The production line consists of a material unwinding, pre-treatment, coating, printing, drying and curing, embossing/texturing, bronzing, cooling, material winding, and environmental protection treatment system. The material unwinding and pre-treatment sections achieve automatic web guiding, preheating and dust removal; the coating section selects methods such as blade coating, roller coating, and curtain coating according to the process, completing multi-layer coating such as primer, midcoat, and topcoat; the printing section can achieve patterns and colors through gravure, color register, and transfer printing; the drying and curing process mainly utilizes hot-air ovens, and some high-end lines are equipped with UV curing units to enhance efficiency and performance; the post-processing section imparts a genuine leather texture and soft feel to the product through processes such as embossing, texturing, and ironing; the end section automatically winds and cuts the material to ensure the finished product is neat and orderly. The environmental protection system focuses on treating VOC exhaust gas, wastewater, and slurry waste residue to meet clean production requirements.

The PU finishing line is characterized by good texture, folding resistance, breathability, and excellent environmental friendliness. Water-based and solvent-free PU technology has become mainstream. The PVC finishing line is low-cost, easy to process, and has strong weather resistance, making it suitable for high-volume, cost-effective products. The entire production line has a high degree of automation, stable vehicle speed, and uniform coating, achieving various effects such as wear resistance, scratch resistance, flame retardancy, antibacterial properties, matte finish, high gloss, frosted finish, and imitation velvet. The product performance is stable and the appearance is rich.

The PU/PVC finishing production line is compatible with various substrates and formulation systems, combining versatility, economy, and functionality. It is a key equipment for the artificial leather and synthetic leather industry to achieve large-scale, standardized, and green production.
