Txhua tus kws ua haujlwm uas tau saib ntau lub-kab kab noj hniav tawm ntawm spec paub tias qhov nyuaj ntawm extrusion tsis thawb yas los ntawm lub qhov. Nws yog tswj qhov tshwm simsab hauvlub void, thiab hauv qhov khoob uas koj tsis tuaj yeem pom thaum kab khiav. Qhov kab noj hniav yog tag nrho cov teeb meem nyob rau hauv hollow profile extrusion: nws yog dab tsi cais ib lub raj los yog multi-lumen seem los ntawm ib tug pas nrig, thiab nws yog qhov twg txhua qhov nyuaj kam rau ua thiab txhua lub teb tsis ua hauj lwm pib.Qhov no yog ib tug ua hauj lwm qhia yuav ua li cas hollow seem yog tsim, dab tsi phab ntsa thiab kam rau ua koj muaj peev xwm tuav, qhov twg tus txheej txheem tsis ua hauj lwm, thiab yuav ua li cas los qhia rau ib tug muaj peev xwm.
Qhov Void Ua li cas rau Physics
Nyob rau hauv cov khoom profile extrusion tus tuag ua ib txoj hauj lwm: zoo li tus ntoo khaub lig txuas ntxiv -section raws li cov yaj tawm hauv lub thoob. Qhia ib kab noj hniav thiab tag nrho cov teeb meem ntws hloov. Ib tus pin lossis mandrel tam sim no zaumsab hauvqhov tuag, cov molten polymer yuav tsum tau sib cais, ntws nyob ib ncig ntawm nws, thiab knit rov qab ua ke downstream. Cov kab ntawd, cov seam weld, yog ib qho feem ntau nyob rau hauv - tham txog qhov tsis muaj zog nyob rau hauv hollow yas profile extrusion, vim hais tias nws yog ib cheeb tsam uas ob melt fronts rejoin nyob rau hauv tsawg dua - dua - zoo tagnrho siab thiab kub, thiab nws yeej tsis heev muaj zog ntawm cov phab ntsa nyob ib ncig ntawm.
Lub void tsim teeb meem thib ob. Lub mandrel yuav tsum tuav txoj hauj lwm thaum lub viscous yaj ntawm ob peb puas bar thawb tawm tsam nws, thiab txhua qhov deflection ntawm tus pin qhia ncaj qha li cov phab ntsa tsis sib xws. Yog li ua ntej leej twg hais txog kev zam txim, nkag siab txog qhov kev txwv tiag tiag: ib qho hollow seem tsuas yog zoo li qhov kev ruaj ntseg ntawm lub mandrel - thiab - tuag teeb tsim nws sab hauv. Yog tias koj tab tom pib los ntawm lub hauv paus ntawm yuav ua li cas thermoplastic melted thiab zoo li tus, peb lub ntsiab lus ntawmyas extrusion yog dab tsinpog cov hauv paus hauv paus; ntawm no peb nyob ntawm qhov hollow - tshwj xeeb tsis ua hauj lwm nto.
Cov Txheej Txheem Yas Tube Extrusion, Chaw Nres Tsheb los ntawm Chaw Nres Tsheb: Yuav Ua Li Cas Txhua Qhov Kev Txiav Txim Siab Tom ntej
Txhua qhov chaw nres tsheb txwv tsis pub dhau mus, thiab qhov kev xa tawm ntxov uas mus tsis raug yog ib qho tsis muaj kev kho qis qis rov qab los.Pellets yaj thiab homogenize hauv lub extruder, tom qab ntawd cov yaj nkag mus rau hauv lub taub hau lossis hauv - kab tuag qhov twg mandrel tsim cov bore. Lub cev zoo li, tseem - lub raj molten tawm mus rau hauv lub tshuab nqus tsev sizing tank, qhov twg lub tes tsho calibration thiab tswj lub tshuab nqus tsev rub lub phab ntsa sab nraud tawm tsam ib txoj kab uas hla thaum lub polymer tseem mos txaus los teeb tsa nws qhov kawg OD. Txias raws li nram no, ib feem yog ntsuas hauv - kab, ces khij thiab txiav kom ntev. Qhov sib piv -down ratio, ntau npaum li cas cov yaj yog stretched ntawm tuag thiab sizing, yog ib tug ntawm cov ntsiag to levers nyob rau hauv kawg phab ntsa. Tib kab geometry kuj txhawb nqa ib co-extrusion hollow profile, qhov thib ob extruder nteg ib qho txawv resin mus rau hauv lub bore los yog daim tawv nqaij: ib tug barrier puab txheej, hais, los yog ib tug regrind core nyob rau hauv ib tug nkauj xwb daim tawv nqaij, tsis hloov li cas cov kab noj hniav yog tsim.
