Surface Protection & Corrosion Resistance

Vim tias cov hlau nplaum neodymium muaj cov feem pua ntawm cov hlau, cov khoom tsis muaj kev tiv thaiv oxidizes sai heev hauv huab cua. Peb siv cov txheej txheem tshwj xeeb plating kom phim qhov chaw ua haujlwm nruj:

Nickel-Copper-Nickel (Ni-Cu-Ni):

Txheem peb- txheej plating (15 ~ 25 um tag nrho cov tuab). Muab qhov ua tiav du thiab ruaj khov rau sab hauv tsev atmospheric corrosion.

Epoxy txheej:

Siv los ntawm electrophoretic deposition. Muab cov dej kom zoo thiab ntsev-Txoj kev tiv thaiv rau cov av noo lossis sab nraum zoov.

Zinc Plating:

Tus nqi - muaj txiaj ntsig kev lag luam tiav rau cov txheej txheem kaw.

Quality Control & Batch Inspection Protocol

Txhawm rau kom muaj kev sib raug zoo thoob plaws kev tsim khoom lag luam thiab ua tau raws li kev cai nruj thoob ntiaj teb OEM cov cai, txhua pawg tsim khoom tau raug kuaj xyuas nruj:

Raw Material Verification:

Kev ntsuas tshuaj muaj pes tsawg leeg thiab kev sib koom ua ke ntawm spectrometer thiab BH hysteresis graph tracers.

Dimensional & Tolerance Checks:

Txheeb xyuas siv cov calipers, micrometers, thiab optical piv rau cov neeg siv khoom CAD kos duab.

Magnetic Flux & Pull Force Testing:

Ntsuas nrog Helmholtz coils thiab rub- cov neeg ntsuas kom ntseeg tau tias qhov sib txawv nyob hauv +/- 3% ntawm cov phiaj xwm tshwj xeeb.

Txheej Adhesion & Kev ncaj ncees:

Hla -hatch daim kab xev kuaj thiab tshuaj ntsev tsuag corrosion (48 ~ 96 teev nyob ntawm plating spec).

Ntim thiab Export Logistics

NdFeB hlau nplaum tsim cov hlau nplaum muaj zog uas tuaj yeem cuam tshuam nrog cov khoom siv thauj khoom yooj yim lossis ua rau huab cua freight cov cai.

Tiv thaiv:

Inner packaging utilizes high-density iron sheet shielding or spaced air-gap positioning to contain the magnetic flux within permitted transport thresholds.

Cushioning:

Cov blocks ntawm tus kheej yog sib cais los ntawm cov tsis yog- sib nqus ua npuas ncauj spacers thiab ntim rau hauv cov khoom siv ntxiv ob npaug - cov thawv corrugated nrog cov ntaub qhwv tsis muaj dej.

Lub Sijhawm Ua Haujlwm & MOQ:

Txheem ntau lawm thiab sampling khiav ntawm 2 ~ 3 lub lis piam coj mus kuaj. Yam tsawg kawg nkaus Order Quantity (MOQ) yog soj ntsuam yooj yim raws li kev cai qhov ntev thiab cov khoom qib.
