Kev txhaj tshuaj molding yog txheej txheem tsim khoom siv dav hauv kev tsim cov khoom siv me me. Cov txheej txheem cuam tshuam nrog kev txhaj tshuaj molten rau hauv lub pwm kab noj hniav uas cov khoom sib zog ua rau cov khoom xav tau. Txawm li cas los xij, zoo li txhua txoj kev tsim khoom, kev txhaj tshuaj molding muaj nws cov nyom. Kev tsis xws luag tuaj yeem tshwm sim thaum lub sijhawm txhaj tshuaj molding txheej txheem, cuam tshuam rau qhov zoo thiab kev ua haujlwm ntawm cov khoom kawg.
1. Kev txhaj tshuaj luv luv
Ib qho tsis xws luag hauv kev txhaj tshuaj molding ntawm cov khoom siv me me yog "kev txhaj tshuaj luv luv." Qhov no tshwm sim thaum cov khoom molten tsis ua kom tiav cov pwm kab noj hniav, uas ua rau ib qho tsis tiav los yog undersized. Kev txhaj tshuaj luv luv tuaj yeem tshwm sim los ntawm ntau yam, xws li kev txhaj tshuaj tsis txaus, tsim pwm tsis zoo, lossis cov khoom siv kub tsis txaus. Txhawm rau tiv thaiv kev txhaj tshuaj luv luv, kev txhaj tshuaj tsis zoo yuav tsum tau ua kom zoo thiab tsim pwm tsim thiab cov khoom siv kub kom ntseeg tau.
2. Cov cim dab dej
Lwm qhov tsis xws luag yog "cov cim dab dej," uas yog kev nyuaj siab lossis dents nyob rau saum npoo ntawm qhov molded. Thaum cov khoom txias thiab shrinks tsis sib npaug, cov cim dab dej yuav tshwm sim, ua rau muaj kev nyuaj siab hauv cheeb tsam. Qhov kev tsis zoo no feem ntau yog tshwm sim los ntawm kev tuav tsis txaus, lub sijhawm txias tsis txaus, lossis tsim lub rooj vag tsis zoo. Yuav kom txo qis cov cim dab dej, nws yog ib qho tseem ceeb kom ua kom zoo dua qhov ntim thiab txias theem ntawm cov txheej txheem txhaj tshuaj molding thiab xav txog kev hloov kho qhov rooj.
3. Flash
"Flash" yog lwm qhov tsis xws luag hauv kev txhaj tshuaj molding yam ntxwv los ntawm cov khoom siv ntau dhau los ntawm txoj kab sib cais lossis ntug ntawm pwm. Burrs tuaj yeem tshwm sim vim kev txhaj tshuaj ntau dhau, hnav cov pwm pwm, lossis tsis txaus clamping quab yuam. Txhawm rau tiv thaiv flashing, nws yog ib qho tseem ceeb kom tsis tu ncua thiab tshuaj xyuas cov pwm, ua kom lub zog clamping zoo, thiab ua tib zoo saib xyuas kev txhaj tshuaj.
Hauv kev xaus, thaum txhaj tshuaj molding yog cov txheej txheem tsim tau zoo rau cov khoom siv hauv tsev me me, nws yog ib qho tseem ceeb kom paub txog qhov tsis xws luag uas tuaj yeem tshwm sim. Los ntawm kev nkag siab thiab daws teeb meem xws li kev txhaj tshuaj luv luv, cov cim dab dej thiab flash, cov tuam ntxhab tuaj yeem txhim kho qhov zoo thiab sib xws ntawm lawv cov khoom txhaj tshuaj molded. Los ntawm kev ua tib zoo ua kom zoo dua qub thiab kev saib xyuas pwm, cov kev tsis zoo no tuaj yeem txo qis, ua kom cov khoom siv me me ua tau zoo los ntawm kev txhaj tshuaj molding.
