Basic Information:
  • Huawei Industrial Co., Ltd. has many years of production experience. Here are some suggestions for preventing blackening or drossing of 4 x 8 aluminum sheet during production.

    Control from the production process:
    1. When cutting the rod, use clean air to blow off the dust on the rod to reduce the dust brought in by the aluminum rod. , reduce the source of drag black and slag inclusion;
    2. The thickness of the pressure should be left enough. Too thin pressure will involve the dead area of ​​the aluminum rod into the end of the profile, resulting in blackening and slag inclusion;

    3. The extrusion speed should be effectively controlled, especially the end should be slowed down to prevent turbulent flow from being involved in skin impurities;
    4. The cylinder should be cleaned every time during production;
    Adjustment from Aluminum Sheet equipment and devices:
    1. If the extrusion rod is not tight, the movement of the extrusion rod will wear and tear the material, which will cause defects such as bile, belly, deformation, etc.;
    2. The center of the mold base should be centered up, down, left and right. It is strictly forbidden to move the mold base for production. If the upper and lower parts are wrong, contact the parts for repair;
    3. Regularly check the size of the test block and replace it with a new one. For the squeezed cake at the edge, it will also cause blackening, slag inclusion, and scrapping;
    4. The decorative aluminum plate is expected to be used for a long time. If it is seriously deformed, it will also cause a batch of scrapping. There are many scraps in production. It should be noted that the new material gallbladder must remove the dirt in the gallbladder, and can only be installed on the machine after polishing.
    Adjustment from mold design, production plan
    1. For the flat die, install a deflector to guide the flow if necessary, which can reduce the feeding port and clamp the dead zone;
    2. The gallbladder mold must be fully enclosed diversion hole, and each mold should be equipped with a comparison monitor. If the diversion hole is too large, it cannot be produced on the machine, and it must be transferred to a large machine for production;
    3. Under the production plan, according to the plan under the mold of the original mold opening machine (which can be used in common with the diameter of the path), the production of the mold sticking machine does not occur.
