Lub tsheb bumper yog ib qho ntawm cov khoom siv loj dua ntawm lub tsheb, nws muaj peb lub luag haujlwm tseem ceeb: kev nyab xeeb, kev ua haujlwm thiab kho kom zoo nkauj.
Muaj peb txoj hauv kev tseem ceeb ntawm lub tsheb bumper lub teeb yuag: cov khoom siv lub teeb yuag, kev txhim kho cov qauv tsim thiab kev tsim cov txheej txheem kev tsim kho tshiab.Cov khoom hnyav feem ntau yog hais txog kev hloov cov khoom qub nyob rau hauv tej yam kev mob, xws li yas rau hlau;bumper lightweight qauv optimization tsim mas muaj nyias-phab ntsa tshuab;cov txheej txheem tsim khoom tshiab muaj cov khoom siv micro-foam thiab cov pa roj auxiliary molding thiab lwm yam thev naus laus zis tshiab.
Yas bumper cov khoom xaiv yas vim lub teeb pom kev zoo, kev siv zoo, kev tsim khoom yooj yim, kev tiv thaiv corrosion, cuam tshuam tsis kam, tsim kev ywj pheej thiab lwm yam ntxwv, yog dav siv hauv kev lag luam tsheb, thiab feem ntau ntawm cov khoom siv tsheb.Tus nqi ntawm cov yas siv rau ntawm lub tsheb tau dhau los ua ib qho ntawm cov qauv ntsuas kev txhim kho ntawm lub teb chaws kev lag luam tsheb.Tam sim no, cov teb chaws tsim los tsim lub tsheb rau kev siv cov yas tau mus txog 200kg, suav txog li 20% ntawm cov tsheb zoo.
Yas nyob rau hauv Tuam Tshoj txoj kev lag luam tsheb yog daim ntawv thov lig, tus nqi ntawm cov yas hauv kev lag luam tsheb tsuas yog 50 ~ 60kg, cov tsheb laus muaj 60 ~ 80kg, qee lub tsheb tuaj yeem ncav cuag 100kg, Tuam Tshoj hauv kev tsim cov tsheb thauj khoom nruab nrab, txhua lub tsheb nrog txog 50 kg ntawm yas.Txhua lub tsheb siv yas rau 5 mus rau 10 feem pua ntawm lub tsheb qhov hnyav.
Bumper cov ntaub ntawv feem ntau muaj cov cai hauv qab no: kev cuam tshuam zoo, huab cua tsis zoo.Cov xim zoo nkauj txuas muaj peev xwm, fluidity zoo, kev ua haujlwm zoo, tus nqi qis.Raws li, PP cov ntaub ntawv hauv chav kawm yog qhov tsis muaj qhov tsis ntseeg qhov kev xaiv zoo dua.PP cov ntaub ntawv yog ib yam ntawm cov yas yas uas muaj kev ua tau zoo, tab sis PP nws tus kheej muaj kev ua haujlwm tsis zoo ntawm qhov kub thiab qhov cuam tshuam, tsis hnav tsis kam, kev laus yooj yim thiab tsis zoo, yog li hloov PP feem ntau yog siv los ua cov khoom siv hauv tsheb.Tam sim no, polypropylene automotive bumper cov ntaub ntawv tshwj xeeb feem ntau yog PP raws li cov khoom tseem ceeb, thiab ntxiv ib qho kev faib ua feem ntawm roj hmab los yog elastomer, inorganic muab tub lim, xim niam hais, additives thiab lwm yam ntaub ntawv tom qab sib tov thiab ua tiav.
Nws yog ib qho yooj yim los ua warping deformation, uas yog tshwm sim los ntawm sab hauv kev ntxhov siab tso tawm.Nyias-walled bumpers ua rau muaj kev ntxhov siab nyob rau hauv ntau theem ntawm kev txhaj tshuaj molding.
Feem ntau, nws feem ntau suav nrog kev taw qhia kev ntxhov siab, thermal stress thiab pwm tso tawm kev ntxhov siab.Orientation kev ntxhov siab yog qhov kev nyiam sab hauv uas tshwm sim los ntawm cov fibers, macromolecular chains los yog saw segments nyob rau hauv lub yaj yog oriented nyob rau hauv ib tug tej yam kev taw qhia thiab tshwm sim los ntawm tsis txaus so.Cov kev taw qhia muaj feem xyuam rau cov khoom thickness, yaj kub, pwm kub, txhaj tshuaj, thiab lub sij hawm tuav lub siab.Qhov siab dua qhov tuab, qhov qis dua qhov taw qhia;qhov kub ntawm melting ntau dua, qhov qis dua qhov taw qhia, qhov qis dua qhov taw qhia;qhov siab dua qhov txhaj tshuaj, qhov siab dua qhov kev taw qhia;ntev lub sij hawm tuav lub siab, qhov ntau dua qhov taw qhia.
