Kev txhaj tshuaj molding tshuab tuaj yeem tsim tag nrho cov khoom yas.Tab sis ntau hom yas yuav tsum tau nruab nrog cov tshuab txhaj tshuaj sib txawv.
Kev xaiv cov tshuab txhaj tshuaj molding yuav tsum ua ke nrog cov yam ntxwv ntawm cov yas. Qhov sib txawv ntawm cov ntsiab lus melting, viscosities, thiab molding mechanisms.Yog li, ntau hom yas muaj cov kev xav tau sib txawv rau cov plasticizing, txhaj tshuaj, clamping, thiab pab pawg ntawm cov tshuab txhaj tshuaj molding. Cov kev ntsuam xyuas hauv qab no tsom mus rau peb lub ntsiab plastics: cov khoom siv thermoplastic dav dav, engineering plastics, thiab thermosetting plastics.
1. General Thermoplastic Plastics (piv txwv li, PE, PP)
Cov yas thermoplastic dav dav muaj cov ntsiab lus melting tsawg (150-250 degree), zoo fluidity, thiab tsawg molding nyuaj. Lawv cov kev cai rau kev txhaj tshuaj molding tshuab yog ua raws li cov haujlwm yooj yim, tsis tas yuav tsum muaj cov txheej txheem nyuaj.
2. Engineering Plastics (piv txwv li, PC, PA)
Engineering plastics muaj cov yam ntxwv ntawm lub zog siab, siab kub tsis kam, thiab siab viscosity. Lawv feem ntau siv nyob rau hauv precision structural qhov chaw xws li nws pib qhov chaw thiab hluav taws xob casings, thiab muaj nruj kev cai ntawm kev ua tau zoo ntawm kev txhaj tshuaj molding tshuab.
3. Thermosetting Plastics (xws li, Phenolic Resin, Epoxy Resin)
Thermosetting Plastics yuav tshwm sim chemical cross-kev sib txuas cov tshuaj tiv thaiv thaum lawv molded, los ntawm ib lub xeev yas mus rau ib tug insoluble thiab infusible khoom.Lub molding mechanism yog tshwj xeeb, thiab lawv muaj tej yam kev cai rau cov qauv thiab txheej txheem ntawm txhaj tshuaj molding tshuab.
Tag nrho txhua yam, txhua tus tswv lub Hoobkas yuav tsum ua raws li cov yam ntxwv ntawm cov yas thaum xaiv cov tshuab txhaj tshuaj molding.
