While high-strength steel plates can improve the strength of parts, their high yield strength and severe work hardening result in a significant increase in springback.
Physical phenomena are inevitable during the stamping process for car seat parts, but they can be kept within acceptable limits through systematic process optimization, precise mold design, advanced simulation technology, and strict material control.
Automobile chassis and other structural parts often feature complex three-dimensional curved surfaces and are often made of high-strength or ultra-high-strength steel to meet load-bearing and crash safety requirements.
The shaping process is the last line of defense for springback compensation. For parts that have already rebounded, a second correction can be performed by adding a shaping sequence.
In the backbone of the modern automotive industry, high-strength, high-performance parts stamping technology, known as the "precision art of metal shaping," quietly forges the cornerstone of vehicle safety and performance.
For complex support structures, progressive or progressive die technology is often used, completing multiple steps within a single die set and reducing positioning errors caused by intermediate transfers.
