Cov txheej txheem thiab kev tiv thaiv ntawm cov xim tsis sib xws ntawm cov khoom kub xovxwm:

① Cov pwm kub tsis sib xws, thiab qhov siab dhau lawm. Cov pwm kub yuav tsum tau tswj kom zoo;

② Tsis zoo fluidity ntawm cov khoom molding, ua rau cov fiber ntau tsis sib xws, feem ntau tuaj yeem ua rau lub siab molding kom nce qhov fluidity ntawm cov yaj;

③Pigment thiab resin tsis tuaj yeem sib xyaw zoo hauv cov txheej txheem ntawm cov xim muab tshuaj txhuam.
