Iyini i-bumper engaphambili?
Ipuleti langaphandle kanye nezinto ezihlanganisiwe zenziwe ngepulasitiki, kanti ugongolo oluphambene lugxivizwa emseleni omise okwe-U oneshidi eligoqwe ngokubandayo elinobukhulu obungaba ngu-1.5mm; Ipuleti langaphandle kanye nezinto ezihlanganisiwe zinamathiselwe emsebeni ophambene, oxhunywe nomsebe wobude bohlaka ngezikulufo futhi ungasuswa nganoma yisiphi isikhathi. Ipulasitiki esetshenziswa kule bumper yepulasitiki ngokuvamile yenziwe nge-polyester kanye ne-polypropylene ngokufaka injection molding. Isibonelo, i-bumper yemoto yePeugeot 405 yenziwe ngezinto ezihlanganisiwe futhi yenziwe ngokufaka injection molding. Ama-bumper e-Audi 100 yeVolkswagen, igalofu, iSantana eShanghai kanye neXiali eTianjin enziwe ngezinto ezihlanganisiwe nge-injection molding. Kukhona nohlobo lwepulasitiki olubizwa ngokuthi uhlelo lwe-polycarbonate kwamanye amazwe, olungena ezingxenyeni ze-alloy futhi lusebenzise indlela yokufaka injection molding ye-alloy. I-bumper ecutshunguliwe ayinayo nje kuphela ukuqina okunamandla aphezulu, kodwa futhi inezinzuzo zokushisela, kodwa futhi isebenza kahle ekumbozeni, futhi isetshenziswa kakhulu ezimotweni.
I-geometry ye-bumper akumele ihambisane nesimo semoto yonke ukuqinisekisa ubuhle, kodwa futhi ihambisane nezici zomshini kanye nezici zokumunca amandla ukuqinisekisa ukumunca nokudlidliza ngesikhathi sokushaya.
