I-Warpage deformation ibhekisa ekugqwethekeni kobume benaliti ebunjiweyo yemveliso kunye ne-warpage, itenxa kwiimfuno zokuchaneka kobume benxalenye, yenye yeziphene ukusombulula kuyilo lokungunda inaliti kunye nemveliso.
Yintoni ebangela imiba kunye nendlela yokuphuculayona?
Ubume bokubumba, iimpawu ze-thermophysical zezinto zeplastiki kunye neemeko kunye neeparitha zenkqubo yokubumba zonke zineempembelelo ezahlukeneyo kwi-warpage kunye nokuguqulwa kwemveliso.
1. Iziphene zokungunda
Uyilo lokubumba lumisela ukuthambekela kwe-warpage yenxalenye, kwaye kunzima kakhulu ukucinezela lo mkhuba ngokuguqula iimeko zokubumba, ngoko ke isisombululo sokugqibela kufuneka siqale kuyilo lokubumba kunye nokuphucula.
(1) Ukuphucula i-mold ukwenzela ukuba ubukhulu kunye nomgangatho wecandelo lifane ngakumbi.
(2) uyilo lwenkqubo yokupholisa ukwenza iqondo lobushushu lomngundo lifane kuwo onke amalungu, ukutyeba okufanelekileyo kobunzima bokwenza inxalenye yezinto ezininzi, umjelo omkhulu wokuqukuqela, ukunciphisa umgama wokuqukuqela, kangangoko ukuphelisa Umahluko woxinaniso lomgodi, umahluko woxinzelelo, umahluko wobushushu.
(3) Indawo yotshintsho kunye neekona zobunzima benxalenye kufuneka igudiswe ngokwaneleyo kwaye ibe nokukhululwa kokungunda okulungileyo, njengokwandisa umda wokukhulula, ukuphucula ukukhazimliswa kwendawo yokubumba, ukunciphisa ubukhulu bomaleko onomkhenkce xa ugcwalisa ukubumba. , ukunciphisa uxinzelelo lwangaphakathi kunye nokugcina ukulingana kwenkqubo ye-ejector.
(4) Ukuqinisekisa ukungena komoya okulungileyo.
(5) Ukwandisa ubuninzi bodonga lwenxalenye okanye ukwandise isalathiso sokumelana ne-warp, ngokuqinisa ukuqinisa ukunyusa ukuchasana kwe-warp inxalenye.
2. Ukulawulwa okungafanelekanga kokulungiswa kunye neemeko zokubumba
Kwinkqubo yokubumba inaliti, iplastiki etyhidiweyo kwinqanaba lokuzalisa i-mold mold ngenxa yokucwangciswa kweemolekyuli zepolymer ecaleni kwendlela yokuhamba ukuze iplastiki ihambe kwicala lokuhamba kwereyithi ye-shrinkage kunendlela ethe nkqo yesantya sokushwabana, kunye nenaliti ebunjiweyo. amalungu e-warpage deformation (okt anisotropy).Ngokuqhelekileyo, ukushwabana okufanayo kubangela kuphela utshintsho kumthamo wenxalenye yeplastiki, ukushwabana okungalinganiyo kuphela kuya kubangela ukuguqulwa kwephepha lemfazwe.
Uxinzelelo lwenaliti, ireyithi kunye nezinye iiparamitha zomatshini wokutofa, ukuzaliswa kunye nenqanaba lokupholisa lobushushu, uxinzelelo, isantya sesithathu sidityaniswe kunye, inkqubo yokutofa, umahluko weqondo lobushushu phakathi kwemimandla eyahlukeneyo ebangelwa luxinzelelo lwe-thermal, i-thermal deformation okanye ukushwabana okungalinganiyo okukhokelela kumzuzu wokugoba, kunokwenza ukuba iindawo zeplastiki zibe ne-warpage deformation
(1) Ukunciphisa uxinzelelo lwe-injection kunye nokunciphisa ixesha lokubamba ukuqinisekisa ubushushu obaneleyo bokunyibilika ukuphepha i-warpage ngenxa yokwanda koxinzelelo lwangaphakathi.
(2) Ukunciphisa ukushisa kwesikhunta kunye nokwandisa ixesha lokupholisa ukuphepha ukugqithiswa kwenxalenye ngexesha lokuchithwa kunye ne-ejection deformation.
(3) Ukunciphisa isantya se-screw kunye noxinzelelo lwangasemva ukunciphisa ubuninzi ngelixa ugcina ixabiso elincinci ukunciphisa uxinzelelo lwangaphakathi.
(4) Ukuba kuyimfuneko, ukubumba okuthambileyo okanye ukudilizwa emva kokudilizwa kunokwenziwa kwiindawo ezithambekele kwi-warpage kunye nokuguqulwa.
Xa isitofu sibumba, kuya kubakho iingxaki ezininzi, uXiamen Ruicheng unamava angaphezulu kweminyaka engama-20 kule ndawo, enokunika inkxaso yobugcisa kunye noncedo.Ngaba ungathanda ukwazi ngakumbi?Qhagamshelana nathi ngoku!
