PET Preform pwm

PET preform pwm txais yuav ib rab koob valve kub khiav system. Thaum lub sij hawm PET txhaj tshuaj molding txheej txheem, rab koob valve kub khiav siv txhua yam kev txiav txim kaw thiab qhib lub qhov rooj txhaj tshuaj ntawm txhua kab noj hniav. Cov khoom ntawm lub rooj vag kab tsuas yog sib npaug rau cov kab laug sab laug los ntawm lub ejector, uas yog qhov zoo dua li qhov seem seem ntawm qhov kub khiav zoo tib yam. Nws yog ib qho tseem ceeb rau PET preforms nrog cov kev xav tau zoo ntawm qhov chaw, thiab tuaj yeem txo qhov kev xav tau ntawm cov khoom lag luam tom ntej qhov rooj txo cov haujlwm. PET preform pwm siv qhov loj - txoj kab uas hla pub lub rooj vag kom ceev cov yaj sau nrawm thiab ua kom luv rau lub voj voog txhaj tshuaj molding; it can also accurately control the holding time and pressure distribution, improve the density uniformity of the preform, reduce the risk of shrinkage and deformation of the preform, and improve the overall stability and strength of the preform. Lub kaw lus kub khiav tsis txhob tsim cov khoom siv txias khiav pov tseg thiab ncaj qha txo tus nqi ntawm cov khoom siv raw; Nyob rau tib lub sijhawm, lub koob valve tsim muaj kev ntseeg tau zoo, txo cov khoom siv rov qab los yog xaim kos duab thaum qhib pwm, thiab ua kom muaj kev ruaj ntseg ntawm kev tsim khoom tas mus li.

Zoo ua ntej, Txhim khu kev qha zoo

 

Raws li S136 pwm steel muaj cov khoom siv hlau xws li Si, Cr, thiab Mn, oxide tiv thaiv txheej txheej ntawm nws sab nrauv, cais nws los ntawm dej hauv huab cua, kua qaub, thiab alkali oxidation cov tshuaj tiv thaiv, yog li tswj cov smoothness thiab stability ntawm cov khoom. Nws qhov siab - kub stability tiv thaiv pwm los ntawm deforming nyob rau hauv lub siab - kub txheej txheem ntawm PET lub raj mis preform txhaj molding, kom ntseeg tau siab zog thiab hardness, thiab tuav ntev - lub sij hawm ruaj khov ntawm cov pwm.

Kev ua tau zoo leap, Precision stability

 

PET preform pwm txais yuav ib qho -kab noj hniav tus kheej - xauv qauv. Nws xyuas kom meej tias txhua qhov kab noj hniav tseem nyob ntawm nws tus kheej kaw thaum lub sijhawm txhaj tshuaj molding txheej txheem hauv ntau -kab noj hniav PET preform txhaj tshuaj molding txheej txheem. Qhov kev tsim no ua rau siab precision thiab tus nqi qis hauv qhov kawg preform ntau lawm. Tus tsim muaj peev xwm txo tau cov phab ntsa thickness sib txawv ntawm lub preform, kom ntseeg tau zoo sib xws thiab zoo ntawm cov khoom.

PET preform txhaj tshuaj molding yog siv cov zaub mov-qib polyethylene terephthalate (PET) resin pellets. Cov pellets no muaj cov pob tshab siab, lub zog zoo heev, thiab cov khoom siv roj hmab. Vim lub siab hygroscopicity ntawm PET resin, PET pellets yuav tsum tau qhuav nyob rau hauv ib tug dehumidifying tshuab ua ntej pub, nrog rau qhov kub thiab txias tswj ntawm 150-180℃rau kwv yees li 4-6 teev, kom ntseeg tau tias cov resin noo noo cov ntsiab lus yog txo mus rau ib tug ntau npaum li cas. Qhov no tiv thaiv kev cuam tshuam rau cov khoom siv kho tshuab thiab cov tsos. Yog tias cov khoom siv rov ua dua tshiab (xws li huv, crushed preforms) raug ntxiv thaum lub sij hawm tsim khoom, lawv qhov kev faib ua feem yuav tsum raug tswj qis dua 10% kom tsis txhob muaj kev ua haujlwm tsis zoo. Lub℃ntawm dryness thaum pretreatment ncaj qha txiav txim siab stability ntawm cov khoom PET preform thiab yog ib qho tseem ceeb los xyuas kom meej ib tug siab tiav cov khoom tawm los.

Cov engineers yuav tsum tau siv CAD software los ua kom tiav 3D qauv tsim raws li cov qauv ua ntej cov qauv, phab ntsa thickness, xov specifications, thiab lwm yam yuav tsum tau siv. Lawv siv CAE software rau pwm khiav kev tsom xam thiab kev sim ua kom txias kom zoo rau qhov kev sib tw khiav thiab kev sib pauv cua sov. Tus qauv tsim yuav tsum tsom rau cov kab noj hniav (feem ntau yog 8-96 kab noj hniav), hom rooj vag (tsuas yog kub khiav koob valve hom / taw tes rooj vag), thiab cov cua txias channel layout los xyuas kom meej uniform filling thiab ceev ceev ntawm cov yas thaum txhaj molding. Kev xaiv cov khoom siv rau PET koob valve preform pwm yog qhov tseem ceeb. Cov tub ntxhais pwm / kab noj hniav feem ntau yog ua los ntawm corrosion-tiv taus, hnav heev- tiv taus siab- zoo stainless hlau (xws li S136, AISI422), thaum lub phaj pwm siv pre-hardened steel (xws li P20, 4Cr13). Tom qab cov duab kos duab tsim tawm, txoj kev ua haujlwm yuav tsum tau npaj ib txhij, thiab cov qauv kev ua siab ntev (feem ntau ± 0.01mm) yuav tsum tau tsim los tsim cov txheej txheem rau kev tsim khoom tom ntej.

