How strong is HYSF’s R&D and Intellectual Property capability?

HYSF is a technology-driven enterprise holding over 10 utility model patents and 9 registered trademarks. Our dedicated R&D team focuses on independent technological innovation, enabling us to develop proprietary deep-sea sealing technologies that challenge international monopolies.

Innovation is the core of HYSF. We are not just a manufacturer; we are a National High-Tech Enterprise.

Our R&D Strengths:

Proprietary Technology: We have secured 10+ national patents covering various aspects of watertight interconnect technology. This includes specific patents for our L-Type Watertight Cables, Micro Series, and unique sealing structures.
Import Substitution Strategy: Our R&D mission is to analyze top-tier global products and develop high-performance domestic alternatives. This involves reverse-engineering critical failure points and enhancing material compositions to equal or surpass the lifespan of imported brands.
Continuous Improvement: We constantly upgrade our mold designs and vulcanization processes (High-Temperature Vulcanization) to ensure unibody structural integrity.

This strong IP portfolio ensures that HYSF products are legally secure, unique, and technologically advanced.
