The application of bamboo by-products such as bamboo branches, chips to recycle and produce pressed bamboo pulp is an urgent task in Vietnam. It perfectly replaces natural wood with artificial wood embryos from bamboo powder, which has both economic benefits of reserving the source of raw materials, environmental protection The paper presents a study on the influence of technological parameters on the tensile strength of pressed bamboo plastic fiber that is a new product of a project of our laboratory.
Currently, the research on the application of Single point incremental forming technology (SPIF) in Vietnam is limited. Therefore, the study of technology and equipment for the fabrication of SPIF machine and research on the ability of deformation of the formed material sheet is necessary and should be urgently carried out. The paper proposes a new approach to modularizing the structure of the Single point incremental forming machine by using standard parts, thereby improving the quality and reducing the cost of the machine and improving accuracy of the machine.
Nowadays Single Point Incremental Forming (SPIF) is really a new technology of forming metal sheet after its formation and long development in about five decades. Although it was invented in, 1967 by Leszak, an American inventor, but the applications of the innovative technology have just been popular from 1990 because of the advance of controlling technology. This technology is especially adapted to small batch, unique or single productions. In almost all cases, the workpiece material sheets are metal such as aluminum alloys, bronze, mild steel, stainless steel and even Titanium with lot of researches, papers and thesis... Nonmetal sheets are rarely applied in this technology because of rare application. Nowadays, on the rise of the development of composite materials such as, PVC, thermoplastic resins... that have been a lot of applications on living life and technology. In this paper, we dedicate all of our work in the examination some parameters of forming that influence on the deformable ability of PVC plastic by empirical method under the support of DOE and Minitab software. This paper also provides our own experiences in forming PVC sheet that we had performed in the recent decade.
