Because of its unique way of processing and the output ,extruder is gaining popular in feed pro-cessing industry and food manufacturing .Screw is the main component of the extruder , it should bear a huge extrusion pressure in high temperature and high humidity environment .During to the complex curved surface and the shape ,for the moment there is not a particularly good way to the stress analysis or optimization design for it.So it requires us to propose workable solutions to improve the extruder .In this article the screw 3D model is based o...
