Heat Treatment of Die and Mould Oriented
Concurrent Design
Abstract: 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 for products.
Key words:die design; heat treatment; mould
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.
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 diverge 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 divergences 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．
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．
1 Heat Treatment Under Concurrent Circumstance
The concurrent pattern differs ultimately from the serial pattern(see Fig．1).With regard
to serial pattern，the designers mostly consider the structure and function of die and mould，
yet hardly consider the consequent process，so that the former mistakes are easily spread
backwards．Meanwhile，the design department rarely communicates with the assembling，
cost accounting and sales departments ． These problems certainly will influence the
development progress of die and mould and the market foreground ．Whereas in the
concurrent pattern，the relations among departments are close，the related departments all
take part in the development progress of die and mould and have close intercommunion with
purchasers．This is propitious to elimination of the conflicts between departments，increase
the efficiency and reduce the cost．

Heat treatment process in the concurrent circumstance is made out not after blueprint
and workpiece taken but during die and mould designing ．In this way ，it is favorable to
optimizing the heat treatment process and making full use of the potential of the materials．
2Integration of Heat Treatment CAD／CAE for Die and Mould
It can be seen from Fig．2 that the process design and simulation of heat treatment are
the core of integration frame．After information input via product design module and heat
treatment process generated via heat treatment CAD and heat treatment CAE module will
automatically divide the mesh for parts drawing ，simulation temperature field
microstructure analysis after heat—treatment and the defect of possible emerging (such as
overheat,over burning)，and then the heat treatment process is judged if the optimization is
made according to the result reappeared by stereoscopic vision technology ．Moreover tool
and clamping apparatus CAD and CAM are integrated into this system．
The concurrent engineering based integration frame can share information with other
branch．That makes for optimizing the heat treatment process and ensuring the process sound．
