Sometimes China Die Casting is acceptable
Porosity varies in severity. Sometimes China Die Casting is acceptable, but most often it’s best to limit it as much as possible.
The most direct way to control for porosity is to work with all of your partners to create an efficient process for die casting, while ensuring the material you’re working with is of a high quality. Process monitoring should focus on equipment maintenance and stability, which can help guarantee an even and adequate amount of pressure throughout the casting.
