Ntau thiab ntau dua processors xav tau ntau dua precision nyob rau hauv lawv cov khoom noj.Nov yog qee cov neeg ua.# Cov txheej txheem qhia
Lub Plastrac gravity disc feeder tau hloov kho kom khiav ntawm ntsug txhaj tshuaj molding tshuab siv los ntawm Weiss-Aug Surgical Products 'kev txhaj tshuaj molding division.
Preform Solutions feem ntau tshwj xeeb hauv kev txhaj tshuaj molding kev cai preforms nyob rau hauv ntau yam xim, tab sis ntawm no nws siv Plastrac feeders los xyuas kom meej dosing raug thiab ceev changeovers ntawm nws stretch tshuab molding kab.
Movacolor's MCNexus tam sim no tab tom raug sim rau cov neeg siv khoom tom qab muag muag ntawm K 2016;Lub feeder qis qis yuav ua nws qhov kev lag luam debut ntawm Fakuma thaum Lub Kaum Hli.
Txhawm rau zam kev siv cov khoom sib xyaw ua ntej, cov txheej txheem hauv qee lub lag luam tau nce ntxiv thov lawv cov khoom siv tuav cov khoom lag luam kom muab kev pub noj ntau dua - nqis mus rau cov gram ntawm ib tus neeg granules thiab additives - piv txwv li, siv ib qho zas xim uas poob tawm yog qhov sib txawv. nruab nrab ntawm qhov zoo thiab qhov tsis tsim nyog.Roger Hultquist tham txog kev ua haujlwm kho mob tsis ntev los no los piav qhia nws cov ntsiab lus.Cov neeg siv khoom hauv nqe lus nug xav kom raug pub peb lub cylindrical dye pellets rau hauv lub tshuab txhaj tshuaj molding qhov chaw pub noj nyob rau hauv lub sijhawm rov qab los ntawm kwv yees li 3 vib nas this.
"Nws tsis zoo li kev pub mis ntawm 100 phaus ib teev," hais tias Hultquist, co-founder thiab tus thawj tswj hwm ntawm kev muag khoom thiab kev lag luam ntawm Orbetron, tus neeg muab khoom noj, sib tov thiab cov khoom siv tuav hauv Hudson, Wisconsin.Ib qho kev txhaj tshuaj, ib qho tuaj yeem ua rau muaj qhov sib txawv loj hauv qhov tseeb, uas tau dhau los ua qhov teeb meem loj dua, tshwj xeeb tshaj yog nyob rau hauv kev siv kho mob thiab tshwj xeeb tshaj yog nyob rau hauv kev tsim cov khoom translucent.“
Nyob rau hauv luv luv, raws li feedrate yuav tsum tau txo, yog li ua kom raug.Orbetron, uas tshwj xeeb hauv cov kav dej qis qis, tau hloov kho cov hmoov pub mis thaum chiv thawj siv hauv kev lag luam tshuaj rau cov yas.(Saib Lub Xya Hli 2017 Hultquist tsab xov xwm: Nkag siab Tus Nqi Qis Pub Rau Kev Nruam thiab Cov Txheej Txheem Ua Haujlwm.)
Ntau tus neeg muag khoom siv lub hom phiaj ntawm kev ua lag luam niche ntawm cov txheej txheem uas siv qhov kev ua tau zoo thiab hloov tau yooj yim ntawm cov khoom siv qis qis kom sib xyaw cov ntaub ntawv hauv cov tshuab thiab lwm yam kev siv uas yuav tsum muaj qhov siab tshaj plaws.
Rau cov txheej txheem ntxiv cov khoom ntxiv ntawm tus nqi ntawm 0.5 lb mus rau 1 lb ib teev, qhov tseeb siab tsis yog qhov tseem ceeb, tab sis raws li tus nqi no txo ​​qis, qhov tseeb yog qhov tseem ceeb."Nyob rau hauv ib txoj haujlwm xaim thiab cable uas koj pub khoom noj ntawm 15 g / h, nws tseem ceeb heev kom tau txais cov khoom no raws nraim qhov lawv yuav tsum mus," Hultquist tau hais."Thaum tus nqi qis, qhov no dhau los ua qhov tseem ceeb, tshwj xeeb tshaj yog thaum nws los txog rau xim - xim sib xws ntawm cov khoom no yog ib qho ntawm peb tsom mus rau."extruder caj pas, pab daws qhov Hultqvist hais tias yog ob txoj kev teeb meem rau pellets.
