Nrog rau kev pab ntawm lub cua sov, cov yas hauv lub gating system yuav tsis ua kom tiav, thiab yuav tsis raug tso tawm ntawm cov khoom, yog li ntawd nws tseem hu ua tus neeg tsis yog khiav. Qhov zoo tshaj plaws rau cov khoom siv kub kub molding compound nta: 5) Kev ntsuas kub ntawm qhov nruab nrab yog qhov dav hlau . Thaum tsis muaj kub, qhov fluidity zoo, thiab thaum muaj kev kub, nws muaj kev thermal stability zoo. 6) Mob siab rau siab, tsis muaj qhov siab thiab tsis ntws, tab sis nws muaj peev xwm khiav tawm thaum lub siab raug siv. 7) Lub tshav kub yog qhov zoo kom nws thiaj li tau txias txias hauv pwm. Muaj kub khiav cov yas yog PE, ABS, POM, PC, HIPS, PS. Muaj ob hom kub khiav uas siv ntau zaus: 1) cua sov khiav cov pwm 2) cov pwm ntawm cov ntoo khiav hauv tsev.

Cov phom hlau siv nyob rau hauv cov txheej txheem sab nrauv yuav tsum tau kub-kho tom qab tau yuav rov qab, xws li quenching thiab carburizing, thiaj li ua tau raws li cov tseev kom siv. Xws li ib qho kev txhaj tshuaj pwm hu ua lub pwm tawv. Piv txwv, lub puab pwm xyaum H13 steel, 420 steel, thiab S7 steel.
(3) Muag hom (hauv qab 44HRC)
Cov hlau uas siv rau cov txheej txheem hauv chav yuav siv tsis tau ntxiv cov khoom kho kub tom qab nws yuav. Qhov kev txhaj tshuaj no hu ua mos pwm. Piv txwv, P20 steel, ace steel, 420 steel, NAK80, aluminium, thiab beryllium tooj liab yog siv rau cov txheej txheem puab.