Ib daim ntawv uas piav qhia txog ntau yam kev xaiv khoom: siab- cov yeeb nkab thiab cov kab yeeb nkab tawm ntswj hnyav rau ntawm ib qho - ntsia hlau extruders, tseem yog lub tshuab ua haujlwm rau cov yeeb nkab thermoplastic thiab zaj duab xis yooj yim vim lawv yooj yim dua, pheej yig dua rau kev khiav, thiab lub zog- ua haujlwm zoo ntawm cov ntaub ntawv sib xws, txawm tias ntxaib - cov khoom sib xyaw ua ke sai dua -screw (Mordor Intelligence).Yog vim li cas lub khw optimized rau nruam tubing feem ntau tsis yog tib lub khw optimized rau hnyav hnyav compound. Rau cov geometry-thiab- resin tawg ntawm yuav ua li cas lub raj txuas txuas ua tau zoo, peb daim ntawmyuav ua li cas yas raj extrusion ua hollow khoommus chaw nres tsheb los ntawm chaw nres tsheb. Txhua qhov chaw nres tsheb hauv qab tsuas tuaj yeem ua haujlwm nrog dab tsi yav dhau los muab rau nws: bore zoo yog txiav txim siab ntawm qhov tuag, tsis yog lub tank loj.
Vim li cas Concentricity, Tsis Diameter, Predicts Hollow Extrusion Performance
Ntawm no yog tus ntxiab feem ntau kos duab poob rau hauv. Ob lub raj tuaj yeem sib koom ib txoj kab uas hla zoo tib yam thiab tseem muaj cov phab ntsa sib txawv kiag li, ib qho nruab nrab, ib qho nrog lub bore raug thawb tawm mus rau ib sab. Lub OD callout qhia koj tsis muaj dab tsi txog qhov ntawd. Concentricity ua, thiab nws yog concentricity, tsis yog txoj kab uas hla, uas txiav txim siab seb lub siab lub raj tsis tau thaum ntxov los yog ib tug catheter khoov raws li nws yuav tsum tau.
Qhov no kuj yog qhov uas concentricity thiab phab ntsa -thickness kam rau ua nyob rau hauv raj extrusion pib sib ntaus sib tua ntawm daim duab. Yog tias cov ntawv luam tawm ntawm nws tus kheej qhov ntev OD kam rau ua, phab ntsa kam rau ua, thiab concentricity, cov kev tswj peb sib tsoo: lub coaxiality ntawm sab hauv thiab sab nrauv twb tswj tau li cas phab ntsa tuaj yeem sib txawv ntawm OD, yog li stacking ib phab ntsa cais rau sab saum toj feem ntau dhau - txwv ib feem rau hauv ib yam dab tsi tsis muaj txheej txheem tuaj yeem cuam tshuam kev lag luam. Qhov ntawd yog qhov sib txawv ntawm cov neeg muag khoom feem ntau yuav tsis nce thaum lub sijhawm hais, thiab nws yog qhov zoo tshaj plaws DFM tshuaj xyuas tiag tiag ua ntej cov cuab yeej raug txiav, tsis yog tom qab thawj qhov kev ua haujlwm tsis nco qab.
