Automated Disinfection System for Polyethylene Terephthalate Bottles for Bacteria, Fungi, and Virusesinfecting contaminated surfaces. This device makes it possible to disinfect polyethylene terephthalate (PET) bottles by applying short-wave UVC rays from 200 to 280 nm, which generates a germicidal effect. The machine consists of a UVC chamber, transport, and a control system. For this, the methodo

Project-Based Learning in Product Design Engineering: A Case Study of External Gear Pump Design pumps, and one of them is a gear pump, which may be categorized as an external gear pump or an internal gear pump. In the manufacturing industry, external gear pumps are considerably simpler to design than internal gear pumps as the shaft movement is in one place. Several studies are needed to manu

Tool Wear Analysis on Time-Domain and Frequency-Domain Data of Machining S45C Using Signal Processinease of creating complex geometries products. However, the milling process is necessary to use together with a cutting tool to cut material. During that process, it is likely that there would be a deterioration of cutting tools due to temperature or abrasion between tool and materials. To investigat

SHS Extrusion of a Composite Material Based on Aluminum-Magnesium Spinel technological parameters (delay time before applying pressure, strain rate, pressing pressure) and design parameters on the process of SHS extrusion of the studied material, as well as the structure and phase composition of the obtained products, was studied. It has been established that the strain
