Qhov txawv ntawm pwm thiab molding yog dab tsi?
Pwm thiab molding yog ob lo lus siv ntau hauv kev tsim khoom thiab feem ntau siv sib hloov. Txawm li cas los xij, muaj qhov sib txawv tseem ceeb ntawm ob. Kab lus no yuav tshawb txog qhov sib txawv no kom ntxaws los pab qhia meej lawv qhov txawv.
Lub ntsiab lus ntawm Pwm thiab Moulding
Lub pwm yog lub thawv hollow uas siv los ua cov khoom molten lossis cov khoom zoo sib xws rau hauv cov duab uas xav tau. Nws yog ib yam ntawm cov cuab yeej uas tsim ib qho kev tshwj xeeb rau cov khoom koj tab tom ua haujlwm nrog. Lub sij hawm pwm tuaj yeem xa mus rau ob lub thawv nws tus kheej thiab cov khoom zoo li tshem tawm ntawm nws.
Moulding, ntawm qhov tod tes, yog txheej txheem ntawm kev tsim cov khoom siv los ntawm kev siv lub siab los ntawm sab nraud. Nws koom nrog kev pub cov khoom siv rau hauv lub tshuab uas compresses nws nyob rau hauv siab thiab ua rau nws nyob rau hauv cov duab uas xav tau. Feem ntau, moldings yog tsim los ntawm cov khoom xws li ntoo, hlau, los yog yas.
Hom Pwm
Pwm tuaj nyob rau hauv ntau hom, nyob ntawm seb cov khoom uas lawv tau siv rau. Qee yam ntawm cov pwm feem ntau muaj xws li:
1. Txhaj Moulds: Txhaj pwm yog siv rau hauv kev tsim cov khoom yas. Lawv muaj ob feem pwm uas yog clamped ua ke los ua ib tug hollow kab noj hniav. Molten yas yog txhaj rau hauv kab noj hniav, uas yog tom qab ntawd tso cai rau txias thiab khov. Thaum cov yas tau teem, pwm qhib, thiab qhov txhaj tshuaj molded raug tshem tawm.
2. Tshuab Moulds: Tshuab tshuab yog siv los tsim cov khoom hollow xws li lub raj mis, tank, thiab ntim. Lawv muaj cov kab noj hniav pwm thiab parison, ib lub raj zoo li cov khoom yas uas yog extruded rau hauv pwm. Thaum lub parison nyob rau hauv pwm, nws yog inflated nrog huab cua, ua rau cov yas ua raws li cov duab ntawm cov kab noj hniav. Thaum cov yas tau txias thiab khov kho, cov pwm qhib, thiab cov khoom raug tshem tawm.
3. Rotational Pwm: Rotational Moulds yog siv los tsim cov khoom loj, hollow xws li kayaks, cov khoom siv hauv chaw ua si, thiab lub tank cia. Cov txheej txheem yuav tsum tig ib lub pwm nyob ib ncig ntawm ob lub voj voog perpendicular thaum cua sov nws. Cov khoom siv yas hmoov yog muab tso rau hauv pwm, thiab cua sov ua rau nws yaj thiab coated rau hauv pwm. Thaum cov yas tau txias thiab khov kho, cov pwm qhib, thiab cov khoom raug tshem tawm.
Hom Moulding
Zoo li cov pwm, molding kuj tuaj ntau hom, nyob ntawm cov khoom siv thiab cov txiaj ntsig xav tau. Qee yam ntawm ntau hom molding muaj xws li:
1. Crown Moulding: yas molding yog siv los ua cov khoom siv kho kom zoo nkauj hauv kev tsim sab hauv kom muab chav ua kom tiav. Nws feem ntau yog ua los ntawm ntoo thiab yog siv los cap qhov sib txuas ntawm lub qab nthab thiab phab ntsa.
2. Baseboard Moulding: Baseboard molding yog siv los npog qhov sib koom ntawm hauv pem teb thiab phab ntsa hauv ib chav. Nws kuj yog tsim los ntawm cov ntoo thiab tuaj yeem ua cov khoom siv kho kom zoo nkauj hauv tsev tsim tag nrho.
3. Qhov rai thiab qhov rooj casing: Qhov rai thiab qhov rooj casing yog siv los thav duab qhov rais thiab qhov rooj thiab muab ib tug tiav saib rau qhov qhib nyob rau hauv ib chav tsev. Nws feem ntau yog tsim los ntawm cov ntoo lossis cov khoom siv zoo sib xws thiab tuaj yeem tuaj yeem ua ntau hom thiab ntau thiab tsawg.
Kev siv Pwm thiab Moulding
Ob leeg pwm thiab molding muaj ntau yam kev siv hauv kev tsim thiab kev tsim kho.
Pwm feem ntau yog siv los tsim cov khoom yas, iav, thiab hlau. Lawv yog ib qho tseem ceeb ntawm cov txheej txheem tsim txhua yam los ntawm cov khoom ua si thiab cov khoom siv hauv tsheb mus rau cov xov tooj thiab cov khoom siv kho mob.
Moulding feem ntau yog siv rau hauv kev tsim kho los tsim kom muaj kev ua tiav ntau dua rau chav lossis lub tsev. Nws tuaj yeem siv los ntxiv cov hniav kov rau phab ntsa, qhov rooj, thiab qhov rais.
Xaus
Hauv cov ntsiab lus, muaj qhov sib txawv tseem ceeb ntawm pwm thiab molding. Thaum cov pwm yog siv los ua cov ntaub ntawv xws li yas, iav, thiab hlau, molding yuav tsum shaping cov ntaub ntawv xws li ntoo, hlau, los yog yas los ntawm kev thov los ntawm sab nraud.
Kev nkag siab txog qhov sib txawv ntawm ob yog qhov tseem ceeb, tshwj xeeb tshaj yog tias koj ua haujlwm hauv kev tsim khoom lossis kev tsim kho kev lag luam. Los ntawm kev paub txog lawv cov yam ntxwv tshwj xeeb, koj tuaj yeem xaiv cov cuab yeej tsim nyog tshaj plaws lossis cov txheej txheem kom ua tiav koj qhov kev xav tau thiab tsim cov khoom zoo.
