Cov txheej txheem tsim cov ntawv zinc alloy encompasses tuag casting, kho deg (xws li electroplating), thiab precision machining (xws li laser engraving). Los ntawm kev sib koom tes ntawm ntau cov txheej txheem, siab -precision, ruaj, thiab zoo nkauj hlau cim tau tiav.
1.Die Casting: Cov tub ntxhais ntawm siab -Precision Moulding
Lub cev tseem ceeb ntawm zinc alloy daim ntawv lo yog tsim los siv lub siab -siab tuag casting txheej txheem. Molten zinc alloy (qib ntau xws li YZZnAl4A) yog txhaj rau hauv cov pwm kab noj hniav ntawm kev kub ceev thiab siab. Tom qab txias sai, ib qho khoob nrog cov duab nyuaj thiab cov phab ntsa tuab tuab tau txais. Cov txheej txheem no txhawb nqa qhov tsawg kawg nkaus phab ntsa tuab ntawm 0.3mm thiab tuaj yeem ua kom raug cov ntsiab lus xws li logos, ntawv, thiab embossed textures.
Cov Ntsiab Lus Pwm Tsim Cov Ntsiab Lus: Ua kom zoo rau qhov sib cais ntawm qhov chaw thiab lub qhov rooj kom tsis txhob flash thiab porosity; siv cov sliders los yog cov tub ntxhais- rub cov txheej txheem rau cov qauv nrog undercuts kom ntseeg tau tias du molding.
Parameter Control Points: Kev txhaj tshuaj kub yuav tsum tswj ntawm 430-450 degree; tuav lub siab thiab lub sij hawm yuav tsum tau sib phim rau qhov thickness kom tsis txhob shrinkage kab noj hniav thiab deformation.
Tshaj tawm - ua tiav thiab pib ua tiav: Tshem tawm cov rooj vag thiab burrs feem ntau ua los ntawm kev sib tsoo vibratory (ceramic hlaws, 1-3 mm) lossis ultrasonic tu. Kev tuav tiav siv cov ntaub ntawv pob zeb diamond los kho cov khoom seem hauv zos.
2.Surface Treatment: Enhancing Corrosion Resistance and Decorative Appearance Die-cov ntawv cam khwb cia yuav tsum tau ntau-theem deg kev kho mob los txhim kho kev tiv thaiv kev ua tau zoo thiab ua tau raws li qhov yuav tsum tau pom, nrog electroplating yog ib qho ntawm cov txheej txheem tseem ceeb.
Ua ntej- txheej txheem kho: Qhov no suav nrog ultrasonic dewaxing → dej kub ntxuav → tshuaj degreasing → cathodic electrolytic degreasing → ua kom → pre-immersion, kom ntseeg tau tias lub substrate yog huv si thiab tsis muaj roj, muab zoo adhesion rau tom ntej plating txheej.
Electroplating txheej txheem xaiv:
Decorative Plating: A common combination is "pre-plating copper (5–10μm) → bright nickel plating → chromium plating (>0.25μm)," tsim ntau- txheej tooj liab / npib tsib xee / chromium qauv uas sib xyaw ua ke siab gloss thiab corrosion kuj.
Environmental Trends: Cyanide- cov txheej txheem dawb electroplating (xws li pyrophosphate systems) yog maj mam hloov cov tshuaj cyanide plating, ua raws li RoHS cov lus qhia thiab tsim nyog rau cov khoom xa tawm.
Lwm yam kev kho mob saum npoo: PVD txheej (xws li kub, sawv kub), oxidation xim lossis txau kuj tuaj yeem ua kom tau txais cov txiaj ntsig tshwj xeeb xws li antique bronze thiab matte dub.
