Can I own the Exclusive Rights (IP) to a custom mold?

Yes. If you pay the full Non-Recurring Engineering (NRE) tooling fee, HYSF can sign an Exclusivity Agreement. This guarantees that the specific mold and design are reserved exclusively for your company and will never be sold to your competitors or listed in our public catalog.

We respect your innovation.

Proprietary Design: Many clients develop unique connector shapes to prevent their end-users from using unauthorized third-party cables.
Asset Management: The mold is physically stored in our secure facility, but legally belongs to you. We maintain it and track its shot life.
NDA: This is typically paired with a strict Non-Disclosure Agreement.

With over 15 years of expertise in subsea interconnect technology, I lead HYSF's R&D team in designing high-pressure (60MPa) solutions. My focus is on ensuring zero-leakage reliability for ROVs, AUVs, and offshore instrumentation. I personally oversee the validation of our custom connector prototypes.
