1.New Energy Vehicles: Primary Growth Driver of Cold Heading Industry
A conventional fuel-powered passenger car needs roughly 2,000~3,000 fasteners, while new energy vehicles (NEVs) require 35% more cold-headed fasteners per vehicle thanks to widespread adoption of battery packs, electric drive assemblies and lightweight chassis structures. Fast-growing demands cover battery flange bolts, high-voltage connecting studs, motor shaft pins and Grade 10.9/12.9 high-strength chassis studs. As a result, 6-die & 7-die high-speed servo multi-station cold heading machines have become the mainstream replacement equipment for fastener manufacturers, with procurement volume of NEV-specified cold heading equipment surging 31% year-on-year in Q1 2026.
Driven by vehicle lightweighting, aluminum and bimetallic composite fasteners gain growing market share, pushing equipment suppliers to optimize die design and upgrade servo feeding systems for one-step near-net forming of irregular composite components. Outdated mechanical low-speed heading machines and old 2-die-4-blow units are phased out gradually; leading domestic fastener enterprises purchase full-servo multi-station machines in bulk to expand fixed-point production capacity for mainstream NEV OEMs.
2.Technological Upgrade Trend of New-generation Cold Heading Machines (2026 Standard Configuration)
All newly-launched 2026 cold heading models adopt three core configurations: full servo direct-drive system, digital twin real-time monitoring and modular machine frame structure.
- Energy Saving: New models cut comprehensive power consumption by over 30% vs traditional cam-driven machines, fully complying with energy-saving subsidy policies for green intelligent factories.
- Production Efficiency: Max working stroke hits 240 strokes per minute; stable continuous production of 6+ die machines ranges from 180 to 220 strokes/min.
- Machining Precision: Repetitive positioning accuracy reaches ±0.002mm to meet strict dimensional tolerance of precision parts for EV and robotic industries.
- Intelligent Control: Equipped with EtherCAT fieldbus closed-loop control system to collect real-time data of forming load, die temperature and feeding deviation; integrated digital twin enables remote equipment maintenance, automatic fault diagnosis and full production traceability, supporting unattended continuous workshop production.
High-end domestic cold heading equipment speeds up import substitution against European, American and Japanese counterparts, especially in NEV and precision micro-component manufacturing segments.
