Thaum xaiv cov khoom siv plhaub, cov khoom muaj pes tsawg leeg yog thawj qhov ntev koj ntsib. Cov ntaub ntawv hlau tuaj yeem muab faib ua ntau hom, xws li txhuas alloys, stainless hlau, thiab carbon hlau. Aluminium alloys ua tiav lub teeb yuag thaum tswj lub zog ntawm cov qauv, thiab anodizing tsim cov txheej txheem ruaj khov. Stainless hlau ua tiav corrosion kuj los ntawm passivation zaj duab xis tsim los ntawm chromium, tab sis cov ntsiab lus carbon thiab alloy ntawm cov qib sib txawv cuam tshuam rau nws cov khoom siv kho tshuab. Engineering plastics suav nrog cov kev xaiv xws li polycarbonate thiab ABS resin. Polycarbonate muaj qhov zoo ntawm kev sib txuas ntawm lub teeb xa hluav taws xob thiab kev cuam tshuam, thaum ABS resin txhim kho qhov smoothness los ntawm nws cov ntsiab lus styrene. Cov ntaub ntawv sib xyaw feem ntau yog xa mus rau fiber ntau- cov qauv siv cov matrix ntxiv; Piv txwv li, kev sib txuas iav fiber ntau nrog cov resin matrix tuaj yeem ua rau tag nrho rigidity thaum tuav lub luj sib dua.
Thaum cov khoom raug txiav txim siab, cov txheej txheem tsim khoom ncaj qha cuam tshuam rau qhov kawg cov duab thiab kev ua haujlwm ntawm lub plhaub. Tuag casting yog tsim rau kev tsim cov txheej txheem nyuaj los ntawm cov ntaub ntawv hlau, txhaj tshuaj molten hlau rau hauv pwm nyob rau hauv siab, tab sis cov pwm precision txiav txim siab qhov ruaj khov ntawm cov khoom tiav qhov ntev. Txhaj tshuaj molding sib raug rau engineering yas ua; cov yas molten txias thiab solidifies nyob rau hauv lub pwm kab noj hniav, thiab lub rooj vag qhov chaw tsim muaj feem xyuam rau cov uniformity ntawm cov khoom ntws. Sheet hlau ua yog dabtsi yog khoov thiab stamping hlau los xij, thiab qhov dabtsi yog khoov vojvoog parameter yuav tsum tau raws li cov khoom siv ductility txwv. Cov txheej txheem kho deg muaj xws li cov txheej txheem sib txawv xws li txau thiab electroplating. Electrostatic txau siv lub hauv paus ntsiab lus ntawm kev them nqi adsorption kom ua tiav cov txheej txheem txheej txheej, thaum cov txheej txheem electroplating tso cov hlau txheej rau ntawm lub substrate los ntawm cov tshuaj tiv thaiv electrolytic.
