Yiziphi izidingo ekukhethweni kwezinto zokwakha umjovo?

Ukukhethwa kwempahla yeimijovo isikhuntainquma ngokuqondile ikhwalithi yesikhunta, ngakho-ke yiziphi izidingo eziyisisekelo ekukhethweni kwezinto zokwakha?

1) Ukusebenza okuhle kokucubungula komshini

Ukukhiqizwa kwezingxenye zokubunjwa komjovo, eziningi zazo eziqedwa ngokucubungula ngomshini. Ukusebenza okuhle kokucubungula komshini kuyadingeka ukuze kuzuzwe ukucubungula ngesivinini esikhulu. Ingakwazi ukunweba impilo yethuluzi lokucubungula, ithuthukise ukusebenza kahle kokusika, inciphise ukuhwaqazeka kwendawo, ukuze ithole izingxenye zesikhunta ezinembayo.

2) Ubulukhuni obanele bobuso nokumelana nokugqoka

Ubulukhuni obungaphezulu kanye nokunemba kobukhulu bemikhiqizo yepulasitiki kanye nempilo yesevisi yesikhunta somjovo kuhlobene ngokuqondile nobulukhuni, ubulukhuni kanye nokumelana nokugqokwa kobuso besikhunta somjovo. Ngakho-ke, kuyadingeka ukuthi indawo yokubumba yesikhunta sokujova ibe nobunzima obanele, futhi ubulukhuni bayo bokucisha akufanele bube ngaphansi kwe-55 HRC, ukuze kutholwe ukumelana nokugqoka okuphezulu futhi kunwebe impilo yesevisi yesikhunta.

3) Amandla anele nokuqina

Ngenxa yokuthi isikhunta somjovo sibhekene ngokuphindaphindiwe namandla okugoqa kanye nokucindezelwa komjovo we-mold cavity enqubweni yokubumba, ikakhulukazi isikhunta sokujova esinobukhulu obuphakathi nendawo futhi esiyinkimbinkimbi, izingxenye zesikhunta kufanele zibe namandla aphezulu kanye nokuqina okuhle ukuhlangabezana izidingo zokusetshenziswa.

4) Yiba nokusebenza okuhle kokupholisha

Ukuze kutholwe indawo ephezulu ecwebezelayo yemikhiqizo yepulasitiki, ubulukhuni obungaphezulu bezingxenye ezibunjiwe budingeka bube buncane, ngaleyo ndlela budinge ingaphezulu lezingxenye ezibunjiwe ukuthi lipholishwe ukuze kuncishiswe ukuhwaqazeka kwendawo. Ukuqinisekisa ukucwebezelisa, okokusebenza okukhethiwe akumele kube namaphutha njengokungcola okumaholoholo.

5) Yiba nenqubo yokwelapha ukushisa okuhle

Izinto zokubumba zivame ukuthembela ekwelapheni ukushisa ukuze kuzuzwe ubulukhuni obudingekayo, obudinga ukuqina okuhle kwezinto. Plastic umjovo isikhunta izingxenye ngokuvamile ijamo eziyinkimbinkimbi, ukucisha ukucubungula kunzima kakhulu, noma ngisho nje ayikwazi ukucutshungulwa, ngakho izingxenye isikhunta kufanele sizame ukukhetha ukushisa ukwelashwa deformation izinto ezincane, ukuze kuncishiswe inani processing ngemva kokwelashwa ukushisa. .

6) Ukumelana nokugqwala okuhle

Amanye amapulasitiki nezithasiselo zawo ekubumbeni azokhiqiza amagesi agqwalayo, ngakho-ke ukukhetha kwezinto zokubumba umjovo kufanele kube nezinga elithile lokumelana nokugqwala. Ngaphezu kwalokho, i-nickel, i-chromium nezinye izindlela zingasetshenziswa ukuthuthukisa ukumelana nokugqwala kwendawo yesikhunta.

I-7) Ukusebenza okuhle kokucubungula okuphezulu

Imikhiqizo yepulasitiki idinga ukubukeka okuhle.Umhlobiso wephethini udinga iphethini yokuqopha amakhemikhali ebusweni bomgodi wokubunjwa, ngakho-ke impahla yokubumba iyadingeka ukuze ikhiphe iphethini kalula, iphethini icace, ingagugi.
