Shafts play a really decisive role transferring the torque of the drive to the screw segments and hence to the process. Shaft design options are quite limited, because of geometric restrictions. High torque is important to ensure economic production and quality of the end-product. Therefore shafts have to deliver maximum mechanical performance.

Shafts made by C.A.PICARD® offer the optimum performance available using modern material technology. You can make use of the full potential of your twin screw extruder when you take it to the limits.

Materials for shafts:

DFHot-forming steel
DTHeat treated steel
EGHardened stainless steel
D5Special high-alloy steel
D4Heat treated steel
