Bumper nigikoresho cyumutekano gikurura kandi gigabanya ingaruka zo hanze kandi kirinda imbere ninyuma yumubiri wimodoka. Imyaka 20 irashize, ibibyimba byimbere ninyuma byimodoka byakozwe ahanini nibikoresho by'ibyuma. Bashyizwe mu kajagari u-humura umubyimba ufite ubunini bwa mm irenze 3, kandi ubuso bwafashwe na chromium. Barizengurutse cyangwa basudikuwe hamwe nigitaramo kirekire cyikadiri, kandi hari icyuho kinini hamwe numubiri, nkaho ari igice. Hamwe niterambere ryinganda zimodoka, bumper yimodoka nkigikoresho cyumutekano nacyo kiri kumuhanda uhangayika. Uyu munsi imodoka imbere ninyuma yinyongera usibye gukomeza imikorere yambere yo kurinda, ariko no gukurikirana ubwuzuzanye nubumwe n'imiterere yumubiri, gukurikirana umubiri wacyo. Kugirango ugere kuri iyi ntego, ibibyimba byimbere hamwe ninyuma byimodoka bikozwe muri plastike, bizwi nka bumpers. Bumper ya plastike igizwe n'ibice bitatu: isahani yo hanze, ibikoresho byo mu nkoko no mu kiraro. Isahani yo hanze hamwe nibikoresho bya buffer bikozwe muri plastiki, kandi igiti gikozwe mu mpapuro zikonje zifite ubunini bwa mm igera kuri 1.5 kandi ikorwa muri gm u-shusho; Ibikoresho byo hanze nibikoresho byometseho bifatanye nicyo kibeshyi, bifatanye kumurongo wa gari ya moshi kandi urashobora kuvaho igihe icyo aricyo cyose. Iyi miyoboro ya plastike ikoresha plastike, ahanini ukoresheje ubwoko bubiri bwibikoresho, polyester na polypropylene, ukoresheje uburyo bwo kubumba. There is also a kind of plastic called polycarbon ester series abroad, infiltration into the alloy composition, the alloy injection molding method, processing out of the bumper not only has high strength rigidity, but also has the advantage of welding, and the coating performance is good, the amount of more and more in the car. Bumper ya plastike afite imbaraga, iyobowe nuburiganya, uhereye kumutekano wimodoka, kurinda umubiri wimodoka, urinde umubiri wimodoka. Muburyo bwimodoka
