Engineered Fastening Solutions for Aerospace and Automotive Manufacturing
In high-vibration and safety-critical environments like commercial aerospace and Electric Vehicle (EV) manufacturing, fastener selection goes beyond basic shear strength. At Jiliang Fastener Manufacturing, we specialize in producing OEM solid and semi-tubular rivets that meet strict weight reduction, cyclic fatigue, and galvanic corrosion standards for top-tier automotive and aviation assembly lines.
Rather than offering off-the-shelf catalog items, we engineer custom fastening solutions to overcome complex joining challenges, ensuring structural integrity in applications where failure is not an option.
Aerospace Rivet Solutions: Maximizing Strength-to-Weight Ratios
Aircraft fuselage, wing skin, and internal bulkhead assemblies demand permanent, fail-safe joints that can withstand extreme aerodynamic loads, rapid temperature fluctuations, and pressure cycling.
- Precision Solid Rivets for Primary Structures: We manufacture high-precision solid rivets designed for maximum shear load transfer. Our precision cold-heading process ensures a flawless shank that completely fills the drilled hole during the bucking process, virtually eliminating microscopic crack propagation and metal fatigue.
- Aviation-Grade Material Matrix: We don’t just use standard aluminum. We process specific aerospace grades according to customer specifications, including 2117-T4 (AD rivets) for general structures, 2017-T4 (D rivets) for high-shear applications, and 7050-T73 alloys for ultimate strength-to-weight performance. We also manufacture from high-tensile titanium and 316L stainless steel for engine-proximity applications.
- Aerodynamic Flush Seating: For exterior skin assemblies, we offer exact 100-degree and 120-degree countersunk head configurations to eliminate aerodynamic drag and maintain a perfectly smooth fuselage profile.
Automotive & EV Fasteners: Lightweighting & Crash Safety
The modern automotive industry, particularly the rapidly expanding Electric Vehicle (EV) sector, is aggressively pursuing lightweighting to extend battery range without compromising structural rigidity or passenger crash safety.
- Semi-Tubular Rivets for Mixed-Material Joining: Traditional spot welding struggles or fails when joining dissimilar materials, such as bonding an aluminum chassis frame to composite body panels or carbon fiber components. Our custom semi-tubular rivets require exceptionally low setting force, creating a secure, permanent clinch without fracturing brittle plastics or composites.
- EV Battery Enclosure Protection: Fasteners used in EV battery packs must withstand constant road vibration, thermal expansion, and harsh exposure to environmental elements. We engineer battery enclosure rivets that provide high resistance to electrolyte corrosion and prevent moisture ingress, maintaining the gas-tight integrity of the battery housing.
- Automated Assembly Integration: In high-volume automotive production, cycle time is profit. Our semi-tubular designs are manufactured with exact dimensional consistency, perfectly concentric holes, and chamfered ends. This makes them perfectly suited for high-speed automated track feeds and robotic riveting cells, drastically reducing jamming and assembly downtime.
Advanced Surface Treatments: Combating Galvanic Corrosion
When dissimilar metals are joined (e.g., aluminum rivets in steel panels), galvanic corrosion is a severe threat. Jiliang provides industry-leading surface coatings to ensure long-term joint survivability:
- Zinc-Nickel Alloy Plating: Offering up to 1,000 hours of Salt Spray Test (SST) resistance, ideal for under-body automotive applications.
- Dacromet & Geomet Coatings: Providing superior hydrogen embrittlement relief and exceptional heat resistance.
- Aerospace Anodizing: Enhancing the natural oxide layer of aluminum rivets for superior weatherability and paint adhesion.
Zero-Defect Quality Assurance & PPAP Compliance
As a source factory with over 15 years of OEM experience, our manufacturing floor is built for precision. We understand the rigorous documentation required by Tier-1 and Tier-2 manufacturers.
- Strict Tolerance Control: Our multi-station cold heading machinery maintains shank diameter and head concentricity tolerances to within ±0.01mm.
- Optical Sorting: We utilize automated optical inspection (AOI) lines to guarantee zero mixing and 100% dimensional compliance before packaging.
- Comprehensive Documentation: We provide full material traceability, Mill Test Reports (MTR), and Production Part Approval Process (PPAP) Level 3 documentation upon request.
Whether you are scaling up EV production lines or sourcing precision hardware for aerospace maintenance, Jiliang delivers OEM fasteners on time and to exact specifications.