"Koj tuaj yeem ua haujlwm rau nws, tab sis ib zaug nws tau txais kev pabcuam, tam sim no koj yuav tsum paub tseeb tias nws tau muab faib rau hauv koj cov txheej txheem," Hultquist piav qhia.
Hultqvist tau sau tseg tias ntxiv rau qhov raug, cov neeg ua si hauv thaj chaw no kuj xav tau kev hloov pauv siab."Rau lub khw pwm kev cai uas hloov xim sai, tej zaum 10, 12, 15 zaug hauv ib hnub, nws tseem ceeb heev uas lawv tuaj yeem nres thiab hloov xim hauv ob peb feeb."yog rub tawm ntawm lub cuab yeej, tso cai rau cov txheej txheem hloov ntawm ib qho khoom noj mus rau lwm qhov raws li cov xim hloov.
Orbetron tam sim no muaj cov khoom noj hauv plaub qhov ntau thiab tsawg - 50, 100, 150 thiab 200 series - nrog lub peev xwm ntawm 1 gram / hr txog 800 lb / hr.Ntxiv nrog rau kev pleev xim rau hauv kev lag luam xws li hlau / cable thiab cov khoom siv kho mob, Hultqvist tau sau tseg, lub tuam txhab tau nthuav dav rau hauv kev lag luam cov ntaub ntawv hauv tsev, qhov twg disc feeders yog siv los pub tshuab tshuab, cov xim dyes, profiles thiab panels, cov neeg ua hauj lwm thiab lwm yam additives. ..
Kev hloov pauv sai yog "peb qhov kev pom zoo," piav qhia Jason Christopherson, tus thawj coj ntawm Preform Solutions Inc., nyob hauv Sioux Falls, South Dakota.Kev daws rau luv luv thiab nruab nrab khiav ntawm pwm nrog 16 thiab 32 kab noj hniav.Qhov no zam qhov ntim loj loj uas cuam tshuam nrog cov dej los yog cov dej haus lub raj mis preforms, uas tuaj yeem siab li 144 lossis ntau dua.
Kristofferson hais tias "Ntau ntawm peb txoj haujlwm siv dyes."Txhua hnub ntawm lub lim tiam peb tuaj yeem muaj ob, peb, plaub kab nrog cov xim sib txawv thiab cov khoom sib txawv rau peb cov preforms."
Tag nrho cov ntxoov ntxoo no yuav tsum tau muab cov xim pleev xim kom raug, thiab lub tuam txhab lub hom phiaj tau txais ntau dua, mus txog 0.055% ntawm 672g thiab 0.20% ntawm 54g (qhov kawg yog 98.8% resin thiab 0.2%).% xim).Preform Solutions tau ua lag luam txij li xyoo 2002 thiab rau feem ntau ntawm lub sijhawm ntawd, lawv qhov kev hloov pauv ceev ceev pub noj tshuaj yog qhov Gravity Auto-Disc Feeder los ntawm Plastrac, Inc. los ntawm Edgemont, Pennsylvania.Lub tuam txhab tam sim no muaj 11 Plastrac units nrog plaub ntxiv ntawm kev txiav txim.
Qhov zoo ntawm Preform Solutions raws li Plasrac thev naus laus zis yog qhov tsim tshwj xeeb thiab nws cuam tshuam rau qhov raug.Lub feeder siv cov hniav, qhov tseem ceeb yog dosing granules los ntawm kev txiav.Lub feeder tso cov pellets rau hauv hnab ris ntawm lub disc thiab cov hniav scrapes tawm ib feem ntawm cov pellets uas txuas dhau lub hnab ris.Christofferson tau hais tias "Thaum lub cuab yeej Plastrac txiav los ntawm cov nplej thiab smooths tawm lub hnab tshos qhov twg cov khoom nkag mus rau hauv cov hniav, nws yog qhov tseeb heev," Christofferson hais.
