Ndezvipi zvinhu zvinokanganisa yakanakisa electroplating mhando yeZinc alloy die castings？

Kuti zinc alloy die castings ive electroplated pamusoro kurapwa, iyi link yakakosha. Kana iyo electroplating isina kuitwa zvakanaka, basa rose mukutanga danho richaparara. Naizvozvo, isu tinofanira kuterera kune electroplating maitiro echigadzirwa. Zvadaro kunaka kwe electroplating kunokanganiswa nezvinhu izvozvo. Huayin Die Casting inopfupisa zvinotevera kwauri:

1. Pakusarudzwa kwezvinhu zvakasvibirira zvezinc alloy die-casting parts, zvenguva dzose zvemhando yenyika zvinofanirwa kusarudzwa kune chigadzirwa kufa-casting.

 2. Dhizaini yezinc alloy die-casting parts inofanira kuva inonzwisisika. Chimiro chezvikamu zvekufa-kandira chinofanira kufunga nezvekuvanza kukwanisa kwe electroplating, uye edza kuderedza kusina-kuburikidza nemakomba, kuitira kuti zvive nyore kutakura mhinduro mukushambidza mvura. Cheka makona akapinza uye zvimwe zvikamu kuti mitsara yemagetsi igovane panguva ye electroplating.

  3. Kufa-kukanda maitiro uye kufa-casting mold design inonzwisisika, kuitira kuti zvikamu zvekufa zvirege kutambura nekukanganisa kwe shrinkage, pinhole uye looseness. Izvo zvikanganiso zvataurwa pamusoro apa zvichakanganisa zvakananga kunamatira kwekuputira.

 4. Mukugadzirwa kwe zinc alloy die castings, edza kuderedza chiitiko chekuparadzanisa. Kana aruminiyamu yakapatsanura mune zvimwe zvikamu, aruminiyamu inozotanga kunyungudika panguva yekudonha, izvo zvinokonzeresa pores nemapinipa pamusoro pekufa-kukanda uye hazvigone kucheneswa, zvichikonzera kusasimba kwekubatana, zvichikonzera kusvuura uye kuputika kwekuputira.

 5. Teerera kuchiyero panguva yekukuya nekupukuta. Iyo yakanaka layer ye0.05~0.1mm yakaumbwa panguva yekutonhora kwekukanda kufa yakakosha kune electroplating. Kurasikirwa kwechigadzirwa chakanaka kunofanira kuderedzwa zvakanyanya sezvinobvira panguva yekukuya uye kupurisa. Kana iyi layer ivhu uye yakaraswa, Chii chicharatidzwa chimiro cheporous, uye hapana yakanaka electroplating layer ichawanikwa pane iyi layer.

  6. Mhangura-nickel-chromium electroplating layer inoumbwa nemhando dzakasiyana-siyana dzekuputira ndeye negative plating layer maererano ne substrate. Chero bedzi iyo mechanic gadziriso ichishanda, zinc alloy zvikamu zvinopera mumhepo ine hunyoro, saka zvinodikanwa kuve nechokwadi chekuti plating layer igomba remahara. Zvikasadaro, zvigadzirwa zvekuora zve zinc alloy zvinokonzeresa kuputika kwejasi. Kuenzaniswa nezvikamu zvesimbi, iyo plating layer inofanirwa kuve yakakora kuti ikwane zinc alloy die castings.

7. Zvisaririra zvezvikamu zvekufa-kandira panguva yekufa-kukanda uye machining zvinofanira kucheneswa zvakanyanya sezvinobvira mushure mekugadzirisa. Nekuti iyo yakasara isimbi yakajeka, mune chero maitiro e electroplating, ichaita nemhinduro uye kukuvadza mhinduro yeplating, iyo inokanganisa kunaka kweiyo plating.
