Abstract

A series of predictable preventive activities to overcome machine failure during operation is very important because it produces good and stable spare parts. This research was carried out with the aim of preventing machine damage due to short circuits that occur in injection molding machines used for the sudden production of automotive component spare parts. The research was carried out using the Mean Time Between Failure (MTBF) and Mean Time To Repair (MTTR) approaches to calculate the time between the machine breaking down and the time it was repaired. The MTBF calculation results in this research were 72.9 hours or less than 4 days the engine would experience damage or every 72.9 hours the engine would experience damage again. The MTTR value obtained is 2 hours, where in 2 hours the work to overcome the damage can be done.

Abstract

The development of production demands in the automotive industry has resulted in an increase in the need for various shapes and types of metal materials. Components used in automotive industrial production require the strength and durability of metal materials. The products produced in this sector are very diverse, including engine components, vehicle body parts and various vehicle accessories. To be able to meet customer demands for quality and efficiency, adequate production process support tools are needed, of course, such as dies. This tool is very suitable for making products from sheet metal with the same shape and in large quantities in a relatively short time. However, in making printing equipment (Dies) it does not require operation, it requires precise calculations so that accurate process results will be obtained, especially in calculations and clearance accuracy. Efforts to improve quality and efficiency in the product manufacturing process, for this reason, an analysis and improvement of the clearance of the cut results on SPC440 material with a thickness of 1 mm for the Member Floor Side Inner Lh product was carried out. The results of the improvement in the clearance of the part were able to optimize the clearance value from 0.06mm to 0.075mm

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

This study aims to improve the efficiency of tofu production at Haji Ripit tofu factory through the application of Lean Manufacturing principles. The analysis was conducted using the Value Stream Mapping (VSM) method to identify and overcome time waste in the production process. The results showed the main problems, namely waste waiting and waste motion. Waste waiting was identified in the process of moving the stew to the filter, while waste motion was caused by the inefficient arrangement of the filter. To overcome the waste waiting, a modification was made to the boiling furnace by adding a hole for the output of the stew. This change successfully reduced the cycle time of the pouring process from 2000 seconds to 400 seconds, with a cycle time difference of 1600 seconds. In addition, to address waste motion, a re-layout was proposed by unifying the workbenches in the molding, cutting, and packaging processes. The results of the re-layout proved the reduction of movement time from molding to cutting process from 10 seconds to none. This research makes an important contribution in the context of improving efficiency and productivity in tofu factories, and the results can serve as a reference for similar industries in improving their operational performance through the implementation of Lean Manufacturing.

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.
