achieve from this process?

The fiberglass rolling adhesive process delivers the following product characteristics:

• Strong adhesion and structural integrity — the combination of rolling glue application on glass fiber felt and PU plate spraying ensures even adhesive distribution and robust inter-layer bonding
• Durability — the multi-layer composite construction contributes to long-term service life in automotive interior conditions
• Sound insulation performance — the layered structure of non-woven fabrics and glass fiber felt enhances the headliner's acoustic damping properties
• Dimensional consistency — automated material handling and a non-woven fabric positioning system maintain alignment across every produced piece
