Automobile production line comparison: PUR glue rolling or headliner wet method?

The two production roles

The Automobile Headliner Wet Method Line is intended for automobile interior headliners made from a PU foam sheet, non-woven fabric, and glass fiber felt. Its sequence includes PU feeding, glue rolling, spraying, conveying, coil feeding, cutting, transfer, and forming-press handling. Five layers are superposed before forming and pressure maintaining, after which a reclaiming gripper sends the finished part to manual collection or the next process.

The Glue Rolling Production Line (PUR glue) addresses a narrower operation: applying PUR glue to one side of a battery compartment lining plate before the plate enters a post-process composite reinforced-plate operation. Its line body consists mainly of a PUR glue rolling machine, a sliding table, and related mechanisms. Automatic glue feeding supports the coating step.

Process and material comparison

How the control systems differ

The PUR glue rolling line uses PID temperature control for the glue application system. Its sliding table is servo controlled for positioning and uniform movement. These controls fit a coating operation where the plate is positioned under the rolling process and then transferred to composite reinforcement.

The headliner line coordinates more stages. Its material feeding, spraying, conveying, cutting, transfer, feeding, and discharging mechanisms work around the five-layer assembly and forming press. The line also integrates a MAS management monitoring system for production tracking, material scanning error prevention, and visual management. Optional modules include reinforced glass fiber placement, sheet fabric placement, and an ultrasonic warning label system.

Which line suits which project?

Choose the Glue Rolling Production Line (PUR glue) when the project is centered on a battery compartment lining plate and the required handoff is a post-process composite reinforced plate. The relevant purchasing discussion should focus on the plate geometry, one-sided coating area, PUR glue conditions, and the required composite reinforcement step.

Choose the Automobile Headliner Wet Method Line when the project requires a multi-layer headliner flow using PU foam sheet, non-woven fabric, and glass fiber felt. Picture the material route through feeding and cutting, then check that the factory has space for conveying, spraying, five-layer superposition, forming, and finished-part removal.

The two lines can both belong to an automotive interior manufacturing plan, but they address different parts and different process boundaries. Send the supplier the target part drawing, material stack, adhesive specification, forming requirements, and planned output so the line configuration can be matched to the production cell.
