7075 aluminum tube in the production and processing may produce bubbles, then what is the cause?What are some good solutions?Next 7075 aluminum tube manufacturers to give you an analysis.
Causes:
1. 7075 aluminum tube liquid filling is too low, the initial injection velocity is too high, and air entrelling is easy to occur.
2. Improper mold design results in poor exhaust.
3, melting temperature is too high, high gas content, melting is unnecessary.
4, 7075 aluminum tube mold design temperature requirements are too high, mold retention time management is not enough, 7075 aluminum tube metal solidification time development is not enough, strength analysis is not early die opening, compression gas expansion.
5, the spraying time is too short, the mold surface residual moisture.
Solutions:
1. Adjust the technological parameters and injection speed.
2. Modify mold seeding, add overflow tank and exhaust box.
3. Reduce the regional mold temperature of product defects, so as to reduce the pressure effect of gas 7075 aluminum pipe.
4. Adjust the melting process of 7075 aluminum tube.
5. Prolong the mold retention time of 7075 aluminum tube and adjust the blowing time after spraying.
