This article explores how geometric constraints in automotive lighting components selectively amplify existing residual stress. It explains why geometry does not create stress but determines whether stress can redistribute or become trapped, influencing long-term stability and process limits. Read More

This article explains why cooling systems in automotive lighting molds should be viewed as stress-control structures rather than efficiency tools. It examines how early cooling decisions lock residual stress into parts and define long-term stability and process robustness. Read More

This article examines how gate design decisions in automotive lighting molds introduce and lock internal stress into parts. It explains why gates that appear acceptable during trials can later reduce stability, leading to narrow process windows and increased dependence on process control. Read More
