Why Aluminum Casting Molds Need Regular Stress Relief Maintenance
Long-term cyclic high-temperature operation will accumulate residual internal stress inside aluminium alloy casting mould, and regular stress relief maintenance is essential to maintain mold precision and service life.
Mold fatigue detection data shows that continuous production without stress relief will accumulate massive internal stress, causing precision deviation after 25,000 casting shots.
Low pressure die casting mold working in alternating temperature environments is prone to invisible internal stress concentration, which gradually evolves into micro-cracks and macroscopic deformation.
Custom low pressure die casting mold after professional stress relief treatment reduces thermal fatigue damage by 37%, delaying crack generation and propagation speed.
Wheel casting mold with regular stress relief maintenance keeps dimensional tolerance stable within 0.01mm for a longer service cycle.
High durability LPDC die for mass production needs integral stress relief annealing treatment every 20,000 shots to eliminate accumulated working stress.
Automotive casting tooling for high-precision EV parts requires more frequent stress detection, as tiny deformation will affect part assembly accuracy.
Foundry tooling lacking stress relief maintenance has a 32% higher probability of sudden failure in peak production periods, causing production line shutdown losses.
Stress relief treatment will not damage existing mold structure and precision, effectively repairing invisible fatigue damage caused by cyclic production.
xinfeng provides targeted stress relief maintenance cycles for different mold types, helping foundries avoid premature mold failure and precision attenuation.
