Abstract:
This study is focused on the effects of process parameters in plastic injection molding towards shrinkage and warpage problem of High Density Polyethylene (HDPE) specimen. The aim was to identify the main effects of different process parameters on warpage and shrinkage defects via numerical simulation software and experimental validation. Series of simulations were carried out using Cadmould 3D-F in order to utilize the combination of process parameters based on three level of L9 Taguchi orthogonal design. The Signal to Noise (S/N) ratio and the Analysis of Variance (ANOVA) were used to optimize the levels and to point out the impact of the process parameters on warpage and shrinkage. From the results, it showed that the most affected parameter on the warpage and shrinkage is packing time, with the P value of 48.93%, followed by melting temperature with 40.58%. The filling time and packing pressure were not a significant factor because they only contribute 7.30% and 3.19% of P value, respectively.

Abstract:
The objective of this study is to analyze the main parameter setting in injection moulding that influenced the processing of selected thermoplastics components. The test sample used for this project was a hinge made from Polypropylene (PP). This sample was being utilised to analyse the parameters affecting the quality of plastic products, which were warpage and shrinkage. Computer-Aided Engineering (CAE) was applied through CadMould 3D-F simulation software. The processing parameters such as filling time, melt temperature, wall temperature and cooling time were selected to determine the quality of the product. By adopting Taguchi Method, the orthogonal array, Signal-to-Noise (S/N) ratio and Analysis of Variance (ANOVA) were used to find the optimum levels as well as to indicate the impact of the process parameters on warpage and shrinkage. The verification test was also performed to prove the effectiveness of Taguchi technique after the optimum levels of process parameters. The ANOVA results show that cooling time and wall temperature are found to be the most significant factors for shrinkage and warpage, with the contribution of 66.96% and 56.82% respectively. The verification test with the optimal settings shows that warpage were improved by about 0.4% and shrinkage with 4.2% improvement. These findings are useful for production engineer to determine optimal parameter during performing injection moulding on hinges products.

Abstract:
This paper presents the assumptions of a thermodynamic equation of state for polymers according to the Renner model. The experiments involved extruding a biocomposite based on poly(butylene succinate) that was filled with ground wheat bran with its size not exceeding 200 μm. The biocomposite was produced in pellet form with three different contents by weight of wheat bran, i.e., 10%, 30% and 50%. All specimens were examined for their thermodynamic p-v-T characteristics. Taking advantage of the SimFit module of Cadmould 3D-F, experimental results were used to determine the coefficients of thermodynamic equation of state for the tested biocomposite according to the Renner model. The coefficients were then used to calculate transition temperature and to create diagrams illustrating the relationship between pressure, temperature and specific volume for the tested biocomposite. The obtained results can serve as a basis for assessing the suitability of the biocomposite for injection molding, selecting technological parameters of this process, as well as for analyzing shrinkage and defects of injection-molded parts.

Abstract:
This paper contains a description of tests including the simulation of the injection moulding of thin-walled products. The simulation was designed to analyse the potential impact of processing conditions and cooling conditions on the defects of thin-walled products of the body of the syringe. In order to obtain the correct results, the analysis was based on a simulation comparison with the data obtained after the injection mouldings were produced. Four cases were considered - parameters with reduced injection pressure and absence of pressure push, with a reduced temperature of the injection mould. The test results were analysed in conditions compliant with the recommendations of the production card and with the parameters optimised by computational algorithms of the computer programme. Simulations were carried out using the Simcon CadMould 3D-F programme. The paper describes the construction of a thin-walled body, which is the main segment of a medical instrument - a medical syringe. Also described in the paper are the process of injection of polymer materials and the characteristics of the production of medical syringes. In addition the computer programme software for the simulation of production processes was presented.

Abstract:
The article deals with the basic technological aspects of injection moulding, pointing to the importance of correct product geometry design. Large differences in the wall thickness of the mould result in uneven cooling, material shrinkage, and the formation of internal stress. This ultimately may give rise to deformations, such as those in form sink marks, and may affect the required quality of the mould. The article describes the application of a specific example of one of the ways of correction of the mould wall thickness used in technological practice of the injection moulding technology. This is a case of employing the method of the so-called relief pins. After the introduction of the proposed modification of the form, the mould quality has improved, thereby increasing the production efficiency in the process of shape optimization of manufacturing the product called Installation Box Series S-BOX 106 made of polyamide PA 66. In addressing the issue, simulation of cooling plastic and injection pressure in Cadmold 3D-f software was employed.

Abstract:
The aim of this diploma thesis is to ascertain the process of injecting the wax through an injection moulding machine under certain input conditions and with the help of the simulation program Cadmould 3D-F®, to perfect the injection and the following solidification of the wax. Only thanks to a perfect injection and the following solidification of the wax, a precise wax pattern can be made. In order to compare the process of injecting the wax mixture, we are helped by the Cadmould 3D-F® simulation program and the records of the injection taken by a video camera. In this thesis a simulation program used when simulating the injection of plastics was applied, as a means of comparison. In this case the similarity between the rheological characteristics of both wax and plastic was exploited.
