    About Us
    Who We Are

    Founded in 2017, Ningbo Juheng Machinery Technology Co., Ltd. is a precision manufacturing enterprise located in Ningbo, China. We began with a focus on gears, worm gears, and drive shafts, and have since expanded into two core manufacturing divisions: aluminum die casting and precision CNC machining.

    With two modern workshops housing 53 sets of production equipment, we serve the automotive, industrial, consumer electronics, and LED lighting sectors. Our in-house mold making capability, rigorous QC system, and ISO 9001 certification ensure consistent quality from prototyping through mass production.

    We are currently applying for IATF 16949 certification to further strengthen our automotive quality management system.
