Indima yepayipi lokungena

Izinhlobo eziningi zokuthatha amandla ezimoto bezilokhu zenziwe ngensimbi.Ngenxa yokuma okuyinkimbinkimbi kwe-manifold, ngaphambili yayiphonswe nge-aluminium alloy, kodwa udonga lwangaphakathi luqinile, ukumelana nomoya ngesikhathi sokusetshenziswa kukhulu, futhi umsindo mkhulu, okuholela ekushiseni okwanele kanye nokukhishwa kwe-exhaust ngokweqile.Kusukela ngeminyaka yawo-1980, iYurophu yaqala ukusebenzisa indlela yokukhiqiza ewumgogodla elahlekile (CoreMelt).

I-manifold eyenziwe ngale ndlela ayibizi nje kuphela, kodwa futhi inezinga elithile lokulahla, ngoba impahla ye-manifold yi-PA66 (noma i-PA6) ngemuva kokuqinisa i-fiber fiber., izinga lokushisa lokucubungula liyi-250 kuya ku-260 ° C, nakuba isikhathi sokuthintana nomgogodla ekubunjweni singamaminithi ambalwa kuphela, kodwa ingxenye yomgogodla iyancibilika nakanjani, okwenza kube nzima ukulawula ubukhulu bodonga lwangaphakathi lwe-multifold .Eminyakeni yamuva nje, ngenxa yokuthuthukiswa kobuchwepheshe bokushisela ukudlidliza, ubuchwepheshe bokushisela bobukhulu obukhulu bengilazi obuqiniswe nge-PA66 buya ngokuya buvuthwa.

Ngenxa yalesi sizathu, i-manifold ingabunjwa ibe yizicucu ezimbili zezingxenye eziningi, ezihlanganiswe nge-vibration welding.Iningi labakhiqizi bezimoto emhlabeni njengamanje basebenzisa le ndlela ukuze bakhiqize ama-multifolds, ama-plasticizing metal manifolds.
