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.
