Tshuab Moulding: Tshuab Moulding yog cov txheej txheem ceev, muaj txiaj ntsig zoo rau kev sib sau cov neeg tuav khoob ntawm cov thermoplastic polymers. Cov khoom tsim los siv lub voj voog no rau feem ntau muaj cov phab ntsa slim thiab ncav cuag qhov loj thiab cov duab los ntawm me me, extravagant jugs mus rau nws pib roj tso tsheb hlau luam. Nyob rau hauv lub voj voog no ib tug cylindrical zoo (parison) ua los ntawm ib tug sov so polymer yog nyob rau hauv lub qhov taub ntawm ib tug sib cais daim ntawv. Cua yog ces infused los ntawm ib rab koob mus rau hauv lub parison, uas extends mus kho rau lub xeev ntawm lub qhov. Cov txiaj ntsig ntawm kev sib sau ua ke suav nrog cov cuab yeej qis thiab ncaws cov nqi thoob, nrawm tsim tus nqi thiab lub peev xwm los tsim cov duab nyuaj hauv ib daim. Nws raug txwv, txawm li cas los xij, kom khoob lossis cylindrical duab.
Calendering: Calendering yog siv los tsim cov ntawv thermoplastic thiab cov yeeb yaj kiab thiab siv cov yas npog rau sab nraub qaum ntawm cov khoom sib txawv. Thermoplastics ntawm batter zoo li sib xws yog tsis pom zoo los ntawm thiab ib tug zuj zus ntawm warmed los yog txias yob. Nws cov txiaj ntsig suav nrog kev siv nyiaj tsawg thiab tias cov ntaub ntawv xa tawm tau yooj yim tso tawm los ntawm cov duab hauv kev ntxhov siab. Nws yog txwv tsis pub cov ntaub ntawv thiab cov yeeb yaj kiab me me tsis zoo.
Casting: Casting yog siv los xa cov nplooj ntawv, tuav, raj, kev seev cev ua ntej thiab kev teeb tsa nrog rau kev tiv thaiv hluav taws xob. Nws yog lub voj voog yooj yim, tsis tas yuav muaj lub zog sab nraud lossis nruj. Cov duab yog ntim nrog cov kua dej yas (acrylics, epoxies, polyesters, polypropylene, nylon lossis PVC tuaj yeem siv) thiab tom qab ntawd sov los kho, tom qab ntawd cov khoom siv los ua isotropic (muaj cov khoom zoo li no thiab qhov ntawd). Nws cov txiaj ntsig muaj xws li: tus nqi qis, lub peev xwm los tsim cov khoom loj nrog cov ntu tuab tuab, ua tiav qhov chaw zoo thiab nws txoj kev nplij siab rau cov khoom ntim qis. Tu siab, nws yog txwv tsis pub muaj cov duab ncaj nraim thiab nws nyiam ua rau tsis muaj nyiaj txiag ntawm kev tsim cov nqi siab.
Compression Moulding: Compression Molding yog siv qhov tseem ceeb rau kev tuav cov thermosetting polymers. Ib qho premeasured, feem ntau preformed nqi ntawm ib tug polymer yog encased nyob rau hauv ib tug kaw daim ntawv thiab raug rau siv thiab strain kom txog rau thaum nws yuav siv sij hawm lub xeev ntawm lub puab lub qhov thiab kho. Txawm hais tias lub sijhawm txheej txheem rau kev hloov pauv siab yog qhov tseem ceeb ntev dua li qhov kev sib sau ua ke thiab ntau qhov chaw los yog qhov tshwj xeeb ze rau kev tawm tsam yog qhov nyuaj rau xa, nws txaus siab rau ob peb yam txiaj ntsig suav nrog tus nqi qis hauv lub xeev (cov cuab yeej thiab khoom siv siv tau yooj yim dua thiab tsis tshua kim), cov khoom siv tsawg tsawg thiab qhov tseeb uas loj heev, cumbersome qhov chaw tuaj yeem ua tau zoo li tus thiab lub voj voog yog ntau yam kom ceev computerization.
