Naning Qiming Machinery Co.Ltd

Qiming Machinery is the leading manganese steel, chromium steel, alloy steel, and heat-resisting steel manufacturer in China.

Since 1993 years, Qiming Machinery’s mission has remained the same: To respond to industrial wear part challenges, deliver innovative wear parts with outstanding wear life, supply the best quality and longest lifetime wear parts for cement industry, mining industry, the coal industry, and others.

On the other hand, we also help our customers to find the best suitable material for their wear parts and redesign and improve new wear resistance material for all the customers.

Extreme temperatures, high-impact work, and tough materials wreak havoc on wear parts, and the frequent replacement and maintenance of these parts waste huge amounts of time and money.

Qiming Machinery wear parts last longer than other products on the market are easy to install and maintain, minimizing downtime on-site while maximizing operations’ profitability.
