Background:

Aluminum powder is easy to be created during mass production, resulting in scoring on the product surface, which is a common problem in mass production of aluminum parts.

We summarized the reasons why panel with scoring issue below.

1. The aluminum powder created in the die when form which caused high temperature sintering on the surface due to long move distance.

2. Insufficient lubrication and high friction caused scoring issue. 

3. Forming gap is less than material thickness to form an extrusion condition, which is easy to cause scoring.

Countermeasure:

1. Use fine sandpaper or fine oil stone to remove the attachment and polishing.

2. Add a proper amount of special lubricating oil for aluminum parts in the die.

3. Increase forming gap tolerance. (lower die polishing)

We cleaned the die with fine sandpaper or fine oil stone during part production. 

After treatment, we confirmed that the surface coating is not damaged.
