Njengamanje, izinsimbi ezingenayo insimbi zihlala zigxile kakhulu.

I-surface finish iqhathaniswa kanjani nezinye izindlela?

Ukulingisa okuqinile kancane kuvamise ukukhiqiza isiphetho esisezingeni eliphezulu uma kuqhathaniswa nokusakaza okujwayelekile kwe-die. Ukugeleza kwe-laminar kuvimbela izimpawu zokudumazeka kwendawo, futhi izinga lokushisa lomjovo eliphansi linciphisa ukusoda edayilini. Lokhu kuvame ukuphumela endaweni ebushelelezi njenge-cast, kunciphisa izidingo zokupholisha.

Amathrendi Esikhathi esizayo ku-Semi Solid Technology

Indawo ye i-semi solid metal casting iyaqhubeka nokuthuthuka ngokuthuthuka kwezobuchwepheshe. Ukuhlanganiswa nezimiso ze-Industrial 4.0 kunika amandla ukuqapha kwesikhathi sangempela nokulawula okuguquguqukayo kwenqubo yokulingisa.

Intuthuko ku i-rheocasting eqondile banciphisa ukuthembela kumabhilidi abizayo asakazwa ngaphambili, okwenza inqubo ifinyeleleke kalula kuhlu olubanzi lwezisekelo. Ukuqanjwa kwemiklamo ye-screw-barrel kanye namandla omjovo kuqhubezela ukwandisa imvilophu yamajometri afinyelelekayo nokuqina kwezindonga.

Abashayeli bokusimama cishe bazosheshisa ukutholwa. Njengoba izimboni ziphusha ukuthola izingxenye ezilula, ezinamandla, neziphinde zigaywe kabusha, ukusebenza kahle okungokwemvelo kokucubungula okuqinile kuhambisana kahle nezinjongo zokukhiqiza zesikhathi esizayo. Amandla okucubungula ama-slurries e-high-solid-fraction angase avule amakilasi amasha ama-alloys asebenza kahle kakhulu.

Isiphetho kanye Nezincomo Zesu

Ukulinganisa kwensimbi okuqinile imelela intuthuko ebalulekile ekwenzeni insimbi, enikeza isixazululo esiphoqelelayo sonjiniyela abadinga ukulinganisela ijometri eyinkimbinkimbi nobuqotho obuphezulu besakhiwo. Ngokusebenzisa izici ezihlukile zesimo esiqinile, abakhiqizi bangakhiqiza izingxenye ezidlula ukulingisa kwendabuko ngamandla, ukuvuza okuqinile, nokungaguquguquki.

Lobu buchwepheshe bufaneleka kahle:

• Onjiniyela bezimoto efuna ukunciphisa isisindo semoto ngenkathi igcina ukuphahlazeka.
• Abaklami be-Aerospace edinga izingxenye ezinokwethenjelwa okuphezulu ezinezici zangaphakathi eziyinkimbinkimbi.
• Abathuthukisi bomkhiqizo kuma-electronics adinga ukuvaleka okuqinile, okunezindonga ezincane ezinemiphetho ye-premium.

Ezinhlanganweni ezicubungula lolu shintsho, isinyathelo esilandelayo sibandakanya ucwaningo oluningiliziwe lokungenzeka lwemiklamo yamanje yezingxenye. Ukuhlola amandla okuhlanganiswa kwengxenye nokwehliswa komshini kungaveza amathuba abalulekile okonga. Ukusebenzelana nozakwethu abanolwazi abasebenza ngokukhethekile ekucubunguleni okuqinile kanye nokwenza kahle kuzoqinisekisa ukusetshenziswa okushelelayo futhi kwandise izinzuzo zobuchwepheshe zale ndlela yokukhiqiza eyinkimbinkimbi.
