What is the Cause of the Uneven Surface of the Metal Mesh?
As a Perforated Metal Sheets Factory, I would like to share with you the reasons for the uneven surface of the metal mesh.
The application of metal mesh is more and more widespread, and the uneven surface of the metal mesh is one of the problems that everyone often encounters. So what is the cause of the uneven surface of the metal mesh? In fact, there are many reasons, such as: metal mesh Extrusion mold setting problems, support pad problems, etc., the blue sky seven-color metal mesh manufacturer will tell you the specific reasons for the uneven surface of the metal mesh:
(1) The length ratio of the working belt of the metal mesh extrusion die or the design of the cavity size are wrong and the flow rate ratio is seriously out of adjustment.
(2) The work of the metal mesh extrusion die has obstruction angles and flow promotion angles.
(3) The gap between the upper and lower dies of the metal mesh extrusion die is relatively poor.
(4) The working belts of the upper and lower die of the metal mesh extrusion die are not parallel, and there is a horn.
(5) The upper die resistance (division) flow table in the metal mesh extrusion die cavity is too high to block the discharge of the working belt or the drainage groove (size, depth, position) is wrong.
(6) There are too few or no empty knives on the outside of the working belt of the metal mesh extrusion die (the electric spark is not hit) or too large (the working belt is cracked and deformed without support).
(7) The smoothness of the mold work belt caused by the unevenness of the mold factory’s coarse sand polishing work belt caused by the new mold or the repaired metal mesh extrusion mold.
(8) There are oil stains on part of the metal mesh extrusion working belt.
(9) The support pad is too small and obstructive.
(10) Waves appear about 1m from the tail end of the metal mesh (V3 volume aluminum is pressed in).
