From Foundry Roots to Global Reach

    Our company’s history dates back to the 1980s, beginning with Jin’ji Foundry in Xianxian County, Hebei Province. Over the decades, we have evolved from a basic manhole cover manufacturer into a specialized producer of cast manhole covers, pans, and precision machine parts.

    In 2013, we established a new manhole cover factory in partnership with others, featuring a fully automated production line with an annual capacity of 90,000 tonnes. The facility spans 40 hectares and operates under the ISO 9001 quality management system.

We have built and maintained strong business relationships with clients across Southeast Asia and the Middle East.

    Tianjin Zhengji Machinery and Equipment Co., Ltd. was founded in 2005 and expanded significantly in 2010 with the addition of advanced machining equipment. This machining center provides reliable support for all our casting products.

    Our product portfolio includes manhole covers, pans, and various machine parts. In 2017, we established In Rich Casting, a dedicated trading company focused on exporting our in-house manufactured products. We are headquartered in Tianjin, the largest port city in northern China.
