Slot-die Extrusion Coating Unit

Precise control of the adhesive supply system is the core guarantee of coating uniformity. This Slot-die Extrusion Coating Unit adopts a closed-loop quantitative adhesive supply design, which not only effectively isolates external impurities and prevents adhesive oxidation and deterioration, but also achieves excellent adhesive supply stability. Within a coating width of 1000mm, the coating uniformity can be precisely controlled to ±1.5 micrometers, significantly reducing coating thickness fluctuations and ensuring consistent quality across every inch of the coated surface, laying a solid foundation for the smooth progress of subsequent processes.

To meet the precise adjustment needs of complex coating processes, the slot die extrusion coating unit is equipped with a high-precision fine-tuning mechanism, with a fine-tuning accuracy of up to 0.001mm. This ultra-fine adjustment capability allows operators to perform precise parameter calibration based on different adhesive characteristics, substrate types, and product thickness requirements, flexibly adapting to diverse production needs and significantly improving the equipment's process compatibility and product adaptability.

The stable operation and rapid repositioning of the die head are crucial for improving production efficiency. The Slot-die Extrusion Coating Unit die head rapid advance and retraction mechanism has a repositioning accuracy of ≤0.005mm. In case of model changes, maintenance, or unexpected situations, the die head can quickly complete the advance and retraction movements and accurately reposition, effectively reducing downtime for adjustments and avoiding substrate waste and quality defects caused by repositioning deviations, ensuring the continuity and stability of mass production.
