About HAYDU: Who we are

Who We Are

A Legacy of Precision. A Future of Possibility.

HAYDU is more than a manufacturer—we’re a trusted partner in precision. With a legacy dating back to 1936, we’ve spent nearly a century helping visionary companies bring breakthrough technologies to life. Today, as part of MD3 Company LLC, we continue that tradition from our ISO 13485:2016 certified facility in Miramar, Florida.

We specialize in custom manufacturing for the medical, aerospace, and marine industries—delivering everything from prototypes to production-ready assemblies with speed, accuracy, and care.

Our Story

It all began in 1936, when the Haydu family—Hungarian immigrants and master craftsmen—opened a loft shop in Newark, New Jersey. What started with high-speed radio part machines grew into a wartime electronics supplier with its own airstrip and hundreds of employees. Over the decades, the Haydu name became known for ingenuity, precision, and trust.

After relocating to Florida in 1960, HAYDU continued to serve critical industries with unmatched craftsmanship. In 2020, the company was acquired by MD3 LLC, modernized, and positioned for the next era of manufacturing excellence.
