Cold stamping die design to master the basic skills to understand how to mold parts of the process of analysis and how to determine the technology program to understand the basic structure of the mold to enhance the computing power, graphics capability, familiar with the norms and standards, At the same time, there are various courses related to a comprehensive review, the ability to think independently improved. . The use of drawing die design and manufacture of simple mold. Drawing effective and can greatly improve the production efficiency. The design is divided into 5 chapters on analysis of the product technology, technical computing, design templates and components, mold legislation and other issues group.The students should understand the product uses, and the process of stamping parts and dimension tolerance level analysis, the structure of some unreasonable or stamping process of the bad ones, and we need to consult the views of teachers and mapping tool to improve the overall map and non-standard Parts items.
