Relocation of enterprises
After relocating to Zhongshan, Guangxi, MnSteels shift its focus into making jaw crusher plates and making manganese steel part as its primary focus. MnSteels then had 3 500kg furnaces and a small heat treatment furnace.
The second technical transformation
1992-1999 years, Better furnaces with bigger capacities(1000 KGs) replaced the old equipments, MnSteels jaw crusher plates line dominated China's southern market with its superior quality and competitive price.
The development and direction of new products
1999-2005 years, Bigger crushing applications required bigger parts, MnSteels started making heavy weight jaw crusher plates, at the same time, a small engineer team was formed to research on producing high quality cone crusher plates.
The third technical transformation
In the past 2005-2009 years, the company has drawn from the original R & D department to develop new technologies. Finally, the "iron coated sand" and "molten steel refining" were successfully developed and obtained national patents.
Honors of Technology
In July 2010, the "method of casting the broken wall of manganese steel in cone crusher or the method of rolling the mortar wall of a conical crusher" was granted by the national patent in 2011 for the the Great Wall mining machine.
Gaining recognition of international brands
In August 2010, the Great Wall mine became OEM supplier of an international mine brand.
Large products become the sole supplier of a well-known brand.
In October 2010, 5 tons of melting furnace was installed mechanically in the Great Wall, and 5.5 tons of jaw crusher castings were produced successfully. With the use of "high purity steel" technology, the product made us the only supplier of the whole Guangdong market.
Won the "Chinese Foundry Industry 1000 key enterprises" honorary title.
In 2011, the ChangCheng Mechanical miners came to the fore in thirty thousand foundry enterprises all over the country. Won the honorary title of "China's foundry industry thousands of key enterprises" awarded by China Foundry Association.
The cone wall of the cone crusher is collected by the China Foundry Museum as a permanent display
In March 2012, the cone crusher's rolling mortar wall produced by the ChangCheng Mechanical mine was collected by the China Foundry Museum as a permanent display.
Patent technology is identified as "international leader"
In October 2012, "iron mold sand casting technology" and "medium frequency furnace high purity steel smelting technology" were identified as "international advanced" technology, and some of the technology "international lead".
Opening up the international market, the effect is remarkable
In the past 2012-2017 years, the international market has been opened up, and products have taken a place in the international market.
