Cov Extrusion tshuab Moulding txheej txheem tsim ib tug ob-seem khoom whereas lub txhaj tshuaj molding txheej txheem tsim cov khoom peb-dimensional raws li qhov kawg tso zis. Qhov thib ob txawv lus dag hauv cuab yeej uas yog siv nyob rau hauv ob qho tib si txheej txheem.
Ntxiv mus, dab tsi yog extrusion tshuab Moulding?
Extrusion Tshuab Moulding yog hom yooj yim tshaj plaws tshuab molding . Ib lub raj kub ntawm cov khoom yas, hu ua parison, yog poob los ntawm ib qho extruder thiab ntes nyob rau hauv ib tug dej txias pwm. Thaum cov pwm raug kaw, huab cua yog txhaj los ntawm sab saum toj lossis lub caj dab ntawm lub thawv; ib yam li ib tug tshuab up ib balloon.
Ib yam li ntawd, lub tshuab Moulding yog dab tsi? Tshuab molding (BrE molding ) yog ib qho kev tsim khoom tshwj xeeb txheej txheem los ntawm qhov uas hollow yas seem yog tsim thiab tuaj yeem koom ua ke. Nws kuj yog siv los ua cov iav fwj los yog lwm yam hollow duab. Lub parison yog ces clamped rau hauv pwm thiab cua yog tshuab rau hauv nws.
Thiab cov lus nug yog, dab tsi yog qhov preform hauv tshuab molding?
Tshuab molding yog cov txheej txheem ntawm kev tsim lub raj molten (hu ua parison los yog preform ) ntawm cov khoom siv thermoplastic (polymer lossis resin) thiab muab cov parison los yog preform hauv ib pwm kab noj hniav thiab inflating lub raj nrog compressed cua, coj cov duab ntawm kab noj hniav thiab txias ib feem ua ntej tshem tawm ntawm lub pwm.
Vim li cas lawv thiaj hu ua tshuab moulds?
Cov duab tau hu ua tshuab moulds vim lawv tau ua los ntawm hollow hard yas uas tau tsim nyob rau hauv ib pwm . Lawv muaj cov xim yas hauv qee qhov chaw lossis raug pleev xim tom qab hardening.

Fertilizer injectors yog cov cuab yeej siv los siv cov dej-soluble chiv, tshuaj tua kab, cog kev loj hlob regulators, wetting agents thiab mineral acids thaum cog qoob loo. Lawv yog ib feem tseem ceeb ntawm kev cog qoob loo niaj hnub no lossis kev zov me nyuam
Dab tsi yog qhov txawv ntawm cov tshuab yooj yim thiab cov tshuab sib xyaw?
Qhov sib txawv ntawm cov tshuab yooj yim thiab cov cav tov sib xyaw ➡ Cov cav tov sib xyaw yuav muaj ntau yam thiab suav tsis tau ua ke ntawm cov tshuab yooj yim. Lub tshuab yooj yim yog lub tshuab ob peb lossis tsis muaj qhov txav. Lub tshuab ua ke yog lub tshuab uas muaj ob lossis ntau lub tshuab ua haujlwm yooj yim ua ke kom ua haujlwm yooj yim dua
Dab tsi yog qhov txawv ntawm qhov ua tau zoo thiab cov khoom lag luam teb thiab cov ntsiab lus ntawm kev lag luam uas txhua qhov ua haujlwm zoo tshaj?
Lub tuam txhab muaj peev xwm ua kom tau raws li cov neeg siv khoom xav tau raws sijhawm yog hu ua Kev Ua Haujlwm Zoo, thaum ua haujlwm tau zoo yog lub tuam txhab muaj peev xwm xa khoom raws li tus neeg siv khoom xav tau nrog tsawg kawg ntawm cov khoom siv raw, kev ua haujlwm thiab tus nqi
Dab tsi yog extrusion tshuab Moulding?
Hauv Extrusion Tshuab Moulding (EBM), yas yog yaj thiab extruded rau hauv lub raj hollow (ib lub parison). Cua yog ces cua tshuab mus rau hauv lub parison, inflating nws mus rau hauv cov duab ntawm lub hollow lub raj mis, thawv, los yog ib feem. Tom qab cov yas tau txias txaus, cov pwm qhib thiab qhov chaw raug tshem tawm
