Raw Material Selection: Qhov zais cia ntawm PP Granules
Lub "genesis" ntawm PP khob lub hau yog nyob rau hauv polypropylene (PP) granules -cov thermoplastic resin muaj npe nrov rau nws qhov kub thiab txias thiab tshuaj corrosion, nrog rau nws lub teeb yuag. Cov nroj tsuag ua haujlwm tseem ceeb ntawm kev xaiv zaub mov- qib PP granules; cov ntaub ntawv nyoos no tau txais kev kho tshwj xeeb kom ntseeg tau tias lawv tsis yog - lom, tsis muaj ntxhiab, thiab muaj peev xwm tiv taus qhov kub thiab txias ntawm qhov kub ntawm -20℃txog 120℃. Interestingly, lub khob hau ntawm ntau yam xim tuaj yeem tshwm sim los ntawm cov khoom siv tib yam ntawm cov khoom siv raw- los ntawm kev sib xyaw cov khoom noj-qib xim masterbatches, cov tuam txhab lag luam tuaj yeem siv lub hau tsis muaj xim dawb, dub, lossis txawm tias xim xim xim.
Moulding txheej txheem: Hloov ntawm Granules mus rau lub hau
Txhaj tshuaj molding yog txoj kev tsim khoom tshaj plaws rau PP khob hau. Cov khoom siv raw granules tau rhuab mus rau lub xeev molten- feem ntau ntawm 180℃thiab 230℃-thiab tom qab ntawd txhaj rau hauv lub siab siab rau hauv lub pwm kab noj hniav. Pwm tsim muaj ntau yam kev txawj ntse: qhov tseeb ntawm lub hau ntawm cov ntsia hlau threads yuav tsum tswj tsis pub dhau 0.05 hli; txwv tsis pub, lub hau yuav tsis ruaj ntseg rau lub khob. Tsis tas li ntawd, lub protrusion qhov siab ntawm lub nplhaib sealing yuav tsum tau calibrated mus rau ib qho tseeb 0.2 mm los lav ib tug kiag li leak- pov thawj foob. Ib qho kev tshaj lij tshaj plaws yog ob- xim txhaj tshuaj molding, uas tso cai rau kev tsim ib txhij ntawm lub khob hau ua tiav nrog cov mos- roj hmab sealing nplhaib, yog li tshem tawm qhov xav tau rau cov kauj ruam tom ntej.
Surface Finishing: Zoo nyob hauv cov ntsiab lus
Freshly demolded khob hau tej zaum yuav pom burrs los yog parting kab, yuav tsum tau ib tug peb -theem tiav txheej txheem: ua ntej, neeg hlau caj npab tshem tawm tshaj flash ntawm cov npoo; Tom ntej no, kev ntxuav ultrasonic tshem tawm cov roj seem lossis roj; thiab thaum kawg, lub log polishing ua rau saum npoo zoo li daim iav. Qee qhov siab - kawg lub khob hau muaj qhov ntxiv los tiv thaiv- cov ntaub nplaum nplaum- tsim los ntawm laser engraving rau etch pob zeb diamond-patterned grooves kwv yees li 0.1 mm tob rau hauv qhov chaw- uas txhim kho tuav yam tsis muaj kev cuam tshuam rau kev ncaj ncees ntawm lub foob. Rau kev sib txuas ntxiv ntawm kev muaj tswv yim, pad luam ntawv thev naus laus zis tuaj yeem ua haujlwm los luam cov logos lossis cov qauv ua si rau hauv lub hau, tam sim hloov lub khob lub hau rau hauv cov khoom lag luam nrog tus cwj pwm txawv.
