Core Fastening and Connection Solutions
Composite Material Bonding
High-strength bonding solutions allow for the structural integration of composite materials without the need for drilling, thereby preserving their non-destructive integrity.
Riveting - Press-fit, Blind Riveting (Sealed & Non-sealed)）
Self-clinching nuts/studs, blind rivet nuts, and blind rivets are used for fastening and securing HPC-AI server sheet metal enclosures, while self-clinching grounding terminals are utilized for sheet metal grounding connections.
Anti-loosening Washers
Double-layered wedge-locking washers are designed for scenarios with high transverse vibration loads, utilizing the lead angle principle to achieve a reliable anti-loosening effect. Meanwhile, single-sided serrated conical washers are adapted for alternating vibration loads, providing clearance compensation and enhanced frictional resistance.
Screws - anti-loosening, sealing, captive screw and others
Bolts achieve anti-loosening through specialized assemblies or by pre-coating threads with chemical or physical locking agents. To meet IP68 sealing standards, bolts can also be pre-coated under the head or on the threads, or integrated with sealing rings. Furthermore, captive screws ensure that the fasteners remain attached to the panel even after disassembly, preventing hardware loss.
Industry Challenges
Project Cycle Cost Influence Model
R&D in the Low-Altitude Economy faces a major hurdle: early decisions lock in costs while late-stage corrections are vastly expensive, causing a profound mismatch between risk exposure and potential returns.
15-85 Law
Enterprises often over-focus on explicit procurement costs, overlooking the hidden costs that account for 85% of the total. A lack of systematic coordination across design, supply chain, and after-sales results in high manufacturing costs, frequent rework, and heavy service burdens—ultimately driving up the Total Cost of Ownership (TCO).