Plastrac feeders kuj pom tau siv hauv kev lag luam cuam tshuam nrog Weiss-Aug Surgical Products hauv Fairfield, NJ.Raws li Elisabeth Weissenrieder-Bennis, tus thawj coj ntawm kev npaj tswv yim, feem ntau yog me me, feem ntau 1 txog 2 lossis tsawg dua.
Raws li Leo Czekalsky, tus thawj coj molding, 12 Weiss-Aug Plastrac units tau tshwj xeeb hloov los ntawm Plastrac los ua haujlwm ntawm Arburg lub ntsug txhaj tshuaj molding tshuab.Plasrac units muab cov cav tov nrog qhov ntau thiab tsawg ntawm 2 mus rau 6 ooj thiab auger diameters los ntawm 16 mus rau 18 mm.Chekalsky tau hais tias "Qhov ntau thiab tsawg ntawm kev txhaj tshuaj uas peb yuav tsum tau khaws cia rau cov khoom no yog nyob rau hauv ntau txhiab ntawm ib nti," Chekalsky tau hais."Thiab txij li kev rov ua dua thiab ntim ntim yog qhov tseem ceeb, tsis muaj chaw rau kev hloov pauv."
Raws li Chekalsky, qhov no repeatability txuas mus rau cov xim muab los ntawm Plastrac.Chekalsky tau hais tias "Kuv tsis tau pom dab tsi yog qhov tseeb thiab ntseeg tau ntau dua li cov cuab yeej no,""Muaj ntau lub tshuab xav kom ib tus neeg los ntsuas thiab kho thaum hloov cov duab lossis xim, tab sis ntawm no lub kaw lus tsis xav tau dab tsi."
Weiss-Aug txaus siab rau qhov raug thiab ua haujlwm tsis muaj teeb meem, tshwj xeeb tshaj yog muab lub khw uas ua haujlwm rau Fairfield.Weissenrieder-Bennis tau hais tias "Cov khoom no muaj tus qauv pom zoo vim tias lawv tau siv hauv kev phais," Weissenrieder-Bennis."Muaj cov qauv xim tshwj xeeb thiab koj yeej tsis tuaj yeem muaj qhov txawv txav."
Ntawm K 2016, Dutch tuam txhab Movacolor BV (muab faib rau hauv Teb Chaws Asmeskas los ntawm ROMAX, INC. ntawm Hudson, Massachusetts) tau qhia nws tus kheej tsis pub noj tshuab, MCNexus, uas nws hais tias tuaj yeem pub 1 txog 5 qhov (saib K qhia qhia rau Lub Ob Hlis 2017) .).
Ib tus neeg hais xov xwm Movacolor tau hais tias MCNexus tam sim no tab tom raug sim los ntawm ntau tus neeg siv khoom hauv Tebchaws Europe uas siv nws kom raug faib cov xim me me hauv cov khoom ua si thiab cov khoom siv hauv tsev.Movacolor yuav nthuav tawm MCNexus ntawm Fakuma 2017 hauv Friedrichshafen, Lub Tebchaws Yelemees thaum Lub Kaum Hli, kuj tseem kos npe rau nws qhov kev tshaj tawm kev lag luam.
Feem ntau cov pwm siv ob qhov chaw los teeb tsa lub siab thib ob.Tab sis Scientific Moulding yeej muaj plaub.
Nrog rau kev zam ntawm polyolefins, yuav luag tag nrho lwm cov polymers yog polar rau qee qhov kev kawm thiab yog li tuaj yeem nqus tau qee qhov dej ntawm qhov chaw.Nov yog qee cov ntaub ntawv no thiab koj yuav tsum ua dab tsi kom qhuav lawv.
