HK Series Co Rotating Twin screw extruder

Overview of HK Series Co Rotating Twin screw extruder


Nanjing KY provides more material selection for the process parts of HK Series Twin screw extruder. Besides standard nitriding steel and tool steel, the HIP materials made in China also provide higher wear resistance for machines. Different corrosive powder metallurgy materials are also applied to screw element and cylinder bushing manufacture, and their properties are very close to the same. Class, I imported products, is a very cost-effective solution.

Your Premier Twin Screw Extruder Manufacturer——KY


  • HK Series Twin screw extruder process components, such as screw and cylinder, can be interchanged with AK or SK specifications, and the geometric design is completely consistent. This also means that customers of Nanjing KY AK or SK can seamlessly transfer the original products to newly purchased HK equipment, to achieve higher output or better return on investment.


  • HK Series Twin screw extruder is a medium-high torque and high-speed extruder launched by Nanjing KY in recent years to meet the new needs of customers. It has gained a huge market share and currently produces more than 120 extruders annually.


  • HK transmission system based on Nanjing KY independently developed high-torque gearbox adopts the leading transmission technology in the industry, strengthens the output system of the gearbox with enhanced structure, achieves the ideal result of pure torque output with parallel biaxial output, and greatly improves the safety of gearbox. The transmission parts can be manufactured by German or British torque limiter so that gearboxes and process parts can be safely protected when the torque exceeds the standard.