Thermal stress yog vim qhov kub ntawm cov pwm pwm thiab qhov kub thiab txias ntawm pwm, thiab qhov kub ceev ntawm cov yaj hauv qhov chaw ze ntawm cov pwm kab noj hniav.Kev tso tawm kev ntxhov siab feem ntau yog vim qhov tsis txaus lub zog thiab nruj ntawm cov pwm, elastic deformation nyob rau hauv qhov kev txiav txim ntawm kev txhaj tshuaj siab thiab tso tawm sab saum toj, thiab qhov kev faib tawm tsis tsim nyog ntawm cov khoom lag luam tsis sib xws.Lub bumper nyias phab ntsa kuj yuav nyuaj.Vim hais tias cov phab ntsa thickness gauge me me thiab muaj ib tug me me shrinkage, cov khoom yog nruj nreem adhered rau cov pwm;lub siab tuav lub sij hawm tswj yog ib qho nyuaj, thiab lub nyias phab ntsa thickness thiab reinforcement yog yooj yim puas.Ib txwm qhib pwm yuav tsum tau lub koob txhaj tshuaj los muab pwm qhib lub zog txaus, uas yuav tsum muaj peev xwm kov yeej qhov kev tawm tsam ntawm kev qhib pwm.
Muaj ob peb yam teeb meem uas yuav tsum tau kov yeej hauv cov txheej txheem ntawm pwm qhib
Ua ntej ntawm tag nrho cov, nws yog ib qhov tsim nyog los kov yeej lub zog qhib ncaj qha.Thaum lub pwm qhib, cov yas yuav muaj qee qhov adhesion quab yuam thaum uas tig mus rau qhov qhib kev taw qhia, uas yog vim qhov txias ntawm cov khoom yas thaum pwm txias tsis txaus, thiab elastic expansion ntawm hom kab noj hniav tsis zoo tag nrho.Qhov loj ntawm qhov adhesion quab yuam yog muaj feem xyuam rau qhov zoo ntawm cov yas, qhov zoo ntawm cov pwm, txoj kab nqes ntawm cov pwm, thiab lwm yam. Tsis tas li ntawd, nws yog ib qho tsim nyog yuav tsum tau kov yeej cov pwm qhib qhov tsis ncaj, uas yog, sab motorized. core extraction txheej txheem.Nws tseem yog ib qho tsim nyog los kov yeej qhov kev sib txhuam tsis sib haum los ntawm kev txav ntawm cov pwm txav thiab cov qauv kev ua haujlwm.Tom qab ntawd nws yog ib qho tsim nyog yuav tsum tau kov yeej qhov kev koom tes siab ntawm cov kab noj hniav, thaum lub siab ntawm cov kab noj hniav yuav tsis sib npaug ntawm qhov siab ntawm atmospheric, thiab lub siab nyob rau hauv cov kab noj hniav tsis sib npaug rau sab nraud.
Txhawm rau daws cov teeb meem loj saum toj no, kev tsim pwm yuav tsum tau txhim kho kom tsim nyog.Xaiv cov khoom pwm tsim nyog los txhim kho pwm thermal zog thiab hnav tsis kam.Tsim nyog pwm qauv tsim thiab tsim, tsim nyog nce lub thickness ntawm lub laub phaj thiab nruab nrab ncoo phaj, txhim kho qhov tawv nqaij ntawm pwm, txo cov elastic deformation ntawm pwm.Txhim kho kev tsim khoom thiab kev sib koom ua haujlwm raug ntawm cov tub ntxhais extraction mechanism thiab cov lus tsa suab, txo qhov roughness ntawm hom kab noj hniav, core thiab convex module Cheebtsam, thiab txo cov pwm tso tawm quab yuam.Nrog rau kev tsim qauv siab dua thiab kev sib raug zoo uas yuav tsum tau ua, cov cuab yeej txuas feem ntau yog muab los tiv thaiv cov txheeb ze ntawm cov tub ntxhais tuag thiab cov kab noj hniav tuag.Cov txheej txheem pouring yuav tsum tau tsim kom zoo, thiab cov dej ntws channel tsim yuav tsum siv cov khoom yas los ntawm cov cheeb tsam tuab mus rau qhov chaw thinner thaum txhaj tshuaj.Kuj tseem yuav tsum muaj cov chaw nres nkoj txaus.Nyob rau hauv cov nqe lus ntawm kev txhaj tshuaj, qhov kev ntxhov siab sab hauv ntawm cov khoom yas yuav tsum raug txo kom tsawg, thiab kev txhaj tshuaj ceev thiab qhov txias txias yuav tsum raug txo.Ua kom kub yaj thiab pwm kub yog li ntawd yuav tsum tau so kom txaus.Kev txhaj tshuaj tsim nyog, lub sijhawm tuav lub sijhawm, thiab lub sijhawm txias kuj tseem xav tau.Huangyan Leiao Molding Co., Ltd. nyob hauv Huangyan District pwm lub nroog, Taizhou, Taizhou xeev, uas yog "Lub nroog ntawm Suav pwm".Lub tuam txhab feem ntau yog koom nrog kev txhaj tshuaj pwm tsim, muaj ntau xyoo ntawm kev tsim pwm, feem ntau yog tsim thiab ua lub raj mis embryo pwm, PET khoom pwm, lub raj mis cap pwm, lub tsheb sab hauv thiab sab nrauv kho kom zoo nkauj pwm……. pwm system muaj nws tus kheej tshwj xeeb tsim thiab ua tshuab, raws li lub tswvyim ntawm "Kev Tswj Xyuas Kev Ncaj Ncees", nrog rau cov neeg siv khoom hauv tsev thiab txawv teb chaws los tsim kom muaj kev sib raug zoo ntawm kev koom tes ntev, Kuv ntseeg tias Leiao yuav yog koj tsim nyog ntawm kev ntseeg siab hauv kev koom tes. kev lag luam.
