Abstract

Maintenance department often has problems with process transfer dies. One of the problems currently being faced is scrap jams that disrupt the production process. The accumulation of scrap results in damage to the product being processed. Therefore, the process must be stopped for 15 minutes to clean the scrap. This research aims to overcome the problem of stuck scrap on LHD dash panel dies by modifying the dies. Identification of causes and effects using a fishbone diagram resulted in the fact that the cause of the scrap jam was the method factor, namely the scrap sutter angle which was too sloping at 80 so that the scrap did not run smoothly and caused buildup in the process area. Dies modification is carried out by adding components to the base plate so that the scrap cutter angle increases. The modification process begins with measuring the components to be modified, followed by creating component designs using CAD software, assembly simulation, docking, machining and assembly processes. After assembly, the scrap sutter angle is measured. There is a change in the scrap sutter angle from 80to 280. The change in the scrap sutter angle makes the scrap material flow smoothly so that no scrap accumulates. From the calculation results it was found that the benefit after improvement was 31,040,000 rupiah per year.

Abstract

The automotive industry in Indonesia is one of the priority industrial sectors that is developing quite rapidly. The automotive component production process in industry generally includes the molding process, welding process, assembly process, and automotive component quality control process. During the welding process,the ST-03 electroda used by PT ST-03 electroda repairs were carried out using a CNC Milling machine. The electroda repair process is carried out one by one with a total time of 120 minutes or 2 hours per day. The large amount of time required for the repair process makes loading parts hampered. Therefore, a jig machining design was carried out to speed up the electroda repair process. The ST-03 jig machining material used is SS 400 iron. The product design was carried out using CAD software and then simulated using CAM. The simulation results show that the use of jig machining can reduce production time by 98%or 118 minutes. This is because in one set up you can repair 20 electrodas so that in 1 day you only need to do 3 set ups. The profit obtained from using the ST-03 jig machining electroda is 166,500,000 rupiah per year.

Abstract

The redesign of the die design in the blank-pierce process for the RH/LH quarter panel extension reinforcement product was carried out using field observations to obtain actual data. The production process consists of five stages: blanking, piercing, restriking, bending and forming. Meanwhile, in the redesign process, the RH/LH quarter panel extension reinforcement product is evaluated in the blanking and piercing die processes. Cycle time analysis after the tool design has been redesigned shows the potential for increasing efficiency by reducing process time. MPP data is used as a guide for die design with relevant machine specifications, die size and materials. Machine pressure and tonnage calculations were carried out for the current die design and the revised version, showing significant improvements in production efficiency. The die redesign was carried out to increase output per stroke and to use more sophisticated automation processes. The results of this research show that improved die design can increase production efficiency and productivity by reducing the number of strokes required and properly adjusting machine capacity.

Abstract

Angular welding is a commonly utilized technique in the manufacturing industry, particularly in the construction of frame structures. The primary challenge in angular welding is ensuring the accuracy of the angles and the strength of the joints. At Polytechnic STMI Jakarta, the Jig & Fixture Production course aims to train students in using appropriate manufacturing techniques and tools, including welding jigs. The use of welding jigs can improve the precision, efficiency, and consistency of welding results, while also reducing the risk of human error. This study aims to design and analyze a welding jig for angular welding in the context of practical coursework at STMI Jakarta Polytechnic. The research methodology includes a literature review, jig design using CAD software, prototype development, and performance testing and analysis of the welding jig. The expected outcomes of the study are to enhance the quality and efficiency of the angular welding process. Additionally, the designed welding jig provides ease of use for students, thereby reducing errors caused by human factors.

Abstract

The bypass system in spin-on type oil filters plays a crucial role in maintaining engine cleanliness and performance by allowing oil to flow when excessive pressure occurs. A critical component of this system is endplate-B, which fulfills dual roles: providing structural support and functioning as an interface for oil passage during bypass operations. However, the relatively high material usage and cost associated with the current design of endplate-B pose challenges in manufacturing efficiency. The objective of this study is to minimize the material cost of endplate-B by optimizing its dimensional geometry without compromising its structural and functional performance. The research methodology encompasses dimensional redesign, structural analysis, and performance validation under simulated operating conditions. The findings indicate that strategic dimensional modifications can substantially reduce material usage while preserving mechanical strength and functional integrity. The implementation of this optimized design provides a cost-effective solution for the manufacturing of oil filters and contributes to broader efforts to improve production efficiency in the automotive component industry.
