Thermal Expansion Stress a ni: Tropical sun hian car chunglam chu 70℃aia sangin a ti lum thei a, chu chu ruah nasa takin a sur nghal bawk. He thermal cycling hian fastener te a tizau thei a, a tichhe thei a niIP67/IP69K a nibattery enclosure-te sealing tih a ni.
EV Fasteners thlan dan tur ruahmanna pawimawh tak tak
A. Coating Technology hmasawn tak tak te
Standard zinc plating hi a tawk lo a ni1000+ darkar khat chhung chi (salt spray) a nitropical coastal region-a mamawh turte a ni.
- Dacromet leh Geomet hmanga siam a ni: Heng zinc-flake coatings te hian hydrogen embrittlement hlauhawmna awm lovin corrosion resistance tha zawk an pe a ni.
- Zinc-Nickel (Zn-Ni) hmanga siam a ni: EV underbody components tan standard a sang chho zel a, hei hi heat resistance sang tak leh sacrificial protection a nih vang a ni.
B. Material nena inmilna
Steel bolt leh aluminium battery housing inkara galvanic corrosion awm loh nan engineer-te chuan:
- Stainless Steel (304/316) hmanga siam a ni.: Pawn lam sensor leh charging port assembly atan a tha hle.
- Alloy Steel hmanga siam a ni a, Insulating Washers a awm bawk: Direct metal-to-metal contact tihziaawmna tur high-tensile structural joint tan a pawimawh hle.
C. Thil dik tak leh Tolerance
EV battery pack te hian hermetic seal an neih theih nan micron-level precision an mamawh a ni.AYA Fasteners hian tolerances ±0.05mm thlenga tight a tichiang a, vibration-heavy environment-a torque tension vawn rengna atan a pawimawh hle.
EV hman dan tur pawimawh tak tak
Battery Enclosure leh Powertrain te pawh a awm bawk
Battery tray securetu fastener te hian moisture lut tur an do thei tur a ni. Hman dan Hex Lu Self-Drilling Screw hmanga siam chhuah a niintegrated EPDM washers nen chuan secondary leak-proof barrier a pe thei a, chutih rualin high-speed assembly a awm thei bawk.
Chassis leh Suspension a awm bawk
EV battery rit lutuk hian chassis-ah stress sang zawk a siam a ni. High-tensile structural bolt (Grade 10.9 emaw 12.9) a ngai a, mahse an mechanical strength tichhe lo anti-corrosive coatings hmanga enkawl tur a ni.
Pawn lam thil (Mirror & Lighting) te .

Engvangin nge Dan zawm hi a pawimawh: IATF 16949
Brazil leh Thailand-a procurement manager-te tan chuan IATF16949 certification pek a nitih hi rinna signal hnuhnung ber a ni. Fastener-screw awlsam atanga custom bolt complex- thlenga khawvel pum huapa EV siamtute mamawh "Zero Defect" standard zawm turin quality inspection khauh tak an nei tih a tichiang a ni.
Tropical EV hmanna atana Technical Specifications te
Brazil leh Thailand-a EV-te tan chuan hun rei tak-rel theih nan a hnuaia technical threshold te hi rawt a ni.
1. Lei chunglam enkawl dan & Corrosion laka invenna (NSS Testing) .
Tropical coastal region-ah chuan Neutral Salt Spray (NSS) test hi industry benchmark a ni a, a chhe thei lo.

2. Hnathawh dan tehfung & zawm dan
International standard zawm hian fastener te chu khawvel pum huap EV platform (eg, Tesla, BYD, emaw Great Wall Motors standards)-ah awlsam taka inzawmkhawm theih a ni.
- Quality Management a ni: IATF 16949, IS09001 (Automotive quality enkawl dan tur ruahmanna siam a ni).
- Environment zawm dan tur: RoHS/IS014001 (EV-te "Green" image atan a pawimawh hle).
- Faina dan tur tehfung: ISO 16232 (Electronics leh battery pack sensitive tak takte tan a pawimawh hle).
