Ukuqina kodonga lweizingxenye zepulasitikiinethonya elikhulu izinga. Lapho ubukhulu bodonga buncane kakhulu, ukumelana nokugeleza kuphezulu, futhi kunzima ezingxenyeni zepulasitiki ezinkulu neziyinkimbinkimbi ukugcwalisa umgodi. Ubukhulu bodonga lwezingxenye zepulasitiki kufanele buhlangabezane nezidingo ezilandelayo:
1. Yiba namandla anele kanye nokuqina;
2. Ingakwazi ukumelana nomthelela kanye nokudlidliza kwendlela yokudiliza lapho idilizwa;
3. Ingakwazi ukumelana namandla okuqinisa ngesikhathi sokuhlanganisa.
Uma isici sokuqina kodonga singacatshangelwa kahle esigabeni sokuklama sezingxenye ezibunjiwe zomjovo, kuzoba nezinkinga ezinkulu kamuva emkhiqizweni.
Lesi sihloko sigxile ekwenziweni kwezingxenye ezibunjwe ngomjovo we-thermoplastic, kucatshangelwa umphumela wengxenye yodonga ngesikhathi somjikelezo, ukuncipha komkhiqizo kanye ne-warpage, kanye nekhwalithi yangaphezulu.
Ukwanda kokuqina kwezindonga kuholela ekwandeni kwesikhathi somjikelezo
Izingxenye zepulasitiki ezibunjwe ngomjovo kufanele zipholiswe ngokwanele ngaphambi kokuba zikhishwe esikhunjeni ukuze kugwenywe ukuwohloka komkhiqizo ngenxa yokukhishwa. Izingxenye eziwugqinsi zezingxenye zepulasitiki zidinga izikhathi zokupholisa ezinde ngenxa yamazinga aphansi okudlulisa ukushisa, okudinga isikhathi esengeziwe sokuhlala.
Ngokombono, isikhathi sokupholisa sengxenye ebunjiwe yomjovo silingana nesikwele sokuqina kodonga engxenyeni ewugqinsi kakhulu yengxenye. Ngakho-ke, ukujiya kodonga lwengxenye enkulu kuzonweba umjikelezo womjovo, kunciphise inani lezingxenye ezikhiqizwa ngesikhathi seyunithi, futhi kwandise izindleko ingxenye ngayinye.
Izingxenye eziwugqinsi zijwayele ukungqubuzana
Ngesikhathi sokubumba umjovo, kanye nokupholisa, ukuncipha kwezingxenye ezibunjiwe zomjovo kuzokwenzeka nakanjani. Inani lokuncipha komkhiqizo lihlobene ngokuqondile nokuqina kodonga lomkhiqizo. Okusho ukuthi, lapho ubukhulu bodonga bukhulu, ukuncipha kuzoba kukhulu; lapho ubukhulu bodonga buncane, ukuncipha kuzoba kuncane. I-warpage yezingxenye ezibunjiwe zomjovo ngokuvamile ibangelwa amanani ahlukene okuncipha ezindaweni ezimbili.
Izingxenye ezacile, ezifanayo zithuthukisa izinga eliphezulu
Inhlanganisela yezingxenye ezacile neziwugqinsi ijwayele ukuba nemiphumela yomjaho ngoba inyibiliko igeleza ngokushesha eduze kwengxenye ewugqinsi. Umthelela womjaho ungakha amaphakethe omoya kanye nemigqa yokushisela phezu kwengxenye, okuholela ekubukekeni komkhiqizo okungekuhle. Ngaphezu kwalokho, izingxenye eziwugqinsi nazo zivame ukuba nama-dents kanye nama-voids ngaphandle kwesikhathi esanele sokuhlala nokucindezela.
Yehlisa ukujiya kwengxenye
Ukuze unciphise izikhathi zomjikelezo, kuthuthukiswe ukuzinza kwe-dimensional, futhi kuqedwe ukonakala kwendawo, umthetho oyisisekelo wesithupha womklamo wokujiya kwengxenye uwukugcina ugqinsi lwengxenye luzacile futhi lufana ngangokunokwenzeka. Ukusetshenziswa kwama-stiffener kuyindlela ephumelelayo yokufeza ukuqina namandla adingekayo ngenkathi ugwema imikhiqizo eminyene ngokweqile.
Ngaphezu kwalokhu, izilinganiso zengxenye kufanele futhi zicabangele izakhiwo ezibonakalayo zepulasitiki esetshenzisiwe, uhlobo lomthwalo nezimo zokusebenza ingxenye ezobhekana nazo; kanye nezidingo zokugcina zomhlangano nazo kufanele zicatshangelwe.
Okungenhla ukwabelana okuthile kokuqina kodonga lwezingxenye ezibunjiwe zomjovo.
