Tshuab moulding thiab sib hloov moulding yog ob yam yas ua thiab moulding txheej txheem. Lawv ua haujlwm ntawm cov ntsiab cai sib txawv thiab haum rau cov khoom sib txawv.
Cias muab:
Tshuab moulding: zoo li tshuab ib lub zais pa, nws yog feem ntau ua hollow, nyias {{}} walled cov khoom (xws li fwj thiab dej kas).
Nws yog ib lub pob khoom qab zib ua ke, nws feem ntau ua tiav nrog, hollow {} Cov khoom lag luam, cov tsheb nqaj hlau loj, thiab ntab).
Hauv qab no, peb muab cov ncauj lus kom ntxaws los ntawm ntau qhov kev xav.

Nta Tshuab Molding Moulding
Cov txheej txheem tseem ceeb: ib qho rhuab, cov parison muag muag tau muab tso rau hauv cov pwm. Compressed cua yog tshuab tshuab ua pwm, ua rau nws nthuav dav thiab ua raws li cov pwm kab noj hniav. Txias ces teeb cov pwm. Cov hmoov yas ntxiv rau cov pwm, uas yog tom qab ntawd txuas ntxiv txuas raws ob lub axes nyob rau hauv ib lub rhuab chamber. Cov hmoov melts thiab adheres tusyees rau sab hauv phab ntsa ntawm cov pwm kab noj hniav. Txias teeb tsa cov pwm rau hauv nws qhov kev xav tau.
Cov khoom siv raw feem ntau yog cov granules yas, uas yog thawj tus kheej rau hauv lub tubular paronis. Qhov no feem ntau yog cov hmoov yas thiab yuav tsum sib tsoo zoo heev.
Mould Cov nqi: Tus nqi siab (tshwj xeeb tshaj yog rau kev txhaj tshuab tshuab moulding), raws li cov pwm yuav tsum ua kom muaj lub siab tiv thaiv siab. Tus qauv tsawg, raws li cov qauv pwm yog qhov yooj yim thiab tsis xav tau siab siab. Kev ua haujlwm ntau lawm yog ntau, nrog kev sib koom ua ke Mycles (kaum ob sab nrauv), haum rau loj {2} teev ntau lawm. Tsawg heev, nrog ntev moling cycles (feeb mus rau kaum feeb), haum rau me me- nplai ntau lawm.
Cov Khoom Nta: -} Cov Phab Ntsa Thickness (Tshwj xeeb hauv cov ces kaum)
-} parting kab thiab rooj vag cim yog tam sim no
{{0- Feem ntau siv rau qhib qhov chaw (xws li lub raj mis lub raj mis)} {1} Zem
{{0 {}}} Tsis muaj ib ntu, tso cai rau cov kab hauv qab
{{0- me ntsis tsis zoo saum npoo nthuav dav dav dav
Cov Khoom Uas Raug: Cov taub dej me, cov roj zawv plaub hau, cov hlau dej los, roj roj, {{{}} phab ntsa Tooles, thiab lwm yam; Cov thawv ntim khoom loj (dej tso tsheb hlau luam, tso tsheb hlau luam, kayaks, floats, tsheb cones, cov menyuam roj hmab, ntu tsheb, thiab lwm yam.
Cov khoom lag luam loj: Txwv los ntawm Paron Schis Stret Ratio, feem ntau yog siv rau me me thiab nruab nrab - qhov loj me. Qhov zoo tagnrho rau kev tsim khoom loj / ntxiv- loj hollow qhov chaw, uas loj me tsuas yog txwv ntawm cov pwm thiab khoom siv.
Phab Ntsa Thickness Tswj: Kho phab ntsa Thickness ntawm cov chaw sib txawv tau tiav los ntawm cov txheej txheem parison, ib txheej txheem nyuaj. Feem ntau yog tswj los ntawm cov hmoov ntawm hmoov ntxiv, lub phab ntsa tuab yog niaj hnub hnav, ua rau nws yooj yim kom tuab {1}- Walled khoom.
