Ukubumba isitofu kwaziwa ngokuvelisa imiqulu ephezulu yamalungu anyamezelayo.Yintoni abanokuthi abayiqondi abaqulunqi bezonyango, nangona kunjalo, kukuba abanye abavelisi bekhontrakthi banokubiza ngokufanelekileyo iisampulu ezisebenzayo zovavanyo kunye novavanyo.Nokuba yeyezixhobo ezisetyenziswa kanye, izixhobo ezisetyenziswa ngokuphindaphindiweyo okanye izixhobo zonyango ezomeleleyo, ukubumba inaliti yeplastiki yinkqubo eguquguqukayo enokukunceda uzise iimveliso ngokukhawuleza.
Njengayo nayiphi na inkqubo yokuvelisa, kukho iindlela ezifanelekileyo zokubumba inaliti.Ziwela kwiinkalo ezine eziphambili: uyilo lwenxalenye, ukukhetha izinto eziphathekayo, izixhobo kunye nokuqinisekiswa komgangatho.
Ngokuqwalasela oko kusebenza kakuhle kunye nokusebenza ngokusondeleyo nomenzi onamava, unokuphepha iimpazamo eziqhelekileyo ezibangela iindleko ezongezelelweyo kunye nokulibaziseka.La macandelo alandelayo achaza ukuba ngaba abayili bezonyango kufuneka baqwalasele xa bekhupha iprojekthi yokubumba inaliti.
Uyilo lwenxalenye
Uyilo lokwenziwa kwezinto (DFM) yinkqubo yokuyila iinxalenye ukuze kube lula ukwenziwa.Amalungu anonyamezelo olukhululekileyo aneenguqu ezinkulu zobukhulu becala ukuya kwenxalenye kwaye zidla ngokuba lula kwaye zingabizi kakhulu ukwenza.Nangona kunjalo, uninzi lwezicelo zonyango lufuna unyamezelo olungqongqo olusetyenziswa kunye neemveliso zorhwebo.Ke ngoko, ngexesha lenkqubo yoyilo lwenxalenye, kubalulekile ukusebenzisana neqabane lakho lokuvelisa kwaye wongeze uhlobo oluchanekileyo lwentengiso okanye ukunyamezela okuchanekileyo kwimizobo yakho.
Akukho lunye uhlobo lonyamezelo lwesitofu sokubumba, kwaye ukushiya iinkcukacha zomzobo kunokukhokelela kwiindawo ezingahambelani ngokuchanekileyo okanye iindleko ezininzi zokuvelisa.Ukongeza kwi-dimensional tolerances, cinga ukuba ngaba ufuna ukucacisa ukunyamezela ngokuthe tye / ukuthamba, i-diameter yomngxuma, ubunzulu bomngxuma oyimfama kunye noconcentricity / ovality.Ngeendibano zonyango, sebenza kunye neqabane lakho elenza izinto ukuze ubone ukuba onke amalungu adibana njani kwinto eyaziwa ngokuba kukunyamezelana.
Ukukhetha izinto eziphathekayo
Ukunyamezela kuyahluka ngokwezinto eziphathekayo, ngoko musa nje ukuvavanya iiplastiki ngokusekelwe kwiipropati kunye namaxabiso.Ukhetho luluhlu olubanzi ukusuka kwiiplastiki zempahla ukuya kwii-resin zobunjineli, kodwa ezi zixhobo zonke zinento ebalulekileyo efanayo.Ngokungafaniyo noshicilelo lwe-3D, ukubumba inaliti kunokuvelisa iinxalenye ezineempawu ezichanekileyo zokusetyenziswa kokuphela.Ukuba uyila iiprototypes zokulinga, qaphela ukuba unakho ukuguquguquka kokusebenzisa imathiriyeli efanayo nakwimveliso.Ukuba ufuna iplastiki ehambelana nomgangatho othile, cinga ngokucela isatifikethi soqinisekiso (COA) ukuqinisekisa ukuba izinto zokubumba inaliti - kungekhona nje izithako zayo ezizimeleyo - ziyahambelana.
izixhobo
Abavelisi ubukhulu becala benza iinaliti zokubumba ngealuminiyam okanye intsimbi.Izixhobo zeAluminiyam zixabisa kancinci kodwa azikwazi ukuhambelana nenkxaso yesixhobo sentsimbi kwimithamo ephezulu kunye nokuchaneka.Nangona ixabiso lokungunda intsimbi lingathatha ixesha elide ukuba amortize, intsimbi ingabizi kakhulu kumthamo ophezulu wamalungu.Umzekelo, ukuba i-10,000 yeedola yokungunda yentsimbi yemveliso yonyango esetyenziswa kanye ihlawulwe nge-100,000 yezahlulo, ixabiso lesixhobo li-10 leesenti inxalenye nganye.
Isixhobo sentsimbi sinokuba lolona khetho lufanelekileyo kwiiprototypes kunye nemithamo esezantsi, kuxhomekeke kubuchule bakho besibumbi.Ngeyunithi yokufa yenkosi kunye nesakhelo esibandakanya i-sprues kunye nabagijimi, izikhonkwane zenkokeli, imigca yamanzi kunye nezikhonkwane ze-ejector, uhlawula kuphela i-mold cavity kunye neenkcukacha eziphambili.Ukungunda kosapho okuqulathe ngaphezulu komngxuma omnye kunokunciphisa iindleko zesixhobo ngokuba noyilo oluninzi olwahlukileyo ngaphakathi kokungunda okufanayo.
Ukuqinisekisa umgangatho
Ngokubumba inaliti yezonyango, akwanelanga ukuvelisa iindawo ezilungileyo ixesha elininzi kwaye emva koko ube nesebe le-QA libambe naziphi na iziphene.Ukongeza kukunyamezelana okuqinileyo, iinxalenye zonyango zifuna iqondo eliphezulu lokuchaneka.I-DFM, iisampulu ze-T1 kunye novavanyo lwasemva kokuveliswa kunye nokuhlolwa zibalulekile, kodwa ulawulo lwenkqubo lubalulekile kwizinto eziguquguqukayo ezifana namaqondo obushushu, amazinga okuhamba kunye noxinzelelo.Ke kunye nesixhobo esifanelekileyo, isibumbi sakho senaliti yezonyango kufuneka sikwazi ukuchonga iimpawu ezibaluleke kakhulu-kuya-kumgangatho (CTQ).
Izinto ezilahlwayo, izixhobo zonyango ezisetyenziswa ngokuphindaphindiweyo kunye nezixhobo zonyango ezomeleleyo, ukubumba inaliti kunokukunceda uzise iimveliso kwintengiso ngokukhawuleza emva kokuba iprototyping yealpha kunye ne-beta igqityiwe.Ukubumba i-injection kuyaziwa ngokuxhasa ukuveliswa kwevolumu ephezulu, kodwa i-pilot prototyping yexabiso elisebenzayo nayo inokwenzeka.Izitofu zokubumba zinesakhono esahlukileyo, ngoko ke cinga ngokwenza ukhetho lomthengisi ngononophelo lolona qheliselo lulungileyo lweprojekthi yakho elandelayo.
