Yiziphi izinto zokwakha ze-plastic mold cavity?

I-plastic mold cavity material ibhekisela ezintweni ezisetshenziselwa ukwakha ingxenye yesigxobo sesikhunta sepulasitiki.Izibunjwa zepulasitiki ezihlukene zisebenzisa izinto ezihlukene zomgodi ukuze zihlangabezane nezidingo nezidingo ezahlukene.

Okulandelayo yizinto ezi-5 ezijwayelekile zokubunjwa kwepulasitiki:

(1) Insimbi yensimbi: Insimbi yensimbi ingenye yezinto ezisetshenziswa kakhulu isikhunta sepulasitiki.Inobunzima obuhle, ukumelana nokugqoka kanye nokumelana nokugqwala, futhi ingakwazi ukumelana nezinqubo zokubumba umjovo ngaphansi kwezinga lokushisa eliphezulu nezimo zengcindezi ephezulu.Izinsimbi ezivamile zamathuluzi zihlanganisa i-P20 (eyaziwa ngokuthi i-3Cr2Mo e-China), i-718 (eyaziwa ngokuthi i-3Cr2NiMo e-China) njalonjalo.

(2) Insimbi engagqwali: Insimbi engagqwali ingenye into evame ukusetshenziswa esikhunjeni sepulasitiki.Insimbi engagqwali inokumelana nokugqwala okuphezulu kanye nokumelana ne-oxidation, elungele ukwelapha izinto zepulasitiki ezinezithako ezine-asidi noma ezine-alkali.Izinto ezijwayelekile zensimbi engagqwali yi-SUS420, SUS304 njalonjalo.

(3) I-aluminium alloy material: I-aluminium alloy iyimpahla engasindi futhi enhle yokushisa eshisayo, ifanele ukukhiqiza isikhunta esikhulu noma isikhunta esinezidingo zesisindo esincane.Ama-alloys e-aluminium ane-conductivity ephezulu yokushisa, esiza ukusheshisa ukupholisa amapulasitiki.Izinto ezijwayelekile ze-aluminium alloy yi-ADC12, 6061 nokunye.

(4) I-copper alloy material: I-alloy ye-Copper ine-conductivity enhle yokushisa kanye nokumelana nokugqoka, ifanele ukukhiqiza isikhunta ngaphansi kokushisa okuphezulu nezimo zengcindezi ephezulu.Ama-alloys ethusi angahlinzeka ngokukhipha ukushisa okungcono futhi asize ukulawula izinga lokupholisa lamapulasitiki.Izinto ezivamile ze-copper alloy ziyi-H13, CuBe2 njalonjalo.

5Isibonelo, i-polyimide (PI), i-polytetrafluoroethylene (PTFE) nezinye zinezinga lokushisa eliphakeme kakhulu lokumelana nokumelana nokugqwala, ezifanele ukwelashwa kwamapulasitiki okushisa aphezulu noma izinto ezikhethekile zepulasitiki.

Kuyadingeka ukukhetha okufaneleisikhunta sepulasitikiimpahla yesikhala ngokuya ngezidingo ezithile zohlelo lokusebenza kanye nezici zezinto zepulasitiki.Izinto ezihlukene zinezici ezihlukene kanye nobubanzi bokusebenza, emikhiqizweni ehlukene yomjovo kanye nezidingo zokukhiqiza, ukukhetha impahla ye-cavity efanele kuyisici esibalulekile sokuqinisekisa ukusebenza kwesikhunta nokuphila.
