Design of the PLC Controlling Imprinting Machine for Polymeric Microfluidic Chip

The design of the imprinting machine for polymeric microfluidic chip was introduced.The imprinting machine can be heated and cooled by TEC,pressed by hydraulic pressure in a vacuum maintained by a pump.Realtime control between PC and PLC is realized through serial communication by freeport mode,and the control of temperature and pressure is realized by PLC.It is showed that the experimental results agree with the high quality and precision of the polymeric microfluidic chips made by this machine.
