Piav Qhia Txog MOQ thiab Lub Sijhawm Ua Ntej

Cov sijhawm tsim khoom ib txwm muaj thiab cov kev txwv tsawg kawg nkaus:

• Cov qauv kuaj: 7-10 hnub ua ntej xa khoom, tsis muaj MOQ

• Cov qauv kuaj tshwj xeeb uas xav tau cov cuab yeej tshiab / cov khoom siv tshiab: 15‑25 hnub

• Kev tsim khoom ntau ntau MOQ: 500‑1 000 pcs rau cov lus qhia tshwj xeeb; 2 000‑5 000 pcs rau kev txiav txim ntau tus qauv

• Lub sijhawm ua khoom loj: 15-20 hnub tom qab tau txais kev pom zoo ua qauv

• Kev pabcuam sai: muaj nrog rau 30‑50% ntxiv tus nqi.

Fullzen Technology cov zis txhua hli tshaj 50 000 lub nplhaib-hlau nplaum. Peb khaws cov khoom siv raw khoom kom txo qis kev hloov pauv ntawm lub sijhawm ua rau cov xaj tsis tu ncua.

Cov Txheej Txheem Pom Zoo Qauv - Tsis Txhob Dim Kauj Ruam Tseem Ceeb No

• Kev kuaj xyuas cov qauv yog koj lub rooj vag zoo tseem ceeb tshaj plaws ua ntej tsim ntau yam khoom:

• Tus neeg tsim khoom muab cov qauv ua ke nrog cov ntawv qhia kev xeem tag nrho (flux, qhov ntev, kev tshuaj xyuas txheej)

•Cov neeg siv khoom lees paub cov qauv raws li cov xwm txheej ua haujlwm tiag tiag

• Kos npe rau daim ntawv pov thawj qauv uas tau pom zoo

• Kev tsim khoom ntau yog ua raws li cov qauv ntsuas uas tau kos npe tawm.

Kev pheej hmoo ntawm kev hla dhau kev pom zoo rau cov qauv: nrhiav pom cov teeb meem demagnetisation, corrosion lossis haum-teeb meem tsuas yog tom qab pib tsim khoom ntau. Tus nqi ua haujlwm dua tuaj yeem yog 10-100 × tus nqi xaj qauv.

Cov Ntawv Pov Thawj Zoo: Lub Ntsiab Lus Ua Lag Luam

Cov ntawv pov thawj tsis yog tsuas yog cov khoom lag luam xwb - lawv tswj hwm ncaj qha rau cov khw twg koj cov khoom tiav tuaj yeem nkag mus rau:

• ISO 9001: daim ntawv pov thawj tswj hwm zoo uas txheeb xyuas cov txheej txheem tsim khoom raws li tus qauv

• IATF 16949: qhov yuav tsum tau ua kom zoo ntawm kev lag luam tsheb, yuav tsum muaj rau kev muab khoom siv hluav taws xob thiab khoom siv tsheb

• RoHS: ua raws li cov tshuaj txwv, yuav tsum muaj rau kev nkag mus rau hauv kev lag luam EU thiab North-American

• REACH: qhov yuav tsum tau sau npe tshuaj lom neeg rau kev xa khoom hauv EU

Fullzen Technology tuav daim ntawv pov thawj ISO 9001, thiab peb cov khoom dhau RoHS thiab REACH kev xeem ua raws li txoj cai. Rau cov neeg siv khoom tsheb, peb txhawb nqa IATF 16949-aligned workflows thiab PPAP Level 3 xa cov ntaub ntawv.

Cov Yuam Kev Xaiv Feem Ntau - Cov Lus Qhia Los Ntawm Lub Hoobkas Hauv Pem Teb

Tom qab ua tiav ntau txhiab qhov kev tsim khoom ntawm lub nplhaib-hlau nplaum, peb rov qab pom cov kev ua yuam kev ntawm cov nqi siab no thoob plaws hauv kev lag luam:

(1) Tsuas yog tsom mus rau qib hlau nplaum thaum tsis quav ntsej txog qhov sib txawv ntawm huab cua thiab kev tsim qauv hlau nplaum: lub rooj sib dhos N42 uas tau tsim zoo tuaj yeem ua tau zoo dua li cov khoom siv N52 uas tsim tsis zoo.

(2) Tsis quav ntsej txog qhov kub thiab txias ntawm kev ua haujlwm: kev siv tus qauv qib N42 hauv cov cav kub siab ua rau muaj kev tshem tawm tsis rov qab. Cov qib SH / UH-suffix yog qhov yuav tsum tau ua rau cov xwm txheej zoo li no.

(3) Kev xaiv txheej tsis raug: kev qhia Ni-Cu-Ni rau kev raug sab nraum zoov ua rau xeb hauv ob peb lub hlis; epoxy lossis Parylene yuav tsum tau xaiv hloov.

(4) Reversed magnetization polarity: uas tsis muaj N-S cim ntawm cov duab kos ua rau muaj kev hloov pauv polarity tag nrho thiab pov tseg.

(5) Saib tsis taus qhov cuam tshuam ntawm txheej txheej tuab: 0.5 hli cua-qhov sib txawv noj ib feem los ntawm plating tuab ua rau lub suab-kauj sib txawv thiab kev ua haujlwm tsis zoo.

(6) Kev tsis meej pem ntawm sintered vs bonded muaj peev xwm: qhia meej txog sintered NdFeB rau > 32-pole multi-pole qauv (txwv los ntawm kev txwv ntawm fixture); bonded NdFeB yog qhov kev daws teeb meem raug.

(7) Xa cov ntaub ntawv RFQ tsis tiav: cov lus thov "muab khoom siv hlau nplaum" tsis meej ua rau muaj ntau qhov kev ncua sij hawm piav qhia.

(8) Tsis txhob pom zoo ua qauv ua ntej muab kev txiav txim loj: kev tsim khoom loj tsis ua raws li cov nqi rov ua dua txog li 100 × tus nqi qauv.

(9) Tsis quav ntsej txog kev sib xws ntawm pawg mus rau pawg: thawj pawg ua tau zoo thaum pawg thib ob hloov pauv; ib txwm xav tau cov ntaub ntawv tshuaj xyuas hla pawg.

(10) Sim ua haujlwm thib ob hauv tsev rau cov hlau nplaum: kev khawb lossis txiav cov hlau nplaum tsim kom muaj qhov kub siab hauv zos, ua rau muaj kev puas tsuaj ib nrab ntawm cov hlau nplaum thiab kev puas tsuaj rau txheej.
