PET Preform Neck Finish Guide: Yuav Ua Li Cas Xaiv Lub Cwj Pwm Zoo

Thaum yuav khoomPET preforms, ntau tus neeg muas zaub tsom ua ntej ntawm qhov hnyav preform, lub raj mis muaj peev xwm, thiab cov khoom siv. Cov xwm txheej no tseem ceeb, tab sis lub caj dab tiav yog qhov tseem ceeb sib npaug.

Lub caj dab tiav txuas lub raj mis thiab lub hau. Nws cuam tshuam rau cap compatibility, sealing kev ua tau zoo, thiab ntau lawm efficiency. Yog tias xaiv lub caj dab tsis ncaj ncees lawm, txawm tias qhov siab tshaj - zoo preform yuav ua rau kom tawg, capping teeb meem, lossis kev cuam tshuam ntau lawm.

Raws li cov qauv ntim khoom PET txuas ntxiv txhim kho, ntau lub tuam txhab tau saib xyuas kev xaiv ua tiav ntawm caj dab. Phau ntawv qhia no piav qhia txog PET preform caj dab cov qauv, hom caj dab hom, xaiv txoj kev, thiab cov ntsiab lus tseem ceeb los xyuas ua ntej muab qhov kev txiav txim.

1. PET Preform Neck Finish yog dab tsi?

PET preform muaj peb qhov tseem ceeb: lub caj dab tiav, lub cev, thiab lub hauv paus.

Lub caj dab tiav yog tsim thaum lub sij hawm txhaj tshuaj molding txheej txheem. Tsis zoo li lub raj mis lub cev, lub caj dab cheeb tsam ib txwm khaws nws cov qauv qub thaum lub tshuab molding. Qhov no txhais tau hais tias lub caj dab raug ncaj qha cuam tshuam rau lub raj mis zaum kawg.

PET preform caj dab tiav suav nrog peb qhov tseem ceeb:

Xov

Cov xov tso cai rau lub kaus mom txuas kom raug. Cov qauv caj dab sib txawv siv cov xov sib txawv, yog li lub kaus mom tsis tuaj yeem hloov pauv ntawm cov caj dab sib txawv.

Sealing nto

Lub sealing nto hu rau sab hauv ntawm lub hau. Ib qho chaw sib khi zoo thiab ruaj khov pab tiv thaiv kom tsis txhob tawm thiab tswj lub raj mis kev nyab xeeb thaum khaws cia thiab kev thauj mus los.

Txhawb Nplhaib

Lub nplhaib txhawb pab muab qhov preform thaum tuav, cua sov, thiab tsis siv neeg ntau lawm. Lub nplhaib txhawb nqa ruaj khov tsim txhim kho kev tsim khoom sib xws.

Cias muab, lub caj dab tiav txiav txim peb yam:

• Seb lub kaus mom haum kom raug
• Seb lub raj mis tuaj yeem kaw
• Seb lub preform ua haujlwm nrog cov khoom siv ntau lawm

2. Vim li cas PET Preform Neck Finish Matters

Qee tus neeg yuav khoom xav tias lub caj dab tiav tsuas yog qhov loj me, xws li 28mm, 38mm, lossis 55mm. Hauv kev tsim khoom tiag tiag, lub caj dab tiav yuav tsum ua kom haum lub hau, khoom siv, thiab daim ntawv thov zaum kawg tib lub sijhawm.

Lub raj mis Cap Compatibility

Lub caj dab sib txawv yuav tsum muaj cov kaus mom sib txawv.

Piv txwv li, PCO 1881 thiab PCO 1810 yog ob qho tib si 28mm caj dab tiav, tab sis lawv cov qauv xov thiab qhov ntev yog txawv. Lub kaus mom tsim rau ib tus qauv yuav tsis haum rau lwm tus.

Xaiv lub caj dab tsis ncaj ncees lawm yuav ua rau muaj teeb meem thaum lub sij hawm sau thiab ntim khoom.

Sealing Performance

Lub caj dab tiav ncaj qha cuam tshuam rau kev ua haujlwm sealing.

