A dosed-loop variable piston pump can satisfy the requirement of a modem high performance plastic injection machine because it has many advantages such as high control precision, good following and dynamic performance. In this paper, we first established such a pump system, and illustrated the composition of the system. Then, we carried out an experiment and presented the experimental results. The results indicate that the closedloop variable piston pump has high control precision, good following characters, rapid and accurate dynamics quality and abundant amplitude-frequency width ; it can meet the requirement of high precision injection.