Ntawm kev ntsuas: cov lus teb yuav ua li cas koj txawm paub tias phab ntsa tseem nyob hauv - kab ntsuas. Ntawm cov kab kho mob precision, cov hlab tawm ntawm extruder feem ntau dhau los ntawm ib lub nplhaib ntawm plaub lossis yim ultrasonic transducers thaum lawv nkag mus rau hauv lub tank quench, thiab inline ultrasonic systems qauv ntawm qhov kev txiav txim ntawm 2,000 ntsuas ib ob ib ncig ntawm lub voj voog (GaugeAdvisor).Me me - tho tubing tshwj xeeb tshaj yog nyob los yog tuag los ntawm qhov zoo li ntawd array nyob nruab nrab. Spot- tshawb xyuas cov qauv txiav ntawm qhov kawg qhia koj seb ib daim ntawv zoo li cas; nws tsis qhia koj lub phab ntsa tuav rau tag nrho cov spool.
Txoj Kev Tolerances Koj tuaj yeem tuav tau
Tus lej, vim qhov kev lees paub tsis meej tsis pab tsis muaj leej twg. Ntawm kev kho mob- qib ntau- lumen tubing, sab nraud - txoj kab uas hla tswj nyob ib ncig ntawm ± 0.025 mm yog ua tiav, nrog txhua lub lumen tuav los ntawm nws tus kheej mandrel tus pin thiab nws tus kheej ntawm nws tus kheej tswj huab cua siab. Qhov ntawd rau - lumen siab tswj yog dab tsi ua rau ib qho channel tsis txhob sib tsoo thaum lwm qhov nyob ib puag ncig. Peb kho cov duab no raws li cov lus qhia muaj peev xwm los ntawm peb tus kheej cov kab, tsis yog daim ntawv teev npe, thiab qhov tseeb caveat yog tias nws yog geometry- thiab resin-dependent: nyias-phab ntsa, siab-modulus resin nyob rau hauv ib qho yooj yim puag ncig tuav deb nruj tshaj li ib tug mos, multi{12}}cavity
Tus nqi sib cav tom qab tuav lub siab ntev no nruj ntawm ntau -lumen tubing khiav rov qab rau qhov kev xav. Ib tus kheej -qhov nruab nrab tuag nrog kaw- voj phab ntsa tswj tsis yog tsuas yog txhim kho zoo - los ntawm kev ua kom zoo ntawm phab ntsa thiab concentricity tsis hais cov kab ceev, nws nqaim phab ntsa- thickness kam rau ua band li 0.05 hli thiab txiav cov khoom siv los ntawm kwv yees li 2.5% (KraussMaffei). Ntawm kab khiav 24/7, cov ntaub ntawv khaws cia ib leeg tuaj yeem them rov qab cov cuab yeej zoo dua hauv lub lis piam. Tab sis qhov ntawd 2.5% yog cov cuab yeej tsim cov duab raws li kev tsim tawm tas mus li ntawm cov kab uas hla tshwj xeeb - qhov koj qhov ua tau txuag yog nyob ntawm tus nqi resin, kab ceev, thiab qhov nyuaj ntawm tus ntoo khaub lig -section yog li cas, thiab cov lej them rov qab tsuas yog tau txais tiag tiag thaum cov nyob ntawm lub rooj. Lub ntsiab lus tsis yog lub gadget; nws yog qhov kev tswj xyuas nruj dua thiab tus nqi qis dua yog tib lub peev, tsis yog kev lag luam tawm - uas yog ib feem ntawm daim ntawv teev lus tsis tau qhia.
Qhov twg Hollow Extrusion Tiag mus yuam kev
Cov kab hauv qab rau pem hauv ntej: pob txha tawg thiab phab ntsa yog shear- thiab - cov teeb meem cuam tshuam, tsis yog cov ntsiab lus koj tuaj yeem hu tau yooj yim, uas yog vim li cas cov kev kho muaj kev txiav txim.
