our tungsten ball producing equipment: 

The introduction of cemented carbide production equipment:

1. spray drying: with high purity nitrigen protection in a fully enclosed environment, the mixture oxygen are effectively reduced, material purity are effective guaranteed. material dirty are prevented.

2. CIP: using 3000Mpa isostatic press, the defects are effectively stopped. offering a good environment to get blanks with uniform pressed dencity.

3.the maximum sintering pressure can reach 100kg, eliminated the internal voids of alloy body effectively and get the high hardness and high strength carbide blank with good densification.

4. effectively improve the alloy microstructure, so that alloy internal stress can be effectively eliminated.

5. hational grade detection center, all kinds of thorough performance detecting. using the ultrasonic technic, the stable quality of massive article are guaranteed.

Zhuzhou Jingzuan Carbide Co., Ltd, which is committed to R&D, producing and sale the GB A Class high-grade cemented carbide series products, is the only one modern high-tech enterprise in China. 

GB A Class high-grade cemented carbide has 3 technical features: raw material is the original raw material of high purity tungsten carbide powder, foundation is the high-precision technology equipment and indemnification is the strict 7 degree quality inspection system. 

These features make our cemented carbide products superior than other products so that our company has been choosing by Xiangtan Iron and Steel Co., Ltd. (XISC), SANY Heavy Industry Co., Ltd., Weichai Power Co., Ltd., CSR Co., Ltd., Anhui Military Industry Group Holding Co., Ltd. and other companies as their quality suppliers. 

Our products are exported to Southeast Asia and the Americas and enjoy a high popularity in those markets.
