The R&D team specializing in forging parts designs and develops its own forging processes, analyzes the structural features of forged parts, and continuously optimizes and improves quality.
Only the best materials from large-scale steel mill, such as 40Cr and 20CrMnTi, are selected for production. Some other manufacturers are used scrap rebar or non-standard 45# steel, in order to reduce cost. We strictly control the quality of each component from the source. Only after thorough inspection of the raw materials can they be allowed to enter the factory.
The process of straightening and normalizing the ring parts greatly improves the comprehensive mechanical properties of raw materials. After carburizing, the workpiece is quenched and tempered at low temperature, so that the surface has high hardness and wear resistance, while the heart still maintains good plasticity and toughness, so as to meet the requirements of the use of the workpiece.
There are a number of quality tests for each finished product, in order to ensure the product quality. The static tensile strength (KN) is 50° without deformation. The Rockwell hardness (HRC) of the ground working surface is 48-52 degrees.
In 2007, Tianjin Longshun Metal became the designated supplier of Guangxi Liugong. During the more than ten years of cooperation with Liugong, Longshun Metal has won numerous honors, such as outstanding supplier and best after-market business cooperation award.
