Cov hauv qab no yog cov ntsiab lus ntawm kev tsim khoom:
I. Raw Material Preparation
Ua ntej, cov khoom siv yas, feem ntau yog polyethylene (PE) lossis lwm yam yas uas haum rau cov txheej txheem tshuab molding, tau npaj. Cov ntaub ntawv nyoos no tau muab tso rau hauv lub tshuab tov khoom uas lawv tau rhuab mus rau qhov kub thiab txias, softening thiab ua kom yooj yim rau cov txheej txheem. Qhov kub thiab lub sij hawm nyob rau hauv cov txheej txheem no yuav tsum nruj me ntsis tswj kom ntseeg tau tias cov ntaub ntawv raw yog melted tag nrho tsis degradation.
II. Parison Formation
Lub parison yog ib qho tseem ceeb ntawm cov khoom nruab nrab hauv cov txheej txheem tshuab molding. Nws tuaj yeem npaj los ntawm extruder lossis txhaj tshuaj molder. Nyob rau hauv extrusion tshuab molding, cov ntaub ntawv yas raw khoom yog rhuab thiab yaj nyob rau hauv ib tug extruder, ces extruded los ntawm ib tug parison tuag lub taub hau los tsim ib tug tubular parison. Hauv kev txhaj tshuaj molding, cov yas molten yog txhaj rau hauv parison txhaj pwm los ua ib qho kev xeem tube-zoo li parison. Qhov zoo ntawm parison yog qhov tseem ceeb rau kev tshuab molding tom ntej, xav tau cov phab ntsa tuab thiab du, tsis muaj qhov tsis xws luag.
III. Tshuab Moulding
Tshuab moulding yog qhov tseem ceeb ntawm cov txheej txheem. Thaum lub sij hawm no, lub rhuab parison yog pauv mus rau hauv lub tshuab pwm. Tom qab cov pwm raug kaw, compressed cua yog txhaj rau hauv lub parison kom nthuav nws tawm tsam cov phab ntsa ntawm cov pwm kab noj hniav. Lub tshuab siab thiab ceev yuav tsum tau tswj xyuas kom ntseeg tau tias lub parison nthuav dav tusyees thiab adheres rau cov pwm kab noj hniav, uas ua rau cov khoom yas nrog cov khoom uas xav tau thiab qhov ntev. Kev tuav lub tshuab ua kom siab kom txog thaum cov khoom yas txias thiab khov kho yog tsim nyog los xyuas kom meej qhov ruaj khov thiab qhov zoo.
IV. Khoom cua txias
Cov khoom cua txias yog cov kauj ruam kawg ntawm lub tshuab molding txheej txheem. Thaum lub sij hawm txias, lub tshuab siab thiab pwm kub yog maj mam txo kom cov khoom kom txias thiab solidify. Lub sijhawm txias yog nyob ntawm yam xws li cov khoom tuab, cov khoom siv, thiab pwm tsim. Thaum cov khoom tau txias tag nrho thiab khov kho, cov pwm tuaj yeem qhib kom khaws cov khoom rau kev ua haujlwm ntxiv.
V. Tom qab ua tiav
Tom qab retrieval, cov khoom yuav raug txiav, deburring, tu, thiab lwm yam tom qab ua cov kauj ruam los xyuas kom meej nws cov tsos zoo thiab nto tiav.
