Study on Polymer Powder Solid Extrusion Forming

Abstract:

Engineering plastics has many uses, such as national defence, communication and scientific research. In this paper a new experiment plan was proposed in order to get a new engineering plastics forming method. Through the compressive test of polyoxymethylene powder, the process parameters such as temperature, stress and velocity are obtained.Based on the parameters got from compressive test polyoxymethylene powder solid extrusion forming was studied by self-made device. Microscopic analysis and mechanical properties test show that the process parameters are reasonable, the crystallinity increase and molecular chain is oriented along the extrusion direction, as a result the tensile strength and modulus increase greatly.
