Ubushushu bomngundo weplastiki bunempembelelo enkulu kumgangatho wokubumba wemveliso. Yenye yeemeko ezintathu eziphambili zenkqubo yokubumba inaliti. Ukubunjwa kwe-injection ngokuchanekileyo, akukho kuphela ingxaki yokushisa okuphezulu kunye nokuphantsi, kodwa kunye nengxaki yokuchaneka kokulawula ukushisa. Ngokucacileyo, ikukubumba ngokuchaneka kwesitofu. Kwinkqubo, ukuba ulawulo lokushisa aluchanekanga, ukunyibilika kweplastiki kunye nokusebenza kokubumba kunye nesantya sokunciphisa imveliso akuyi kuzinza, ngoko ke ukuchaneka kwemveliso egqityiweyo akunakuqinisekiswa. Ngokuqhelekileyo, indlela yokudibanisa inkqubo efana nebhokisi yokulawula ukushisa kunye nendandatho yokufudumeza isetyenziselwa ukulawula ukushisa kwephantom.
1. Kukho iindlela ezininzi zokufudumeza okanye ukupholisa umzimba wokubumba weplastiki ukulungelelanisa ubushushu. Umphunga, ukujikeleza kwe-oyile eshushu, ukujikeleza kwamanzi ashushu kunye nokumelana kungasetyenziselwa ukufudumeza umzimba wokungunda. Ukupholisa amanzi ajikelezayo okanye amanzi okupholisa angasetyenziselwa ukupholisa umzimba wokungunda. Umoya uyaqhutywa. Ukulungelelaniswa kweqondo lokushisa kwi-mold esetyenziswe kumatshini wokubumba inaliti, ukufudumeza ukuxhathisa kunye nokupholisa kwamanzi okujikeleza ukupholisa kusetyenziswe ngokubanzi. Xa isikhunta sitshisa ngokuchasa, inxalenye ethe tyaba ishushu ngocingo oluxhathisayo, inxalenye ye-cylindrical ifudumeza i-coil yokufudumala yombane, kwaye ingaphakathi lokubumba lifudumala ngentonga yokufudumala yombane. Umngundo kufuneka upholiswe ngokucwangcisa umbhobho wamanzi ojikelezayo wokupholisa. Ukumelana nokufudumeza kunye nokujikeleza kwamanzi okupholisa, ezi zimbini zisebenza ngokutshintshana ngokweemeko zobushushu bomzimba wokungunda, ukuze ubushushu bomngundo bulawuleke ngaphakathi koluhlu lobushushu olufunwa yinkqubo.
2. Amanyathelo okuthintela ubushushu bomngundo:
(1) Iqondo lobushushu lenxalenye nganye yokubumba yokubumba emva kokufudumeza kufuneka ifane ukuze kuqinisekiswe ukuba ukunyibilika kunomgangatho ongcono wokuzalisa, ukwenzela ukuba umgangatho wokubumba wemveliso etyhidiweyo yesitofu uqinisekisiwe, kunye nesantya sokupasa kwemveliso etyhidiweyo. iyaphuculwa.
(2) Inkqubo yokulungiswa kweqondo lokushisa lomzimba wokubumba kufuneka igqitywe yi-viscosity yokunyibilika. Ukuze i-viscosity ephezulu iyanyibilika ukuba ifakwe kwi-mold, ubushushu bomzimba wokungunda kufuneka buhlengahlengiswe kancinci; ngelixa i-viscosity esezantsi iyanyibilika ukuzalisa ukungunda, ubushushu bomzimba wokungunda bunokuthotywa ngokufanelekileyo. Xa ulungiselela ukuveliswa kwenaliti, ubushushu bomzimba wokungunda bungaphakathi koluhlu lweemfuno zenkqubo. Ukuze kuqinisekiswe ubushushu obufanayo bomzimba wokubumba, umzimba wokubumba obushushu obufunwa yinkqubo yokufudumala kufuneka ugcinwe kwiqondo lokushisa elihlala lihlala ixesha elithile.
3 ekubeni mde kakhulu. Ukupholisa ngelixa ujikelezayo kwandisa i-viscosity yokunyibilika, okunciphisa ukuhamba kwezinto, kuchaphazela umgangatho wenaliti enyibilikayo kunye nokuzaliswa kwesikhunta, kwaye kubangela ukuba ukunyibilika kuphole kwaye kuqiniswe kwangaphambili, okwenza umatshini wokubumba inaliti ungenakwenzeka.
(4) Ukuze kuncitshiswe iqondo lobushushu lokunyibilika ngenxa yomjelo omde wokunyibilika kunye nokwandisa ilahleko yamandla obushushu, umaleko okhusela ubushushu nowokunyakamisa kufuneka wongezwe phakathi kwenxalenye yobushushu obuphantsi bomgodi wokungunda kunye nenxalenye yobushushu obuphezulu. Umjelo wokuhamba onyibilikayo.
