Comparative Analysis of the use of Band Heaters and Infrared Heaters to Save Energy on Injection Molding Machines Type Borche Bi 320T

This study aims to compare the energy efficiency between the use of a heater band and an infrared heater on an injection molding machine type borche bi 320T. The injection molding machine is one of the main pieces of equipment in the manufacturing process of plastic products and plays an important role in shaping various consumer and industrial products. One of the critical aspects of the operation of injection molding machines is the significant energy consumption, especially related to heating. This study was conducted by measuring the energy consumption of both types of heaters under the same operational conditions. The results showed that the energy consumption of using a band heater was 46.9 kW, while the infrared heater was 38.9 kW, significantly more energy efficient by 17.1% compared to the band heater. Although the initial installation cost of the infrared heater is 87% higher than that of the band heater, the energy savings generated from the infrared heater can reduce operating costs by approximately $39 million per year. Higher energy efficiency means lower electricity costs and, thus, more efficient total production costs. The use of infrared heaters also has a positive impact on the environment. Reduced energy consumption means reduced greenhouse gas emissions from power generation. Therefore, besides the economic benefits, the use of infrared heaters is also in line with sustainability and environmentally friendly practices.

Enhancing Manufacturing Quality Through Statistical Process Control

In the manufacturing industry, statistical process control, often known as SPC, is a strong instrument that can improve both the quality of the product and the efficiency of the process. It comprises the utilization of statistical approaches for the purpose of monitoring and controlling a process in order to guarantee that it functions effectively and generates products that are of a consistently high grade. The statistical process control (SPC) method enables producers to identify variances, trends, and irregularities that may have an impact on product quality. This is accomplished by collecting and analyzing data from the production process. It is possible for manufacturers to discover and rectify problems in real time with the assistance of statistical process control (SPC), which is accomplished through the utilization of control charts, process capability analysis, and other statistical approaches. This results in decreased waste, greater productivity, and increased customer satisfaction. This article examines the fundamentals of statistical process control (SPC), as well as its application in manufacturing environments and the advantages it offers in terms of improving both product quality and process performance.

Changes in whey protein produced by different sterilization processes and lactose content: Effects on glycosylation degree and whey protein structure

In this study, the interaction patterns between whey protein and lactose were investigated after different ratios of whey protein and lactose (1:2.5; 1:3.0; 1:3.5; 1:4.0; 1:4.5) were treated with two typical sterilization process parameters in powdered products (68 °C, 20 min; 72 °C, 15 min) and two typical sterilization process parameters in liquid products (121 °C, 10 min and 121 °C, 15 min). It was found that the degree of the Maillard reaction of whey protein-lactose solution increased with increasing lactose content, increasing sterilization temperature, or extending sterilization time, which was accompanied by changes in the protein structure of whey protein. In addition, glycosylation accelerates the decrease in free sulfhydryl content, decreasing surface hydrophobicity and decreasing fluorescence intensity. These findings highlight the advantages of designing protein-carbohydrate formulations with a high ratio of whey protein-lactose (1:2.5) to meet the requirements of the product standards for preterm/low-birth-weight infant formulas. When comparing only the sterilization processes of powder and liquid products, the pasteurization process of powder products significantly reduced the degree of the Maillard reaction caused by heat treatment and reduced protein denaturation.

Steady-state and dynamic simulation of gas phase polyethylene process

Gas-phase polyethylene (PE) processes are among the most important methods for PE production. A deeper understanding of the process characteristics and dynamic behavior, such as properties of PE and reactor stability, holds substantial interest for both academic researchers and industries. In this study, both steady-state and dynamic models for a gas-phase polyethylene process are established as a simulation platform, which can be used to study a variety of operation tasks for commercial solution polyethylene processes, such as new product development, process control and real-time optimization. The copolymerization kinetic parameters are fitted by industrial data. Additionally, a multi-reactor series model is developed to characterize the temperature distribution within the fluidized bed reactor. The accuracy in predicting melt index and density of the polymer, and the dynamic behavior of the developed models are verified by real plant data. Moreover, the dynamic simulation platform is applied to compare four practical control schemes for reactor temperature by a series of simulation experiments, since temperature control is important in industrial production. The results reveal that all four schemes effectively track the setpoint temperature. However, only the demineralized water temperature cascade control demonstrates excellent performance in handling disturbances from both the recycle gas subsystem and the heat exchange subsystem.

Comparison of the hardness value and microstructure of Al6061 in horizontal centrifugal casting with and without mold cooling

The object of this research is the horizontal centrifugal casting process of the Al6061 alloy. Usually, cast products experience some casting defects, so the horizontal centrifugal casting process is applied to reduce the possibility of casting defects arising. In some casting processes, especially in the production of cylindrical specimens, casting defects such as porosity are encountered. Therefore, horizontal centrifugal casting was applied to overcome this problem. The test results show that the average hardness value for aluminum 6061 specimens resulting from centrifugal casting products with water cooling was 73.3 HRE, while the average hardness value for aluminum 6061 specimens resulting from centrifugal casting products without water cooling was 86.4 HRE. The microstructure results show that the grain size of centrifugal casting products with water cooling was 82.5 µm, whereas without water cooling it was 75 µm. Higher hardness values were obtained in specimens without mold cooling, this is because the conductivity in molds without cooling was higher compared to molds that experienced water cooling. The higher the heat conductivity of the mold, the faster the cooling process of the cast product. The casting process using the horizontal centrifugal method can be carried out to produce cylindrical spare parts

