Advantages of cold rolling mandrel compared with traditional spline milling:
It is a qualitative leap in spline machining process that the advanced cold extrusion process is used to replace the traditional mechanical cutting method. It not only improves the machining accuracy and surface finish, but also greatly improves the mechanical properties of parts.
The cold work hardening of metal after cold extrusion and the formation of reasonable fiber streamline distribution in the parts make the strength of spline much higher than that of mechanical cutting.
Through the test, the bearing torque of the mandrel processed by this process is increased by 25-30%, and the accuracy is improved by two levels, reaching the international level 6 accuracy. In addition, the reasonable cold extrusion process can form compressive stress on the surface of the parts and improve the fatigue strength.
High toughness and strength
Strong comprehensive performance, able to bear high torque, necessary for extruder
Fine processing, involute spline coaxiality ≤ 0.05mm
Cold rolling mandrel
Product introduction:
Designed for high-end users of twin-screw extruder: high torque, high strength and high precision extruder mandrel
With the development of twin-screw extruder towards high speed and high torque, higher requirements are put forward for the strength (especially thermal strength) and accuracy of the mandrel of twin-screw extruder. Through extensive investigation and painstaking research, our company adopts pre hard alloy tool steel imported from Germany and cold rolling processing equipment imported from Europe for spline processing. After customer trial, our products fully meet the performance and quality requirements of similar high-end products imported from abroad.

2: Advantages of cold rolling mandrel compared with traditional cutting mandrel
Cold extrusion spline processing:
Using advanced cold extrusion technology to replace the traditional mechanical cutting method to process splines is a qualitative leap in spline processing technology. It not only improves the machining accuracy and surface finish, but also greatly improves the mechanical properties of parts.
The cold work hardening of the metal after cold extrusion and the formation of reasonable fiber streamline distribution in the parts make the strength of the spline much higher than that processed by mechanical cutting.
Through the test, the bearing torque of the mandrel processed by this process is increased by 25 ~ 30%, and the accuracy is improved by two levels, reaching the accuracy of grade 6 of the national standard. In addition, a reasonable cold extrusion process can form compressive stress on the surface of the parts and improve the fatigue strength.
