【 Zhejiang Yongzhu Casting Technology Co., Ltd., formerly known as Hangzhou Higer Metal Products Co., Ltd., 】
Meet Our Founder
I’m Lai Haijiang, founder of Yongzhu Casting. Since 2004, I’ve led our factory to specialize in aluminum die casting, starting from mold making and gradually building full in-house capabilities.
Over the past 20 years, we’ve grown from a 3-person workshop to a factory that now serves clients in over 30 countries, supplying custom aluminum parts for automotive, energy, lighting, and medical industries.
I believe quality comes from control. That’s why I’ve insisted on building every part of production—tooling, casting, machining, finishing—within our own facility. No outsourcing, no compromises.
When you work with Yongzhu, you don’t just get parts. You get engineering support, short lead times, and direct responsibility from a real manufacturer.
