In the production of rubber and plastic in the process, a lot of materials that require extremely high precision processing machinery. The only way to be able to meet customer requirements for high end products. The extrusion process have a higher axial force to be absorbed. Hao grams (formerly Parkway) in KLYJ series single screw extruder gearbox is mainly used in plastic extrusion molding, they have high operational reliability and delivery time is short and so on. Standard series gearbox with a thrust bearing mounted in front of the gear box. Extruder can withstand extremely high axial thrust. Output torque range is 1700-100000Nm.
