Lamination txheej txheem molding txoj kev. Nws yog hais txog ib txoj kev molding uas ua ke nrog ntau txheej txheej ntawm tib los yog sib txawv cov ntaub ntawv nyob rau hauv cua sov thiab siab. Nws feem ntau yog siv rau hauv kev ua cov yas thiab tseem ua cov roj hmab. Hauv kev ua cov yas, rau cov yas thermoplastic, feem ntau yog siv los tsim cov khoom siv tawv tawv lossis cov yeeb yaj kiab sib xyaw; rau cov thermosetting plastics, nws yog ib txoj hauv kev tseem ceeb rau kev tsim cov yas thiab cov khoom siv ntxiv. Cov ntaub ntawv txhawb zog xws li ntawv, ntaub, iav ntaub, tshwj xeeb fibers, thiab lwm yam. impregnated nrog thermosetting resin yog stacked, rhuab thiab pressurized kom tau ntau yam khoom laminated, xws li laminated boards. Hauv kev ua cov roj hmab, cov roj hmab superimposed thiab ntaub tuaj yeem laminated rau hauv tapes.
Lamination tuaj yeem muab faib ua cov txheej txheem siab (high-pressure txheej molding) thiab cov txheej txheem tsis tshua muaj siab (tsawg-siab lamination molding) raws li kev ua haujlwm siab.
Lamination molding txheej txheem yog qhib pwm molding txoj kev rau cov khoom sib xyaw. Cov txheej txheem no tau tsim ua ntej thiab paub tab ntau dua. Nws cov yam ntxwv yog cov khoom zoo, cov txheej txheem ruaj khov, thiab tsis tshua muaj pwm peev. Nws qhov tsis zoo yog tias nws tsuas tuaj yeem tsim cov phaj tiaj tus, nkhaus daim hlau, thiab lwm yam.
Txawm li cas los xij, piv nrog cov ntawv extruded, cov ntawv laminated tseem muaj qhov zoo uas cov nplooj ntawv extruded tsis tuaj yeem hloov tau: cov ntawv laminated tuaj yeem tsim nrog lub thickness ntawm 2 mus rau 50 hli, thaum lub thickness ntawm domestic extruded nplooj ntawv yog nruab nrab ntawm 2 thiab 20 hli, thiab cov nplooj ntawv saum toj no 20. mm tsuas yog tsim los ntawm lamination. Yog li ntawd, txawm hais tias cov txheej txheem lamination yog ntev thiab kev siv hluav taws xob siab, nws tseem yog ib txoj hauv kev tsim khoom tseem ceeb.
