Product Description
We produce and customize non-standard agricultural machinery parts for many agricultural machinery companies, including castings, processed parts, etc. This product is a cutting tool for agricultural machinery and equipment. The material of its parts is No. 25 steel and it is completed through shell film casting. After casting, tungsten steel blades are welded to the cutting surface to increase the service life of the parts, and finally, anti-rust painting treatment is carried out.
