Kuhlengahlengiso lwethu lomatshini, sihlala sisebenzisa inaliti enamanqanaba amaninzi.Inqanaba lokuqala lesango lokulawula inaliti, inqanaba lesibini lokulawula isitofu somzimba ophambili, kunye nenqanaba lesithathu lenaliti lizalise i-95% yemveliso, kwaye emva koko iqalise ukugcina uxinzelelo lokuvelisa imveliso epheleleyo.Phakathi kwabo, isantya se-injection silawula isantya sokuzaliswa kokunyibilika, uxinzelelo lwe-injection sisiqinisekiso somlinganiselo wokuzalisa, indawo yokujova ilawula indawo yokuncibilika, kunye noxinzelelo lokugcina uxinzelelo lusetyenziselwa ukulungisa ubunzima bemveliso, ubungakanani, ukuguqulwa, kunye ukushwabana.
>> Ukuzimisela kokuqala koxinzelelo lwenaliti ngexesha lokuqalisa kwemveliso kunye nokugunyaziswa:
Ukuqala kwethu umatshini wohlengahlengiso lweparamitha, uxinzelelo lwenaliti luya kuba phezulu kunexabiso elibekiweyo.
Ngenxa yokuba uxinzelelo lwenaliti luphantsi kakhulu, iisitofu sokungunda(ubushushu) bubanda kakhulu, kwaye ibala le-oyile kumphezulu womgodi wokungunda ngokuqinisekileyo liya kubangela ukuxhathisa okukhulu.Kunzima ukujova i-melt kwi-mold cavity, kwaye ayinakwenziwa ngenxa yoxinzelelo olunganeleyo (ukunamathela kwi-mold yangaphambili, ukuvala isango);Xa uxinzelelo lwe-injection luphezulu kakhulu, imveliso iya kuba noxinzelelo olukhulu lwangaphakathi, olulula ukubangela i-burrs kunye nokunciphisa ubomi benkonzo yokubumba.Isenokukhokelela kwindawo yokuplaga yemveliso, ubunzima bokudiliza, imikrwelo kumphezulu wemveliso, kwaye nokungunda kuya kwandiswa kwiimeko ezimandundu.Ke ngoko, uxinzelelo lwenaliti kufuneka lubekwe ngokwala manqaku alandelayo ngexesha lokuqalisa kunye nokugunyaziswa.
1. Ubume bemveliso kunye nokuma.
2. Ubungakanani bemveliso (ubude bokunyibilika kokunyibilika).
3. Ubukhulu bemveliso.
4. Izinto ezisetyenziswayo.
5. Uhlobo lwesango lokungunda.
6. Ubushushu be-Screw somatshini wokubumba inaliti.
7. Iqondo lobushushu lokungunda (kubandakanywa nobushushu bokufudumala kwesikhunta).
>> Iziphene eziqhelekileyo ezibangelwa uxinzelelo lwenaliti kwimveliso
Uxinzelelo lwenaliti lusetyenziselwa ukugcwalisa kunye nokutya kwe-melted kwi-mold cavity.
Ekufakeni isitofu sokubumba, uxinzelelo lwenaliti lukhona ukuze loyise ukumelana nokuzaliswa.Xa inyibilika itofwe, kufuneka yoyise ukuxhathisa kwisango lesango lembaleki yombhobho ukukhupha imveliso.Xa uxinzelelo lwenaliti ludlula ukuchasana nokuhamba, ukunyibilika kuya kuhamba.Ayichanekanga njengesantya sokutofa kunye nendawo yokutofa.Ngokuqhelekileyo, silungisa imveliso ngesantya njengesalathiso.Ukunyuka koxinzelelo lwenaliti kunokugcina ubushushu obuphezulu bokunyibilika kunye nokunciphisa ilahleko yokumelana nomjelo, Inxalenye yangaphakathi yemveliso iqinile kwaye inzima.
>> Zinzisa iiparamitha zenkqubo emva kokugunyaziswa kwemveliso
Izinto ezichaphazela ngokuthe ngqo ukunyanzeliswa kwenaliti: ukuhamba kwe-stroke yesisombululo, i-viscosity yezinto eziphathekayo kunye nobushushu bokubumba.
Kwimeko efanelekileyo, yeyona nto yenzululwazi ukuba uxinzelelo lwenaliti lulingana noxinzelelo lwe-mold cavity, kodwa uxinzelelo lwangempela lwe-mold cavity ayikwazi ukubalwa.Okukhona kunzima ukuzaliswa komngundo, kokukhona uxinzelelo lwenaliti lulukhulu, kwaye okukhona ubude bokunyibilika buhamba.Uxinzelelo lwenaliti luyancipha ngokunyuka kokumelana nokuzaliswa.Ke ngoko, inaliti yamanqanaba amaninzi yaziswa.Uxinzelelo lwenaliti ye-melt yangaphambili iphantsi, uxinzelelo lwenaliti yokunyibilika okuphakathi luphezulu, kwaye uxinzelelo lwenaliti yecandelo lokugqibela liphantsi.Isikhundla esikhawulezayo sikhawuleza kwaye indawo epholileyo iyacotha, kwaye iiparamitha zenkqubo kufuneka ziphuculwe emva kokuveliswa okuzinzileyo.
>> Izilumkiso zokhetho loxinzelelo lwenaliti:
1. Ngexesha lokulungiswa kweparameter, xa ukushisa kwesikhunta okanye ukugcinwa kweqondo lokushisa kuncipha, kuyimfuneko ukubeka uxinzelelo olukhulu lwenaliti.
2. Kwimathiriyeli ene-fluidity elungileyo, uxinzelelo lwenaliti esezantsi kufuneka lusetyenziswe;Kwizinto zeglasi kunye ne-viscosity ephezulu, kungcono ukusebenzisa uxinzelelo olukhulu lwenaliti.
3. Imveliso encinci, ixesha elide le nkqubo, kwaye inzima ngakumbi imilo, ubukhulu bexinzelelo lwenaliti esetyenziswayo, ehambelana nokuzaliswa kunye nokubumba.
4. Umlinganiselo we-scrap wemveliso uhambelana ngokuthe ngqo nokuba uxinzelelo lwe-injection lubekwe ngokufanelekileyo.Isiseko sozinzo kukuba izixhobo zokubumba zichanekile kwaye azikho iziphene ezifihliweyo.