Cov lus qhia ntxaws ntxaws
1. Tshuab Moulding
Txheej txheej:
Extrusion ntawm tus parison yas yog rhuab thiab melted los ntawm extruder, sib sau lub tubular parison nrog lub hauv qab kaw.
Tuaj Kaw: Cov pwm hloov zuj zus mus, clamping lub parison.
Tshuab: rab koob tshuab tawg rau hauv cov parison, txhaj siab} lub siab cua rau hauv cov yas muag muag rau hauv phab ntsa txias.
Txias thiab kev sib sau: tom qab cov khoom txias tsis pub dhau lub pwm, pwm tau qhib, cov khoom raug tshem tawm, thiab txiav tau kev txiav tawm.
Qhov Zoo:
Cov peev txheej siab heev, haum rau loj - nplai ntau lawm, thiab chav qis nqi.
Cov khoom lag luam tawv nqaij, txuag cov khoom.
Tuaj yeem tsim cov khoom lag luam nrog cov khoom siab siab (xws li cov tsiaj lub hwj).
Qhov tsis zoo:
Tus nqi pwm siab.
Tsis tsim nyog rau kev tsim ua tiav hollow seem (yuav tsum muaj "chaw nres nkoj tawg").
Nyuaj ua rau muaj cov khoom lag luam.
2. Rotomolding
Txheej txheej:
Pub mis: Ntsuas ntsuas qhov ntsuas tau yooj yim ntawm cov hmoov yas tau ntxiv rau cov pwm hollow.
Cua sov thiab kev sib hloov: Cov pwm muab tso rau hauv chav sov (xws li lub qhov cub) thiab maj mam tig raws ob txoj kab sib tsoo.
Qhuav thiab adhesion: cov hmoov melts thaum lub sijhawm sib hloov, yog maj mam thiab tusyees coated thiab adhered rau tag nrho sab hauv ntawm cov pwm.
Txias thiab teeb tsa: Cov pwm hloov mus rau qhov chaw txias txias, qhov uas nws txuas ntxiv mus tig thiab ua tau zoo los ntawm huab cua lossis dej txias.
Pwm Qhib Thiab Kev Tshem Tawm: Kev sib hloov nres, cov pwm qhib, thiab qhov ua tiav tau raug tshem tawm.
Qhov Zoo:
Tsawg tus nqi thiab luv dua voj voog.
Yuav luag tsis muaj kev ntxhov siab sab hauv, cov khoom lag luam zoo heev.
Tuaj yeem tsim cov nyom tsis muaj zog, ob npaug - txheej, lossis txawm ntau- txheej pob.
Yooj yim hloov xim thiab cov khoom siv, nrog cov ntawv me me.
Qhov tsis zoo:
Ntev ntau lawm voj voog thiab tsis muaj kev ua tau zoo.
Kev noj hluav taws xob siab (tag nrho cov pwm yuav tsum tau ua kom sov).
Cov ntaub ntawv raw qis (yuav tsum muaj cov hmoov av), nrog tsawg dua cov khoom siv uas tsis yog tshuab moulding.
Cov ntsiab lus ntawm yuav ua li cas xaiv
Xaiv tshuab moulding yog tias koj xav tau tsim loj- volume, nruab nrab} Fwj yog tus piv txwv ua piv txwv. Kev ua tau zoo thiab tus nqi yog qhov kev txiav txim siab tseem ceeb.
Xaiv cov khoom moulding yog tias koj xav tau los tsim cov me me {0} {{{1} {{{2} {polled cov khoom lag luam. Piv txwv li cov tso tsheb hlau luam loj, kayaks, thiab cov khoom ua si loj. Cov khoom lag luam loj thiab cov nyom yog qhov tseem ceeb txiav txim siab, thiab ntau lawm kev ua haujlwm tsis tseem ceeb.
