Hauv automotive xeem tsim kev lag luam, roto - molding siv nyob rau hauv kev tsim roj thiab hnab looj tes muaj zog, thiab cov nqi tswj tau. Txawm li cas los xij, cov qauv kev tsim kho rau automotive roto {2} moulded qhov cuam tshuam cuam tshuam los cuam tshuam cov khoom zoo thiab yuav tsum nruj me ntsis rau cov cai kev lag luam.
Ua ntej, cov khoom siv raw yog qhov tseem ceeb heev. Automotive roto {{1} moulded feem feem ntau siv high {2} yuav tsum muaj huab cua polyepropylene (pp) lossis hloov kho, thiab tshuaj lom neeg muaj peev xwm. Suppliers must provide material certification that complies with international standards (such as ISO or ASTM) to ensure that the materials meet automotive-grade application requirements.
Thib ob, pwm tsim thiab cov tshuab ua kom ncaj ncaj qha cuam tshuam ncaj qha cuam tshuam cov khoom tiav qhov ntev thiab lub zog muaj zog. Roto {- molding pwm yuav tsum tso cai rau cov shrinkage txaus (feem ntau 3% -5%) los tiv thaiv cov khoom deformation thiab pwm-los tiv thaiv cov khoom deformation thiab pwm. Ntxiv mus, pwm nto kev kho mob (xws li polishing lossis txheej) tuaj yeem txo cov khoom nplaum thiab txhim kho ntau dua.
Thaum lub sij hawm tsim qauv, tswj qhov kub thiab kev sib hloov ceev yog qhov tseem ceeb. Lub tshuab rompolding yuav tsum yog tusyees rhuab rau cov khoom siv kub yaj (feem ntau 200℃-280 degree) los xyuas kom meej cov lus nplaum uas tsis muaj pwm ntawm cov pwm sab hauv. Lub sijhawm cua sov thiab tus nqi cua txias yuav tsum tau ua kom meej kom tsis txhob muaj kev ntxhov siab sab hauv los ntawm kev txias ntau dhau.
Thaum kawg, cov khoom tiav undergoes nruj nrees Kuaj, suav nrog phab ntsa thickness uniformity kev sim, cuam tshuam lub zog kev kuaj, thiab pov thawj foob. Cov qauv kev lag luam feem ntau yuav tsum muaj lub phab ntsa thickness sib txawv ntawm tsis muaj ntau tshaj ± 5%, thiab ua raws li cov kev tshwj xeeb oems.
Mastering Cov Qauv Kev Siv no tsis tsuas yog txhim kho cov khoom lag luam zoo ntawm cov khoom siv hluav taws xob tab sis kuj txhim kho kev sib tw hauv kev ua lag luam thoob ntiaj teb. Cov kws qhia kev lag luam tawm txawv teb yuav tsum saib xyuas cov kev lag luam kom ntseeg tau tias lawv cov khoom lag luam raws li cov kev xav tau ntawm cov neeg siv khoom hauv ntiaj teb.
