Polyurethane castingyog cov txheej txheem tsim khoom siv dav siv hauv kev lag luam automotive nrog rau ntau lwm yam kev lag luam. Cov txheej txheem cuam tshuam nrog kev nchuav lossis casting kua polyurethane tshuab rau hauv pwm qhov chaw uas lawv hnov mob, kho, thiab tsim cov khoom elastomeric. Vim nws qhov yooj yim hauv kev tsim thiab ua tiav, polyurethane casting tuaj yeem tsim cov khoom nrog ntau yam khoom siv, qib hardness, thiab cov yam ntxwv ntawm cov qauv. Qhov no ua rau nws tsim nyog rau kev tsim cov khoom lag luam uas yuav tsum tau tiv thaiv kev ntxhov siab, kev puas tsuaj, thiab kev nyuaj ib puag ncig.
Cov ntaub ntawv polyurethane nquag siv los tsim ntau yam kev lag luam xws li scrapers, shock absorbers, stamping plates, channel steel Cheebtsam, thiab ntim. Tsis tas li ntawd, cov txheej txheem casting feem ntau yog siv rau hauv kev tsim cov khoom sib khi, bushings, bearings, thiab lwm yam khoom siv uas yuav tsum tau ua kom muaj zog thiab muaj zog. Cov khoom no feem ntau ua haujlwm nyob rau hauv ib puag ncig uas cov khoom siv xws li roj hmab lossis cov yas yas yuav ua tsis tau ntxov ntxov vim hnav, deformation, lossis raug tshuaj lom neeg.
Ib qho ntawm cov laj thawj tseem ceeb ntawm polyurethane casting yog suav tias yog kev lag luam zoo nkauj yog nws qhov kev hloov pauv hauv pwm tsim thiab cov nplais ntau lawm. Polyurethane casting pwm tuaj yeem tsim nyob rau hauv ntau qhov ntau thiab tsawg thiab kev teeb tsa. Qhov kev hloov pauv no tso cai rau cov tuam txhab tsim cov khoom nrog txhua qhov geometric complexity thiab hnyav ntau. Los ntawm me me precision Cheebtsam mus rau loj industrial qhov chaw, polyurethane casting tshuab tuaj yeem ua raws li cov khoom sib txawv yam tsis tas yuav tsum muaj cov cuab yeej siv ntau dhau.
Lwm qhov txiaj ntsig tseem ceeb ntawm cov ntaub ntawv polyurethane yog lawv lub peev xwm los tswj kev ua haujlwm ruaj khov thoob plaws qhov kub thiab txias. Ntau cov polyurethane elastomers tuaj yeem ua haujlwm tau zoo nyob rau hauv ob qho tib si qis thiab nruab nrab qhov kub thiab txias ib puag ncig yam tsis muaj qhov poob ntawm txhua yam muaj zog lossis elasticity. Qhov ntsuas kub no nthuav dav lawv cov kev siv tau hauv kev lag luam uas muaj qhov sib txawv ntawm cov thermal fluctuations.
Polyurethane cam khwb cia qhov chaw kuj ua rau pom muaj zog tiv thaiv kev sib kis, corrosion, thiab kev puas tsuaj. Tsis zoo li qee cov hlau uas tuaj yeem corrode nyob rau hauv qhov chaw ntub dej los yog tshuaj lom neeg, cov ntaub ntawv polyurethane feem ntau pom muaj tshuaj lom neeg zoo. Lawv tiv taus cov roj, cov kuab tshuaj, thiab ntau yam khoom siv tshuaj, uas ua rau lawv haum rau siv hauv tshuab, khoom siv, thiab kev thauj mus los. Tsis tas li ntawd, cov khoom siv polyurethane tsis tshua muaj qhov degradation thaum raug cov plua plav, ya raws, lossis lwm yam kab mob ib puag ncig.
