Covers core components of traditional fuel vehicles and new energy vehicles, including precision screws for engine blocks and transmission housings, connecting parts for chassis suspensions and steering systems, fixing bolts for new energy vehicle battery packs (including module fixing and case sealing), as well as fixing screws for electronic components such as sensors and ECUs (Electronic Control Units).

Such fasteners must adapt to severe working conditions including high-frequency vibration, high-low temperature cycles, humidity and corrosion, while meeting the efficiency requirements of mass production.

• High-Strength Performance Control: Core fasteners require excellent tensile strength, torsional strength and fatigue resistance to withstand high-frequency vibration and alternating loads during vehicle operation.
• Consistency Assurance for Mass Production: Automated production lines including automatic feeding, CNC machining, automatic inspection and automatic packaging ensure dimensional consistency across batches.
• Customized and Lightweight Production: Customized products with non-standard threads, flange faces and anti-loosening structures. Lightweight materials such as aluminum alloy and titanium alloy support extended cruising range for new energy vehicles.
• Special Requirements for New Energy Vehicles: Battery pack fasteners must bear weight, vibration and temperature changes with torque requirements exceeding 200 N*m, plus good insulation and corrosion resistance.

• Ultra-high precision: Standard tolerance ±0.01 mm, precision version up to ±0.001 mm
• Strong consistency: Program-controlled, highly uniform dimensions in batches
• Flexible customization: No mold required, fast switching for non-standard specifications
• Wide material compatibility: Capable of machining stainless steel, titanium alloy, aluminum alloy, copper alloy, high-temperature alloy, etc.
• Flexible efficiency & batch size: Suitable for small-batch prototyping and medium-batch customization
