(3)Mold software applications , networking trend
With the mold in the enterprise competition , cooperation , production and management , globalization , internationalization , and the rapid development of computer hardware and software and software technology , the Internet has made in the mold industry , virtual design , and agile manufacturing technology both necessary and possible.
4.Heat Treatment of Die
Heat treatment of die and mould is as important as design , manufacture and assembly because it has a vital effect on manufacture , assembly and service life . Design and manufacture of die and mould have progressed rapidly, but heat treatment lagged seriously behind them . As die and mould industry develops , heat treatment must ensure die and mould there are good state of manufacture , assembly and wear-resistant properties by request . Impertinent heat treatment can influence die and mould manufacturing such as over-hard and-soft and assembly . Traditionally the heat treatment process was made out according to the methods and properties brought forward by designer . This could make the designers of die and mould and heat treatment perge from each other , for the designers of die and mould could not fully realize heat treatment process and materials properties , and contrarily the designers rarely understood the service environment and designing thought . These pergences will impact the progress of die and mould to a great extent . Accordingly , if the process design of heat treatment is considered in the early designing stage , the aims of shortening development period , reducing cost and stabilizing quality will be achieved and the sublimation of development pattern from serial to concurrent will be realized .
5.Summary
The 21st century , in the new situation of economic globalization , with capital , technology and labor market re-integration of equipment manufacturing in China after joining the WTO will become the world’s equipment manufacturing base . In the modern manufacturing industry , no matter which industry . In order to meet the user’s high-precision mold manufacturing , short delivery time , the urgent demand low-cost , mold industry is extensive application of modern advanced manufacturing technology to speed up the mold industry , technological progress , to meet the basic sectors of the mold process equipment urgent needs.

 Many disadvantages exist in the traditional die design method which belongs to serial pattern . It is well known that heat treatment is highly important to the dies . A new idea of concurrent design for heat treatment process of die and mould was developed in order to overcome the existent shortcomings of heat treatment process . Heat treatment CAD/CAE was integrated with concurrent circumstance and the relevant model was built . These investigations can remarkably improve efficiency , reduce cost and ensure quality of R and D products.
Traditional die  and mould design ,mainly by experience  or semi—experience，is isolated from manufacturing process .Before the design is finalized， the scheme of die and mould is usually modified time and again， thus some disadvantages come into being ,such as long development period ,high cost and uncertain practical effect .Due to strong desires for precision ,service life ,development period and cost ,modern die and mould should be designed and manufactured perfectly .Therefore more and more advanced technologies and innovations have been applied, for example, concurrent ,engineering ,agile manufacturing virtual manufacturing ,collaborative design ,etc. Concurrent engineering takes computer integration system as a carrier ,at the very start subsequent each stage and factors have been considered such as manufacturing，heat treating，properties and so forth in order to avoid the error．The concurrent pattern has dismissed the defect of serial pattern ,which bring about a revolution against serial pattern． In the present work．the heat treatment was integrated into the concurrent circumstance of the die and mould development，and  the  systemic and profound research was performed． 冲压模具英文文献和中文翻译(2):http://www.751com.cn/renwushu/lunwen_4504.html
