“…The main advantage of using the CAx systems is a shortening of the product's time development. The ability to perform many types of CAE analyses [8][9][10][11][12][13][14][15][16] allows to better fit the project assumptions. The applications of CAx systems used in manufacturing and CNC area are outlined in many papers [17][18][19][20][21].…”

The purpose of the paper is to present the design of a new plastic part and injection process simulation. Workflow in virtual modelling and simulations in CAx system was presented on an example of the trolley plastic car for kids. The model of the plastic car was designed and simulated to determine the injection parameters in SolidWorks environment. Based on the 3D model of the product the mould tool was created. From the virtual testing the most suitable injection point location, material temperature as well as the fill time and required injection pressure have been specified. With these results the designers can avoid anomalies or defects in real plastic things with the actual injection process parameters, like: air traps, weld lines and sink marks. Such analyses allow the designer to develop a proper mould 3D model, to save the mould setup time as well as to reduce the cost for manufacturing the mould.

“…The main reason of using CAx tools is primarily reduction time-to-market of new product. CAE analyses [20][21][22][23][24], CAM and CNC manufacturing techniques [25][26][27][28] allow to faster and better fit of the design assumptions. The Reverse Engineering (RE) methods can be used to accurately reproduce free-form shapes using non-contact [29] and contact [30] measurement techniques.…”

The process of polymer injection moulding is complex and complicated, therefore it is characterised by a number of technological and material parametersthat influence the product quality. Setting the best injection conditions requires knowledge of the processing properties of the material, mould shape and technological capacity of the injection moulding machine. Injection shrinkage, as undesirable phenomenon, causes changes of the shape and dimensions of the injection moulding; therefore, it is one of the most important problems that have to be solved, both at the phase of mould designing and at selecting the technological parameters of injection. The paper presents classification of injection moulding shrinkage as well as factors influencing the value of the shrinkage. The conducted experimental tests were related to selected topics connected with the injection process and took into account the change of the processed material characteristics (type and amount of filler) and change of certain, relatively the simplest to regulate, injecting parameters (injection time and cooling of the piece in a mould). Geometrical dimensions of the injection mouldings produced from polypropylene filled with glass fibre were measured using two methods: tactile (electronic measuring instrument) and contactless (3D scanning). The analysis of injection shrinkage illustrates that an effective influence on its value is possible by both choosing appropriate conditions of the injection within the technical range of the machine, as well as, if needed, the processing properties of material can be modified in order to obtain a moulded piece of set geometrical and strength properties. After the analysis of the results, the connection between the injection moulding shrinkage and the content of the filler and the chosen parameters of injection was established.

“…These elements are intended to modify the microstructure of the weld metal deposit. Because of their higher strength and toughness, AHSS steels usually require 25 to 30% more power in the forming process in comparison with low-alloy steels [3]. These steels are also characterized by a low sulfur content (0.01% S), which increases the impact toughness of steel and weld [4].…”

This paper focuses on the weldability of advanced high-strength steels (AHSS), commonly used by the automotive industry and civil engineering. These steels have found application in the construction of mobile platforms mounted on vehicles. AHSS significantly outperform other materials when it comes to performance flexibility and mass reduction potential. This article verifies whether the application of micro-jet cooling technology during the welding process might help to overcome these issues. The aim of this article is to choose welding parameters in the process with micro-jet cooling to obtain the best mechanical properties of the welded structure (elongation). The best welding parameters for these difficult-to-weld constructions are presented in detail.
