SHENYANG JINFENG SPECIAL EQUIPMENT CO., LTD.
Shenyang Jinfeng company, founded in October 1993, has always been committed to the research and development, the production, and the sales of the key consumable spare parts for large-scale extrusion granulation equipment. Shenyang Jinfeng owns 3 wholly-owned subsidiaries: Shenyang Jinfeng Special Equipment Co. Ltd., Shenyang Jinfeng Special Cutting Tools Co. Ltd., Shenyang Jinfeng Science and Technology Holdings Co. Ltd. And we are developing to a group company.Shenyang Jinfeng is a manufacturing enterprise in the petrochemical granulation equipment spare parts field. It has established long-term and stable business cooperation with PetroChina, CNOOC, Coal Chemical Group and other domestic and foreign large and medium-sized chemical enterprises. The main products of Shenyang Jinfeng company include metal-ceramic composite pelletizing knives (designing and manufacturing), granulation die plates(designing, manufacturing, refurbishing, hard face replacing, capacity expanding and changing steam heating system to oil heating system), pelletizing knife holders (designing, manufacturing and refurbishing). The company can also provide corresponding services such as start-up of the granulation unit and the resolution to the granulation abnormalities. Meanwhile, we could provide rotary jet pumps, extruder booster gear pump bearings, granulator bearing chamber assemblies, heat insulation sealing gaskets for the die plates and other granulation unit related products.
FAQ
