Hauv kev lag luam niaj hnub no, tag nrho tsis siv neeg hollow tshuab moulding tshuab ua lub luag haujlwm tseem ceeb. Lawv yog cov cuab yeej muaj peev xwm ua tau zoo thiab raug tsim cov khoom yas hollow, dav siv hauv ntau yam lag luam xws li zaub mov, dej haus, thiab tshuaj pleev ib ce. Yog li, dab tsi yog qhov tsis siv neeg hollow tshuab moulding tshuab, thiab nws cov qauv kev ua haujlwm thiab cov yam ntxwv yog dab tsi? Cia peb tshawb nrhiav qhov tob tob.
Ua ntej, cia peb nkag siab lub ntsiab lus ntawm lub siab tsis siv neeg hollow tshuab moulding tshuab. Lub tshuab tsis siv neeg hollow tshuab moulding tshuab yog lub tshuab uas siv lub raj yas preform tau los ntawm extrusion los yog txhaj tshuaj molding ntawm thermoplastic yas, muab tso rau hauv ib lub pwm cais thaum nws tseem kub (los yog rhuab mus rau ib tug softened xeev), thiab tam sim ntawd tom qab pwm kaw, compressed cua yog nkag rau hauv lub preform, ua rau nws inflate thiab adhere nruj nreem rau lub puab phab ntsa ntawm pwm. Tom qab txias thiab demolding, ntau yam khoom hollow tau txais.
Tsis siv neeg hollow tshuab moulding tshuab muaj ntau yam ntxwv tseem ceeb. Ua ntej, lawv muaj qib siab ntawm automation. Los ntawm kev xa khoom, cua sov, thiab molding ntawm cov ntaub ntawv yas raw khoom mus rau demolding ntawm cov khoom tiav, tag nrho cov txheej txheem tuaj yeem ua haujlwm tau zoo, txhim kho kev tsim khoom zoo heev thiab txo cov kev cuam tshuam ntawm phau ntawv thiab kev siv zog. Cov neeg ua haujlwm tsuas yog yuav tsum tau teeb tsa qhov tsis sib xws, thiab lub tshuab tuaj yeem ua haujlwm ruaj khov raws li qhov kev pabcuam preset, ua kom cov khoom zoo sib xws. Secondly, nws boasts siab precision ntau lawm. Los ntawm kev tswj hwm qib siab thiab cov qauv tsim pwm, nws tuaj yeem tswj qhov loj thiab cov duab ntawm cov yas preform, ua cov khoom hollow nrog cov phab ntsa tuab tuab thiab qhov tseeb, ua tau raws li cov kev cai nruj ntawm ntau yam kev lag luam. Thirdly, nws muaj zog siv tau. Nws tuaj yeem ua ntau yam thermoplastics, xws li polyethylene (PE), polypropylene (PP), thiab polyvinyl chloride (PVC), ua cov khoom hollow ntawm ntau yam duab thiab siv, xws li lub raj mis yas, thoob yas, thiab cov thawv yas, dav siv nyob rau hauv txawv teb.
Tom ntej no, cia peb saib cov kev ua haujlwm ntawm lub siab tsis siv neeg hollow tshuab moulding tshuab. Thawj kauj ruam yog kev npaj cov khoom siv yas. Cov yas granules uas tsim nyog tau muab tso rau hauv lub hopper, thiab cov ntaub ntawv raw yog xa mus rau lub thoob rhuab los ntawm cov ntsia hlau conveyor system. Qhov thib ob theem yog cua sov thiab plasticizing. Nyob rau hauv lub rhuab chim, cov yas granules yog rhuab mus rau ib tug molten lub xeev, ua ib tug yas yaj nrog zoo fluidity. Qhov thib peb kauj ruam yog preform ua. Cov yas yaj yog extruded los yog txhaj rau hauv tubular preform los ntawm extruder lossis txhaj tshuaj molding tshuab. Kauj ruam plaub yog tshuab molding. Lub preform yog muab tso rau hauv pwm, thiab tom qab lub pwm raug kaw, compressed cua yog nkag mus rau hauv lub preform, ua rau nws nthuav thiab adhere nruj nreem rau lub puab phab ntsa ntawm cov pwm, tsim cov khoom xav tau hollow. Cov kauj ruam kawg yog txias thiab demolding. Cov khoom yog txias thiab solidified siv pwm lub tshuab txias, thiab tom qab ntawd cov pwm qhib thiab cov khoom raug tshem tawm.
Tsis siv neeg hollow tshuab moulding tshuab muaj kev cuam tshuam loj rau kev tsim khoom. Lawv qhov tshwm sim tau txhawb nqa qhov loj - cov khoom loj ntawm cov khoom yas hollow, ua tau raws li kev lag luam xav tau rau ntau yam khoom hollow. Nyob rau tib lub sijhawm, lawv cov kev ua haujlwm siab -kev ua tau zoo thiab cov peev txheej molding muaj peev xwm pab txhim kho cov khoom zoo thiab kev tsim khoom, txo cov nqi tsim khoom, thiab txhim kho kev lag luam kev sib tw ntawm cov lag luam.
