The straightness of an automotive steering rack directly determines the feel, presisjon, and noise control of a vehicle’s steering system. Starting from technical principles, this article provides an in-depth analysis of the key technical points in straightening S45C steering racks, inkludert: tackling massive initial deformation challenges (2.5-3mm), achieving high precision TIR (0.1mm) control, measurement difficulties

The straightness of an ejector pin directly impacts the overall lifespan of the mold and the quality of the injection-molded/die-cast parts. Starting from technical principles, this article provides an in-depth analysis of key technical points in straightening slender ejector pins, inkludert: process method comparison (manual/multi-roll vs. horizontal point straightening), high-precision measurement methods, process parameter optimization
