Production of technological plugs for engine box and oil system using additive technologies

Abstract

Today, technological plugs designed to protect the internal cavities of parts and assembly units are manufactured using such production methods as casting or stamping. At the same time, their subsequent processing is a time-consuming process. Additive technologies can save material, save time and reduce expenses. This study considers the possibility of manufacturing technological plugs for engine box and oil system using additive technologies. The cover plugs were printed using the Fusion Deposition Modeling (FDM) method on a Russian-made ZENIT printer. PLA plastic was chosen for 3D printing. The plug models were optimised, which allowed correcting and reducing the estimated printing time. In particular, some plugs were made assemblable, which helped to avoid a large number of printing supports. The production of technological plugs using additive technology allows reducing the cost of the finished product, the weight of the plugs and the estimated time of their production.

Justification of the Use of Composite Metal-Metal-Polymer Parts for Functional Structures

“…It was also noted that the parts obtained by FDM and SLA by 3D printing methods have anisotropy of properties, which is due to the layer-by-layer technology of material deposition. In [12], FDM additive manufacturing technologies are used to manufacture technological bushings and plugs, that is, for unloaded parts. The use of FDM technologies for the production described in [12,13] mass production is not advisable, so it is more rational to use the technology of molding thermoplastic polymers into metal molds.…”

Evaluation of the Economic Efficiency of the Technology for Manufacturing Composite Metal-Metal-Polymer Parts in Comparison With Additive and Subtractive Technologies

“…Применение таких дисперсно-наполненных ПКМ как металлополимеры, в промышленности часто ограничено ремонтными работами [7][8][9]. Однако металлополимеры, это реактопласты, обладающие для своего класса материалов уникальными свойствами.…”
