I-warpage deformation ingenye yezinkinga ezivamile ekubunjweni komjovo wezingxenye zepulasitiki zegobolondo elincanyana.Iningi lokuhlaziywa kwe-warpage deformation lisebenzisa ukuhlaziywa kwekhwalithi, futhi izinyathelo zithathwa ezicini zokwakheka komkhiqizo, ukwakheka kwesikhunta kanye nezimo zenqubo yokubumba umjovo ukuze kugwenywe ukuwohloka okukhulu kwamakhasi e-warpage ngangokunokwenzeka.Ngokwesibonelo, eminye imikhiqizo yepulasitiki evamile,ama-racks epulasitiki ezicathulo, iziqeshana zepulasitiki, amabakaki epulasitiki, njll
Ngokuphathelene nesikhunta, isikhundla, ifomu kanye nenani lamasango esikhunta somjovo kuzothinta isimo sokugcwalisa ipulasitiki emgodini wesikhunta, okuholela ekuguqulweni kwezingxenye zepulasitiki.Njengoba ukuwohloka kwekhasi le-warpage kuhlobene nokuncipha kokungalingani, ubudlelwano phakathi kokuncipha kanye ne-warpage yomkhiqizo buyahlaziywa ngokutadisha ukuziphatha kokuncipha kwamapulasitiki ahlukene ngaphansi kwezimo zezinqubo ezihlukene.Kuhlanganisa umthelela wokucindezelwa okushisayo okusele ekuwohlokeni kwekhasi le-warpage lemikhiqizo, kanye nomthelela wesiteji se-plasticization, ukugcwaliswa kwesikhunta kanye nesiteji sokupholisa kanye nesiteji sokudiliza ekuwohlokeni kwekhasi le-warpage lemikhiqizo.
Umthelela wokuncipha kwemikhiqizo ebunjiwe yomjovo kusixazululo se-warping deformation:
Imbangela eqondile yokuwohloka kwekhasi le-warpage lemikhiqizo ebunjiwe yomjovo ilele ekuncipheni okungalingani kwezingxenye zepulasitiki.Ukuhlaziywa kwe-warpage, ukuncipha ngokwako akubalulekile.Okubalulekile umehluko ekuncipheni.Enqubweni yokubunjwa komjovo, ngenxa yokuhlelwa kwama-molecule e-polymer eduze nendawo yokugeleza, ukushwabana kwamapulasitiki ancibilikisiwe lapho kugeleza khona kukhulu kunalokho okuqonde mpo, okuholela ekwakhiweni kwe-warpage nokuwohloka kwezingxenye zomjovo.Ngokuvamile, ukuncipha komfaniswano kubangela kuphela izinguquko kumthamo wezingxenye zepulasitiki, futhi ukuncipha okungalingani kuphela okungabangela ukuwohloka kwamakhasi e-warpage.Umehluko phakathi kwezinga lokushwabana kwamapulasitiki acwebile endleleni yokugeleza kanye nesiqondiso esiqondile mkhulu kunalelo lamapulasitiki a-amorphous, futhi izinga lawo lokushwabana nalo likhulu kunalelo lamapulasitiki angama-amorphous.Ngemuva kokuphakama kwenani elikhulu lokushwabana kwamapulasitiki acwebile kanye ne-anisotropy of shrinkage, ukuthambekela kokuwohloka kwe-warping of crystalline deformation kukhulu kakhulu kunaleyo yamapulasitiki a-amorphous.
Inqubo yokubumba umjovo we-Multistage ekhethiwe ngokusekelwe ekuhlaziyweni kwejometri yomkhiqizo: ngenxa yomgodi ojulile nodonga oluncane lomkhiqizo, isikhunta sesikhunta singumzila omude futhi omncane.Lapho ukuncibilika kugeleza kule ngxenye, kufanele kudlule ngokushesha, ngaphandle kwalokho kulula ukupholisa nokuqinisa, okuzoholela engozini yokugcwalisa isikhunta sesikhunta.Umjovo wesivinini esiphezulu kufanele usethwe lapha.Kodwa-ke, umjovo wesivinini esikhulu uzoletha amandla amaningi e-kinetic ekuncibilikeni.Lapho ukuncibilika kugeleza phansi, kuzokhiqiza umthelela omkhulu we-inertial, okuholela ekulahlekelweni kwamandla kanye nokuchichima konqenqema.Ngalesi sikhathi, kuyadingeka ukunciphisa izinga lokugeleza kokuncibilika futhi unciphise ingcindezi yokugcwalisa isikhunta, futhi ugcine ingcindezi eyaziwayo ebamba ingcindezi (ingcindezi yesibili, ingcindezi yokulandelela) ukwenza ukuncibilika kwengeze ukuncipha kokuncibilika. ungene emgodini wesikhunta ngaphambi kokuba isango liqine, okubeka phambili izidingo zejubane lomjovo wezigaba eziningi kanye nengcindezi yenqubo yomjovo.
Isixazululo se-warpage kanye nokuwohloka kwemikhiqizo okubangelwa ukucindezelwa kokushisa okusele:
Isivinini se-fluid surface kufanele sibe njalo.Umjovo weglue osheshayo uzosetshenziswa ukuze kunqandwe ukuncibilika ekuqineni ngesikhathi sokujova ngeglue.Ukulungiselelwa kwejubane lomjovo weglue kufanele kucabangele ukugcwaliswa okusheshayo endaweni ebucayi (njengesiteshi sokugeleza) nokunciphisa endaweni yokungena kwamanzi.Ijubane lomjovo weglue kufanele liqinisekise ukuthi liyama ngokushesha ngemva kokuba isikhunta sesigcwaliswe ukuvimbela ukugcwaliswa ngokweqile, i-flash kanye nokucindezeleka okusalayo.
