and the threaded components are made of W6Mo5CR4V2 wear-resistant alloy steel, with a
hardness of HRC60, with conveying blocks, mixing blocks, shearing blocks, banburying blocks,
kneading blocks, countercurrent blocks, building block series components, and the mandrel is
gradually splined and can be combined according to any material ratio to meet the needs of
different extrusion processes
7. Barrel material: The 5-section barrel is made of 45# nitriding steel forgings, lined with a301
wear-resistant alloy sleeve, with hardness of HRC60, and treated by nitriding, quenching and
tempering and ultra precision grinding, with surface roughness Ra ≤ 0.4 μm. Wear and
corrosion resistance
