We support 5 standardized and fully customizable production workflows, each optimized for specific application scenarios, volume requirements and product designs. Every process is fully automated with integrated real-time inspection to ensure zero-defect output.
Ideal for high-volume standard integrated tapping assemblies. Our in-mold tapping technology ensures consistent thread precision across every piece, while end-to-end automated inspection guarantees zero defective products, reducing your in-house quality control costs and rework risks.
Designed for compact electrical contact assemblies, this process is perfectly suited for household switch and thermostat applications. It delivers stable welding performance, high production efficiency and excellent electrical conductivity, with tight dimensional tolerances to match compact product designs.
Optimized for high-load electrical applications requiring superior arc resistance and long service life. The tri-metal composite strip delivers consistent electrical performance across extreme temperature and voltage fluctuations, making it ideal for circuit breakers and industrial relay components.
This process supports single or double wires (round or square wires) with diverse riveting methods, including single-side or double-side riveting, specifically designed for single-metal contact applications. It offers flexible design options for custom contact configurations, with full automation to ensure consistent riveting strength.
Available with single or double contact riveting methods, engineered specifically for composite metal contact applications. This process delivers excellent bonding strength between the contact and base material, with fiber optic sensor detection to eliminate missing rivets, ensuring 100% component integrity for high-reliability applications.
Our integrated tapping assemblies adopt fully automated in-mold riveting and in-mold tapping technology, integrated with fiber optic sensor detection for missing rivets. This completely eliminates manual riveting processes, significantly cuts your labor and management costs, and avoids human-induced defects that cause batch rework and after-sales issues.
Compared with traditional manual riveting, our automated in-mold process delivers tighter dimensional tolerances, consistent thread quality and stable electrical performance across every production batch. Full-process optical inspection ensures an ultra-low defective rate, reducing your in-house QC workload and minimizing product failure risks in end applications.
We maintain a maximum monthly production capacity of 60 million pieces, with flexible production scheduling to meet your bulk orders, seasonal peak demand and long-term stable supply requirements. We support both prototype small-batch and mass production runs, with no strict minimum order quantity for custom development projects.
Our integrated one-stop production process greatly shortens the production cycle compared with split manual workflows. We provide fast lead times for both standard and custom products, helping you shorten your product launch cycle and respond to market demand quickly, without compromising on quality.
