Raws li cov extruder yog ua los ntawm cov hlau uas muaj siab hardness, nws yuav raug kev co cuam tshuam thiab lwm yam sib xyaw quab yuam thaum lub sij hawm tsim khoom thiab kev ua haujlwm, ua rau kev tshem tawm thiab hnav ntawm cov khoom.
Cov txheej txheem kho ib txwm muaj xws li surfacing, thermal spraying, txhuam hla, thiab lwm yam, tab sis ob peb txoj kev muaj qee qhov tsis zoo: surfacing yuav ua rau saum npoo ntawm qhov chaw ncav cuag qhov kub thiab txias, ua rau deformation lossis tawg, cuam tshuam rau qhov tseeb qhov tseeb thiab kev siv ib txwm, thiab txawm ua rau pob txha hauv qhov mob hnyav; Txawm hais tias txhuam ferry tsis muaj thermal nyhuv, lub thickness ntawm ferry txheej tsis tuaj yeem tuab heev, cov pa phem yog qhov hnyav, thiab daim ntawv thov kuj tseem txwv. Hauv cov teb chaws sab hnub poob, cov khoom siv polymer yog dav siv los daws cov teeb meem saum toj no. Nws cov kev ua tau zoo thiab kev ua haujlwm tau zoo txhua lub sijhawm tuaj yeem ua tau raws li qhov yuav tsum tau ua ntawm kev pabcuam thiab raug tom qab kho, txo qhov cuam tshuam thiab kev vibration los ntawm cov khoom siv hauv kev ua haujlwm thiab ua kom lub neej ntev.
