In this paper we represent a study reporting the numerical simulation of small-diameter pipes extrusion process. Polypropylene and low density polyethylene were chosen as plastics and a selected transverse head as a tool in the simulations. The aim of the study is to examine the distribution of temperature in the individual sections of the bagasse and tools, in order to optimize the parameters and process flow extrusion and validate the implementation tools, by simulating the flow of plastic by the head.

This paper presents information on the methods of construction and selection of materials, for the manufacturing of a medical device – a syringe filter. The main scope of the research was numerical simulation made in order to optimize the injection process. This simulation comprised of two parts: the first in which the chosen optimal number and position of injection points on the surface, and a second with the chosen optimum wall thickness, using a pre-selected injection points.

The publication describes research on supplements that reduce foil friction in the case of sliding contacts. The supplements added to the LD-PE polymer material were based on the following blends: erucic acid amide, behenic acid amide, colloidal silica, potassium soap and talc. The work contains information on the types of processing additives and the resulting changes in properties in the surface layer of the product in the form of foil.

This paper presents the characteristics of the production of extrudate with axial-symmetrical construction, having a segmented construction wall. Examples of machine tools and devices for manufacturing products with segments and the construction characteristics of a single segment are presented. Methods of shaping the segment wall in forming sockets, characteristics and type of movement made by shaping elements in the process of extrusion in the process line are described. Exemplary results of experimental investigations of the displacement of geometric elements of a single segment and the influence of wall thickness on segment deformation at a given force and speed of deformation under laboratory conditions are presented.
