Thaum lub sij hawm stamping, vim muaj qhov sib txawv ntawm qhov sib txawv, cov khoom yog ncab ntawm ib sab ntawm qhov tuag (cov khoom siv warps upward) thiab compressed rau sab ntawm lub punch. Thaum siv lub phaj nyem, siv lub phaj nyem los txhawm rau txhawm rau txhawm rau tiv thaiv cov khoom ntawm qhov tuag los ntawm kev deformed. Lub sijhawm no, lub xeev kev ntxhov siab ntawm cov khoom hloov raws li. Raws li lub zog quab yuam ntawm lub phaj nyem nce, cov khoom ntawm tus txiv neej ntawm qhov tuag yog stretched (compressive quab yuam yuav txo qis), thiab cov khoom ntawm lub concave nto ntawm cov tuag yog compressed (tensile quab yuam yuav txo). Flipping ntawm stamped qhov chaw yog tshwm sim los ntawm stretching ntawm cov khoom nyob rau saum npoo ntawm cov tuag. Yog li ntawd, thaum stamping, nias thiab compressing cov khoom yog tus yuam sij los tiv thaiv cov stamped qhov chaw ntawm tig thiab twisting. Ua thiab tiv thaiv kev tig thiab sib tw ntawm qhov chaw stamped thaum khoov: 1. Ua los ntawm burrs ntawm stamped qhov chaw tsim thaum lub sij hawm stamping. Nws yog ib qho tsim nyog los kho qhov perforation ntug thiab xyuas seb qhov sib txawv perforation puas txaus. 2. Thaum lub sij hawm stamping, cov khoom perforated tau tig thiab twisted, ua rau tsis zoo tom qab khoov. Qhov teeb meem no yuav tsum tau daws ntawm qhov chaw nres tsheb stamping thiab xuas nrig ntaus. 3. Ua los ntawm instability ntawm stamped qhov chaw thaum khoov.
