Reasons for substandard performance and poor hardness of aluminum profile

Generally speaking, ultra-high mechanical performance is also high hardness, mechanical performance is not qualified corresponding to low hardness, mechanical performance is not qualified refers to the material in the stretching process of the anti-pull strength and yield strength does not meet the requirements;

The reason for the occurrence

1. When squeezing, the aluminum profile rod temperature and exit temperature are not up to standard

2. The cooling speed of the profile is not enough

3. Use the wrong stick

4. Time-caused furnace failure

Countermeasures.

1. Ensure that the process is under control

2. To ensure that the rod is not wrong, the whole process of production in the process of standard implementation, regular testing furnace temperature, do a good job of equipment maintenance

3. Ensure that the cooling equipment is intact and the aluminum profile can be cooled evenly
