Chifukwa chomwe kupanga zinthu zapulasitiki nthawi imodzi kumakhala kothandiza kwambiri pazinthu zapulasitiki za OEM

Kupanga zinthu zapulasitiki kamodzi kokha kumakhala kothandiza kwambiri chifukwa kumachotsa ulalo wofooka kwambiri m'mapulojekiti ambiri ogulitsa: udindo wogawanika. Pamene kapangidwe, kupanga nkhungu, kupanga jekeseni, ndi kukonza pambuyo pake zikugawidwa pakati pa ogulitsa, kugawa kulikonse kumabweretsa chiopsezo cha kusagwirizana mu geometry, kusankha zinthu, kumaliza pamwamba, kapena nthawi.

Momwe kapangidwe ka nkhungu ka jakisoni wa pulasitiki kamathandizira kupanga bwino

Kapangidwe ka nkhungu ndi chinthu chofunikira kwambiri pakupanga ngati gawo lingapangidwe mokhazikika pamlingo. Pakupanga zinthu zapulasitiki, nkhungu si chida chopangira zinthu zokha; ndi njira yolondola yomwe imayang'anira kudzaza, kuziziritsa, kutulutsa, ndi kukhazikika kwa gawo lomaliza. Ngati malo olowera ali olakwika, gawolo lingapindike. Ngati kuziziritsa sikuli kofanana, nthawi yozungulira imakwera ndipo kuchepa kwake kumakhala kosagwirizana. Ngati mpweya wotuluka suli wokwanira, zizindikiro za kutentha kapena kuwombera kwakanthawi kungawonekere.

Pa nyumba ndi zinthu zina zomangira, kapangidwe ka nkhungu kayenera kulinganiza mawonekedwe ndi mphamvu. Zipangizo zamagetsi ndi zida zamagetsi nthawi zambiri zimafuna mizere yoyera yolekanitsira, makulidwe ofanana a khoma, komanso mawonekedwe okhazikika olumikizirana.nkhungu ya nyumba ya pulasitikinthawi zambiri akuyembekezeka kuthandizira ubwino wa zokongoletsa komanso kulondola kwa kusonkhana, zomwe zikutanthauza kuti ma ngodya ozungulira, nthiti, mabowo, ndi malo oyika ejector zonse ziyenera kukonzedwa pamodzi.

Maonekedwe ovuta amawonjezera gawo lina.Yankho la nkhungu la 3DKawirikawiri imagwiritsidwa ntchito ngati chinthucho chili ndi kupindika, kudulidwa pang'ono, kapena mawonekedwe osiyana. Pazochitika izi, nkhungu iyenera kusunga cholinga cha kapangidwe kake pomwe ikulolabe kuchotsedwa ndi kupanga kokhazikika. Ichi ndi chimodzi mwa zifukwa zomwe kuwunika kwa DFM musanagwiritse ntchito zida kuli kofunikira kwambiri: kumatha kuwulula ngati chinthucho chingathe kupangidwadi monga momwe chajambulidwa.
