TECHNICAL DATA
1. Incongruous parallel twin screw and barrel: : 50-180
2. Ratio of length to diameter: L/D=16-36
3. Conical twin screw and barrel: 35-105
1. Material: 38CrMoAl A, Nitriding treatment, surface hardness: HV920, 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.
