Iimbangela zeDelamination
I-Delamination ingenzeka ngenxa yoku:
- Ukuxubana kweMathiriyeli okungonelanga: Ukudibanisa kakubi kwezinto ngexesha lokubumba kunokubangela i-delamination.
- Ukungcoliseka kwezinto: Izinto ezingcolisayo ezifakwe ngexesha lokuphatha izinto okanye ukulungiswa kunokubangela ukuba iileya zihlukane.
- Ubushushu bokuNyibilika obunganelanga: Imimiselo yobushushu obungachanekanga bunokuba negalelo kwi-delamination.
Ukubhabha: Ingxaki yesantya
I-Jetting yinto apho isantya esiphezulu sezinto zeplastiki ezinyibilikisiweyo zichaphazela i-mold surface, ukudala imigca ebonakalayo okanye imigca kwindawo egqityiweyo. Ihlala ihambelana nokusetyenziswa kwezinto eziphezulu ze-viscosity.
Iimbangela zeJetting
I-Jetting inokuqalwa:
- Isantya esiphezulu sokutofa: Izantya zesitofu ezigqithisileyo zingakhokelela kwijetting, njengoko izinto eziphathekayo zichaphazela umphezulu wokungunda kunokuhamba kakuhle kwimingxuma.
- Uyilo lweSango: Uyilo lwesango olungafanelekanga lunokwandisa imiba ye-jetting.
Imigca Ehambayo: Indlela yokuNchasa okuncinci
Imigca ehambayo, eyaziwa ngokuba “imigca weld” okanye “imigca ezinithiweyo,” zidla ngokubonakala njengemigca engacacanga okanye iinduli kumphezulu wenxalenye. Zenzeka xa ukuhamba kwezinto zeplastiki ezityhidiweyo zidibana nokuchasana kwaye ziphinde zidibanise, zishiya i-seam ebonakalayo.
Iimbangela zeMizila eHambayo
Imigca ehambayo inokuvela:
- Ukupholisa izinto eziphathekayo: Ukwahluka kwimilinganiselo yokupholisa kunokubangela ukuba izinto ziqiniswe ngamaxesha ahlukeneyo, okukhokelela kwimigca yokuhamba.
- Inxalenye yeJiyometri entsonkothileyo: Amalungu anejometri ezintsonkothileyo okanye amasebe amaninzi achaphazeleka lula kwimigca yokuhamba.
Ubuchule bokuNciphisa isiphene
Ukunciphisa ezi ziphene kufuna indibaniselwano yoyilo, usetyenziso lwenkqubo, kunye nokukhethwa kwezinto:
- Ukuyilwa ngokutsha kweSango: Uyilo olululo lwesango kunye nokubekwa kunokunciphisa umngcipheko wamanqaku okutsha, i-delamination, kunye nejetting.
- Isantya sokutofa esilungiselelweyo: Lawula isantya sokutofa ukunqanda ukufudumeza kunye nejetting ngelixa uqinisekisa ukuhamba kwezinto ezifanelekileyo.
- Ukukhethwa kwezinto: Khetha imathiriyeli engafane yenzeke kakhulu ekutshisweni kwamanqaku kunye ne-delamination.
- Izixhobo kunye noyilo lokungunda: Sebenzisa utshintsho lwezixhobo kunye nokuphuculwa koyilo lokungunda ukunciphisa ukubakho kwemigca yokuhamba.
Inkungu: Inkungu yokungafezeki
Inkungu, edla ngokubizwa ngokuba “zinc” okanye “inkungu,” ibonakala ngathi kukho amafu okanye umphezulu omfiliba kwindawo ebunjiweyo. Esi siphene sinokuchaphazela kakhulu i-aesthetics yemveliso kunye nokucaca.
Oonobangela beNkungu
Inkungu ingenzeka ngenxa yoku:
- Ukungcoliseka kwezinto: Ungcoliseko olungeniswa ngexesha lokuphatha izinto okanye ukusetyenzwa lungakhokelela kwinkungu.
- Ukutshisa ngokugqithisileyo: Ukushisa okugqithisileyo ngexesha lenkqubo yokubumba kunokubangela ukuba izinto zihlaziywe, kubangele inkungu.
Amanqaku eSinki: Umngeni wokuNgenisa
Amanqaku e-sink kukudandatheka okanye ukungena kumphezulu wenxalenye ebunjiweyo. Zenzeka xa umphezulu wecandelo elijiyileyo lenxalenye liphola kwaye liqina kancinci kuneendawo zangaphakathi.
Iimbangela zamanqaku eSinki
Amanqaku e-sink anokubangelwa:
- Ukupholisa okungonelanga: Ukupholisa okungalinganiyo, ngakumbi kwiindawo ezityebileyo zenxalenye, kunokukhokelela kumanqaku okutshona.
- Ukuncipha kwezinto: Amazinga ahlukeneyo okucutheka ngaphakathi kwendawo angabangela amanqaku e-sink.
Weld Lines: Apho Materials Dibana
imigca weld, eyaziwa ngokuba “imigca ezinithiweyo,” Kwenzeka xa iiplastiki ezimbini okanye ngaphezulu ezinyibilikisiweyo zidibana kwaye ziphinda zihlangane ngexesha lenkqubo yokutofa. Le migca idla ngokubonakala kumphezulu wenxalenye egqityiweyo kwaye inokuchaphazela ingqibelelo yayo yesakhiwo.
Iimbangela zeWeld Lines
Imigca ye-weld inokwakheka ngenxa:
- Imiqobo yokuHamba kwezinto: Imiqobo okanye ijometri ngaphakathi kwesikhunta sinokubangela ukuba ukuhamba kwezinto kuhlukane kwaye kuhlangane kwakhona.
- Ukupholisa izinto eziphathekayo: Ukwahluka kwimilinganiselo yokupholisa kunokukhokelela ekubunjweni kwemigca ye-weld.
Imijelo: Amanqaku angabonakaliyo
Imijelo, njengoko igama labo libonisa, imigca ebonakalayo okanye imigca ebusweni benxalenye ebunjiweyo. Zinokubangelwa zizinto ezahlukeneyo kwaye zihlala zinzima ukuxilonga nokusombulula.
Izinto ezibangela imivimbo
Uluhlu lunokuvela:
- Ukungcoliseka kwezinto: Ukungcola okanye ukungcola kwizinto eziphathekayo kunokubangela imivimbo.
- Ukuxuba okungonelanga: Ukuxubana kakubi kwezinto eziphathekayo kunokukhokelela ekubunjweni kwe-streak.
Ubuchule bokuSombulula isiphene
Ukusombulula le mingeni kufuna indibaniselwano yoyilo, ukwenziwa kwenkqubo, kunye nolawulo lwemathiriyeli:
- Ubunyulu bezinto eziphathekayo: Qinisekisa ukuba izinto ezisetyenzisiweyo azinangcoliseko kunye nokungcola.
- UPhulo lokuPholisa: Lungiselela izicwangciso zokupholisa ukunciphisa umngcipheko weempawu zokucwila kunye nenkungu.
- Uphononongo loYilo lokungunda: Ngokuqhubekayo uphonononga uyilo lokubumba ukuchonga imithombo enokubakho yemigca ye-weld kunye nemivimbo.
- Ukukhethwa kwezinto: Khetha ngokucokisekileyo izixhobo ezinokuthi zifane ne-streak formation kunye nezinye iziphene.
