Weld line chinhu chakakosha chinokanganisa kunaka kwezvikamu zvepurasitiki.Semuenzaniso, muindasitiri yemotokari, Semuyenzaniso, muindasitiri yemotokari,mabhampa emotokari, End Fitting, nezvimwewo, zvikamu zvepurasitiki zvisina kukodzera zvinotungamira zvakananga mukudzikira kwemhando yemotokari uye kunyange kuisa pangozi hupenyu hwevanhu.Nokudaro, zvakakosha zvikuru kudzidza maitiro ekugadzira uye kupesvedzera zvinhu zve weld mitsara uye kutsvaga nzira dzekubvisa mitsetse ye weld.
Kune mhando mbiri dzinokosha dzemitsetse ye weld muzvikamu zvakaumbwa zvejekiseni: imwe inotonhora weld line;Imwe yacho ndeye hot-melt weld mark.
Kupesvedzera zvinhu zve weld line uye zviyero zvekuvandudza nekubvisa
1. Kufurira kwejekiseni molding process parameters pane weld line
a.Mhedzisiro yekushisa
Kuwedzera tembiricha kunogona kumhanyisa maitiro ekuzorora epolymer uye kuderedza nguva yekusungirirwa kwema molecular chain, iyo inonyanya kubatsira kune yakazara fusion, kupararira uye kupinzwa kwemamorekuru kumberi kwechinyorwa, kuitira kuvandudza simba re the weld line area.The melt tembiricha ine simba guru pane weld line simba reABS plastiki zvikamu.
b.Mhedzisiro yejekiseni pressure uye kubata pressure
Jekiseni pressure chinhu chakakosha mupurasitiki kunyungudika kuzadza uye kuumba.Basa rayo nderekukunda kupokana kwepurasitiki inonyunguduka ichiyerera mumbiru, nozzle, gating system uye mhango, kupa kukurumidza kuzadza kumapurasitiki kunyunguduka, uye kubatanidza iyo kunyungudika kuve nechokwadi chemhando yezvigadzirwa zvakaumbwa jekiseni.
c.Mhedzisiro yekumhanyisa jekiseni uye nguva yejekiseni
Kuwedzera kumhanya kwejekiseni uye kupfupisa nguva yejekiseni kunoderedza kuyerera nguva isati yanyunguduka isati yasangana, kuderedza kurasikirwa kwekupisa, kusimbisa chizvarwa chekupisa cheshear, kuderedza kunyunguduka viscosity uye kuwedzera fluidity, kuitira kuti uvandudze simba reiyo weld mutsara. .
2. Pesvedzero yekugadzira kufa pane weld line
a.Dhizaini ye gating system
Kuwanda kwenhamba yemagedhi, iyo yakawanda weld mamakisi ichagadzirwa.Kana iyo yakanyunguduka pamberi pekuyerera kwezvinhu kubva kugedhi rega rega haigone kusanganiswa zvakanaka, iwo weld mamaki anozowedzerwa uye kunaka kwezvikamu zvepurasitiki kuchakanganiswa zvakanyanya.
b.Dhizaini ye exhaust system uye inotonhora yekuchaja zvakanaka
Iyo yakasara gasi inogadzirwa nekuda kwekutadza kupera inomanikidzwa mugomba remuvhu panguva yejekiseni, iyo isingazopise zvigadzirwa chete, asi zvakare inotungamira mukuonekwa kweiyo fusion mamaki.
c.Dhizaini yekudzora tembiricha system
Iyo yakaderera tembiricha ye mold, zvakanyanya kusafarira kune yakazara fusion yekunyungudika.
d.Dhizaini yekushata kwepamusoro kwegomba uye core
Iko kushata kwepamusoro kwegomba uye musimboti kuchakanganisawo kuzadza kuyerera velocity yepurasitiki yakanyungudika.
e.Kuvandudzwa kwechimiro chekufa mune zvimwe zvinhu
Iyo yekushandisa modhi ine chekuita nechimiro che mold chinogona kubvisa chitarisiko chekusanganisa chiratidzo che porous jekiseni rakaumbwa chigadzirwa.Iyo chaiyo nzira ndeyokuti kana chigadzirwa chichangobva kubaiwa uye kuzadzwa mugomba remuvhu, iyo yakapfava inonyungudika mugomba rekuumbwa inochekwa nekushandisa core insert kuwana gomba rechigadzirwa.
3. Kufurira kweinotevedzana valve tsono gedhi tekinoroji pane weld line
Mune yakanyanya otomatiki misa yekugadzira maitiro ezvigadzirwa, anenge ese makuru majekiseni ekuumba zvikamu anotora inopisa mumhanyi system.Kune iyi mhando yezvikamu zvepurasitiki, akawanda gedhi glue kudyisa kunogona kuve nechokwadi kuzadzwa kwakazara kwegomba uye kunatsiridza kuzadza mashandiro, asi inozoburitsa kuyerera kwebazi, zvichikonzera kubuda kwemitsara ye weld.Nekuvhura tsono yegedhi revharuvhu mukutevedzana, kunyungudika kuyerera kunogona kusanganiswa kune ese maperero egomba pamwe chete, kuitira kugadzirisa dambudziko reweld mark.
4. Dzimwe nzira dzekuvandudza simba re weld line
a.Kaviri push mold yekuzadza nzira
b.Vibration inobatsira jekiseni kuumba