Kev tshem tawm: Kev tshem tawm yog siv rau kev sib sau ua ke ntawm cov yeeb yaj kiab, ntawv, tubing, channels, funneling, tuav, cov ntsiab lus thiab filaments nrog rau cov profiles sib txawv thiab muaj feem xyuam rau tshuab shaping. Cov hmoov los yog granular thermoplastic los yog thermoset polymer yog saib xyuas los ntawm ib lub thawv rau hauv ib lub thawv sov uas nws yaj thiab xa mus, raws li txoj cai los ntawm ib tug pivoting ntsia hlau, los ntawm ib tug spout muaj qhov zoo tagnrho hla ntu. Nws yog txias nrog ib tug txaws ntawm dej thiab ces hlais mus rau qhov zoo tagnrho lengths. Lub voj voog raug tshem tawm yog inclined mus rau qhov pom ntawm nws cov nqi qis, lub peev xwm los tswj cov duab profile nyuaj, lub sijhawm ntawm kev tsim cov nqi nrawm thiab lub peev xwm ntawm kev siv cov coatings lossis tsho rau cov khoom siv hauv nruab nrab (xws li hlau). Nws yog txwv rau cov cheeb tsam ntawm cov khaubncaws sab nraud povtseg, ua li ntawd.
Txhaj Molding:Txhaj Moldingyog cov txheej txheem feem ntau koom nrog rau kev tsim khoom loj ntawm cov khoom yas vim nws qhov kev tsim cov nqi siab thiab cov lus txib zoo tshaj ntawm cov khoom 'yam. (El Wakil, 1998) Hauv lub tswv yim no, cov khoom siv polymer tau saib xyuas los ntawm lub thawv hauv pellet lossis hmoov txheej rau hauv chav uas nws tau sov so rau ntau yam. Tom qab ntawd nws raug txwv rau hauv qhov sib cais-daim kab noj hniav thiab solidifies nyob rau hauv nro, tom qab uas cov duab qhib thiab ib feem yog catapulted. Lub upsides ntawm infusion forming yog siab creation tus nqi, tsis tshua muaj nqi ua hauj lwm, siab reproducibility ntawm nyuaj subtleties thiab ib tug zoo nto tiav. Nws cov kev txwv yog siab pib apparatus thiab dhau ntawm cov nqi thiab txoj kev uas nws tsis yog nyiaj txiag ua haujlwm rau me ntsis khiav.
Rotational Moulding: Rotational Molding yog ib lub voj voog uas cov khoom khoob tuaj yeem tsim los ntawm cov khoom siv thermoplastics thiab lub sijhawm thermosets. Ib tug nqi ntawm cov muaj zog los yog kua polymer yog muab tso rau hauv ib tug zoo, uas yog warmed thaum nyob rau tib lub sij hawm tig ib ncig ntawm ob opposite tomahawks. Hauv qhov no, lub zog radial thawb lub polymer tawm tsam cov phab ntsa ntawm daim ntawv, framing ib txheej ntawm cov tuab tuab hloov mus rau lub xeev ntawm kab noj hniav thiab uas yog tom qab ntawd txias thiab catapulted los ntawm cov duab. Kev sib cuam tshuam dav dav muaj lub sijhawm ncua ntev ntawm lub voj voog tab sis nws txaus siab rau cov txiaj ntsig ntawm kev muab cov khoom siv tsis muaj kev txwv tsis pub dhau lub sijhawm thiab tso cai rau qhov nyuaj kom zoo li siv cov cuab yeej siv nyiaj tsawg thiab cov cuab yeej siv.
Thermoforming: Thermoforming suav nrog ntau lub voj voog uas siv los ua cov khoom siv hauv khob, piv txwv li, cov khoom sib txuas, cov laug cam, cov chaw nyob thiab cov tshuab saib xyuas los ntawm cov ntawv thermoplastic. Ib qho kev siv zog so ntawm cov ntawv thermoplastic yog nyob ntawm cov duab thiab cov huab cua yog emptied ntawm nruab nrab ntawm ob, constraining daim ntawv kom hloov mus rau hauv daim ntawv ntawm daim ntawv. Tom qab ntawd cov polymer yog txias kom nws yuav tuav nws cov duab, tshem tawm ntawm daim ntawv thiab lub web encompassing nws yog tswj. Lub upsides ntawm thermoforming muaj xws li: tus nqi qis tooling, lub sij hawm ntawm enormous feem creation nrog meager cheeb tsam thiab hais tias nws yog nquag ceev faj rau txwv ib feem creation. Txawm li cas los xij, nws yog txwv tsis pub nyob rau hauv qhov chaw yuav tsum yog kev teeb tsa ncaj nraim, muaj cov khoom siv siab, muaj ob peb yam khoom siv uas tuaj yeem siv nrog lub voj voog no, thiab lub xeev ntawm cov khoom tsis tuaj yeem muaj qhov qhib.
