Unlocking NEV Lightweight Safety Connections

[Abstract]:As an innovation leader in the fastener industry, Yingjing Precision specializes in lightweight connection solutions for new energy vehicles.

As the new energy vehicle (NEV) industry shifts from volume expansion to market competition in 2026, OEMs face the critical challenge of balancing lightweight design, safety, and total lifecycle costs. As an innovation leader in fasteners, Yingjing Precision (parent company: Yingfeng Zhichengjia) recognizes that every micro-connection is the cornerstone of vehicle performance and safety.

Leveraging over 20 years of precision manufacturing expertise and NEV-specific solutions, we serve as your "Total Cost Optimization Expert" from design to aftermarket, utilizing innovative connection technologies to help you break through in a competitive market.

Redefining Fastener Value
In early automotive R&D, the "15-85" cost paradox prevails: 15% visible procurement costs hide 85% in design, assembly, aftermarket, and quality risks. Our mission is to transform this 85% uncertainty into tangible benefits through forward-looking material connection solutions.

We provide more than fasteners; we deliver "One-Stop Connection Solutions." Backed by robust production capacity at our Shenzhen headquarters and Xiangyang automotive-dedicated factory, along with IATF16949 certification, we offer comprehensive technical support for powertrains, body structures, and chassis.

Overcoming Lightweight Material Challenges
The widespread use of aluminum and magnesium alloys introduces challenges like low thread strength and galvanic corrosion. We offer a dual approach:

High-Strength Threaded Inserts: Carbon steel and stainless steel inserts, embedded via cold heading or injection molding, elevate fragile thread strength to Grade 8 or Grade 12+, ensuring rock-solid stability under high torque.
High-Strength Aluminum Bolts: Designed for magnesium die castings, these bolts precisely control the potential difference. Combined with physical isolation coatings on bolt heads, they eliminate galvanic corrosion risks at the source.

IP68 Sealing & Locking for Powertrains
Meeting strict IP68 waterproofing standards, we integrate sealing and locking directly into our fasteners:

Integrated Sealing: High-performance sealants pre-applied to blind rivet nuts and motor bolts create a watertight barrier, protecting cells and circuits in harsh environments.
Advanced Locking: From mechanical double-nut designs to chemical pre-applied thread-locking patches, our patented combinations ensure connections remain secure on rough terrains.

Efficiency Revolution via Cold Heading
Replacing traditional CNC machining with direct cold heading for sleeve structural parts and standard components drastically improves material utilization and production cycles. Through process optimization and simulation analysis, we have helped clients reduce unit costs by over 20%, making manufacturing simpler and costs highly controllable.

Full Lifecycle Technical Support
We create value at the R&D source:

Rapid Prototyping: Leveraging in-house full-process capabilities, we deliver engineering samples in as fast as 1 day.
Design Consulting: Our team provides 2D/3D drawing support and simulation analysis. Optimizing parameters (e.g., replacing sharp corners with fillets) improves yield rates and saves significant mold development costs.

Amidst the 2026 automotive industry transformation, Yingjing Precision remains committed to becoming an innovation leader in precision fasteners. Driven by Shenzhen's innovation hub and Xiangyang's automotive manufacturing base, we empower the high-quality development of the global NEV industry with ultimate connection technologies.
