Iiparamitha eziphambili zenkqubo yeendawo ezibunjiweyo zenaliti zinokuhlelwa zibe zizinto ezi-4 ezibandakanya:Ubushushu be-cylinder, ubushushu obunyibilikayo, ubushushu bomngundo wokutofa, uxinzelelo lwenaliti.
1.Ubushushu beSilinda:Kuyaziwa ukuba impumelelo yamalungu abunjiweyo enaliti yeplastiki ixhomekeke kwizinto ezininzi, kubandakanywa ubushushu be-cylinder.Ubushushu be-cylinder kufuneka buphakame ngokwaneleyo ukuze kuqinisekiswe ukuba iplastiki inyibilikile xa ifika kwi-mold, kodwa ingabi phezulu kakhulu kangangokuba iplastiki iyancipha.Ukufikelela kwiqondo lokushisa elichanekileyo le-cylinder yibhalansi ethambileyo, kwaye enye edla ngokuba nzima ukuyigcina.Oku kubangelwa kukuba ubushushu bombhobho bunokutshintsha ngokukhawuleza kakhulu, kwaye bunokuchatshazelwa zizinto ezininzi, eziquka uhlobo lweplastiki esetyenziswayo, ubungakanani bokungunda, isantya sokutofa, kunye nobushushu obukummandla.Ukuze kuqinisekiswe ukuba ukushisa kwe-cylinder kugcinwa kwinqanaba elichanekileyo, kubalulekile ukusebenzisa isilawuli sokushisa.Oku kuya kunceda ukulawula ukushisa kwe-cylinder, kwaye kuthintele ukuguquguquka.Kukho inani leentlobo ezahlukeneyo zokulawula ukushisa ezikhoyo, kwaye kubalulekile ukukhetha enye efanelekileyo kwisicelo esithile.
2.Mubushushu obuphezulu:Ubushushu obunyibilikayo sesinye sezona parameters zibalulekileyo ekubumbeni inaliti, kwaye luphawu olulungileyo lwendlela iplastiki ezakuhamba ngayo ngexesha lenkqubo yokutofa.Ubushushu obunyibilikayo bunefuthe elithe ngqo kumandla kunye nokuzinza kwe-dimensional yecandelo elibunjiweyo.Kukho izinto ezimbalwa ezichaphazela ubushushu obunyibilikayo beplastiki, kubandakanywa ukwakheka kweekhemikhali zentlaka, uhlobo lweplastiki, kunye neemeko zokusetyenzwa.Ngokubanzi, ubushushu obuphezulu bokunyibilika bubangela ukuhamba kakuhle kunye nobushushu obuphantsi bokunyibilika bubangela uzinzo olungcono lwe-dimensional.Isantya sokutofa sisantya apho iplastiki enyibilikisiweyo itofelwa kukungunda kunye nobushushu bomgqomo bubushushu beplastiki njengoko itofwa. Ngokubanzi, isantya esiphezulu sokutofa kunye namaqondo obushushu emigqomo kukhokelela kubushushu obuphezulu bokunyibilika.Nangona kunjalo, ukuba isantya senaliti siphezulu kakhulu okanye ubushushu bomgqomo buphantsi kakhulu, iplastiki inokuthoba kwaye indawo ebunjiweyo inokuba kumgangatho ophantsi.
3.isitofu ngundo lobushushu:
Izixhobo ezahlukeneyo zifuna ubushushu obuhlukeneyo bokubumba inaliti ukuze inyibilike ngokufanelekileyo kunye nokungunda.Iqondo lobushushu elithile oya kulidinga liya kuxhomekeka kubungakanani kunye nobukhulu bemathiriyeli yakho.Ukuseta ubushushu bakho bokubumba inaliti, kuya kufuneka uqale uqonde ukuba loluphi ubushushu obusebenza ngcono kwizinto zakho ezithile,njenge-PC ngokubanzi ifuna ngaphezu kwe-60 degrees, kunye ne-PPS ukuze kuphunyezwe inkangeleko engcono kunye nokuphucula ukuhamba, iqondo lokushisa lokungunda ngamanye amaxesha lifuna ngaphezu kwe-160 degrees Emva kokuba uyazi oku, ungasebenzisa i-thermometer ukulinganisa nokuseta ubushushu bakho. umatshini wokubumba.
4.uxinzelelo lwesitofu:Olu luxinzelelo apho iplastiki etyhidiweyo itofwa kwi-mold.Iphezulu kakhulu kwaye iplastiki iya kuhamba ngokukhawuleza, okukhokelela kwinxalenye eneendonga ezincinci kunye nokuchaneka okungahambi kakuhle.Iphantsi kakhulu kwaye iplastiki iya kuhamba ngokucothayo kakhulu, okukhokelela kwinxalenye eneendonga ezishinyeneyo kunye nomgangatho ongemhle wokuhombisa.Ukuchasana okufunekayo kwi-melt ukunqoba ukuqhubela phambili kuchaphazela ngokuthe ngqo ubungakanani, ubunzima kunye nokuguqulwa kwemveliso, njl.Iimveliso zeplastiki ezahlukeneyo zifuna uxinzelelo lwenaliti olwahlukileyo.Kwizinto ezifana ne-PA, i-PP, njl., ukunyusa uxinzelelo kuya kubangela ukuphuculwa okubonakalayo kwi-fluidity.Ubungakanani boxinzelelo lwenaliti bumisela ukuxinana kwemveliso, oko kukuthi inkangeleko ekhazimlayo.Ayinalo ixabiso eliqingqiweyo, kwaye kunzima ngakumbi ukubumba kuzaliswe, uxinzelelo lwecandelo elijojowe liyanda.
Xa uyilo lwakho lufika kwiindawo zokubumba iinaliti.Ngaba wakha wadibana nobu bunzima obukucaphukisayo?Indlela yokwenza ngokugqibeleleyo ubukhulu becala ngaphezu kwe-4CM okanye ubude obungaphezulu kwe-1.5M?Indlela yokwenza imveliso egobileyo ngaphandle kokuguqulwa?Okanye indlela yokuphatha ii-undercuts ezinzima ... njl.
Ukuba usokola nemingeni, Ukuba ujonge iqela elizinzileyo nelichubekileyo ukuze likuncede ulungise iingxaki?
I-Ruicheng- isisombululi sakho sengxaki esigqwesileyo kunye nesixhobo sakho esiyimfihlo, ngubani onamava angaphezulu kweminyaka engama-20 yokutofa amalungu eplastiki aya kukunceda wophule obu bunzima / imiqobo yobuchwephesha kwaye ujike izinto ezichaziweyo "ezingenakwenzeka" zibe yinyani?
