How about the appearance quality of the drop-forged parts?

If there are defects on the surface of forgings such as cracks, folding, forging wounds, laminations, scars, slag, etc., they shall be executed according to the following regulations.

The surface of forgings that need mechanical processing, after inspection to confirm the depth of defects, can ensure that more than 50% of the machining allowance is left, it is allowed not to remove, but need to be agreed by the user.

No longer machined forging surface, the maximum depth of the refurbishment shall not exceed the lower deviation of the size of the place, and the refurbishment must be smooth.

When the depth of the surface defects of the forgings exceeds the machining allowance, the user's consent must be obtained if welding is required. After the defects are completely removed, the welding is carried out according to the appropriate welding procedures, and the quality of the welding should meet the user's requirements for the forgings.

Whether the surface of forgings should be cleaned up and the method of cleaning up should be agreed between the user and the manufacturer at the time of order.
