Tam sim no, hom khoom siv cib nrov tshaj plaws nyob rau hauv kev ua lag luam yog lub tshuab tsis siv neeg tsis siv lub tshuab cib, uas muaj cov yam ntxwv ntawm kev ceev molding ceev thiab cov nyhuv ceev. Yog li ntawd, ntau lub tuam txhab khib nyiab khib nyiab tau qhia txog hom tshuab thiab khoom siv no. Raws li cov yam ntxwv tseem ceeb ntawm hom khoom siv no, kuj tseem muaj cov ntsiab lus hauv qab no rau kev siv.

Ua ntej, kev ua haujlwm ntawm cov cuab yeej.No cov khoom siv hluav taws xob cib, nrog cov khoom sib xyaw ua ke. Nws cov khoom sib xyaw tuaj yeem ua tiav tsis siv neeg sib xyaw, tib lub sijhawm, hauv cov txheej txheem sib xyaw, nws kuj tuaj yeem siv rau qee cov ntaub ntawv yas, lossis cov khoom siv tawv tawv semi qhuav rau kev sib xyaw ua ke. Hauv cov txheej txheem sib tov, tsis pub rov noj dua. Vim hais tias kev pub mis rov qab tuaj yeem ua rau lub nra ntawm lub tshuab tsis siv neeg tsis siv lub tshuab cib, ua rau lub tshuab thaiv lossis lub suab nrov dhau. Tau kawg, tom qab lub thoob sib xyaw ua tiav tiav, nws yog ib qho tsim nyog yuav tsum ua kom tiav qhov zoo txuas ntxiv. Tau kawg, tom qab lub sijhawm sib tov txaus, qhov rov qab tso tawm tuaj yeem nqa tawm, thiab cov khoom sib xyaw tuaj yeem xa tawm mus rau qhov sib txawv, kom paub txog cov hauv qab no molding thiab extrusion Nias cov kauj ruam. Hauv cov txheej txheem no, lub nplhaib iav ua lub luag haujlwm zoo, nws yog tus pabcuam tseem ceeb ntawm kev sib xyaw, tab sis kuj yog ib qho tseem ceeb ntawm cov kabmob kom paub txog kev ua haujlwm dawb ntawm lub tshuab.

Thib ob, cov peev txheej ntawm kev siv cov khoom siv.Nyob rau hauv qhov kev pom ntawm qhov kev thov ntawm lub tshuab tsis siv neeg tsis siv lub tshuab cib, nws yog qhov pom tseeb tias cov kws tshaj lij kuj tau ua cov ntsiab lus. Lawv xav tias hom kev tsim khoom thiab kev teeb tsa no yog qhov tsim nyog rau kev siv cib ntawm qee qhov txuas txuas lossis qee qhov chaw tsim kho. Tau kawg, qee qhov chaw tsim khoom loj kuj tuaj yeem siv tau, tshwj xeeb tshaj yog cov pob zeb ua vaj huam sib luag tuaj yeem ua kom tsim nyog siv cov cib no. Lawv qhov kev thov yog qhov dav, thiab tib lub sijhawm, kev muag khoom ntawm cov khoom pov tseg no tau nthuav dav infinitely.

Thib peb, lub ntsiab zoo ntawm cov khoom siv.Raws li peb txhua tus paub, lub tshuab tsis siv neeg tsis siv lub tshuab cib yog cov khoom siv ua cov cib siab heev. Cov cuab yeej zoo li no zoo nkauj dua nyob rau hauv tsos thiab paub txog qhov tsis siv neeg tsim tag nrho. Nyob rau tib lub sijhawm, nws cov duab yog me me. Yog li ntawd, thaum peb siv nws, nws yuav tsis siv ntau qhov chaw, tib lub sijhawm, nws yooj yim txav, yog li nws tuaj yeem siv ntau zaus hauv ntau qhov chaw ua haujlwm. Tau kawg, qhov kev siv ntawm cov khoom siv tau mus txog 95%. Lub caij no, ntau yam khoom pov tseg raw cov ntaub ntawv tuaj yeem muab piv rau kev tshawb fawb kom paub txog qhov sib xyaw ua ke thiab nias ntawm lub thoob sib xyaw, thiab thaum kawg cov cib uas tuaj yeem siv dav hauv kev ua lag luam yuav raug tsim. Yog li ntawd, nws cov peev txheej siv tau ntau ntxiv.

Vim tias cov kws tshawb fawb tau kawm cov qauv ntawm lub tshuab tsis siv neeg tsis siv lub tshuab cib, nws cov qauv tsim nyog thiab yooj yim dua, thiab kev saib xyuas kuj yooj yim heev. Tau kawg, qhov muag pom tshaj plaws yog qhov ua tau zoo ntawm cov cuab yeej siv tau zoo heev thaum nws siv. Kev txhim kho ntawm kev tsim khoom ua rau cov chaw tsim khoom txuag lub sijhawm thiab lub zog ntau dua, yog li txhim kho qhov chaw ntawm cov txiaj ntsig zoo. Yog lawm, molding yog ceev thiab cov nyhuv yog ceev, uas ua rau lub lag luam nrov heev rau hom cib ua khoom siv. Ntau lub tuam txhab tau pib yuav thiab qhia cov cuab yeej siv, uas tau txhim kho kev ua haujlwm zoo ntawm cov khoom pov tseg hauv Suav teb. Niaj hnub no, ntau pua txhiab tons ntawm cov khoom pov tseg yuav tsis cuam tshuam rau ib puag ncig, hloov pauv, nws yuav raug muab tso rau hauv kev tsim khoom dua kom paub txog cov khoom lag luam thib ob. Tau kawg, peb kuj yuav tsum tau ua raws li cov kev cai ntawm kev nyab xeeb thaum siv cov cuab yeej siv, kom tsis txhob ua rau cov khoom puas tsuaj vim qhov muag tsis pom ntawm cov khoom tsis paub siv cov cuab yeej, ua rau kev txhim kho cov nyiaj tau los, uas yog ib qho pov tseg rau cov tuam txhab tsim khoom.
