I-Dongguan Enuo mold Co., Ltd iyinxalenye yeQela le-Hong Kong BHD, uyilo lokubumba iplastiki kunye nokuvelisa lishishini labo elingundoqo. Ngaphaya koko, iinxalenye zentsimbi ze-CNC machining, iimveliso zeprototype ze-R&D, indawo yokuhlola/Isilinganisi se-R&D, ukubunjwa kweemveliso zeplastiki, ukutshiza kunye nokuhlanganisa nazo ziyabandakanyeka.

Yiyiphi imiba ekufuneka ihlawulwe ingqalelo ekuveliseni iimbumba zeplastiki?

Ngethuba lemveliso, xa i-plastiki inyibilika ifakwe kwi-mold cavity phantsi kobushushu obuphezulu kunye noxinzelelo oluphezulu kwaye ibunjwe phantsi koxinzelelo, xa iqondo lokushisa lihla, ukunyibilika kupholisa kwaye kuqiniswe kwinxalenye yeplastiki. Ubungakanani becala leplastiki lincinci kunolo lomgodi wokungunda, obizwa ngokuba mfutshane. Ezona zizathu zokwenza mfutshane zezi zilandelayo. Xa usenza iplastiki, imilinganiselo ye-cross-sectional yamasango okubumba ahlukeneyo ahlukeneyo. Isango elikhulu linceda ukunyusa uxinzelelo lombhobho, ukwandisa ixesha lokuvala isango, kunye nokuququzelela ukunyibilika okungaphezulu kwi-cavity, ngoko ke ubuninzi benxalenye yeplastiki bukhulu kakhulu, ngaloo ndlela kunciphisa izinga lokunciphisa, kungenjalo kuya kwandisa ukucutha. izinga.

Utshintsho kwisakhiwo sekhemikhali yesikhunta seplastiki ngexesha lenkqubo yokuvelisa. Ezinye iiplastiki zitshintsha ukwakheka kweekhemikhali ngexesha lokubumba. Ngokomzekelo, kwiiplastiki ze-thermosetting, i-molecule ye-resin iyatshintsha ukusuka kwisakhiwo somgca ukuya kwisakhiwo esifana nomzimba. Ubunzima be-volumetric yesakhiwo esifana nomzimba sikhulu kunokwakheka komgca, ngoko umthamo wayo uphela ufinyeziwe, okubangela ukuba kuncitshiswe. Iinxalenye zeplastiki ezinodonga olubhityileyo ezinobunzima obufanayo bodonga zipholiswa ngokukhawuleza kumgodi wokungunda, kwaye isantya sokunciphisa sithande ukuba sincinci emva kokudilizwa. Ixesha elide leplastiki eshinyeneyo enobunzima obufanayo bodonga ukuze iphole emngxunyeni, kokukhona ukufinyezwa okukhulu emva kokudilizwa. Ukuba ubukhulu benxalenye yeplastiki buhluke, kuya kubakho iqondo elithile lokunciphisa emva kokudiliza. Kwimeko yotshintsho olunjalo ngokukhawuleza kwindonga yodonga, izinga lokunciphisa liya kutshintsha ngokukhawuleza, okubangela uxinzelelo olukhulu lwangaphakathi.

Uxinzelelo olushiyekileyo lutshintsha. Xa iinxalenye zeplastiki zibunjwa, ngenxa yempembelelo yoxinzelelo lokubumba kunye ne-shear force, i-anisotropy, ukuxuba ukungalingani kwezongezo kunye nobushushu bokubumba, kukho uxinzelelo olushiyekileyo kwiindawo zeplastiki ezibunjiweyo, kwaye uxinzelelo olushiyekileyo luya kuba luncinci kwaye lusasazeke kwakhona, okukhokelela kwiindawo zeplastiki Ukunciphisa kwakhona kubizwa ngokuba yi-post-shortening.