Younce yog ib lub chaw tsim khoom ntawm PET preform pwm nyob rau hauv Suav teb rau lub raj mis dej, khoom noj khoom haus, thiab cov roj ntim khoom noj. Txais tos nug.

1, PET preform pwm yog dab tsi?

PET preform pwm yog cov cuab yeej tsim khoom tsim nyog hauv kev lag luam ntim cov dej haus, cov roj siv tau, cov khoom noj, thiab cov tshuaj niaj hnub, thiab nws cov kev xav tau ntawm kev lag luam yog txuas nrog rau cov neeg siv khoom lag luam. Kev lag luam kev lag luam ntawm pwm yog nyob rau hauv lawv "ib- lub sij hawm peev, ntev - lub sij hawm tso tawm" yam ntxwv. Txawm hais tias thawj zaug peev hauv ntau cov kab noj hniav precision ntawm pwm yog qhov tseem ceeb, los ntawm kev siv tag nrho cov kev txhaj tshuaj hnyav, qhov chaw nruab nrab ntawm cov hlua khi, thiab lwm yam khoom ntawm lub tshuab txhaj tshuaj molding, cov nqi tsim khoom ntawm ib qho PET preform tuaj yeem txo qis. Pwm tsim ncaj qha cuam tshuam rau kev siv tus nqi ntawm cov khoom siv raw (PET hais); optimized casting thiab txias tsim tuaj yeem txo cov khoom pov tseg thiab siv zog. Pwm cov nqi tu thiab qhov yooj yim ntawm kev hloov qhov tsis zoo yog qhov tseem ceeb hauv kev ntsuas lawv lub neej- voj voog kev lag luam.

2, Dab tsi yog qhov sib txawv ntawm PET preform pwm?

PET preform pwm tuaj yeem muab faib ua ntau hom PET preform pwm (tsis yog-tus kheej- kaw), tus kheej- kaw PET preform pwm, thiab tus pin valve tus kheej- kaw PET preform pwm raws li cov qauv, khoom siv, kub khiav, thiab lwm yam.

3, Dab tsi yog PET preform pwm (tsis yog-tus kheej- kaw)?

Common PET preform pwm (tsis yog-tus kheej-locking hom) yog qhov zoo tshaj plaws thiab yooj yim hauv cov qauv. Nws cov txiaj ntsig suav nrog kev nqis peev qis qis, rov qab tau tus nqi sai, thiab kev saib xyuas yooj yim. Cov tub ntxhais / kab noj hniav feem ntau siv cov ntaub ntawv xws li 38Cr13 thiab 3Cr13. Txawm li cas los xij, vim muaj kev cuam tshuam ntawm 38Cr13 rau oxidation thiab corrosion los ntawm kev ua haujlwm ntev lossis kev saib xyuas tsis raug, nws tau raug tso tseg los ntawm cov tuam txhab feem ntau. Nws qhov tsis zoo suav nrog kev tsim lub neej luv dua (1 lab molding cycles), txawm hais tias kev kho kom zoo los ntawm cov tuam txhab preform tuaj yeem txuas ntxiv lub neej no.

4, Tus kheej -locked PET preform pwm yog dab tsi?

Tus kheej -locking PET preform pwm core / kab noj hniav yog ua los ntawm siab- pwm zoo, xws li 3Cr13/S136, thiab cov qauv yog ua los ntawm P20 pwm hlau. Nws lub neej tsim tau txuas ntxiv rau qhov zoo tib yam PET preform pwm, ncav cuag 1.5 txog 2 lab lub voj voog. Cov tub ntxhais pwm / kab noj hniav tau txais kev ywj pheej ntawm tus kheej -cov qauv ntsuas phoo, ua rau kev saib xyuas thiab hloov tau yooj yim. Hauv kev ua haujlwm zoo, nws qhov tsis zoo yog tib yam li cov pwm: hauv kev txhaj tshuaj molding kab ua haujlwm, lub tshuab txhaj tshuaj molding tsis tuaj yeem ua kom sov thiab ua ntej-plasticize.

5, Dab tsi yog tus pin valve tus kheej -locking PET preform pwm?

Tus pin valve tus kheej -locking PET preform pwm cov cores, kab noj hniav, thiab sliders yog machined nrog precision tswj nyob rau hauv ± 0.01mm. Qhov no nruj me ntsis tswj lub preform eccentricity thaum txhaj molding. Vim tias cov pwm siv rab koob valve tus kheej - cov qauv ntsuas phoo, cov kab ntau lawm tuaj yeem ua ib txhij tsim cov khoom thiab ua ntej -plasticizing ntawm lub tshuab txhaj tshuaj molding, npaj rau kev txhaj tshuaj tom ntej, thiab ua kom lub voj voog ntau lawm. Nws lub ntsiab kom zoo dua yog nyob rau hauv lub "point-to-taw tes" tswj qhov kub thiab txias, kom ntseeg tau tias cov khoom hnyav hnyav thiab phab ntsa tuab hauv txhua qhov kab noj hniav, yog li txhim kho cov khoom zoo.
