Abstract

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.

Abstract

PT X produces bottles using extrusion blow molding machines that produce EL 125-ml bottles of polypropylene borealis material. In the production process, there is a process of cutting the remaining material at the mouth of the bottle, called abfal. The separation of the abfal from the bottle mouth is still done manually by the operator before the product enters the quality control camera area. This research is experimental, comparing the pressure parameters and blow pin time with the thickness of the abfal mouth using an optical profile projector measuring instrument. In the variation of pressure parameters to the thickness of the abfal mouth, the thinnest occurred in the variation of blow pin pressure fast 80 kg/cm² and blow pin pressure slow 70 kg/cm² by 0.085 mm, and the size of the thickest abfal mouth occurred in the variation of blow pin pressure fast 60 kg/cm² and blow pin pressure slow 50 kg/cm² by 0.195 mm. In the variation of time parameters to the thickness of the abfal mouth, the thinnest occurred at a blow pin time of 1.4s by 0.085 mm, and the size of the thickest abfal mouth occurred at a blow pin time of 1.2s amounting to 0.195 mm. The results showed that the thickness of the abfal mouth is thinner if the pressure and time of the blow pin are given greater, and vice versa, if the pressure and time of the blow pin are given smaller, then the size of the abfal mouth is thicker

Abstract

The brake block in the railway bogie system is an important component in supporting the operational safety of trains, so it needs to be inspected to determine its performance and service life. A simulation-based study was conducted to predict the wear rate of railway brake block with oriented braking force (F = 25.66 kN - 29.54 kN) and different material types, namely grey cast iron with hardness 170 HBN and metallic composite with hardness 90 HRR. The method of the study was carried out by Finite Element Analysis (FEA) simulation and calculating the wear rate with the Archard wear equation to measure the comparison of the amount of wear volume that occurs on the two materials. The results of the braking ability calculation can be concluded that the different types of brake block materials can affect the ability to decelerate during the deceleration process, causing differences in stopping mileage according to the type of material, such as gray cast iron (μ = 0.30) which has an average mileage of 15 metres and metallic composite (μ = 0.21) has an average mileage of 66 metres. The wear simulation results obtained are that the grey cast iron brake block has an average wear rate of 2,8285e-08 /s which is greater than the metallic composite which is only 1,5391e-08 /s. With this data, it can be concluded that oriented to the braking force load, the metallic composite brake block material has the advantage of a longer service life than grey cast iron.
