When wood grain aluminum veneer manufacturers produce aluminum veneer, the market will encounter such and other problems. The uneven surface of wood grain aluminum veneer is one of the problems often encountered, so the reason for the uneven surface of wood grain aluminum veneer what is it then? There are many reasons for the unqualified aluminum veneer, such as the extrusion die setting problem of the wood-grained aluminum veneer, the problem of the support pad, etc. Let me list the specific reasons for the uneven surface of the aluminum veneer: (1) Wood-grained aluminum veneer The length ratio of the working belt of the veneer extrusion die or the wrong design of the cavity size and the flow rate ratio are seriously out of balance. (2) The wood-grain aluminum veneer extrusion die has an obstruction angle and a flow-enhancing angle. (3) The drop ratio of the upper and lower die working belts of the wood grain aluminum veneer extrusion die is out of tolerance.
(4) The working belts of the upper and lower dies of the wood-grain aluminum veneer extrusion die are not parallel and have bell mouths. (5) The resistance (division) flow table of the upper die in the extrusion die cavity of the wood grain aluminum veneer 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 wood-grain aluminum veneer extrusion die (the electric spark is not well laid) or too large (the working belt is cracked and deformed without support).
(7) New molds or repaired wood-grain aluminum veneer extrusion molds have different smoothness due to the unevenness of the rough sand polishing work belts of the mold factory. (8) There are oil stains on some aluminum veneer extrusion work belts. (9) The support pad is too small to obstruct.
(10) Waves appear about 1m from the end of the wood grain aluminum veneer (V3 volume aluminum is pressed in). Wood grain aluminum veneer,.
