The Heat Treatment of Large Dies Involves Risks

2022-11-08


Large die casting dies are often characterized by large cross-sectional differences.
Risks: 
  • Different heating rates of the various cross sections => different soaking times of these areas at 
hardening temperature. This results in the risk that thin-walled cross sections are overtimes 
(coarse grain, embrittlement). 
  • Different quenching rates in the different cross sections (=> risk of cracking, insufficient 
microstructure)
