3. Pem hauv ntej txias ntawm cov khoom ntws
Thaum lub sij hawm txhaj tshuaj molding cov txheej txheem yuav sai sai yuav txias sai sai thaum muaj cov pwm txias, ua ib txheej ntawm cov khoom siv txias. Txheej no cov khoom siv txias yuav thaiv cov khoom siv, khiav, ua rau cov khoom lag luam uas yooj yim, ua rau nkag tau cov pwm kom tsis muaj peev xwm nkag mus rau hauv cov kab noj hniav yooj yim, ua rau muaj cov khoom tsis muaj peev xwm. Txhawm rau kom daws tau cov teeb meem no, qhov loj ntawm cov khoom txias zoo tuaj yeem nthuav tawm kom haum kom haum cov khoom txias ntxiv thiab tiv thaiv lub rooj vag thiab khiav.
4. Tsis tsim nyog r tus nqi ntawm nozzle thiab pwm qhov ncauj
Qhov tsis sib xws ntawm R qhov tseem ceeb ntawm lub nozzle ntawm lub nozzle thiab kev tuag tuaj yeem ua rau muaj kev tiv thaiv tau zoo, yog li txo cov yaj tau zoo thiab ua kom muaj qhov tsis txaus. Txhawm rau kom daws tau qhov teeb meem no, nws yog ib qho tsim nyog los xyuas kom meej tias R qhov tseem ceeb ntawm lub nozzle thiab pwm muaj kev sib xws los txo cov yaj ntawm cov txheej txheem txau.
5. Ntau dhau kev pub mis
Txawm hais tias muaj kev pub mis tsis txaus yuav ua rau tsis muaj peev xwm filling, ntau dhau ntawm kev pub mis kuj tuaj yeem tsim teeb meem. Thaum cov nyiaj pub mis loj dhau lawm, qhov kev kub siab ntawm cov yaj yuav txo qis vim tias muaj ntau yaj yuav tsim kev tiv thaiv ntxiv thaum ua cov txheej txheem kev nqus. Txhawm rau kom daws cov teeb meem no, nws yog qhov tsim nyog los txo cov kev pub mis thiab siv cov kev pub mis rau kev pub mis throttle plugs kom tswj tau cov roj nplua nyeem ntawm cov roj nplua nyeem.
6. Lub nozzle kub yog tsawg dhau
Lub nozzle kub uas dhau heev tuaj yeem ua rau qhov kub ntawm cov txiv hmab kom qeeb qeeb thaum lub suab txau, yog li txo cov txiv hmab txiv ntoo ntawm cov melt thiab ua rau muaj kev tsis txaus. Txhawm rau daws cov teeb meem no, nws yog ib qho tsim nyog los cais cov nozzle los ntawm pwm thaum pwm thaum pwm kom txo cov tshuaj pwm kub ntawm lub nozzle. Nyob rau tib lub sijhawm, nws yog ib qho tsim nyog yuav kom ntseeg tau tias qhov kubzzle kub nyob tsis dhau ntawm cov txheej txheem ntawm cov txheej txheem.
7. Unbalanced pouring system
Nyob rau hauv ib tug ntau kab noj hniav pwm, yog tias tus qauv ntawm lub zog pouring yog tsis sib xws, nws yuav ua rau cov kab noj hniav deb ntawm lub ntsiab khiav kom tsis tuaj yeem sau. Txhawm rau kom daws tau qhov teeb meem no, lub zog nchuav tuaj yeem sib npaug ntawm kev kho lub rooj vag dav lossis yog li cov khoom ntws tuaj yeem sau ib kab noj hniav.
8. Cov khoom kub tsis tshua muaj
Tsis tshua muaj pwm txias tuaj yeem kho cov txheej txheem solorification ntawm cov yas, yog li txo nws cov kua txiv. Thaum cov pwm kub tsawg dhau lawm, cov ntws ntawm cov yas yaj hauv cov pwm kab noj hniav yuav raug txwv, ua rau muaj kev sau tsis muaj peev xwm. Txhawm rau kom daws tau qhov teeb meem no, nws yog ib qho tsim nyog los nce cov pwm kub kom qeeb ua kom qeeb ntawm cov yas thiab txhim kho nws cov kua txiv.
9. Cov kev txhaj tshuaj thiab nrawm
Txhaj siab thiab nrawm yog qhov tseem ceeb cuam tshuam rau cov nyhuv txhaws. Thaum kev txhaj tshuaj siab yog tsis txaus, lub siab ntawm cov yas yaj hauv cov pwm kab noj hniav tsis txaus kom kov yeej cov kev ntws tawm tsam; Thaum kev txhaj tshuaj ceev tsis txaus, lub sijhawm txaus ntawm cov yas yaj yuav tsum ntev, yog li nce qhov kev pheej hmoo ntawm solidification. Txhawm rau kom daws tau qhov teeb meem no, nws yog ib qho tsim nyog los nce kev txhaj tshuaj tiv thaiv kev kub siab thiab ceev kom paub tseeb tias cov yas yaj tau du qha cov pwm puab.
10. Kev txhaj tshuaj tiv thaiv yog luv heev
Kev txhaj tshuaj luv luv tuaj yeem ua rau cov khoom siv tsis txaus, vim tias tsis muaj qhov chaw txaus rau kev nqus tag nrho cov khoom siv tshuaj pleev thaum lub sijhawm txhaj tshuaj. Txhawm rau kom daws tau qhov teeb meem no, nws yog qhov tsim nyog los kho qhov ntev ntawm kev txhaj tshuaj tiv thaiv thiab kho cov particle partic paus raum kom ntseeg tau cov khoom noj kom txaus.
