What Are the Common Quality Problems in the Production of Aluminum Profiles? -WJW Aluminium Extrusion SUPPL
Aluminum profiles form different aluminum profile products by melting, squeezing, and various surface treatment (mainly include: oxidation, electro -swimming coating, fluorocarbon spraying, powder spraying, wood grain transfer, etc.). Then the quality of aluminum profiles is a very important problem. Let's learn about the following points: 1. Strang: Mainly aluminum stick temperature and extrusion speed. 2. Damage: Material export graphite, roller wear, belt wear, and long short and short aluminum material damage. 3. Bending: aluminum profile overheated and straight, insufficient straightened power, uneven crossing bridge. 4. Shape: Mold work with a crack bridge, no pad deformation when the aluminum profile is straightened. 5, concave shadow: improper installation of shelf, conflict, embryo installation. 6, complicated: aluminum rod, too thin pressure, unclear for a long time. 7. Bad: When the scaffold is blocked, the material and the material are friction when the frame is installed, the installation frame is too dense, and friction is caused during transportation. 8. Low hardness: Baseball temperature, exit temperature, cooling speed, installation method, improper use of aluminum profiles. 9. Reverse: Straight, aluminum profile mold design improperly. 10. Landing mouth: When cutting, the profile is not parallel to the baffle. 11. Bond: The temperature of the stick is too low, the aluminum rod quality is poor, and the mold is squeezed for a long time. 08-02
