Core Fastening and Connection Solutions
Application of PCB（SMT）
Tin-plated copper nuts and standoffs are used for soldering onto PCBs to create threaded connections or for spacing; high-current terminals are designed for high-current applications to connect and provide conductivity to the PCB while forming reliable threaded joints, with internal and external threads available with pre-applied adhesive for anti-loosening; Ultra Screws are utilized for multi-layer PCBs and for connecting PCBs to sheet metal.
Riveting （Blind Riveting、Clinching）
**Self-clinching nuts/studs** and **rivet nuts/rivets** are used for server cabinet fastening; **self-clinching grounding terminals** are used for sheet metal earthing; **sealed clinching/riveting products** can achieve **IP68 waterproofing**; **flush-head rivets** meet **high flatness** requirements.
Thread Reinforcement for Light Alloys（Wire Thread Insert）
Carbon steel/stainless steel wire thread inserts are used for reinforcing threaded holes in light metal die-castings and profiles, such as aluminum and magnesium alloys. After reinforcement, the strength can reach Grade 8 or even Grade 12, significantly enhancing the connection reliability of light alloys.
Screws(Anti-loosening.Sealing.Captive Screw）
Bolts achieve anti-loosening through integrated assemblies (SEMS) and pre-applied adhesives. To reach an IP68 sealing rating, adhesives can be pre-applied under the head or on the threads, or specialized sealing rings can be integrated. Furthermore, captive screws remain attached to the panel after disassembly, specifically catering to the maintenance requirements of industrial electronic equipment panels.
Industry Challenges
Project Cycle Cost Influence Model
The early R&D decision window is extremely narrow yet locks in the majority of costs, while the cost of correction in later stages is prohibitively high. This creates a severe mismatch between risk and reward, necessitating precise, ultra-early judgment to navigate market uncertainties.
15-85 Law
Enterprises often over-focus on explicit procurement costs while overlooking the hidden costs that account for 85% of the total. A lack of systematic coordination across design, supply chain, and after-sales service inevitably inflates the Total Cost of Ownership (TCO) across the entire product lifecycle.
