The Development History
During the period of the Sixth and Seventh Five-Year Plan,the company cooperated with Tsinghua University and Shandong Mechanical Design and Research Institute in researching and manufacturing the vermicular graphite cast iron and filled the domestic gap by issuing the industry standard.
In the year 2006, Special Casting Engineering and Technological Research Centers Shandong was officially established by the company. Authorized by Committee of China Foundry Association, the company drew up two items of national standards in the year 2009, one is VERMICULAR GRAPHITE CASTINGS, and the other one is METALLOGRAPHIC TEST STANDARD FOR VERMICULAR GRAPHITE CASTINGS, which were announced on June 16th, 2011 and implemented on March 1st,2012. In addition,We have passed through the GB/T19001----2008 Quality Management System,GB/T24001---2004 Environment Management System, GB/T28001----2011 Occupational Health and Safety Management System Approval and earned many items of national invention patents,dozens of items patents in utility models and designs.

We have customers in India market, such as TATA STEEL LTD., JSW STEEL LIMITED, ESHL, EIL，Southern Iron and Steel Company LTD. We also supply various coke oven equipments and spare parts to the following customers:Nippon Steel Corporation, JFE Steel Corporation ,POSCO, Hyundai Steel, Arcelor Mittal, INC.
As a new material ,the vermicular graphite cast iron ,in the shape of vermicular, makes the vermicular cast iron have the better characteristics in high mechanical strength, heat conductivity ,vibration absorption, plastic and anti-oxidization compared with the ferrosteel, especially the better heat resistant fatigue performance. So now it can be applied in many areas, such as metallurgy, coking, paper, machine tools, automobiles, ships and trade. Many years’practices have proven that the service period of vermicular cast iron castings used for the coke ovens is more than twice as long as those used in the alloy cast iron and so far performances as breaks and deformations have never happened.
Today we have more advanced and perfect manufacturing technique and equipments.The testing method is also more abundant.The quality and technique of our products is changing and improved with each passing day. Our philosophy as “Pragmatic innovation, and the pursuit of excellence” will promote us make more progress and we would like to extend our sincerity to all the friends worldwide to grow together and wish to have an ever-lasting cooperation for a splendid future .
