| OEM Overview: | We support ODM (Original Design Manufacturer) services, capable of customizing products according to clients' specific requirements and providing comprehensive technical support throughout the process. Whether it's adjusting product specifications, optimizing functional modules, or solving technical challenges in production, our professional team will collaborate closely with clients—from the initial demand analysis to final product implementation—to ensure that the customized solutions perfectly match actual application scenarios. Additionally, we offer long-term technical follow-up services, including parameter debugging, system upgrades, and after-sales maintenance, to help clients reduce development costs and shorten market entry cycles, thereby enhancing product competitiveness in the target market.
|
| Production Line: | 1. ODM for Diverse Parameter Customization
Tailored to specific technical parameters (e.g., detection range, response time, or environmental adaptability), our ODM service starts with a comprehensive requirement analysis. Our engineers collaborate to fine-tune hardware configurations—such as upgrading sensor modules for 0.1ppm-level SF6 detection—and optimize software algorithms to meet unique operational scenarios. Each customization undergoes 3-stage validation (simulation, prototype, field test) to ensure parameter consistency with industry standards.
2. ODEM for Project-Centric Solutions
Addressing end-to-end project needs, we integrate customer-specific functionalities (e.g., IoT connectivity or explosion-proof designs) into the development roadmap. This includes:
Requirement mapping: Translating project briefs into technical blueprints with 3D modeling Cross-functional collaboration: Coordinating R&D, production, and QA teams for concurrent engineering Milestone verification: Conducting FAT (Factory Acceptance Test) with clients to ensure alignment with project timelines 3. Precision Assembly & Technical Debugging
Our ISO-certified workshop executes:
Class 1000 cleanroom assembly for sensor modules to prevent contamination Multi-point calibration using NIST-traceable standards (accuracy ±0.5%) 48-hour continuous operation testing under extreme conditions (-40°C to 70°C)Post-debugging, each device is paired with a digital twin for real-time performance monitoring, ensuring compliance with technical specifications like IEC 62271 or GB/T 18850. 4. Secure Packaging & Global Logistics
Triple-layer protection: Anti-static bag + shock-absorbing foam + corrugated outer carton Climate-controlled shipping: Options for temperature-sensitive equipment (2-8°C monitoring) End-to-end tracking: Automated notifications via IoT logistics tags, with customs clearance support for international ordersEach package includes a damage-inspection QR code linked to our 24/7 support hotline, minimizing transit risks and ensuring 100% delivery integrity. |
| R&D: | A 20-person technical R&D team, comprising senior engineers with 8+ years of experience, drives product iteration and technology exploration. Operating across hardware, software, and testing groups, the team allocates 30% of resources to upgrading existing products—like improving SF6 analyzer accuracy by 15%—and 70% to new projects such as next-gen fluorine gas sensors and AI analysis systems.
Based in a 500㎡ lab with GC-MS equipment, the team collaborates with three universities, holding 12 national patents including a trace gas adsorption technology that achieves 0.1ppm detection limits. Their R&D focuses on industry trends like low-power IoT monitors and cloud-based gas management, with modular designs and cross-platform software ensuring international-standard innovations. |
