I-Bumper iyithuluzi lokuphepha elithatha futhi linciphise umthelela wangaphandle futhi livikele ngaphambili nangemuva lomzimba wemoto. Eminyakeni engamashumi amabili edlule, ama-bumpers angaphambili nangemuva wezimoto ayenziwa ikakhulukazi ngezinto zensimbi. Bagxinyelwe insimbi ye-u-hanber enobukhulu be-3mm. Ingaphezulu laliphathwa nge-Chrome futhi livuswe noma lifakwe ndawonye ngesitimela sohlaka. Ngokuthuthukiswa komkhakha wezimoto, i-automobile bumper njengedivaysi ebalulekile yokuphepha nayo isendleleni yokuqamba. Ama-bumpers emoto yanamuhla kanye nama-bumpers angemuva ngaphezu kokugcina umsebenzi wokuqala wokuvikela, kodwa futhi nokuphishekela ukuvumelana nobunye ngesimo somzimba, ukuphishekela umuzwa wawo ongasindi. Ukufeza le njongo, ama-bumpers angaphambili nawangemuva ezimoto zenziwe ngopulasitiki, ezaziwa ngokuthi ama-bumpers epulasitiki. I-bumper yepulasitiki yakhiwa izingxenye ezintathu, njengepuleti yangaphandle, impahla ye-cushioning kanye nogongolo. Ipuleti yangaphandle kanye nokudla kwe-buffer kwenziwa ngopulasitiki, kanti nogongolo lwenziwe ngephepha elibandayo elibandayo elinobukhulu obungama-1.5 mm futhi ligxivizwa kwi-groove ebekiwe; Ipuleti yangaphandle kanye nokuqukethwe kwe-cushioning kunamathiselwe ku-beam, okunamathiselwe kwisikulumo sesitimela sohlaka futhi kungasuswa nganoma yisiphi isikhathi. Lolu hlobo lwe-bumper yepulasitiki lusebenzisa ipulasitiki, ngokuyisisekelo lusebenzisa uchungechunge lwe-polyester kanye nochungechunge lwe-polypropylene lwezinto zokwakha ezimbili, usebenzisa indlela yokubumba yomjovo. Kwelinye izwe kukhona nohlobo lwepulasitiki olubizwa ngePolycarbon Eder, ukungena ku-Alloy Ukuhlanganiswa, ukucubungula inzuzo yokuqina, futhi futhi kunezinzuzo zokufudumala, kanye nokusebenza okuphezulu kwemoto. I-bumper yepulasitiki inamandla, ukuqina kanye nomhlobiso, ukusuka endaweni yokuphepha, ukushayisana kwezimoto kungadlala umzimba we-buffer, kuvikeleke ngokwemvelo, kube yingxenye enhle yokuhlobisa izimoto.
