Ndi zinthu ziti zomwe zimakhudza kwambiri electroplating khalidwe la zinc alloy die castings?

Kuti zinki alloy kufa castings kukhala electroplated pamwamba mankhwala, ulalo ndi zofunika kwambiri. Ngati electroplating sichinachitike bwino, ntchito yonse yoyambira idzawonongeka. Choncho, tiyenera kulabadira njira electroplating mankhwala. Ndiye ubwino wa electroplating umakhudzidwa ndi zinthu zimenezo. Huayin Die Casting akufotokozerani mwachidule zotsatirazi:

1. Posankha zida zopangira zinc alloy die-casting parts, zinthu zokhazikika zapadziko lonse lapansi ziyenera kusankhidwa kuti zitha kuponyedwa.

 2. Mapangidwe a zinc alloy die-casting parts ayenera kukhala omveka. Maonekedwe a magawo oponyera kufa ayenera kuganizira kubisala kwa electroplating, ndikuyesera kuchepetsa mabowo osadutsa, kotero kuti sizovuta kunyamula njira mukutsuka madzi. Dulani ngodya zakuthwa ndi mbali zina kuti mizere yamagetsi igawidwe mofanana pa electroplating.

  3. Njira yopangira ufa ndi mapangidwe a nkhungu yofa ndi yololera, kotero kuti ziwalo zakufa sizidzavutika ndi zofooka za shrinkage, pinhole ndi looseness. Zolakwika zomwe tatchulazi zidzakhudza mwachindunji kumamatira kwa zokutira.

 4. Popanga kupanga zinki aloyi kufa castings, yesetsani kuchepetsa tsankho chodabwitsa. Ngati aluminiyamu imalekanitsa mbali zina, aluminiyumu amayamba kusungunuka panthawi ya degreasing, zomwe zingayambitse pores ndi pinholes pamwamba pa kufa-kuponyedwa ndipo sangathe kutsukidwa, zomwe zimapangitsa kuti zisamangidwe bwino, zomwe zimapangitsa kuti kupaka ndi kuphulika.

 5. Samalani ndi sikelo panthawi yopera ndi kupukuta. Mtundu wabwino wa 0.05~0.1mm kupangidwa pa ndondomeko yozizira ya kufa kuponyera n'kofunika kwambiri kwa electroplating. Kutayika kwa wosanjikiza wabwino kuyenera kuchepetsedwa momwe mungathere pakupera ndi kupukuta. Ngati wosanjikiza uwu watsitsidwa ndikutayidwa, Zomwe zidzawululidwe ndi mawonekedwe a porous, ndipo palibe wosanjikiza wabwino wa electroplating womwe ungapezeke pagawo ili.

  6. Mkuwa-nickel-chromium electroplating wosanjikiza wopangidwa ndi mitundu ingapo ya plating ndi wosanjikiza woipa wokhudzana ndi gawo lapansi. Malingana ngati kukonza kwamakina kumakhala kothandiza, zinki alloy zigawo zimawononga mumlengalenga wonyowa, kotero ndikofunikira kuwonetsetsa kuti plating wosanjikiza ndi dzenje laulere. Kupanda kutero, dzimbiri za aloyi ya zinc zingayambitse matuza a zokutira. Poyerekeza ndi zigawo zachitsulo, plating wosanjikiza uyenera kukhala wokulirapo kuti ukhale woyenera zinc alloy die castings.

7. Zotsalira za ziwalo zoponyera kufa panthawi yoponyera ndi makina ziyenera kutsukidwa momwe zingathere pambuyo pokonza. Chifukwa chotsaliracho ndi chitsulo chowoneka bwino, munjira iliyonse ya electroplating, imachitapo kanthu ndi yankho ndikuwononga yankho la plating, lomwe lidzakhudza ubwino wa plating.