Effect of Different Concentration of CO2 Gas Injected into Fresh Cement Paste Along with the Addition of Superplasticizer on the Mechanical Properties of Cement

This paper focused on examining the impact of injecting varying concentrations of carbon dioxide (CO2) gas on the mechanical characteristics of both the fresh and hardened states of cement paste. This study also considered the influence of the presence or absence of polycarboxylate superplasticizer in cement mixture on these properties. Many researchers discovered the benefit of CO2 gas utilization in cement mixture to accelerate the early strength of cement or concrete hydration by its carbonation that form calcium carbonate (CaCO3). The application method is to directly inject CO2 gas in a curing chamber for air-curing of precast concrete. Alternatively, carbonated water is mixed with cement during concrete mixing. However, the use of CO2 gas does not significantly improve the 28-day strength of concrete. This study explores how to improve the carbonation impact on mechanical properties of cement paste and apply it to ground improvement. In this study, the method adopted is direct injection of CO2 gas during cement slurry mixing with different injection duration. The influence of CO2 in the presence of superplasticizer (SP) in cement slurry was also studied as SP is generally used for grouting. The results showed that the carbonation of cement paste with additional of superplasticizer significantly affect its flow, viscosity and bleeding properties. Unlike samples with SP addition, the samples without SP addition showed higher compressive strength after 28 days of curing up to certain CO2 injection time. For all CO2 gas injection time, smaller porosity rates were observed for 7-day cured samples with SP addition compared to those without SP addition. This is due to accelerated carbonation due to SP presence in cement mixture. From the results, the optimum of CO2 gas injection time for one liter mixture of cement paste to improve its compressive strength (up to 123% increase) have been discovered. It can be inferred that the addition of superplasticizer in cement slurry reduces the amount of CO32- ions and Ca2+ ions during carbonation process of cement hydration products, which are strongly related to the pH level in pore solution. These ions play a significant roles in determining the mechanical properties of cement slurry.

Experimental investigation of the multi-layer wetting behavior of electrode-separator-composites in lithium-ion batteries

The success of lithium-ion batteries and their application in electromobility is highly dependent on their scalable and cost-efficient manufacturing. Herein, electrolyte filling and wetting are time-consuming and quality-critical process steps, which have been, on the material level, primarily researched on an intra-material level for single-cell components while lacking overarching investigations for inter-material effects during wetting. This study demonstrates for the first time an experimental methodology designed to systematically quantify the interaction effects between different electrode-separator-composites during wetting by varying product components and process parameters. The investigation reveals a quantifiable interaction within a two- or three-layer material combination of anode, separator, and cathode, which can be discerned into distinct anode and cathode interaction effects, maintaining consistency across the product and parameter variations. Through the analysis of activation energy using the Arrhenius equation, the study observe a combinatorial relationship for modeling multi-layer wetting. Multi-layer wetting rates increase by 215 % compared to single material rates. Higher temperatures boost penetration rates due to lower viscosity, but reduce the interaction effect. These insights contribute to an application-orientated understanding of electrode-separator-composite wetting behavior and open up more possibilities for an optimized manufacturing process through expanding methodical exploration of strategies for counterbalancing poor wettability.

Role of PQBP1 in Pathogen Recognition-Impact on Innate Immunity.

The intrinsically disordered polyglutamine-binding protein 1 (PQBP1) has been linked to various cellular processes including transcription, alternative splicing, translation and innate immunity. Mutations in PQBP1 are causative for neurodevelopmental conditions collectively termed as the Renpenning syndrome spectrum. Intriguingly, cells of Renpenning syndrome patients exhibit a reduced innate immune response against human immunodeficiency virus 1 (HIV-1). PQBP1 is responsible for the initiation of a two-step recognition process of HIV-1 reverse-transcribed DNA products, ensuring a type 1 interferon response. Recent investigations revealed that PQBP1 also binds to the p17 protein of avian reovirus (ARV) and is affected by the ORF52 of Kaposi's sarcoma-associated herpesvirus (KSHV), possibly also playing a role in the innate immune response towards these RNA- and DNA-viruses. Moreover, PQBP1-mediated microglia activation in the context of tauopathies has been reported, highlighting the role of PQBP1 in sensing exogenous pathogenic species and innate immune response in the central nervous system. Its unstructured nature, the promiscuous binding of various proteins and its presence in various tissues indicate the versatile roles of PQBP1 in cellular regulation. Here, we systematically review the available data on the structure of PQBP1 and its cellular functions and interactome, as well as possible implications for innate immune responses and neurodegenerative disorders.

Coffee, popularly known as commodities, stimulates the farmer´s interest to innovate and to add value in products aiming for lucrative. One way to add value is through Short Food Supply Chains (SFSC), innovating and valorizing product processes, with basis on local culture. The main aim of this article was to analyze innovations developed by specialty coffee producers from Garça, Brazil, as they were introduced into SFSC and their impacts on environmentally sustainable production. This is a qualitative-quantitative research, with multiple case studies. Data was collected through semi-structured interview observation and documents, and analysis was carried out using Fisher's Exact Test. The main innovations verified for insertion in SFSC are the marketing skills, technical processes used in the harvesting, and machinery acquisitions for processing and packaging products without compromising the quality of the beverage. Although producers made a strenuous effort to promote the environmental sustainability, the statistical test has confirmed that there was no association between innovations and environmental sustainability. As practical implications, this paper seeks to contribute to farmers who want to change their production by selling specialty coffees through SFSC, demonstrating the innovations and their impacts on environmental sustainability, as well as public policymakers who wish to contribute to these farmers by promoting events that generate knowledge about innovations and sustainable environmental development.
