However, solids conveying is a key aspect for processes with high screw speeds, grooved feed sections, small screw diameters and material with low bulk density. In injection moulding, throughput limitations are highly relevant in packaging applications as due to low cooling times, plasticizing affects the cycle time. In addition, insufficient solids conveying is a primary cause for air residues in the melt and final product. Therefore, well-designed feed sections are required, especially as direct processing of regrind in recycling applications becomes more relevant due to governmental restrictions. Existing models for injection moulding are based on analytical equations and do not allow to assess new feed sections and feed opening designs, adapted to high screw speeds or regrind. In this paper, numerical simulations based on the Discrete Element Method (DEM), previously used in the field of extrusion, are carried out. In order to replicate the cyclic, superimposed rotation and translation of the screw, a coupled approach of DEM and Multibody Systems Simulation (MBS) is pursued. To verify the accuracy of such coupled simulations, a special test setup is added to a conventional injection moulding machine. Pure solids conveying is investigated, as DEM does not accommodate for large plastic deformations or melting. Different screw and intake designs as well as smooth and grooved barrels are investigated. Selected resins, pellet shapes and regrind are processed, varying the processing parameters and comparing the results to the simulation. The coupled approach replicates reality well in terms of throughput, confirming that DEM can be utilised to further investigate process phenomena and develop calculation models for solids conveying in injection moulding." author: - first_name: Jan full_name: Landgräber, Jan id: '64499' last_name: Landgräber - first_name: Volker full_name: Schöppner, Volker id: '20530' last_name: Schöppner - first_name: Florian full_name: Brüning, Florian id: '72920' last_name: Brüning citation: ama: Landgräber J, Schöppner V, Brüning F.

In previous studies, a mathematical model was developed to predict the degradation while compounding on different twin-screw extruder sizes. Additionally, the examination of filled PPs was conducted. To this end, a range of operating parameters and extruder sizes were used to process PP, and the molar mass was then determined by melt flow rate (MFR) and gel permeation chromatography (GPC) measurements to derive the degree of degradation. The model was then modified by adjusting the sensitivity parameters to allow the degradation behavior of the PPs to be described independently of extruder size. Consistent with prior research, comprehensive measurements of a PP/titanium dioxide (TiO2) compound revealed that, with a few exceptions, increasing temperatures and screw speeds and decreasing throughputs generally resulted in higher degradation. However, the application of the model to the compounds did not achieve good agreement with the measured degradation, indicating different degradation conditions due to the different thermodynamic and rheological properties of the compounds. article_number: '1509' author: - first_name: Paul full_name: Albrecht, Paul id: '90467' last_name: Albrecht - first_name: Matthias full_name: Altepeter, Matthias last_name: Altepeter - first_name: Florian full_name: Brüning, Florian id: '72920' last_name: Brüning citation: ama: Albrecht P, Altepeter M, Brüning F.

Traditional mold cleaning methods often require complete tool disassembly, extended downtime, and heavy use of solvents, resulting in high energy costs and environmental impact. This study presents a novel localized ultrasonic cleaning process for injection molding tools that enables targeted, in situ cleaning of mold cavities without removing the tool from the press. A precisely positioned ultrasonic transducer delivers cleaning energy directly to contaminated areas, eliminating the need for complete mold removal. Multiple cleaning agents, including alkaline and organic acid solutions, were evaluated for their effectiveness in combination with ultrasonic excitation. Surface roughness measurements were used to assess cleaning performance over repeated contamination and cleaning cycles. Although initial tests were performed manually in the lab, results indicate that the method can be scaled up and automated effectively. This process offers a promising path toward energy-efficient, low-emission tool maintenance across a wide range of injection molding applications. article_number: '354' article_type: original author: - first_name: Deviprasad full_name: Chalicheemalapalli Jayasankar, Deviprasad id: '49504' last_name: Chalicheemalapalli Jayasankar orcid: https://orcid.org/ 0000-0002-3446-2444 - first_name: Thomas full_name: Tröster, Thomas id: '553' last_name: Tröster - first_name: Thorsten full_name: Marten, Thorsten last_name: Marten citation: ama: 'Chalicheemalapalli Jayasankar D, Tröster T, Marten T.

Work hardened steel alloys are commonly used for lightweight applications, but they face stability issues when the material thickness reaches certain thresholds. Fiber Reinforced Plastics (FRP) offer a viable alternative due to their high strength-to-weight ratio, but they are often expensive due to long production cycles and high material costs. A feasible solution lies in hybrid lightweight designs that utilize expensive FRP materials only in highly stressed areas, achieving a balance between low mass and acceptable cost. These hybrid structures are lighter than metal components and more cost-effective compared to fully FRP structures, without compromising mechanical properties. This study focuses on producing rotationally symmetrical hybrid structures using Resin Transfer Molding (RTM) combined with vacuum assistance in a single-stage process. The research examines the effects of injection pressure, mold temperature, and the interface between metal and FRP. The mechanical characterization of these hybrid structures was conducted to assess their performance under torsion, compression, and interlaminar shear strength (ILSS) loading conditions. The results indicate that hybrid designs can offer a lightweight alternative without compromising mechanical properties. author: - first_name: Deviprasad full_name: Chalicheemalapalli Jayasankar, Deviprasad id: '49504' last_name: Chalicheemalapalli Jayasankar orcid: https://orcid.org/ 0000-0002-3446-2444 - first_name: Thomas full_name: Tröster, Thomas id: '553' last_name: Tröster - first_name: Manel full_name: Ellouz, Manel last_name: Ellouz - first_name: Thomas full_name: Kordisch, Thomas last_name: Kordisch citation: ama: Chalicheemalapalli Jayasankar D, Tröster T, Ellouz M, Kordisch T.

