Aluminum alloy has the characteristics of low density, low melting point, good processing performance, electrical conductivity and excellent corrosion resistance. Nowadays, the shells of many electronic products are mostly 1590XX 1790NS Cast Aluminum Enclosure products, which also makes 1590XX 1790NS Cast Aluminum Enclosure products become energy saving products. Environmentally friendly products. But familiar friends all know that aluminum alloy has low hardness, and it is easy to be scratched and scratched if you are careless in the processing process. What are the reasons for the scratches? How to fix 1590XX 1790NS Cast Aluminum Enclosure products?

1590XX 1790NS Cast Aluminum Enclosure products

1. Due to the improper design of the stamping die: the crush caused by the die itself; the die is too tight, and the parts need to be pried, and the gap caused by prying.
Solution: Companies must improve the quality of mold repairs. 1590XX 1790NS Cast Aluminum Enclosure products molds must be nitrided regularly and strictly implemented nitriding processes. Strictly control the quality of the chemical composition of the ingot; improve the quality of mold repair, improve the precision of mold manufacturing, and regularly nitrate the mold and strictly implement the nitriding process parameters.

2. Bumps during stamping and CNC processing: improper operation, 1590XX 1790NS Cast Aluminum Enclosure products encountered mold fixtures, machine tools, etc. when picking up the parts; the processed aluminum alloy enclosures are not stacked with the fashion trays; operation Improperly, the aluminum alloy shell fell.
Solution: Place the profiles reasonably in the material frame to avoid mutual friction as much as possible. Handle with care during the production process of aluminum housing to avoid scratches caused by human factors.

3. Bumps and scratches during the circulation of various processes: improper stacking and collapse; 1590XX 1790NS Cast Aluminum Enclosure products vigorously handling; there are sundries in the packaging material of the aluminum alloy enclosure, and the sundries and products rub against the products during the transfer process Cause scratches.
Solution: Use soft felt and plastic strips to separate the aluminum alloy shell from the auxiliary equipment to reduce the friction between them and cause damage. Clean the working belts such as the discharging track and the swing bed in time to prevent debris from affecting the quality of the aluminum housing production and processing.

4. Caused by improper anodizing operation: the anodizing is caused by touching the hanger when hanging up and down; by touching the oxidation tank when entering and exiting the tank; the product is falling out of the tank.
Solution: 1590XX 1790NS Cast Aluminum Enclosure products have been anodized and put on a protective "coat". Because the chemical properties of the anodized film are very stable in the natural environment, it can provide corrosion protection for the aluminum alloy shell. A reasonable grasp of the high hardness of the anodized film will make the aluminum alloy shell have a low roughness and a smooth surface, which greatly improves the wear resistance of the aluminum shell. If various organic and inorganic dyes are added during the anodization process, the The anodic oxide film has a color, which brings a beautiful appearance to the aluminum housing.

5. The abrasion on the inner surface of the extruded product during the extrusion process is called the inner surface abrasion. 1590XX 1790NS Cast Aluminum Enclosure products The reasons for the internal surface damage are: 1. Extrusion needle is stuck with metal; 2. The temperature of the extrusion needle is low; 3. The surface quality of the extrusion needle is poor, with bumps; 4. Extrusion temperature and speed control Not good; 5. Improper ratio of extrusion lubricant.
Solution: 1. Increase the temperature of the extrusion cylinder and the extrusion needle, and control the extrusion temperature and extrusion speed; 2. Strengthen the filtration of lubricating oil, check or replace the waste oil frequently, and apply the oil evenly and appropriately; 3. Maintain The surface of the wool is clean; 4. Replace the unqualified mold and extrusion needle in time, and keep the surface of the extrusion tool clean and smooth.
