Tam sim no, hauv daim ntawv thov ntawm cov cuab yeej siv tshuab, xeb siv cov roj hluav taws xob tshwj xeeb yog vim muaj cov khoom lag luam tshwj xeeb uas pom los ntawm cov neeg tsim khoom {}}} cov khoom siv tawm ntawm stamping feem ntau muaj cov pa roj oxidation tsis pub dhau tom qab kev tsim khoom thiab kev ua haujlwm, lossis cov roj tais diav thiab cov roj tu rau ntawm qhov chaw stamping.
Nyob rau lub sijhawm no, kev ua cov nroj tsuag yuav khaws thiab rov ua cov yeeb yaj kiab, yog li cov roj tsheb thauj mus los ntau dua li 1 xyoos lub sij hawm .
Yog tias cov neeg siv khoom xav siv roj antioxidant, nws raug pom zoo kom siv viscient {} Tus neeg siv khoom lag luam tsis muaj txiaj ntsig thiab tsis zoo} cov kab thaiv lossis tsis xwm yeem sab hauv chaw nyob sab hauv tsev yog due to the raw material and deformation of the stamping die. Be sure to get rid of it. In the usual manufacturing, there are situations where the specifications of the punch pins are large or small and the specifications of the punch pins vary greatly. Design scheme specifications of convex drainage matrix.
Qhov kev tsim kho ntawm kev tsim khoom thiab kev ua haujlwm thiab cov khoom siv sib tw ntawm cov khoom siv raw ntawm cov khoom siv raw, thiab cov khoom siv muaj zog ntawm cov khoom siv raw rau cov yas deformation ntawm cov khoom siv raw, uas yuav ua rau lub qhov loj me me yog txo qis, thaum lub taub hau ua haujlwm tau loj dua, thiab cov kev qhia tshwj xeeb ntawm cov punching koob yuav yog me me, hauv lub neej tshwj xeeb kev coj ua .
