Cov teeb meem tshwm sim thaum lub sij hawm stamping txheej txheem muaj xws li wrinkling, tearing, thiab springback. Wrinkling yog tshwm sim los ntawm kev ntxhov siab ntau dhau thaum lub sij hawm tsim thiab tuaj yeem txo tau los ntawm kev kho qhov khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob Tearing tshwm sim los ntawm kev ntxhov siab ntau dhau thaum lub sij hawm sib sib zog nqus nqus; qhov no tuaj yeem tiv thaiv tau los ntawm kev xaiv cov ntaub ntawv nrog cov ductility zoo dua, kho cov txheej txheem tsis zoo, lossis ua kom cov fillet radii. Springback hais txog qhov sib txawv ntawm qhov sib txawv ntawm qhov khoov los ntawm cov khoom siv elastic rov qab; nws qhov cuam tshuam tuaj yeem txo qis los ntawm cov txheej txheem xws li dhau- khoov lossis kho cua sov.
Stamping yog dav siv nyob rau hauv ntau yam lag luam. Hauv kev lag luam tsheb, nws yog siv los tsim lub cev tsheb, chassis, thiab cov khoom siv cav. Nyob rau hauv aerospace, nws yog siv rau zus tau tej cov airframe structural ntsiab thiab engine qhov chaw. Kev lag luam hluav taws xob thiab hluav taws xob siv hluav taws xob stamping los tsim cov khoom siv hlau zoo xws li cov khoom sib txuas thiab cov khoom siv hluav taws xob, thaum cov khoom siv hauv tsev siv feem ntau rau cov casings thiab sab hauv. Qhov dav dav ntawm cov ntawv thov no qhia txog qhov tseem ceeb ntawm cov txheej txheem stamping.
