Zinc alloy die-casting offers excellent electroplating and coating performance, ideal for electronic components. However, issues arising during die casting mold design, mold manufacturing, pre-treatment, or plating can lead to various defects.

At Precisioner, with 16 years of expertise in die casting mold design and die casting mold manufacturing, we provide actionable solutions to common die casting problems—especially for zinc die casting and aluminum die casting projects.

1.Blistering


Casting Defects: Caused by impurities (Pb, Cd), porosity.
● Optimize die casting mold design; improve melting.
● Pre-Treatment: Due to part oxidation.
● Use anti-rust fluid; reduce storage time. Plating Defects: Poor layer adhesion.
● Increase copper thickness; filter plating solution.on.
