M'magulu amakono a mafakitale, zinthu zapulasitiki ndizofala kwambiri.Zatsopano zambiri zimapangidwa ndi pulasitiki, ndipo pulasitiki yamtundu uliwonse imapangidwa ndi nkhungu.Kupanga nkhungu za pulasitiki nthawi zambiri kumatha kugawidwa m'magawo asanu akuluakulu.

1) Kusanthula kwa zigawo zapulasitiki

Pamapangidwe a nkhungu, akatswiri opanga nkhungu apulasitiki ayenera kusanthula bwino ndikuphunzira ngati zigawo za pulasitiki zikukwaniritsa zofunikira pakuwumba, kuphatikiza kukambirana za mawonekedwe a geometric, kulondola kwake komanso mawonekedwe azinthuzo.Yesetsani kupewa zovuta zosafunikira pakupanga nkhungu ndi kupanga pulasitiki.

2) Pulasitiki nkhungu kapangidwe kapangidwe

Chikombole chabwino sichimangofunika zida zabwino zogwirira ntchito komanso ogwira ntchito odziwa kupanga nkhungu, komanso zimafunikanso mapangidwe abwino a pulasitiki, makamaka pamapangidwe ovuta.Ubwino wa mapangidwe a nkhungu umaposa 80% ya mtundu wa nkhungu.Wopanga nkhungu wabwino amayenera kuchepetsa ndalama zopangira makina ndikuchepetsa zovuta zopanga ndikufupikitsa nthawi yopanga nkhungu ya pulasitiki potengera zomwe makasitomala amafuna.Chikombole choyenerera bwino chiyenera kukhala chosavuta kupanga ndi kukonza mtsogolo.

3) Dziwani zachitsulo ndi muyezo wa zigawo za nkhungu

Potumiza kunja nkhungu jekeseni pulasitiki, pali muyezo osiyana makasitomala.Malinga ndi zomwe Suntime adakumana nazo pakugwira ntchito ndi msika wapadziko lonse lapansi, pali muyezo wa DFM, muyezo wa Hasco, muyezo wa LKM ndi zina zotero.Posankha zigawo pulasitiki nkhungu, tiyenera kuphunzira muyezo makasitomala 'ndi specifications choyamba, ndi kufupikitsa nkhungu kupanga kutsogolera nthawi, kusankha zigawo zikuluzikulu kuti makina adzakhala bwino.Posankha zitsulo za nkhungu, kuwonjezera pa kulingalira kulondola ndi khalidwe la mankhwala, kusankha koyenera kuyeneranso kupangidwa pamodzi ndi makina opangira mafakitale a nkhungu ndi mphamvu zenizeni zothandizira kutentha.

4) Nkhungu zigawo Machining ndi nkhungu msonkhano

Kulondola komanso mtundu wa nkhungu yojambulira pulasitiki sikungotsimikiziridwa ndi kapangidwe koyenera ka nkhungu & kapangidwe ka nkhungu ndi kukula kwake kolondola, komanso kumakhudzidwa ndi zida zamakina zamakina ndi msonkhano wa nkhungu & kuyika koyenera.

Choncho, kusankha nkhungu kupanga processing n'kofunika kwambiri, zimakhudza kwambiri kulondola kwa zigawo & amaika, njira processing ali ndi udindo wofunika kwambiri mu kupanga nkhungu pulasitiki.

5) Mayesero a Nkhungu

Kuyesa nkhungu ndi gawo lofunikira kuti muwone ngati nkhungu ya pulasitiki ndiyoyenerera kapena ayi.Pa ndondomeko, mukhoza kuyesa ndi kusankha bwino akamaumba chizindikiro tsogolo yosalala kupanga mankhwala pulasitiki.Mayesero a nkhungu amatha kutsimikizira ngati kuumba kukuyenda bwino kapena ayi, momwe kuzirala kulili, komanso kukula kwa chipata, malo ndi mawonekedwe ake zimakhudza kulondola ndi maonekedwe a mankhwala.Nthawi zambiri, kuyesa koyamba (T1) sikungakhale kwangwiro, chifukwa chake pambuyo poyesa nkhungu, tiyenera kupanga lipoti ndikupanga yankho lazowongolera & kusinthidwa ndikuchita T2, T3 .. mpaka magawo akhale abwino.Mu Suntime Mould, nthawi zambiri timayesa kuyesa nkhungu mkati mwa nthawi za 3.
