Dab tsi yog pwm koob? Cov yam ntxwv yog dab tsi?
Raws li paub tag nrho, cov ntaub moulds siv rau hauv kev txhaj tshuaj yas molding yog hu ua cov tshuaj molding pwm, los yog txhaj pwm rau luv luv.
Nrog rau kev lag luam ntawm kev lag luam ntawm kev lag luam, qhov kev thov khoom yas yog nce ntxiv, thiab cov khoom yas nrog cov cwj pwm tshiab, zoo dua, kev ua tau zoo dua thiab ntau txoj hauv kev tsim tawm.
Txhaj tshuaj yog tsim los ntawm kev molding.Yog muaj ntau txoj hau kev, thiab kev txhaj tshuaj molding yog ib qho tseem ceeb ntawm txoj kev ua tus qauv, nws cov khoom siv nrog kev ncaj ncees thiab cov duab nyuab, zoo sib xws, khoom tsim tau thiab cov khoom qis, kev thov thiab sab nrauv txoj kev loj hlob.
Raws li lub cuab tam tseem ceeb ntawm kev txhaj tshuaj molding ua, yog ib qhov kev txhaj mould, qhov zoo, qhov tseeb, kev voj voog thiab kev txhaj tshuaj molding ntau lawm cov txheej txheem ntawm cov theem kev siab thiab qis, ncaj qha rau kev txhaj tshuaj molding khoom, ntau lawm, nqi , thiab kho dua tshiab ntawm cov khoom.Yog li no, cov tshuaj pwm plays plays lub luag haujlwm tseem ceeb hauv cov khoom tsim tawm.Thaum hais lus, txhaj tshuaj pwm nta cov nram qab no:
(1) tsim yog cov khoom tsis zoo yas polymer, nws cov yaj yog cov nplaum tsim, cov txheej txheem nquag hloov hloov nrog shear kev nyuab siab, tsho tus nqi, thiab cov txheej txheem khiav hauv macromolecular orientation raws li cov lus qhia khiav tawm.Nws yog ib feem ntawm qhov compression tom qab tag nrho cov kab noj hniav , thiab nyob hauv tus txheej txheem ntawm kev sib tw ntawm cov yas shrinkage yog qhov nyuaj heev, txhua feem ntawm cov pwm kab thiab cov kev sib txawv ntawm cov lus qhia sib txawv yog txawv, thiab ntau hom, cov qib ntawm cov ntxaib kuj muaj qhov sib txawv loj heev, yuav tsum yog tsim ntawm kev txhaj tshuaj pwm
Tshem nyiaj.
(2) raug tsim muaj cov nqi ntawm cov pwm uas yog tsim los ntawm cov qauv tsim ntawm cov khoom muag, cov khoom, txhua hom qauv pwm sib txawv, yog li no, nws tsis tuaj yeem siv rau hauv kev ua lag luam, nws tsis tuaj yeem ua rau ntau lawm .
Vim yog cov teeb meem ntawm kev tsim thiab ua khoom muag, lub neej ntawm mould yog ntev, thiab qhov tseem ua rau cov pwm pheej yig me me. Yog li ntawd, cov nqi tsim ntawm lub pwm yog siab.
(3) lub voj voog ntawm kev lag luam yog luv ntawm kev sib tw khoom tam sim no yog tsiv, yog li ntawd, txhua lub chaw tsim khoom muaj nyob rau hauv ib haiv neeg tawm tsam lub sij hawm, rau cov khoom muag kom sai li sai tau thiab ua peb qhov zoo tshaj plaws, uas yuav tsum tau txhaj pwm tsim, kev tsim mus rau kev tsim tawm ntawm txhua tus sim ua kom luv luv lub sijhawm.
Cov ntsiab lus ntawm kev txhaj tshuaj molding khoom zoo yog qhov nyuaj, yog qhov tseem ceeb ntawm qhov yuav tsum tau loj, qhov tseeb, thiab yog lub ntsiab tivthaiv, kev tsim cov pwm tsim thiab kev tsim coj los ua teebmeem loj, kom ua tiav thiab tsim nyog pwm kev tsim, yuav tsum yog ib tug tub rog zoo uas yuav, yuav tsum ua kom pom tseeb ntawm kev siv tshuab hluav taws xob
