Will casting-china.com' target='_blank'>aluminum die casting foam after electroplating?
For large die-casting parts, it is required that the pressure resistance is strong, the surface electroplating, the general selection of aluminum alloy materials, but the occurrence of foaming after electroplating, we analyze the cause of foaming, I hope you can help after reading.
First, increase the mold temperature
1. Mold surface temperature is not enough
After increasing the temperature, the aluminum alloy material is more easily adhered to the mold surface, which can reduce the generation of bubbles .
2. Thermal stress reduction
Temperature and pressure need to be controlled to reduce the generation of thermal stress .
3. Reduce material temperature fluctuation
It is necessary to control the temperature of aluminum alloy materials and reduce fluctuations, and the method of constant temperature die casting can be adopted to add thermostat to the aluminum alloy materials to control temperature fluctuations .
Second, optimize the die casting process
1. Choose the right die casting machine and material
Choose die casting machines and materials that meet the process, so that aluminum alloy materials can be adhered to the surface of the mold .
2. Optimize process parameters
Proper adjustment of die casting pressure, die casting temperature, die casting speed and other parameters. The aluminum alloy material can be adhered to the surface of the mold .
3. Adjust process parameters such as die casting temperature and pressure
Under the premise of ensuring the full solidification of aluminum alloy material, the temperature and pressure parameters of die casting are appropriately reduced .
Third, strengthen mold maintenance
1. Check mold wear regularly
The uneven surface will cause the aluminum alloy material to be difficult to adhere to the mold .
2. Clean the mold
The dirt on the surface of the mold needs to be cleaned regularly to completely remove the dirt and impurities on the surface of the mold .
3. Apply lubricating grease
In the process of aluminum alloy die-casting, the appropriate amount of lubricating oil is applied to reduce the friction on the mold surface, but it can not be applied too much, otherwise it will affect the adhesion of aluminum alloy materials .
