Guangdong Foshan Aluminum Profile Processing Center Manufacturer Introduces the Causes and Solutions of Scratches in Aluminum Profile Processing

　　 Guangdong Foshan Aluminum Profile Processing Center Manufacturer Introduction to the causes and solutions of scratches in aluminum profile processing

　　Various problems may occur during the processing of aluminum profiles, which is not uncommon for aluminum profile manufacturers. We will analyze the causes of problems such as black and white tooth marks or uneven surfaces on the processed aluminum profiles.

　　Guangdong Foshan Aluminum Profile Processing Center Manufacturer: Aluminum Extrusion Processing

　　Cause: Human factors and the visibility of mechanical tools.

　　(1): The profiles extruded from the mold are above the double holes (multi-hole structure), because the speed of the mold holes is uneven, and the length of the profiles is uneven. The wide block black and white surface is not smooth, and the scratch surface of the air-oxidized profile is dark gray-black. It is waste in the aluminum profile processing and extrusion process.

　　(2): When the aluminum profile processing mold has been used for too long, the mold blank, support pad, and special-shaped pad, etc., at the entrance and exit are contaminated with a large amount of aluminum metal material, causing the profile to be scratched. This situation is very rare.

　　(3): Sometimes, the aluminum profiles on one side of the cold bed are not neat on the iron frame, or when checking the profiles, one of the profiles twitches and rubs against each other, causing a block-like tooth scratch contour (at room temperature). In particular, profiles with wider widths (atmospheric pipes, semi-transparent profiles, joints, etc.) or curved profiles are more likely to cause surface scratches!

　　(4): On the sawing table for cutting finished aluminum profiles, the storage rack and framed profiles are organized and crowded. Lifting and retrieving one is very easy to cause scratches between each other.

　　(5): Improper handling of aluminum chips (adhesion) during actual operation is also a key cause of scratches.

　　(6): During the entire transportation process of the aluminum profiles, the shaking and floating are too large, and the lining is not fixed well.

　　 Guangdong Foshan Aluminum Profile Processing Center Manufacturer Solutions to the above causes:

　　(1): If the speed and length of the aluminum profiles in the extrusion mold holes are uneven, adjustments should be made as much as possible by trimming. For profiles with more than 3 holes, if the length is uneven, use a graphite board (high-temperature felt) to separate them so that the multi-hole aluminum profiles will not rub against each other during processing, causing scratches.

　　(2): Before installing the mold, be sure to check: whether the mold blank, support pad hole, and special-shaped pad hole can accommodate the profile feeding size, whether there is white aluminum sticking, and if so, it should be eliminated as soon as possible. To avoid chip solder pads sticking to aluminum, apply some high-purity graphite oil when the solder pad temperature reaches 150 degrees.

　　(3) Guangdong Foshan Aluminum Profile Processing Center Manufacturer: When extruding aluminum profiles, they must be processed one by one.

　　(4): The profiles on service platforms such as the cold bed, feeding table, and saw bed should not be too full, and the profiles should be separated from each other. The downstream workers should practice as soon as possible to avoid mutual friction and impact between the aluminum profiles.

　　(5) Guangdong Foshan Aluminum Profile Processing Center Manufacturer: Aluminum chips generated during the processing, sawing, cutting, framing, and packaging of aluminum profiles need to be blown away (roots and branches) each time before the next operation.

　　(6): During transportation, they should be bundled securely to prevent the profiles from shaking. The surfaces with specified heights need to be separated and bundled with plastic deformation (foam plastic) paper branches. Start slowly, drive smoothly, and pay attention to sudden braking!
