Mould qhov sib txoos
Hauv txoj kev sib tsoo thiab hluav taws xob ua haujlwm, cov workpiece yuav tsum tau magnetized mus rau ib qhov twg, nrog qaug zog muaj zog dag zog, thiab nws yog yooj yim rau nqus qee me me sundries. Yog li, ua ntej sib dhos, yuav tsum tau ua kom tiav cov teeb meem ntawm qhov ua hauj lwm thiab qhov yuav tsum tau ntxuav nrog cov ethyl acetate.Thaum tus txheej txheem sib dhos: (1) nkag siab txog lub rooj sib txoos ua ntej thiab npaj txhua yam khoom (2) ntawm txhua qhov; (3) xyuas qhov tseeb qhov tseeb ntawm txhua qhov thiab ua kom pom tseeb tias yuav tsum muaj kev sib koom tes (4) ua kom tiav cov cuab yeej uas yuav tsum tau siv, thiab pib pib lub khob (5) (7) qhib thiab kaw lub pwm, thiab xyuas seb qhov pwm ua haujlwm puas ruaj khov rau kev txhim kho (mold block); (6) ua ke nrog cov punch thiab tuag, thiab kho qhov chaw ntawm txhua lub phaj; .