Cov kws ua haujlwm tsis raug cai ntshai feem ntau txhua tus nyob ntawm qhov tuag tawm thiab txhua tus muaj qhov tshwj xeeb, kuaj pom qhov ua rau. Sharkskin yog ib qho ntxhib, scaly nto: nto yaj tawg los ntawm ntau shear ntawm cov av tuag raws li cov polymer cov tawv nqaij plam thiab rub tawm ntawm qhov tuag. Push yaj nrawm dua thiab nws degrades mus rau tag nrho cov tawg tawg, qhov twg tag nrho extrudate distorts. Tuag drool yog gummy buildup uas accumulates ntawm daim di ncauj thiab periodically streaks ib feem; kab tuag los ntawm kev kis kab mob lossis kev puas tsuaj hauv thaj av tuag; tuag swell, lub extrudate expanding yav tas los tuag dimension raws li cov polymer relaxes, yog dab tsi rog sizing kom muaj nyob rau hauv tag nrho cov.
Muaj qhov tsis sib haum xeeb tiag tiag tsim nyog tsa, vim tias phau ntawv sau ntawv tsis tiav. Cov kab ntau yog tias sharkskin yog ib qho txheej txheem pob qhov rooj: poob tus nqi shear lossis nce qhov kub thiab nws mus. Cov kev tshawb fawb tsis pom zoo nyob rau hauv ib txoj kev uas tseem ceeb rau cov cuab yeej: cov kev tshawb fawb tau pom cov khoom siv ntawm cov av tuag nws tus kheej cuam tshuam rau cov pob txha tawg hauv LLDPE, tsis zoo li cas capillary -rheometer ntsuas kwv yees, taw tes rau polymer- rau- hlau adhesion tsis ua hauj lwm ntawm lub interface raws li tus neeg tsav tsheb tiag tiag, tsis yog tsuas yog bulk flow (ResearchGate). Yog li yog tias koj tau ua kom zoo rau qhov kub thiab txias thiab tseem sib ntaus sib tua tawg, cov khoom siv tuag thiab av geometry yog nyob rau ntawm lub rooj.
Ntawm no yog yuav ua li cas uas yeej plays tawm ntawm ib kab. Ntawm qhov nruj-PVC profile khiav ob peb xyoos rov qab peb tau caum tus qauv sharkskin uas yuav tsis tshem ntawm qhov kub thiab txias ib leeg - peb nqa cov tuag- av kub txog li 8℃thiab tau txais kev txhim kho ib nrab, tom qab ntawd dosed nyob rau hauv thaj tsam ntawm 600 ppm ntawm ib tug fluoropolymer processing ib leeg, thiab poob rau hauv ib tug fluoropolymer processing aid, thiab tib lub sijhawm. Cov kab ke ntawd yog txoj cai ntawm tus ntiv tes xoo peb khiav los ntawm: sim ntsuas kub thiab txiav ua ntej, nqa cov khoom siv polymer ua haujlwm ntawm 200-2,000 ppm yog tias cov khw muag khoom, thiab tsuas yog qhib qhov tuag- khoom sib tham thaum ob qho tib si ua tsis tiav. Dimensional instability tshaj ib tug khiav yog yuav luag ib txwm phab ntsa drift, uas yog raws nraim yog vim li cas nyob rau hauv - kab ntsuas voj los ntawm lub yav dhau los seem yuav tsum kaw rov qab mus rau tuag, tsis yog lub tswb.
