Tsim cov txheej txheem ntawm cov menyuam cov txheej txheem: Lub deformation ntawm cov txheej txheem molding yog txwv los ntawm ib txheej ntawm cov yob nyob rau hauv txoj kab ntsug. Nws yog ib txoj kev tsim uas tau sib xws nrog cov yam ntxwv ntawm theem molding thiab dov cov menyuam molding.
Nws cov yam ntxwv yog:
(1) Cov yob ntawm cov yob ntawm lub tander steel tsim cov nyhuv stretching longitudinal yog me me, ua rau sab stretch nyob rau hauv lub xeev yam tsawg kawg nkaus.
(2) Cov pab pawg neeg cov menyuam tuaj yeem siv los ua ntau yam tshwj xeeb ntawm cov kav dej tsis tas yuav hloov cov menyuam, uas yog qhov zoo sib xws.
(3) Cov menyuam pawg yog cov menyuam tsis muaj zog, thiab kev sib txhuam kev siv me me, yog li lub zog xav tau rau kev tsim yog me me.
