Hluav taws xob hloov vaj huam sib luag thiab lub qhov (socket) vaj tse yuav tsum tau cov ntaub ntawv uas yog ob qho tib si nruj thiab muaj peev xwm ua tau raws li tus nqi, daim iav - zoo li ua tiav. High-gloss HIPS Granules tau dhau los ua lub luag haujlwm tseem ceeb hauv cov haujlwm no vim tias lawv muaj kev ruaj ntseg zoo thiab ua haujlwm yooj yim. Tsis zoo li lwm cov resins uas yuav tsum tau complex additives rau ci, cov granules yuav molded rau hauv du, ci nto ncaj qha los ntawm lub tshuab. Qhov kev ua tau zoo no txo qis qhov xav tau ntawm cov txheej txheem pleev xim los yog txheej txheej, uas ua rau txo qis tag nrho cov hneev taw thiab kev siv zog. Cov khoom siv kuj muaj cov khoom siv hluav taws xob zoo, tsis yog - qhov yuav tsum tau muaj kev nyab xeeb sib tham tau rau ib qho khoom vaj khoom tsev nyob hauv hluav taws xob.
Thaum ua hauj lwm nrog HIPS Granules, nws yog ib qho tseem ceeb los tswj lub txias theem ntawm kev txhaj tshuaj molding kom zoo zoo. Txij li cov khoom muaj pwm shrinkage tsawg, nws tso cai rau kom nruj heev, kom ntseeg tau tias cov nyees khawm thiab thav duab haum ua ke tsis muaj qhov khoob. Cov xov xwm kev lag luam tsis ntev los no qhia txog qhov kev xav tau ntawm cov khoom siv rov ua dua tshiab ntawm cov pellets no, uas tau tsav los ntawm kev txhawb nqa thoob ntiaj teb. Txawm li cas los xij, rau cov nqi hloov pauv, cov khoom siv nkauj xwb tseem nyiam los ua kom cov xim sib xws thiab qhov siab tshaj plaws gloss. Txhawm rau ua tiav cov txiaj ntsig zoo tshaj plaws, cov pwm kub yuav tsum tau khaws cia nyob ib puag ncig 40 txog 60 degrees Celsius, uas yuav pab cov polymer kom khov sai sai thaum tswj hwm qhov xav tau siab - cuam tshuam lub zog.
