Abstract:

Powerjet Plastic Machinery Co., Ltd achieves cooperation with Mr. Zhang who is professor of high polymer materials science and engineering college in SICHUAN University and makes great efforts to development of pressure vibration injection molding machine.

Powerjet Plastic Machinery Co., Ltd achieves cooperation with Mr. Zhang who is professor of high polymer materials science and engineering college in SICHUAN University and makes great efforts to development of pressure vibration injection molding machine. This is for the study of vibration injection pressure holding effect on polymer processing process, to explore the application of enhancement and the physical and mechanical properties of plastic products.

Professor Zhang is mainly engaged in the research of new method in polymer material processing, and polymer injection molding process in the morphology control and mould CAD/CAE technology. Professor Zhang is the person in charge of State Key Laboratory of polymer materials engineering fund, focuses on polymer materials as research object. He is successful in research of vibration injection and pressure holding, increase pressure vibration in the process of the polymer melt, and finds that with the increase of vibration frequency (more than 1Hz), it will change the rheological properties of polymer melt in the molding process. The melt state is even, and the plasticity of polymer is improved, and thus the quality of products is improved also. In vibration injection at high temperature, toughening and enhancement can be realized simultaneously in products. The pressure vibration injection finally can change the physical and mechanical properties of the products.

In this experiment to explore the required pressure vibration injection molding machine, professor Zhang had visited many domestic brands of machines, and eventually reached cooperation with Powerjet on the base of understanding and deeply mutual trust. According to Professor Zhang’s vibration injection theory, on the basis of BJ50S6, we carry out targeted research and development, the vibration injection pressure reaches 300MPa, vibration frequency 5Hz; parameter and vibration frequency, pressure amplitude can be set in the injection molding machine panel, and we can see the vibration curve in panel. In order to facilitate professor Zhang’s research, we specially reserved the computer interface, which insure the machine can be connected with the computer line through a dedicated connection, to get the vibration injection molding process data. Through all of our departments close cooperation, we achieve ultimate success in the trial and get the preliminary acceptance. Professor Zhang considers the vibration performance is better than expected and satisfied with this machine vibration injection performance. The success in development of this new machine proves that we have the capacity to develop advanced production equipment on the basis of latest polymer molding theory.

Through the cooperation with research institutions, we will develop more and more advanced technology and superior performance machines to meet the growing market demand.
