Kev ua thiab siv cov yas moulding tshuab yog ib qho cuab yeej siv tshuab, uas cuam tshuam nrog ntau yam txheej txheem uas hloov pauv rau hauv cov khoom yas. Thaum lub sijhawm hloov pauv, ib lossis ntau yam ntawm cov xwm txheej hauv qab no feem ntau tshwm sim, xws li cov rhheology ntawm cov polymer thiab cov khoom siv tshuaj lom neeg.
Nias Taus
Cov khoom siv tseem ceeb siv rau compression moulding yog xovxwm thiab pwm. Cov siv dav tshaj plaws yog tus kheej muaj cov xovxwm hydraulic, nrog tonnage lizens ntawm kaum ob rau ntau pua ntawm tons. Muaj cov xovxwm thiab nce nias. Cov pwm siv rau compression moulding yog hu ua nias pwm thiab muab faib ua peb pawg; Overflow pwm, semi-txev pwm tsis dhau pwm. Lub ntsiab kom zoo ntawm compression moulding yog tias nws tuaj yeem pwm cov khoom lag luam loj dua thiab cov kev tsis sib haum yog tias kev ua haujlwm ntev yog qhov tsawg.
Txhaj Tshuaj Molding
Laminating yog feem ntau ua haujlwm nrog laminating tshuab, uas muaj ntau txheej ntawm cov phaj kub ntawm cov phaj sib xyaw thiab phaj ruaj. Cov ntaub ntawv feem ntau siv rau Laminating yog daim ntaub paj rwb, iav iav, thiab lwm yam, thiab ib co thermoplastic resins. Kev txhaj tshuab moulding moulding tshuab moulding tshuab moulding flue txau hluav taws xob txau hluav taws xob txau.
Txiav tawm moulding
Extrusion Molding tseem hu ua extrusion molding lossis extrusion, nws yog nyob rau hauv extruder los ntawm cua sov, siab thiab ua rau cov khoom ntws los ntawm lub qhov ncauj moulding txoj kev. Qhov kev rho tawm cov kev rho tawm yog siv rau kev yoog raws li thermoplastics thiab tseem siv tau rau qee qhov thermosetting plastics. Extruded khoom yog cov tsiaj ntawv txuas ntxiv, xws li cov raj, pas nrig, hlau daim hlau, cov yeeb yaj kiab, xaim thiab cable cladding. Ib qho ntxiv, nws tseem tuaj yeem siv rau kev sib xyaw yas, cov granulation yooj yim, pleev xim, sib xyaw thiab lwm yam. Cov Extrusion sib sau tshuab yog tsim ntawm Extrusion cov cuab yeej siv thiab kev sib kis tshuab thiab cua sov thiab cua txias. Extruders muaj ob hom: ntsia hlau hom (ib leeg ntsia hlau thiab ntau ntsia hlau) thiab cov phiaj xwm plunger. Cov txheej txheem Extrusion qub yog txuas ntxiv, tom kawg yog kev sib deev. Cov qauv yooj yim ntawm tib lub ntsia hlau Extruder tsuas yog siv cov cuab yeej kis tau, them cov cuab yeej, chim, ntsia hlau, taub hau thiab qhov ncauj tuag. Ntu cov khoom siv ntawm Extruder muaj peb pawg ntawm cov khoom siv pretreatment (shating, txias, txiav lossis yob) thiab ntau lawm txwv tswj cov khoom siv.
Extrusion Sib Sau
Extrusion Molding yog ib qho ntawm cov txheej txheem sib sau ntawm thermosetting fiber ntau ntxiv kom muaj teeb meem. Nws yog siv los tsim cov ntaub ntawv nrog ntu ntu thiab tsis muaj kev txwv ntev. Cov txheej txheem moulding yog mus rub tawm cov fiber ntau nras fiber ntau nrog cov kua nplaum uas tsis muaj zog los ntawm kev siv cua sov los ntawm kev siv hluav taws xob kub siab tam sim no.
Feem ntau siv rau extrusion moulding resins tsis tau txais polyester, epoxy thiab silicone peb yam. Unsaturated polyester resin yog qhov siv tshaj plaws. Extrusion Molding tshuab feem ntau yog tsim cov cuab yeej fiber ntau, cov khoom siv hluav taws xob, cov khoom siv thiab cua sov thiab cov khoom siv traction.
