Umgca we-Weld yinto ebalulekileyo echaphazela umgangatho weengxenye zeplastiki.Umzekelo, kushishino lweemoto, Umzekelo, kushishino lweemoto,iibhampa zemoto, Qeda ukufakelanjl.Ke ngoko, kubaluleke kakhulu ukufundisa inkqubo yokwakheka kunye neempembelelo zemiba ye-weld kwaye ufumane iindlela zokuphelisa imigca ye-weld.
Kukho iintlobo ezimbini ezisisiseko zemigca ye-weld kwiindawo ezibunjiweyo zenaliti: enye ngumgca we-weld obandayo;Enye i-hot-melt weld mark.
Izinto ezichaphazelayo zomgca we-weld kunye nemilinganiselo yokuphucula kunye nokuphelisa
1. Impembelelo yenkqubo yokubumba i-injection parameters kumgca we-weld
a.Isiphumo sobushushu
Ukonyusa iqondo lobushushu kunokukhawulezisa inkqubo yokuphumla kwepolymer kwaye kunciphise ixesha lokuphonswa kwetsheyini yemolekyuli, nto leyo inceda ngakumbi ukudityaniswa okugcweleyo, ukusasazwa kunye nokuphonswa kweemolekyuli ngaphambili kwisiphelo sezinto, ukuze kuphuculwe amandla indawo ye weld line.Iqondo lobushushu lokunyibilika linempembelelo enkulu kumandla we weld lineABS iinxalenye zeplastiki.
b.Impembelelo yoxinzelelo lwenaliti kunye nokubamba uxinzelelo
Uxinzelelo lwe-injection luyinto ebalulekileyo ekuzaliseni iplastiki yokunyibilika kunye nokubumba.Indima yayo kukoyisa ukuxhathisa kweplastiki enyibilikayo equkuqela emgqonyeni, emlonyeni, kwisixokelelwano sesango kunye nomgodi, ukunika isantya esaneleyo sokuzalisa ukunyibilika kweplastiki, kunye nokudibanisa ukunyibilika ukuqinisekisa umgangatho weemveliso ezibunjiweyo zenaliti.
c.Isiphumo sesantya sokutofa kunye nexesha lokutofa
Ukonyusa isantya senaliti kunye nokunciphisa ixesha lokutofa kuya kunciphisa ixesha lokuhamba phambi kokuba umphambili wokunyibilika udibane, ukunciphisa ilahleko yobushushu, ukomeleza isizukulwana sobushushu be-shear, ukunciphisa i-viscosity yokunyibilika kunye nokwandisa ulwelo, ukuze kuphuculwe amandla omgca we-weld. .
2. Impembelelo yoyilo lwe-die kumgca we-weld
a.Uyilo lwenkqubo yokungena
Okukhona inani lamasango, kokukhona amanqaku e-weld aya kuveliswa.Ukuba inyibilika phambi kokuhamba kwezinto ezivela kwisango ngalinye ayinakuxutywa kakuhle, amanqaku e-weld aya kuba nzima kwaye umgangatho wezinto zeplastiki ziya kuchaphazeleka kakhulu.
b.Uyilo lwenkqubo yokukhupha kunye nokutshaja okubandayo kakuhle
Irhasi eshiyekileyo eyenziwe ngenxa yokukhupha kakubi ixinzelelwe kwi-mold cavity ngexesha lenkqubo yokutofa, engayi kutshisa kuphela iimveliso, kodwa ikhokelela ekubonakaleni kwamanqaku okudibanisa.
c.Uyilo lwenkqubo yokulawula ubushushu
Iqondo eliphantsi lobushushu lokungunda, kokukhona lingathandekiyo kwi-fusion epheleleyo yokunyibilika.
d.Uyilo loburhabaxa bomphezulu wecango kunye nombindi
Uburhabaxa bomphezulu bomphezulu kunye nombindi kuya kuchaphazela isantya sokuzaliswa kwesantya sokunyibilika kweplastiki.
e.Ukuphuculwa kolwakhiwo lokufa kweminye imiba
Imodeli eluncedo inxulumene nolwakhiwo lokungunda olunokuphelisa uphawu lokudityaniswa kwenkangeleko yemveliso exonxiweyo yesitofu esinezibilini.Indlela ethile kukuba xa imveliso ifakwe nje kwaye izaliswe kwi-mold cavity, izinto ezithambileyo zinyibilika kwi-mold cavity iyasikwa ngokusebenzisa i-core insert ukufumana umngxuma wemveliso.
3. Impembelelo ye-valve yenaliti yesango le-teknoloji elandelelanayo kumgca we-weld
Kwinkqubo yokuvelisa ubuninzi beemveliso, phantse zonke iindawo ezinkulu zokubumba iinaliti zamkela inkqubo yembaleki eshushu.Ngolu hlobo lweengxenye zeplastiki, ukutya kweglue kwisango lesango kunokuqinisekisa ukuzaliswa okupheleleyo komgodi kunye nokuphucula ukusebenza kakuhle kokuzaliswa, kodwa ngokuqinisekileyo kuya kuvelisa ukuhamba kwezinto zesebe, okukhokelela ekuveleni kwemigca ye-weld.Ngokuvula inaliti yevalve yesango ngokulandelelanayo, ukuhamba kwe-nyibilika kunokudityaniswa kuzo zombini iziphelo zomgobo ngokulandelelana, ukusombulula ingxaki yophawu lwe-weld.
4. Ezinye iindlela zokuphucula amandla omgca we-weld
a.Ukutyhala kabini indlela yokuzalisa ukungunda
b.I-Vibration incedise ukubumba inaliti
