Tshuab Moulding Txheej txheem (HOLLOW TSHUAB MOULING)
Tshuab moulding, kuj hu ua Hollow tshuab moulding, yog kev tsim cov txheej txheem yooj yim yas. Thermoplastic Resins yog extruded lossis txhaj-mould-molded rau tubular yas, thiab tom qab ntawd muab tso rau hauv kev sib cais pwm thaum tseem kub (lossis rhuab rau lub xeev muag muag). Sai li sai tau tom qab kaw cov pwm, compressed cua nkag rau hauv cov parison, ua rau nws nthuav dav thiab tightly ua raws li sab hauv phab ntsa ntawm cov pwm. Tom qab txias thiab ntiab tawm pwm, ntau yam hollow cov khoom tau txais.
Pwm Txheej Txheem: Kev tshem tawm ntawm Parison: Molten Yas yog extruded lossis txhaj-mould-mould-moulded los ua ib lub tubular paronis, tom qab ntawd muab tso rau hauv ib qho qhib pwm. Cov parison yog tswj hwm ntawm qee qhov kub kom ntseeg tau nws nyob tseem yas.
Pwm kaw: Lub Extruded Parison tau muab tso rau hauv kev sib cais pwm. Ob lub malves ntawm cov pwm kaw, sib sau qhov chaw sib khi hauv kev npaj rau cov kauj ruam tom ntej.
Tshuab: tam sim ntawd tom qab cov pwm kaw, cov cua compressed rau hauv parison los ntawm qhov cua hauv cov pwm. Lub tshuab pa hluav taws xob sai sai nthuav cov parison, ua rau nws ua kom nruj nreem rau sab hauv phab ntsa ntawm cov pwm. Cov kauj ruam no ua kom ntseeg tau tias cov duab thiab qhov loj me ntawm cov khoom yas phim cov pwm.
Cua txias thiab tso tshuaj lom: Lub tshuab tshuab yas yas cov khoom txias thiab ua kom zoo nkauj hauv cov pwm. Thaum nws yog txaus txias thiab muaj kev sib cais, cov pwm qhib, thiab cov khoom yog ejected.
TRIMMING: Cov khoom laij yuav xav tau Trimming, xws li tshem tawm cov ntaub ntawv ntau dhau los yog txiav qhov qhib. Cov khoom trimmed yog qhov kawg Hollow yas khoom.
Sau ntawv: Lub tshuab moulding yog haum rau ntau yam thypogylene plastics, py cypinylene plastide (pyypinylene (py can. khoom. Lub tshuab moulding cov khoom tuaj yeem tsim cov kua roj yas ntawm ntau yam duab thiab ntau thiab nws tau siv dav hauv cov khoom ntim, cov khoom ua si, chaw ua lag luam, thiab lwm thaj teb.
