The quality of tools and dies is good or bad. The length of service life of them is long or short. They are all the important factors to determine one extrusion technology is economical or desirable, and the development of one new product can be successful. How the extrusion tools and dies are designed will relate to the development of the extrusion industry in the future. This design instruction explain the character of the tools and the dies, the classified construction, the work principle and method and steps of the extrusion tools and dies design, and refer to the die CAD/CAM technology in the extrusion die design. The CAXA electronic painter in is used to design the extrusion dies in two dimension. And the UG NX 3.0 is used to design the extrusion dies in three dimension. In this design instruction , the 4MN extrusion machine is used as the example to design its measurement and parameter of tools and dies, and calibration process. The extrusion tools contain extrusion container, extrusion bar and extrusion band. The extrusion dies contain the one hole die used in producing the XC248profile, the multiplex holes dies used in producing XC045profile, and the prothole die used in producing LX0349 profile. There are many pictures and tables in the instruction to explain the design in detail.
