 | Intelligent and precise temperature control to prevent material yellowing The production line adopts a PID intelligent constant - temperature system combined with hot - oil circulation or electromagnetic heating technology. The temperature control accuracy can reach \pm 1^{\circ}C, ensuring that when processing heat - sensitive PU or high - grade genuine leather, the leather will not turn color, become brittle or lose elasticity due to local overheating, and the original texture of the material is maintained. |
 | Full hydraulic pressure equalization technology ensures consistent thickness. For wide - width leather (such as 1.8 meters wide), the equipment is equipped with a hydraulic automatic compensation roller. It can eliminate the minor deflection of the roller caused by pressure, ensuring that the leather is evenly stressed from left to right. This not only eliminates physical wrinkles but also minimizes the thickness tolerance of the whole roll of leather. |
 | Multifunctional integrated compounding to improve bonding fastness The production line integrates the full - set processes of unwinding, pre - heating, laminating, ironing, and cooling. Whether it is release paper lamination, TPU film compounding or fabric backing bonding, all can be completed in one pass. High - pressure ironing not only enhances the surface gloss but also ensures that the inter - layer peeling strength far exceeds the industry standard. |
 | Closed-loop tension digital control to prevent stretching deformation Equipped with high-precision tension sensors and variable-frequency drive control systems. Whether it is thin and light ultra-fine leather or thick cowhide, the production line can maintain a constant tension throughout the process, effectively preventing problems such as unstable dimensions or shrinkage of leather caused by excessive stretching at high temperatures. |
 | Efficient circulating water-cooled sizing, instantly locking in the texture After ironing, the leather immediately enters multiple sets of circulating water-cooled roller groups. Through rapid physical cooling, the resin softened by heat is quickly transformed into a stable state. This process can effectively prevent surface adhesion during winding and perfectly lock in the mirror-like luster or embossed texture after ironing. |
 | Intelligent after - sales interaction to achieve flexible production Equipped with a PLC centralized control system and an after - sales interaction interface. Users can set different production parameters (temperature, pressure, speed) for different materials (such as PVC, PU, semi - vegetable tanned leather). The intelligent after - sales interaction system greatly shortens the replacement and debugging time and improves the automation level of the production line. |