To address this, the industry is focusing on lightweight components that reduce weight without compromising mechanical properties, which are essential for passenger safety. Hybrid designs offer an effective solution by combining weight reduction with improved mechanical performance and functional integration. This study focuses on a one-step manufacturing process that integrates forming and bonding of hybrid systems using compression molding. This approach reduces production time and costs compared to traditional methods. Conventional Post-Mold Assembly (PMA) processes require two separate steps to combine fiber-reinforced plastic (FRP) structures with metal components. In contrast, the novel In-Mold Assembly (IMA) process developed in this study combines forming and bonding in a single step. In the IMA process, glass-mat-reinforced thermoplastic (GMT) is simultaneously formed and bonded between two metal belts during compression molding. The GMT core provides stiffening and load transmission between the metal belts, which handle tensile and compressive stresses. This method allows to produce hybrid structures with optimized material distribution for load-bearing and functional performance. The process was validated by producing a lightweight hybrid brake pedal. Demonstrating its potential for efficient and sustainable automotive production, the developed hybrid brake pedal achieved a 35% weight reduction compared to the steel reference while maintaining mechanical performance under quasi-static loading article_number: '1644' author: - first_name: Deviprasad full_name: Chalicheemalapalli Jayasankar, Deviprasad id: '49504' last_name: Chalicheemalapalli Jayasankar orcid: https://orcid.org/ 0000-0002-3446-2444 - first_name: Tim full_name: Stallmeister, Tim id: '45538' last_name: Stallmeister - first_name: Julian Janick Stefan full_name: Lückenkötter, Julian Janick Stefan id: '45543' last_name: Lückenkötter - first_name: Thomas full_name: Tröster, Thomas id: '553' last_name: Tröster - first_name: Thorsten full_name: Marten, Thorsten id: '338' last_name: Marten orcid: 0009-0001-6433-7839 citation: ama: Chalicheemalapalli Jayasankar D, Stallmeister T, Lückenkötter JJS, Tröster T, Marten T.

However, traditional tooling methods often face challenges related to thermal management, design constraints, and material efficiency. This study examines the use of additive manufacturing (AM) in the development and optimization of injection molding tools to overcome these limitations. A novel prototype was fabricated using AM techniques, incorporating integrated cooling channels and optimized lattice structures to enhance thermal performance and simplify the manufacturing process. Experimental validation demonstrated the prototype’s effective integration into a vacuum-assisted resin transfer molding (VA-LRTM) system without requiring modifications to existing tooling setups. The results showed significant improvements in temperature regulation, reduced cycle times, and consistent mechanical properties of the molded components compared to conventional approaches. By reducing the number of tool components and eliminating the need for support structures during manufacturing, AM also minimized material waste and post-processing requirements. This research highlights the transformative potential of additive manufacturing in injection molding tool design, offering increased flexibility, cost efficiency, and enhanced functionality to meet the evolving demands of modern industrial applications. article_number: '571' article_type: original author: - first_name: Deviprasad full_name: Chalicheemalapalli Jayasankar, Deviprasad id: '49504' last_name: Chalicheemalapalli Jayasankar orcid: https://orcid.org/ 0000-0002-3446-2444 - first_name: Thomas full_name: Tröster, Thomas id: '553' last_name: Tröster - first_name: Thorsten full_name: Marten, Thorsten id: '338' last_name: Marten orcid: 0009-0001-6433-7839 citation: ama: 'Chalicheemalapalli Jayasankar D, Tröster T, Marten T.

Small and medium-sized enterprises often struggle to implement future-oriented digital business models. The aim is to develop decision support to help companies plan ahead and assess their value proposition, with a focus on foresighted planning. Based on literature research, expert interviews and the analysis of existing solutions, an understanding of “sustainable value” and requirements of decision support are defined. Decision support is implemented in a software. The main contribution is the setup of functions and content such as a list of influence factors, analysing influences and evaluating ideas, control questions and support for the implementation of digital business models. Validation through expert interviews and workshops in mechanical and plant engineering shows that the software supports enterprises in foresighted planning of value proposition and the selection of a concept for digital business models. It makes them robust towards the variety of future scenarios. author: - first_name: Iris full_name: Gräßler, Iris id: '47565' last_name: Gräßler orcid: 0000-0001-5765-971X - first_name: Alena Marie full_name: Tusek, Alena Marie id: '59370' last_name: Tusek citation: ama: 'Gräßler I, Tusek AM.
