Abstract

In the oil and gas industry, manufacturing processes covered a variety of fields including pipe fittings production. Generally, this process involves a press machine utilized as a shape forming using punch-dies sets as mold profiles. The common problem found with the dies is the dimension of dies is not ergonomics to be handled manually by operators. Additionally, the support of dies tends to experience buckling upon receiving a pressure load of 15 MPa. Hence, alternative and practical designs are required, which have low deflection values and high fatigue resistance rates. Additionally, the designs are expected to be safe and economical. In this study, two alternative designs of punch-dies support are proposed. Subsequently, the FEA simulation was carried out for pipe fittings of 8 inches with ASME B16.9 standard size for WF Beam A36 Steel to compare the two proposed designs. The results show that alternative design 2 has a lower deflection value of 0.181 mm, a higher Factor of Safety of 3.21, and a higher cycle time of 358569 cycles than alternative design 1. Nevertheless, alternative design 2 has a higher production cost of 220 USD compared to alternative design 2. Therefore, this study shows that alternative design 2 has better performance while alternative design 1 is more economical.

Abstract

The use of plastic is often found in human life. Therefore, many manufacturing companies are competing to increase the production and quality of their plastic products. One way to increase production is to redesign a Mold base so that the Mold has a larger production capacity than before. The increase in product demand from consumers, which was initially 65,000 pcs/month to 95,000 pcs/month, is also the background for conducting this research. The purpose of this study is to redesign the soft tool using the old Mold base. The design uses Siemens UG NX 5 software. The Mold used is a two-plate Mold. The manufacture of the core cavity uses NAK 80 steel and plastic raw material in the form of Polycarbonate (PC). At the end of the study, a simulation was carried out using the Moldex 3D Flow Mold software to see the cycle time of the old and new Mold injection processes. From the results of this study, production capacity increased from 67,804 pcs/month to 118,536 pcs/month resulting in twice as many products as the old Mold design, with an increase in cycle time of 14.37% longer than the old Mold design also ensuring the quality of the product is maintained.

Abstract

Dalam fabrikasi logam, plasma cutting sangat penting karena menawarkan hasil potongan yang presisi, efisien dan fleksibel. Salah satu parameter kritis dalam plasma cutting yaitu cutting speed. Tujuan penelitian ini yaitu membandingkan kualitas hasil potong (cut quality) pada material mild steel dengan ketebalan 8 mm. Variasi cutting speed yang diteliti meliputi 3000 mm/min, 4000 mm/min, 5000 mm/min, dan 6000 mm/min. Pengamatan cut quality dilakukan secara visual dan pengukuran kedalaman hasil potongan menggunakan vernier caliper. Hasil pengamatan menunjukkan bahwa pada parameter cutting speed 3000 mm/min menghasilkan cut quality terbaik. Pada variasi cutting speed yang rendah menghasilkan cut quality yang baik karena plasma memiliki waktu yang cukup untuk penetrasi dan memotong material dengan bersih.

Abstract

Welding using a welding carriage is carried out to get better results compared to manual welding. The purpose of this study was to determine the effect of the welding angle variation on the Weld Bead size. In this study, the welding method used is GMAW (Gas Metal Arc Welding) using S550MC steel plate material using a voltage of 30.0 V and Wire Speed 8.0 m/s. Testing is carried out using several tools to measure the results of welding (weld bead), namely welding gauge and steel crossbar. This study was conducted by comparing the results of welding (weld beads) from different welding angles, namely 45º, 60º, and 90º angles. Measurement of angular variations in this test uses an inclinometer. The comparison results are seen based on the height and width of the weld bead, while for acceptance criteria using the 1e0099 welding general requirement standard with the condition of welding width of a maximum of 13 mm and a mechanical welding height of 2 mm. Based on the test results, welding at a 90° angle variation produces a weld bead that meets the acceptance criteria. In welding using an angle of 60 ° and 45 ° produces a weld bead that does not meet the acceptance criteria. From the experimental results it was found that the smaller the welding angle the size of the weld bead became wider
