Xaiv cov yas yas zoo rau koj qhov project molding tuaj yeem yog qhov nyuaj.Tus nqi, qhov ntom ntom, yoog raws, lub zog, thiab ntau dua txhua yam ua rau cov resin zoo tshaj plaws rau koj txoj haujlwm.
Ntawm no yog ib qho kev qhia txog cov yam ntxwv, cov txiaj ntsig, thiab qhov tsis zoo rau cov resins feem ntau siv hauv tshuab moulding.
High Density Polyethylene (HDPE)
HDPE yog lub ntiaj teb # 1 yas thiab feem ntau tshuab molded yas khoom.Nws yog siv nyob rau hauv ib tug loj array ntawm cov khoom, nrog rau cov fwj rau cov neeg siv cov kua xws li tshuaj zawv plaub hau thiab lub cev muaj zog roj, coolers, ua si lug, roj tso tsheb hlau luam, industrial nruas, thiab nqa cov ntaub ntawv.Nws yog molder-phooj ywg, translucent thiab yooj yim xim, thiab chemically inert (FDA pom zoo thiab tej zaum qhov zoo tshaj plaws ntawm tag nrho cov yas).PE cov khoom siv feem ntau siv dua tshiab nrog cov qauv siv rov ua dua tshiab 2.
