Cov khoom muaj cov cim ntws
Cov cim ntws yog cov cim ntawm kev ntws ntawm cov khoom siv molten, nrog cov kab txaij tshwm sim ntawm qhov chaw nruab nrab ntawm lub rooj vag.
Cov cim ntws yog tshwm sim los ntawm kev txias sai ntawm cov khoom uas thaum xub thawj ntws mus rau hauv qhov chaw tsim khoom, thiab tsim kom muaj ciam teb ntawm nws thiab cov khoom uas tom qab ntawd ntws mus rau hauv nws. Txhawm rau tiv thaiv cov cim ntws, qhov kub ntawm cov khoom tuaj yeem nce ntxiv, cov khoom siv dej tuaj yeem txhim kho, thiab qhov ceev ntawm kev txhaj tshuaj tuaj yeem hloov kho.
Yog tias cov khoom txias uas tseem nyob ntawm qhov kawg ntawm lub nozzle ncaj qha nkag mus rau hauv qhov chaw tsim khoom, nws yuav ua rau muaj cov cim ntws. Yog li ntawd, kev teeb tsa cov chaw lagging txaus ntawm qhov sib tshuam ntawm sprue thiab tus khiav, lossis ntawm qhov sib tshuam ntawm tus khiav thiab splitter, tuaj yeem tiv thaiv tau zoo kom tsis txhob muaj cov cim ntws. Tib lub sijhawm, qhov tshwm sim ntawm cov cim ntws kuj tseem tuaj yeem tiv thaiv tau los ntawm kev nce qhov loj ntawm lub rooj vag.
