Our Seamless OEM/ODM Partnership Process
From your initial concept to deep-sea deployment, HYSF ensures precision, quality, and speed at every stage.
We begin by understanding your specific mission requirements—depth, environment, core count, and material preferences. Our engineers conduct a feasibility study to ensure the optimal interconnect solution for your ROV, AUV, or sensor system.
Step 01: Consultation & Feasibility
30%
Using advanced CAD and simulation tools, we create detailed technical drawings. We offer customization of housing materials (316L/Titanium), pin configurations, and specialized L-shaped or low-profile mechanical footprints.
Step 02: Engineering & Design
40%
Once the design is approved, we produce a functional prototype. This stage includes initial electrical testing and material verification to ensure the design meets your integration standards before mass production.
Step 03: Prototyping & Verification
45%
Reliability is non-negotiable. Every custom design undergoes hydrostatic pressure testing in our specialized chambers, simulating depths up to 6,000 meters (60MPa) to guarantee absolute watertight integrity.
Step 04: Rigorous Pressure Testing
60%
With ISO-certified processes, we move to full-scale production. Each unit is subject to final electrical inspections (insulation resistance >200 MΩ) and wet-plugging durability checks.
Step 05: Mass Production & QC
90%
We provide secure global shipping with comprehensive technical documentation and test reports. Our engineering team remains available for post-deployment support and technical consultation.
Step 06: Logistics & Global Support
100%
