1. Raw khoom xaivCov khoom siv tseem ceeb ntawm cov khob dej yas yog petrochemical plastics, suav nrog polyethylene (PE), polypropylene (PP) thiab lwm yam ntaub ntawv. Cov ntaub ntawv yas no muaj kev cuam tshuam zoo heev, pob tshab, kev ua haujlwm thiab lwm yam ntxwv, thiab tsim nyog rau kev tsim cov khob dej. Thaum xaiv cov khoom siv raw, ntxiv rau kev xav txog lub cev lub cev, ib puag ncig yam tseem ceeb kuj yuav tsum tau xav txog.
2. Kev ua thiab kev tsim
1. Txhaj tshuaj molding
Kev txhaj tshuaj molding yog cov txheej txheem tsim khoom siv ntau tshaj plaws rau lub raj mis dej yas. Nws txhaj cov khoom yas molten rau hauv pwm thiab tsim cov khoom molded tom qab txias thiab solidification. Lub khob dej uas tsim los ntawm txoj kev no muaj lub ntsej muag du thiab meej qhov ntev, thiab tseem tuaj yeem paub txog kev tsim khoom.
2. Tshuab molding
Tshuab moulding yog ib qho ntawm ntau txoj kev molding. Nws pressurizes thiab tshuab qhov pib tsim tubular ib feem nyob rau hauv qhov tuag, ua rau lub tubular ib feem nthuav thiab tsim nyob rau hauv tuag, thiab ces txiav thiab rub tawm. Txawm li cas los xij, cov txheej txheem tshuab moulding muaj cov kev xav tau siab ntawm cov khoom siv raw, kev ua haujlwm tsawg, thiab tsis haum rau ntau lawm.
3. Thermoforming
Thermoforming yog cov txheej txheem tsim khoom yooj yim tsim nyog rau kev tsim khoom me me. Nws muab cov ntawv yas tso rau hauv pwm, cua sov-nias cov ntawv yas los ntawm lub tshuab, thiab thaum kawg ua cov txheej txheem tom ntej xws li txiav thiab shaping.
3. Kev luam ntawv thiab ntim khoom Tom qab lub khob dej tau tsim, nws yuav tsum tau luam tawm thiab ntim. Kev luam ntawv feem ntau yog siv tus cwj mem luam ntawv, thiab cov qauv kev cai, logos, ntawv nyeem, thiab lwm yam tuaj yeem luam tawm ntawm lub khob dej. Ntim feem ntau suav nrog lub thawv ntim thiab pob tshab zaj duab xis ntim kom yooj yim cia thiab thauj mus los.
4. Cov cuab yeej siv ntau lawm
1. Txhaj tshuaj molding tshuab: siv rau kev txhaj tshuaj molding
2. Tshuab moulding tshuab: siv rau tshuab moulding
3. Thermoforming tshuab: siv rau thermoforming
4. tshuab luam ntawv: siv rau luam ntawv khob dej
5. Ntim tshuab: siv rau ntim thiab ntim cov khob dej
5. Cov lus xaus
Cov saum toj no yog cov txheej txheem tsim cov khob dej yas. Thaum lub sij hawm tsim khoom, nws tseem yuav tsum nruj me ntsis tswj cov kev sib txuas ntau lawm kom ntseeg tau cov khoom zoo thiab cov qauv kev tiv thaiv ib puag ncig. Nyob rau tib lub sijhawm, raws li tib neeg txoj kev paub txog kev tiv thaiv ib puag ncig tseem nce ntxiv, kev hloov pauv rau cov khob dej yas tau tshwm sim tas li. Kev txhim kho yav tom ntej ntawm kev lag luam khob dej kuj tseem tsim nyog tshawb nrhiav.
