Melt Blown Pinning Die Head

Tan Vinh Phat melt blown pinning die head from vietnam factory primarily comprises two streams of high-speed, high-temperature hot air being expelled from the nozzle holes on both sides, creating a converging airflow. The polymer melt extruded through these holes undergoes a thinning process, increasing the density of the fibers. This results in improved filtration capabilities and the capacity to effectively isolate bacteria and particulate matter.

The primary function of the melt blown pinning die head is to extrude the molten material through a set of fine nozzles or holes to create ultra-fine fibers. These fibers are then blown by hot air currents and collected on a moving conveyor to form a nonwoven fabric with exceptional filtration and absorption properties. The die head design and the size and arrangement of the nozzles are essential for controlling the characteristics of the resulting melt-blown fabric, including fiber diameter and web density.

Melt-blown nonwoven fabrics are widely used in applications like air and liquid filtration, medical masks, and absorbent materials. The quality and performance of the fabric often depend on the precision and design of the melt-blown pinning die head.
