“…The interactions between these factors result in the difficulty to achieve a uniform distribution by simply changing the process condition parameters. Therefore, applying CAE simulation is a reliable way to quickly identify and fix potential problems before manufacturing 45,46 . In this study, a hexagonal plant‐pot mold was designed and injection molding parameters suitable for PLA material were optimized by Moldex3D CAE simulation (Figure S2).…”

This work aims to study the possibility to process PLA/PBS/RH green composites into hexagonal plant‐pots employing a large‐scale industrial operation using injection molding. Green composites based on poly(lactic acid) (PLA), poly(butylene succinate) (PBS), and rice husk (RH) with various RH contents (10–30%wt.) were produced successfully using a twin‐screw extruder. The compatibility of RH‐matrix was improved by chemical surface modifications using a coupling agent. RH was analyzed as an effective filler for PLA to develop green composites with low cost, high biodegradability, improved processability, and comparable mechanical properties as unfilled PLA. With increasing RH content, tensile modulus of the composites increased gradually. The addition of PBS, at PLA/PBS ratio of 60/40, improved the elongation at break and impact strength of PLARH30 by 55% and 7.1%, respectively. The suitable processing temperatures for PLA decreased from 220–230°C to 170–180°C when 30%wt. RH was composited into PLA matrix and were further reduced when PBS was applied. After biodegradation via either enzymatic degradation or hydrolysis, surface erosion with a large number of voids, mass loss, and the substantial decrease in tensile strength of all the composites were observed. In addition, the biodegradation of the composites has been improved by the addition of either RH or PBS.

“…It is carried out in injection molding machines and with such auxiliary devices as production thermostats, plastic dryers, grinders for grinding plastics, etc. Many papers studied primary molding conditions, from design creation to product manufacturing [ 1 , 2 , 3 , 4 , 5 , 6 , 7 ]. The injection process is influenced by various factors: properties of the material, wear of the mold, temperature fluctuations, parameters of the process [ 8 , 9 , 10 , 11 , 12 ].…”

This paper presents the computer simulations of the injection process of elements used in electromechanical devices and an analysis of the impact of the injection molding process parameters on the quality of moldings. The study of the process was performed in Autodesk Simulation Moldflow Insight 2021. The setting of the injection process of the detail must be based on the material and process technological card data and knowledge of the injection molding machine work. The supervision of production quality in the case of injection moldings is based on the information and requirements received from the customer. The main goal of the analysis is to answer the question: how to properly set up the process of filling the mold cavities in order to meet the quality requirements of the presented molding. In this paper, the simulation was compared with the real process. It is extremely important to optimize the injection, including synchronizing all process parameters. Incorrectly selected values of the parameters may lead to product defects, leading to losses and destruction of raw materials, and unnecessary energy consumption connected with the process.

“…To address this challenge, a method for the design of reconfigurable moulds with the integration of Computer-Aided Engineering (CAE) and Design for Assembly (DfA) techniques is here introduced. CAE became a reliable technique in the last decades [5][6][7]. In industry, the IM simulation is mainly limited to cavity filling verification and design validation.…”

The injection moulding process enables the production of complex shaped parts, thanks to the accurate kinematics and the tight tolerances of the mould. This process is suitable for large batch production, leading to reduced single part costs, but involves high initial investments. The life of a mould can be increased by exploiting reconfigurable cavity inserts. So, a design method has been conceived for reconfigurable injection moulds by integrating Design for Assembly and Computer Aided Engineering techniques. From the early phases of a systematic design approach, the simulation models are configured with the different geometries as requested by design specifications. The mould inserts are designed with standard features in order to be quickly changed. A case study on a reconfigurable mould for the overmoulding of polymer wheels to be produced in different sizes is presented. The simulations with Moldex3D software are finally compared with the experimental data from the actual production.
