Izimbangela nezixazululo zokuqhekeka komhlaba kwezingxenye zepulasitiki

1. Ingcindezi eyinsalela iphezulu kakhulu

Mayelana nokusebenza kwenqubo, kuyindlela elula yokunciphisa ukucindezeleka okusele ngokunciphisa ukucindezela komjovo, ngoba ukucindezela komjovo kuhambisana nokucindezeleka okusalayo.Ngokuphathelene nokuklama kwesikhunta nokukhiqiza, isango eliqondile elinokulahlekelwa okuncane kwengcindezi kanye nokucindezela komjovo ophezulu kungasetshenziswa.Isango eliya phambili lingashintshwa libe amasango enaliti amaningi noma amasango aseceleni, futhi ububanzi besango bungancishiswa.Lapho uklama isango elihlangothini, isango le-convex lingasetshenziswa elingasusa ingxenye ephukile ngemva kokubunjwa.

2. Ukuhlushwa kokucindezeleka okusele okubangelwa amandla angaphandle

Ngaphambi kokudiliza izingxenye zepulasitiki, uma indawo ye-cross-sectional ye-demoulding ejection mechanism incane kakhulu noma inani lezinduku ze-ejector alanele, isikhundla sezinduku ze-ejector asinangqondo noma ukufakwa kuthambekele, ibhalansi impofu, i-demoulding. ukuthambeka kwesikhunta akwanele, futhi ukumelana ne-ejection kukhulu kakhulu, ukugxila kokucindezeleka kuzobangelwa amandla angaphandle, okuholela ekuqhekekeni nokuqhekeka ebusweni bezingxenye zepulasitiki.Uma kwenzeka kuba namaphutha anjalo, idivayisi yokukhipha izobhekwa ngokucophelela futhi ilungiswe.

3. Imifantu ebangelwa ukufakwa kwensimbi

I-thermal expansion coefficient ye-thermoplastic inkulu ngokuphindwe ka-9-11 kunensimbi kanye nezikhathi ezi-6 ezinkulu kune-aluminium.Ngakho-ke, ukufakwa kwensimbi engxenyeni yepulasitiki kuzovimbela ukuncipha okuphelele kwengxenye yepulasitiki, futhi ukucindezeleka okubangelwa ukucindezeleka kukhulu.Inani elikhulu lokucindezeleka okusalayo lizoqoqa eduze kokufaka futhi libangele imifantu ebusweni bengxenye yepulasitiki.Ngale ndlela, ukufakwa kwensimbi kufanele kufakwe ngaphambili, ikakhulukazi lapho ukuqhekeka ebusweni bezingxenye zepulasitiki kwenzeka ekuqaleni komshini, iningi labo libangelwa ukushisa okuphansi kokufakwayo.

4. Ukukhetha okungalungile noma izinto zokusetshenziswa ezingahlanzekile

Izinto zokusetshenziswa ezihlukene zinokuzwela okuhlukile ekucindezelekeni kwensalela.Ngokuvamile, i-non-crystalline resin ithambekele kakhulu ekucindezelekeni okuyinsalela kanye nokuqhekeka kune-crystalline resin;I-resin enokuqukethwe okuphezulu okugaywe kabusha inokungcola okwengeziwe, okuqukethwe okuguquguqukayo okuphezulu, amandla aphansi wento, futhi ijwayele ukuqhekeka.

5. Ukwakheka okungekuhle kwezingxenye zepulasitiki

Amakhona acijile namanotshi esakhiweni sengxenye yepulasitiki cishe azokhiqiza ukugxilisa ingqondo kokucindezeleka, okuholela ekuqhekekeni nokuqhekeka ebusweni bengxenye yepulasitiki.Ngakho-ke, amakhona angaphandle nangaphakathi esakhiwo sengxenye yepulasitiki kufanele enziwe ama-arcs ane-radius enkulu ngangokunokwenzeka.

6. Imifantu esikhunjeni

Enqubweni yokubunjwa komjovo, ngenxa yomphumela ophindaphindiwe wokucindezelwa komjovo esikhunjeni, imifantu yokukhathala izokwenzeka emaphethelweni ngama-engeli abukhali emgodini, ikakhulukazi eduze nezimbobo zokupholisa.Uma kwenzeka ukuqhekeka okunjalo, bheka ngokushesha ukuthi ingaphezulu le-cavity elihambisana nokuqhekeka kunoqhekeko olufanayo.Uma ukuqhekeka kubangelwa ukucabangela, isikhunta sizolungiswa ngomshini.

Imikhiqizo yepulasitiki evamile ekuphileni, njengeabapheki berayisi, imishini yamasemishi,iziqukathi zokudla, amabhokisi epulasitiki okudla kwasemini, amathini okugcina,ukufakwa kwamapayipi epulasitiki, njll., ingagwema ngempumelelo imifantu engaphezulu.
