Yas extrusions paub txhua leej txhua tus, vim hais tias lawv yog feem ntau siv nyob rau hauv lub neej. Lub ntsiab raw khoom yog cov cob, thiab feem ntau ntawm lawv muaj additives. Lawv yog cov ntaub ntawv uas ntws thiab tsim rau lub sijhawm ua haujlwm. Vim hais tias nws yog ib qho yooj yim siv, nws yog hlub los ntawm cov neeg.
Nws cov khoom tuaj yeem raug tso npe rau kev siv los yog kev ua haujlwm, kev faib cov tshuaj lom neeg, kev faib tawm ntawm crystallization, thiab kev sib tw ntawm kev tshav kub. Cov khoom yas yas moulding 2, kev sib tsoo molding 2, lamination molding 3, txias compression molding 4, hloov molding 5, tsis tshua muaj siab molding 6, extrusion molding 7, pultrusion 8, txhaj molding 9, tshuab molding 10. Casting 11, tes lay- tu 12, daim duab cua winding 13, calendering 14, txheej molding 15, hloov hloov molding 16, ua npuas ncauj molding 17, overmolding
Cov yam ntxwv yooj yim ntawm cov yas extrusions yog raws li nram no, qhov zoo yog lub teeb, thiab qhov zoo ntawm lub engineering qauv yog zoo heev txo. Kev siv cov extrusions yas tau zoo heev txo volumetric zoo thiab ua rau kom muaj kev sib ntaus los. Qhov txo qis ntawm cov khoom siv xws li tsheb yuav txo tau roj. Kev siv tshuaj tiv thaiv, tshuaj tiv thaiv, tiv thaiv tsis muaj corrosion thiab xeb (tsis muaj corrosion thiab corrosion xws li hlau cov khoom nyob rau hauv cheeb tsam atmospheric thiab mob kub thiab humid) hluav taws xob hluav taws xob zoo, zoo heev hnyav, kev sib txhuam txo thiab self-lubricating Cov yam ntxwv ntawm kev lag luam kev lag luam, zoo heev lub suab nrov, kev txo qeeb qeeb, kev cuam tshuam, kev qaug zog tuaj yeem ua kom lub chaw ua haujlwm zoo. Kev siv cov kev hloov kho tshuab tuaj yeem ua rau nws tus kheej muaj qhov tsis taus, uas yog qhov kev kawm zoo ntawm plastic plasticity.
