We’ve spent 20+ years building water meter mechanisms and complete meters—experience that also sharpened our capabilities in mold design, injection molding, and assembly for small appliances, plastic housings, and precision parts.

Now we apply that know-how to support OEM/ODM partners with fast DFM, rapid tooling, and cost-efficient production—delivered with consistent quality and scalable capacity.

Happy to explore if there’s a fit with your supply chain needs.
