Sheet Forming via Limiting Dome Height (LDH) Test: Influence of the Application of Lubricants, Location and Sheet Thickness on the Micro-Mechanical Properties of X8CrMnNi19-6-3

Autor: Martin Ovsik, Martin Bednarik, Martin Reznicek, Michal Stanek

Publikováno v: Lubricants, Vol 12, Iss 7, p 260 (2024)

This work is concerned with forming, specifically deep drawing, and its influence on the micro-mechanical properties of sheet metal. In practice, there are several applications in which fractions can occur due to weak spots in the deep-drawn sheet me

Influence of Polymer Flow on Polypropylene Morphology, Micro-Mechanical, and Tribological Properties of Injected Part

Autor: Martin Ovsik, Klara Fucikova, Lukas Manas, Michal Stanek

Publikováno v: Lubricants, Vol 12, Iss 6, p 202 (2024)

This research investigates the micro-mechanical and tribological properties of injection-molded parts made from polypropylene. The tribological properties of polymers are a very interesting area of research. Understanding tribological processes is ve

Tribological and Micro-Mechanical Properties of Injected Polypropylene Modified by Electron Radiation

Autor: Martin Ovsik, Michal Stanek, Adam Dockal

Publikováno v: Lubricants, Vol 11, Iss 7, p 296 (2023)

Today, more and more importance is given to the improvement of polymer materials’ wear resistance, i.e., their micro-mechanical and tribological properties, which could widen their application in practice. The properties of materials can be modifie

INJECTION MOLDING OF POLYCARBONATE THICK-WALLED PARTS USING A TOOL WITH VARIOUSLY DESIGNED GATE INSERTS

Autor: null Jiri Vanek, null Michal Stanek, null Martin Ovsik, Vlastimil Chalupa

Publikováno v: Materiali in Tehnologije. 57

Injection molding is an advantageous technology for the mass production of plastic parts without the necessity for additional procedures. The applicability of this method is still partially limited by the required properties of the manufactured parts

Design of dual-head 3D printer

Autor: Vlastimil Chalupa, Michal Stanek, Jiří Vanek, Jan Strnad, Martin Ovsik

Publikováno v: Manufacturing Technology

Fused Filament Fabrication (FFF) printers are usually designed to create a product with one single material. Some of them allow fabricating items in multiple colours but creating a single product consisting of two different materials remains an advan

Acta Polytechnica CTU Proceedings, Vol 27, Iss 0, Pp 116-120 (2020)

Cross-linking is a process in which polymer chains are associated through chemical bonds. Radiation, which penetrated through specimens and reacted with the cross-linking agent, gradually formed cross-linking (3D net), first in the surface layer and
