The automotive headliner wet process production line represents a sophisticated manufacturing solution that combines precision coating, catalyst application, and thermal molding technologies to produce high-quality interior ceiling components. This advanced system offers two distinct processing methods to accommodate different material requirements and production specifications in modern vehicle manufacturing.
At the heart of the PU roller-coating wet process lies a meticulously engineered sequence of operations. The production begins with polyurethane sheets undergoing precise double-sided adhesive application through specialized roller-coating machinery. Following this critical coating stage, the treated material progresses to an automated catalyst spray system that ensures proper chemical activation. The process then integrates layered fiberglass and non-woven fabric substrates before the composite assembly enters the thermal forming press. This carefully orchestrated workflow guarantees uniform material distribution and optimal bonding characteristics in the final product.
The alternative fiberglass roller-coating wet process employs a modified approach that maintains the same commitment to precision and quality. In this configuration, both upper and lower fiberglass layers receive controlled adhesive application while the central PU component undergoes catalyst treatment. The system's intelligent design ensures perfect alignment and consistent pressure during the final molding phase, resulting in headliner components with exceptional dimensional stability and acoustic properties.
Both production methodologies incorporate state-of-the-art temperature control systems and precision timing mechanisms to maintain strict process parameters. The equipment's modular design allows for quick adjustments between different product specifications, while integrated quality monitoring systems verify each production stage. Advanced material handling systems ensure gentle yet precise transportation of sensitive components throughout the entire manufacturing sequence.
