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.
