When a part is created by die-casting, excess material can remain connected to the part. This excess material is typically thin and lighter weight. This material is called flash or flashing. This is a common issue in aluminum and zinc die-casting.

Wheel blasting and mass finishing are frequently used in flash removal applications. Air blasting and hand work with air tools or files can be used as well but do not tend to provide adequate throughput.
