TECHNICAL DATA
Incongruous parallel twin screw and barrel ：Φ50-Φ180
Ratio of length to diameter :L/D=16-36
Conical twin screw and barrel :Φ35/72-Φ92/188
1.material: 38CrMoAl A, Nitriding treatment,
surface hardness: HV≥920, Nitriding depth:0.5-0.8mm
2. Material: 38CrMoAlA-based, plasma arc surfacing, layer of compound being 1.5mm, wearing and corrosion resistance, effectively prolong the usage of the barrel and screw.
