I-bumper sisixhobo sokhuseleko esifunxayo kwaye sinciphise impembelelo yangaphandle kwaye sikhusela umphambili kunye nomva womzimba wemoto. Kwiminyaka engamashumi amabini eyadlulayo, iibumpers zemoto zangaphambili nasemva zazenziwe ikakhulu ngezinto zentsimbi. Baye bagximfizwa kwintsimbi ye-U-shaped channel ene-thickness engaphezu kwe-3 mm, kwaye umphezulu waphathwa nge-chromium. Zazidityaniswe okanye zidityaniswe kunye nomqadi welongitudinal wefreyimu, kwaye kwakukho umsantsa omkhulu nomzimba, ngokungathi yinxalenye eqhotyoshelweyo. Ngophuhliso loshishino lweemoto, ibumper yemoto njengesixhobo esibalulekileyo sokhuseleko ikwasendleleni yokuqalisa izinto ezintsha. Imoto yanamhlanje ngaphambili kunye ne-bumpers yangasemva ukongeza ekugcineni umsebenzi wokukhusela wokuqala, kodwa kunye nokusukela imvisiswano kunye nobunye kunye nokumila komzimba, ukusukela ukukhanya kwayo. Ukufezekisa le njongo, ii-bumpers zemoto zangaphambili nasemva zenziwe ngeplastiki, ezaziwa ngokuba zii-bumpers zeplastiki. I-bumper yeplastiki yenziwe ngamacandelo amathathu: ipleyiti yangaphandle, i-cushioning material kunye nomqadi. I-plate yangaphandle kunye ne-buffer material yenziwe ngeplastiki, kwaye i-boam yenziwe ishidi elipholileyo elinobunzima obumalunga ne-1.5 mm kwaye lenziwe kwi-groove e-U-shaped; I-plate yangaphandle kunye nezinto zokucoca zifakwe kwi-boam, efakwe kwi-screws ye-rail frame kwaye inokususwa nanini na. Le bumper yeplastiki isebenzisa iplastiki, ngokusisiseko isebenzisa iindidi ezimbini zemathiriyeli, ipolyester kunye ne-polypropylene, isebenzisa indlela yokubumba inaliti. Kukwakho uhlobo lweplastiki ebizwa ngokuba yi-polycarbon ester series phesheya, ukungena kwi-alloy composition, indlela yokubumba inaliti ye-alloy, ukusetyenzwa ngaphandle kwe-bumper akugcini nje ngokuba namandla aphezulu, kodwa kunenzuzo ye-welding, kunye nokusebenza kokugquma kulungile, ubuninzi bobuninzi nangaphezulu emotweni. Ibhampa yePlastiki inamandla, ukuqina kunye nokuhombisa, ukusuka kwindawo yokhuseleko lwembono, ingozi yongquzulwano lwemoto inokudlala indima yesithinteli, ikhusele umzimba wemoto yangaphambili nangasemva, ukusuka kwinkangeleko yembono, inokudityaniswa ngokwemvelo kunye nomzimba kwiqhekeza, lilonke, linomhombiso olungileyo, libe yinxalenye ebalulekileyo yenkangeleko yemoto yomhombiso.
