“…As a major contributor to the world economy, China is the world's largest producer and consumer of coal and, naturally, the world's largest emitter of carbon [25][26][27][28]. Therefore, improving the efficiency of energy use and reducing carbon emissions are necessary parts of our production and processing [29][30][31]. During the process of forming large-scale automotive instrument glass, the heating apparatus requires electrical energy, the main source of which is coal used for electricity generation.…”

“…However, in terms of sustainable manufacturing, processing large-size glass using the GMP method has several disadvantages, including low efficiency, uneven heating, large temperature gradients, and low optical properties of the glass components after processing. By combining advanced technologies, such as ultrasonic-assisted GMP [31][32][33] and laser-assisted GMP [18,34,35], the efficiency and effectiveness of the hot bending process can be improved, resulting in higher-quality and more accurate glass elements. In a follow-up study, we will conduct further research on these two auxiliary processing technologies.…”

In recent years, as an important functional material, glass has been widely used in architecture, electronics, optics, and other fields. As an emerging glass processing technology, the glass molding process (GMP) has received widespread attention and research in recent years. In this paper, we study the modeling and analysis of different heat transfer strategies for the energy efficiency of large-sized automotive instrument glass. The heat transfer model of the metal heating plate–conducting plate mold is established, the thermal energy efficiency in the forming process of large automobile glass is analyzed, and the energy efficiency of the mold in the heating stage is compared. The energy consumption per piece generated by the GMP heating device is reduced from 4865.2 to 4668.5 kJ, a reduction of 4.04%. By optimizing the heat flow density, the energy consumption per piece generated by the GMP heating device was reduced from 4865.2 to 4625.5 kJ, a reduction of 4.92%, meeting the sustainable manufacturing requirements.

Intensification of ultrasonic processes for diversified applications, including environmental remediation, extractions, food processes, and synthesis of materials, has received attention from the scientific community and industry. The mechanistic pathways involved in intensification of ultrasonic processes that include the ultrasonic generation of cavitation bubbles, radical formation upon their collapse, and the possibility of fine-tuning operating parameters for specific applications are all well documented in the literature. However, the scale-up of ultrasonic processes with large-scale sonochemical reactors for industrial applications remains a challenge. In this context, this review provides a complete overview of the current understanding of the role of operating parameters and reactor configuration on the sonochemical processes. Experimental and theoretical techniques to characterize the intensity and distribution of cavitation activity within sonoreactors are compared. Classes of laboratory and large-scale sonoreactors are reviewed, highlighting recent advances in batch and flow-through reactors. Finally, examples of large-scale sonoprocessing applications have been reviewed, discussing the major scale-up and sustainability challenges.

“…Therefore, it is very necessary to use different meshing methods and choose different element types for different components. Besides, the experimental results to verify the simulation results are not published in detail and clearly [5,6,25,[30][31][32][33][34] In this paper, a full finite element model is proposed. Accordingly, elements C3D8E and C3D20RE are used for PZT rings, and elements C3D8 and C3D20R are used for other parts of the model.…”

In this study, a new finite element model for ultrasonic welding equipment is proposed. This help to solve remaining issues such as element type selection for the numerical model, mesh size, and how to determine the parameters of piezoelectric materials. The obtained results clearly show the influence of element type and mesh size on resonance frequency and amplitude. Specifically, with a mesh size of 2 mm, it was concluded to be suitable for the model. For the C3D8 element (C3D8E), the computation time is reduced by 0.25 times compared to the C3D20R element (C3D20RE). After that, an experimental processing procedure is performed to evaluate the numerical simulation results. Specifically, the handling of signal noise when measuring a very small displacement at high frequencies of an ultrasonic vibrating device. Based on the confirmed finite element model, this model is extended to evaluate the influence of the load on the amplitude and resonant frequency of the ultrasonic welding system. The results show that when the load increases, the amplitude decreases while the resonant frequency increases. The results of this study can be applied to the design of ultrasonic vibration systems.