Yas vs. Aluminium: Ib lub rooj, vim cov neeg yuav khoom tiag tiag xaiv ntawm lawv
Cov kev taw qhia feem ntau xaiv ib txoj kab thiab tsis txhob muab cov yas thiab hlau ib sab, txawm tias qhov ntawd yog qhov kev txiav txim siab tiag tiag ntawm ntau cov kev pab cuam. Cov mechanisms yeej sib txawv. Hollow profile extrusion nyob rau hauv aluminium splits lub billet los ntawm ib tug porthole los yog choj tuag thiab re-welds nws nyob ib ncig ntawm lub mandrel, uas yog vim li cas aluminium hollow seem nqa structural seam welds thiab yog vim li cas khawb - lub taub hau ntev ntawm qhov kev txiav txim ntawm 500-1,000 mm raug txiav tawm ntawm startup kom tshem tawm qaug zog weld zones. Yas tuav nws cov kab noj hniav sib txawv: ib lub zog los yog nqus dej -fed cua txoj hauv kev los ntawm mandrel ua rau lub bore tsis txhob sib tsoo los ntawm qhov loj me thiab txias.

| Zoo tshaj plaws | Tight- txoj kev kam rau ua kua, dielectric qhov chaw, complex multi-lumen | Load-cov qauv bearing, tshav kub dissipation, rigidity |
Qhov kev txiav txim, tsis yog ib tug shrug: rau ib tug multi- kab noj hniav kua los yog wiring channel qhov twg per - kab noj hniav kam rau ua thiab tshuaj inertness tsav lub spec, yas hollow extrusion yeej no outright - txhuas tsis tau ntawm nws tus kheej tswj peb lub me me bores.Rau ib tug structural tswv cuab nqa mechanicalgen qhov twg cov phab ntsa yuav tsum tau. teb, thiab yuam yas yog yuam kev. Cov ntaub ntawv nruab nrab, ib qho nruj, qhov ntev ruaj khov channel uas tseem yuav tsum tau ua ib qho insulator, yog qhov uas nruj PVC lossis PC tiag tiag sib tw nrog txhuas, thiab qhov kev txiav txim siab ntawm cov khoom yuav tsum tau ua ntawm tus nqi -ib - meter thiab kev sib dhos, tsis yog ntawm reflex. Qhov twg raws nraim tus nqi -ib -meter crossover ntog yog nyob ntawm kab noj hniav, phab ntsa spec, thiab khiav ntev, thiab pinning down rau ib feem yog thawj yam uas peb ua hauj lwm tawm nyob rau hauv DFM tshuaj xyuas ua ntej leej twg yuav tuag.
Xaiv cov Resin, thiab Recycled -Cov ntsiab lus Trap
Resin ua raws li daim ntawv thov, tsis nyiam. Rigid PVC dominates lub tsev thiab tso dej thiab tso nyiaj rau ib feem loj ntawm tag nrho cov PVC resin noj; PE thiab PP nqa cov kab siab thiab tshuaj lom neeg; PC thiab ABS qhia txog qhov cuam tshuam lub zog, pom tseeb, lossis tus cwj pwm dielectric teeb meem. Rau feem ntau cov kev cai yas tubing cov ntaub ntawv txiav txim siab cov resin yog teem los ntawm kev pab cuam, kev ntsuam xyuas siab, kub, dab tsi dej kov lub bore, ntev ua ntej aesthetics nkag. Cov yeeb nkab yas xav tau loj hlob nyob rau hauv nruab nrab -ib zaug- lej- feem pua ntau xyoo, nrog Asia-Pacific ua ntim thiab PVC / PE ua cov khoom ua haujlwm (Grand View Research), uas feem ntau tseem ceeb ntawm no raws li kev ceeb toom tias cov khoom siv cob thiab cov cuab yeej muaj raws li cov ntim ntawd.
Tam sim no cov ntxiab buyers poob rau hauv feem ntau. Lub suab "peb siv cov ntsiab lus rov ua dua kom txuag nqi" suab lub luag haujlwm thiab nquag yog - tab sis tsuas yog nyob rau hauv ib qho xwm txheej xwb. Tswj tau, ib zaug - khoom siv hauv - cog regrind, sib xyaw ntawm qhov kev tswj hwm, yog siv tau thiab peb khiav nws.
