The shaft is made of high-strength alloy steel and has sufficient strength and rigidity to
withstand the huge torque and pressure during the extrusion process. It is machined with
spiral grooves that cooperate with the spiral blades of the screw to form a channel for material
transportation and mixing. It is connected to the drive device and transmits the power of the
motor to the screw to make the screw rotate and realize the transportation and mixing of
materials.

The torque can reach 10-11, but the performance will decline when the temperature exceeds 250 degrees. The higher the temperature, the greater the performance decline. |
| 17-4PH( 1.4548) | Its performance is superior to that of WR5 and does not decline within 350 degrees |
| WR15E | It is used in industries that can withstand higher torque, with the torque reaching 13-15 |
| IN718 | Nickel alloys have the highest torque in this industry, but they are expensive and are mainly used in high-temperature industries |
Bloom Suzhou Materials manufactures barrels for co-rotating twin screw extruders ranging
from 12 mm to 350 mm. Our screw element is designed to work seamlessly with parallel
twin screw barrels, screw barrels, and twin screw extruders, making your daily production
more efficient.
We melting raw materials of nickel-based alloy powder and HIP powder metallurgy materials
by ourselves, and adjusting the hardness by adjusting the ratio and composition of the metal,
which makes its life time double or triple increased. Based with strong technical force, excellent
processing equipment, advanced production technology, strict inspection system and perfect
after-sales service, Bloom has been a leading supplier in Plastic extruder accessories.
