LPDC
Extending Mold Life and Preventing Corrosion in Aluminum Alloy Wheel Production
KW-NT Applications: Low Pressure Die Casting (LPDC)
Failure Analysis & Countermeasures
The Problem: Corrosion
In Low Pressure Die Casting (especially for aluminum alloy wheels), a common issue is the formation of chemical intermetallic compounds between the high-temperature aluminum melt and the mold steel.
The Countermeasure: KW-NT
By implementing KANWAY's specialized Nitriding Treatment (KW-NT) alongside optimized mold cooling design, we effectively prevent chemical erosion and significantly extend service life.
Performance Showcase: Aluminum Alloy Wheel Mold
Standard Mold Life Severe corrosion appearing after only 2,000 ~ 4,000 shots.
With KW-NT Application The gate area remains intact even after 50,400 shots.
Conclusion:
KW-NT demonstrates a significant effect on reducing damage in LPDC molds,
drastically lowering maintenance costs and increasing production efficiency.
