1. Kev hnav siab hnyav, yog tias pwm tsis hnav tsis tau, nws yog ib qho yooj yim uas ua rau hnoos ntev heev ntawm qhov kab noj hniav.
2. Cov tshuaj tiv thaiv ua kom muaj zog, ntau yam khoom ntawm plastics, xws li cov nplaim hluav taws, txawm tias cov tshuaj tua tau ntawm nws lub peev xwm yuav ua rau cov kab tsuag pwm.
3. Kub thermal conductivity, zoo pwm kub tswj tau zoo kawg rau lub zog ntawm cov yas txhaj tshuaj thaum lub sij hawm txhaj molding, tshwj xeeb tshaj yog thaum ua cov semi-crystalline thermal yas xeem.Generally, tooj hlau alloy muaj zoo thermal conductivity dua tooj liab hlau, tab sis nws elastic modulus, hardness thiab durability yog tsawg dua.Tus thermal conductivity ntawm hlau tau compensated los ntawm qhov system txias.
4. Kev ruaj ntseg zoo, ua haujlwm ntawm pwm cov pwm, pwm cov kab noj hniav thaum ua kom sov kub kom ncav ntau dua 300 degree, qhov txawv ntawm qhov txawv yog qhov loj, yooj yim los ua qhov hloov me me hloov degradation, yog li zhao pwm me me hloov, ua cov khoom yas yog tsis ruaj khov.
5. Kev siv hlau nplaum yog qhov zoo, kev thov siab tshaj plaws rau sab hauv txheej ntawm lub puab pwm thaum curing, qhov roughness tsawg heev, los hloov qhov kev xav tau ntawm cov plastics nto glossiness zoo, rau qhov no, feem ntau qhov kab noj hniav yuav tsum muaj nyob rau hauv kev ua polishing, raws li ci li tau, yog li ntawd, thov pwm cov ntaub ntawv yog yooj yim rau txhuam, yog li xaiv cov khoom yuav tsum tsis txhob muaj impurities thiab xws li porosity.
