I-car bumper iyithuluzi lokuphepha elimunca futhi linciphise umthelela wangaphandle futhi livikele ingaphambili nangemuva komzimba wemoto. Idivayisi ekhiqiza ukugoqa lapho imoto noma umshayeli ephoqeleka ukushayisana. I-plastic bumper yakhiwe ngepuleti langaphandle, izinto zokugoqa kanye nogongolo oluphambene. Ipuleti langaphandle nezinto zokugoqa zenziwe ngepulasitiki, kanti ugongolo oluphambene lugxivizwe ngeshidi eligoqekile elibandayo elinobukhulu obungaba ngu-1.5mm ukuze kwakheke umsele omise okwe-U; Ipuleti langaphandle nezinto zokugoqa zinamathiselwe kugongolo oluphambene, oluxhunywe nogongolo olude lohlaka ngezikulufo futhi lungasuswa nganoma yisiphi isikhathi. Ipulasitiki esetshenziswa kule bumper yepulasitiki ngokuvamile yenziwe ngezinto ze-polyester ne-polypropylene ngokufaka umjovo. I-car bumper iyithuluzi lokuphepha elimunca futhi linciphise umthelela wangaphandle futhi livikele izingxenye zangaphambili nangemuva zomzimba wemoto. Eminyakeni engamashumi amabili edlule, ama-bumper angaphambili nangemuva ezimoto ayenziwe kakhulu ngezinto zensimbi. Agxivizwa ensimbini yesiteshi enobukhulu obungaphezu kuka-3mm. Ubuso babufakwe i-chrome, buboshwe noma buhlanganiswe ngomsebe wohlaka olude, futhi kwakukhona igebe elikhulu nomzimba, okwakubonakala sengathi kuyingxenye eyengeziwe. Ngokuthuthuka kwemboni yezimoto, i-automobile bumper, njengedivayisi ebalulekile yokuphepha, nayo isendleleni yokusungula izinto ezintsha. Ama-bumper angaphambili nangemuva ezimoto zanamuhla awagcini nje ngokugcina umsebenzi wokuqala wokuvikela, kodwa futhi aphishekela ukuvumelana nobunye nesimo somzimba, futhi aphishekela okulula kwawo. Ukuze kufezwe lo mgomo, ama-bumper angaphambili nangemuva ezimoto enziwe ngepulasitiki, ebizwa ngokuthi i-plastic bumper. I-plastic bumper yakhiwe ngepuleti langaphandle, izinto zokusika kanye nomsebe wokweqa. Ipuleti langaphandle kanye nezinto zokweqa zenziwe ngepulasitiki, kanti umsebe wokweqa ugxivizwe ngeshidi eligoqiwe elibandayo elinobukhulu obungaba ngu-1.5mm ukuze kwakheke umsele omise okwe-U; Ipuleti langaphandle nezinto zokweqa zinamathiselwe kumsebe wokweqa, oxhunywe nomsebe wokweqa wohlaka ngezikulufo futhi ungasuswa nganoma yisiphi isikhathi. Ipulasitiki esetshenziswa kule bumper yepulasitiki ngokuvamile yenziwe ngezinto ze-polyester ne-polypropylene ngokufaka umjovo. Kukhona nohlobo lwepulasitiki olubizwa ngokuthi uhlelo lwe-polycarbonate phesheya, olungena ngaphakathi kwe-alloy composition bese lusebenzisa indlela yokubumba i-alloy injection. I-bumper ecutshunguliwe ayigcini nje ngokuba nokuqina okunamandla aphezulu, kodwa futhi inezinzuzo zokushisela, kodwa futhi isebenza kahle ekumbozeni, futhi isetshenziswa kakhulu ezimotweni. I-bumper yepulasitiki inamandla, ukuqina kanye nokuhlobisa. Ngokombono wokuphepha, ingadlala indima ye-buffer uma kwenzeka ingozi yokushayisana futhi ivikele umzimba wangaphambili nowangemuva. Ngokombono wokubukeka, ingahlanganiswa ngokwemvelo nomzimba futhi ibe yinto ephelele. Inokuhlobisa okuhle futhi isibe yingxenye ebalulekile yokuhlobisa ukubukeka kwemoto.
