This business unit specializes in small, complex, flash free zinc parts. For small zinc die castings, this process offers advantages over conventional processing including:
-Faster cycle times
-Tighter tolerances
-Instant response to process variation
-Lower overall cost
-Faster turn around times
Tumbling, vibration, or thermal de-burring processes replace costly trimming operations.
