① It is caused by the side and corner of the mold, equipment, or worktable when opening the mold.
② The castings of each operation process are stacked.
③ Improper behaviour of each process, such as throwing.
④ During operation and transfer between processes, the castings were not separated and protected, or the castings collapsed.
⑤ During each operation procedure, such as die-casting pick hooks, picking pliers, files and punches in the cleaning process.
5 ways of avoiding “scratches”：
① When the casting is demoulded, be careful not to bump.
② Obey the operating instructions, the castings are not allowed to be stacked and must be neatly placed in the workstation equipment one by one.
③ Not allowed throwing the castings during production, and must be handled carefully.
④ Placed the castings must be protected separately, and the transfer must be slow to prevent them from collapsing or falling.
⑤ Using the tools correctly. It is not allowed to hook or pinch the casting body when removing them from the moulds.
