The screw uses 38CrMoAIA materials that have undergone a tempering and surface nitriding treatment. The surface hardness is HRC60-65 and hard layer thickness is 0.4-0.6mm. The surface roughness is less than Ra0.8. Inside the screw there is a pore path for temperature control circulating water, which serves for the heating and cooling of the screw.
1. The feeding cylinder is mainly composed of the rear body, front bushing and rear bushing. The structure is a jacketed cast iron.
2. The rear body is made of cast steel. It contains a cavity where temperature control circulating water can flow through for the heating and cooling of rear body.
