Casting die surface defects


Casting die surface scratch is a very common problem. The main reason lead to the defects are as follow:

1.    Die casting surface was damaged

2.    No angle or angle is too small of the mould opening direction

3.    Casting temperature is too low or too high, mould temperature over-hihgh will lead to Alloy liquid adhesive.

4.    Aluminum alloy composition iron content lower than 0.8%

5.    Cooling time is too long or too short

As find out the defects reason, So the solution to solve this problem is to fix the cavity surface damage, correct the angle, adjust the casting temperature to 180-250℃,and adjust cooling time, etc.
