Abstract: A kind of data collection system for the semi-solid state extrusion process of MMC has been developed by using C language and database technology, which can collect and deal with multiposition data. Its initial parameters can be given by man-machine conversation method. By using this system, many dynamic signals, such as pressure, temperature, displacement, velocity, can be collected. Moreover, the whole process can be tracked and viewed in real-time. Experiments to measure the semi-solid extrusion process show that this system has a good reliability and is easy to operate. So this study has laid a foundation for determining process parameter and implementing process control.
