Series was founded in 2017 with the full backing of Rowhill Investment. Since its inception, the company has remained sharply focused on the niche field of threading technology, guided by the philosophy of "mastering core technologies to create exceptional products, " and is committed to becoming a global leader in the thread drive industry.

Driven by an uncompromising pursuit of precision, Series has built strong in-house R&D and manufacturing capabilities for core equipment. The company independently designs and produces key machinery-including CNC internal thread grinders, CNC external thread grinders, high-precision measuring instruments, and customized thread rolling dies-ensuring quality control at every stage of production and solidifying its global leadership position.

Over the past two decades, Series has continuously refining its expertise and building deep competitive strength. Today, it has established a fully integrated vertical supply chain in threading technology.

Looking ahead to the next twenty years, Series will maintain its strategic foresight and precise market positioning. The company will focus on the ball screw segment, further advancing technological innovation and industrial synergy. By building a more complete industrial ecosystem, Series is dedicated to delivering increasingly competitive products and solutions to customers worldwide-and writing a new chapter in threading technology.
