What is the trimming in die casting?

21/04/2023

The final step in the die casting process is trimming. While the metal is cooling, the excess metal in the sprue and runner must be removed along with any flash that has transpired. This extra material is then trimmed away from the final casting. The trimmed sprue, runners, and flash can then be recycled and reused in the die casting process.
