Description

Round brass nuts, custom engraved patterns for through nuts, CNC precision machining of nuts

New Energy Vehicles: Electronic Control & Battery Pack

Practical Products

Lock nuts for battery pack housings, motor fixing nuts, electronic control box cover nuts, wiring harness bracket fastening nuts, and water cooling plate sealing nuts.

CNC Production & Processing Features

Most products adopt non-standard thin, special-shaped, or short cylindrical structures. CNC enables integrated machining of foolproof positioning grooves, sealing surfaces, insulation sections, and knurled anti-slip profiles.
Supports various materials including aluminum alloy, stainless steel, and copper alloy, meeting the lightweight requirements of new energy vehicles.
Surface treatments include anodizing (for aluminum) and passivation (for stainless steel) to enhance insulation and corrosion resistance. Internal threads are precisely manufactured for miniature bolts with strict tolerance control.
Small in size and space-saving, they support compact layouts of battery packs and electronic control boxes, helping to extend the driving range of new energy vehicles.
Excellent waterproof and dustproof sealing meets the battery pack protection requirement of IP67 or higher.
Smooth and efficient assembly with bolts; no corrosion, overheating, or loosening during long-term operation, avoiding battery short circuits and motor damage caused by nut failure, ensuring stable performance of the NEV electronic control system.

Common CNC Machining Issues & Key Points

  • Aluminum Alloy Machining:
    Soft aluminum material tends to cause tap adhesion, rough threads, and surface scratches during internal threading. Special aluminum taps shall be used, with increased cutting fluid supply and controlled cutting speed to prevent adhesion and burrs, ensuring smooth internal threads.
  • Sealing Surface Machining:
    Nuts for water cooling plates and battery pack sealing surfaces require flawless smooth sealing surfaces to prevent liquid leakage. Fine milling of sealing surfaces is necessary, with surface roughness controlled to Ra ≤ 1.6 μm for tight fitting with seals.
  • Foolproof Structure Machining:
    Dimensional deviations in foolproof positioning grooves may cause assembly jamming. Positioning grooves must be strictly machined per drawings to ensure precise matching with mating parts, avoiding assembly errors and improving efficiency.
  • Insulation Section Machining:

    Insulation sections of electronic control nuts require uniform dimensions; uneven wall thickness will reduce insulation performance. Turning precision must be controlled, insulation layer thickness and integrity inspected, and damage to the insulation layer during internal threading avoided.
