The Needle Punching Plate Share

The needle punching plate is used for puncturing on the surface of a felt. The plate is generally a metal plate, and a plurality of metal needles are vertically embedded on one side, and the installation device is mounted on the other side. The surface of the felt has low strength and will form a gas-impermeable surface strengthening layer after being processed, which will damage the breathability of the material. The use of the needle punching plate with many metal needles to press out countless small holes when the felt surface reinforcement layer has not fully cured, and the air permeability of the felt can be improved without lowering the surface strength of the material.

Characteristics of the needle punching plate: The diameter of the metal needle is 0.5mm-3mm. The metal needle is embedded in the needle punching metal plate with the tip facing outward and the length is 50mm-150mm. In order to prevent the metal needle from deforming and moving on the pressing plate. The joint of the metal needle and the needle punching plate is designed with a semi-circular convex reinforcement, and the metal needle density is 40-50 pieces per square decimeter.

After the needle punching plate is installed in the calender, the felt is subjected to needling treatment, which is a necessary process for the needle felt processing, and the strength and depth of the pressing can be adjusted according to the processing requirements of the felt.
