        The flower plate holes of the bag filter are punched using molds

        DATE:2021-09-25
          The flower plate holes of the bag filter are punched using molds, and the large flower plates of the bag filter are made using CNC equipment.

        The flower plate holes of bag dust collectors are punched using molds. Large bag dust collector flower plates are made using CNC equipment, but some manufacturers use manual cutting to make the holes. The edges of the holes are not rounded like those punched out by equipment, and there are no marks in the circle. The roundness is also the main reason why the dust bag expansion ring cannot be opened or opened excessively, or the circle is irregular and opens into an elliptical shape when the expansion ring is opened, which is the main reason for bag dropping.