Yog tias lub caj dab thiab lub kaus mom tsis sib haum, cov teeb meem tshwm sim muaj xws li:

• Ua kua dej
• Gas poob
• Loose kaus mom

Cov teeb meem no yuav tsis tshwm sim thaum lub sijhawm yuav khoom. Lawv feem ntau tshwm sim tom qab sau, kev thauj mus los, lossis kev xa khoom, uas tuaj yeem nce nqi hloov pauv thiab rov qab los.

Ntau lawm kab Compatibility

Lub caj dab tiav kuj yuav tsum sib phim:

• Tshuab moulding tshuab
• Cov tshuab filling
• Capping tshuab

Yog tias lub caj dab tsim tsis haum rau cov khoom siv, cov kab ntau lawm yuav muaj kev ua haujlwm tsis ruaj khov, kev hloov kho tsis tu ncua, lossis kev poob qis.

3. Hom PET Preform Neck Finish hom

Cov khoom sib txawv xav tau cov caj dab sib txawv.

Cov hauv qab no yog qee yam PET preform caj dab tiav siv hauv khw:

Qhov tseeb caj dab tiav nyob ntawm cov khoom.

Cov fwj dej feem ntau tsom rau kev tsim qauv hnyav thiab siab - ceev ntau lawm.

Cov ntim dej loj xav tau lub caj dab muaj zog rau kev thauj mus los thiab rov ua dua.

Cov thawv ntim khoom noj feem ntau xav tau qhov qhib dav dua rau kev sau thiab siv yooj yim.

4. PCO 1881 vs PCO 1810: Qhov txawv yog dab tsi?

PCO 1881 thiab PCO 1810 yog ob hom qauv 28mm caj dab.

Txawm hais tias lawv zoo sib xws, lawv tau tsim los rau kev siv sib txawv.

PCO 1881 tau dhau los ua neeg nyiam tshaj plaws hauv kev ntim dej haus niaj hnub no vim nws lub teeb yuag.

Rau qhov ntim ntau lawm, lub teeb sib dua tuaj yeem txo cov khoom siv PET thiab txo cov nqi ntim khoom.

Txawm li cas los xij, cov neeg yuav khoom yuav tsum tsis txhob hloov cov qauv caj dab nkaus xwb vim tias txuag cov khoom siv.

Yog tias lub Hoobkas twb siv cov kaus mom tshwj xeeb, pwm, thiab cov khoom siv ntau lawm, kev hloov lub caj dab tiav yuav tsum tau kuaj xyuas qhov ua tiav ntim khoom ua ntej.

5. Yuav Ua Li Cas Xaiv Txoj Cai PET Preform Neck Finish

Xaiv lub caj dab kom yog yuav tsum tau xyuas ntau yam tseem ceeb.

• Kua txiv
• Noj roj
• 5 nkas loos dej fwj
• Cov hub zaub mov

Daim ntawv thov sib txawv xav tau cov caj dab sib txawv.

Piv txwv li:

500ml dej fwj feem ntau siv 28mm lossis 29/25 caj dab tiav.

5 nkas loos dej fwj feem ntau siv 55 hli caj dab tiav.

Cov hub zaub mov feem ntau siv dav - lub qhov ncauj qhov ncauj tiav xws li 63mm, 83mm, lossis 89mm.

Match Lub Cap Thiab Cov Khoom Siv

Ua ntej xaj, paub meej tias:

• Cap hom
• Cap loj
• Cov khoom siv filling

• Xov loj
• Txhawb lub nplhaib txoj hauj lwm
• Sealing nto flatness

Lub caj dab ruaj khov qhov ntev pab ua kom lub ntsej muag zoo ib yam.

Sealing Thiab Production Tests

Ua ntej ntau lawm, cov neeg muag khoom yuav tsum ua:

• Kev ntsuam xyuas kev sib tw
• Tshuab moulding xeem
• Kev ntsuam xyuas qhov dej

Cov kev ntsuam xyuas no pab txheeb xyuas cov teeb meem uas yuav tshwm sim ua ntej loj - nplai ntau lawm.

Kev tshuaj xyuas cov khoom

Cov khoom ntim khoom noj preforms yuav tsum tau kuaj xyuas rau:

• PET khoom zoo
• IV tus nqi
• Qib Acetaldehyde (AA).
• Pob tshab
• Phab ntsa thickness sib xws

Cov xwm txheej no cuam tshuam txog kev nyab xeeb ntawm lub raj mis, qhov zoo li, thiab kev ua haujlwm ntev -.
