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.

Penelitian ini dilakukan berdasarkan hasil survei dan investigasi pada industri elektronik yang berlokasi di Bintan. Perusahaan tersebut bergerak pada bidang Design and Manufacture of Precision Engineering Plastic Components and Electronic Connectors. Dari hasil konsolidasi diperoleh bahwa salah satu aktivitas yang dilakukan yaitu melakukan proses maintenance dengan cara melakukan penggantian suku cadang Molding yang digunakan untuk menghasilkan komponen plastik maupun elektronik. Pada aktivitas produksi, suku cadang Molding tersebut secara prosedur pasti dilakukan pergantian setiap jumlah produksi tertentu atau bisa diperkirakan setiap bulannya terjadi pergantian suku cadang. Oleh karenanya menjaga kesediaan suku cadang menjadi hal yang urgen demi terlaksananya proses produksi dan terpenuhi target perusahaan. Suku cadang yang dimaksud selama ini dipesan dan dibuat dari negara Singapura sehingga perputaran, proses transfer maupun kajian teknologi tidak termanfaatkan oleh industri di Indonesia. Padahal nilai suku cadang yang diganti setiap bulannya sangat besar dengan perkiraan secara kasar memiliki nilai total milyaran rupiah. Berdasarkan hal tersebut diperlukan kajian yang berfokus untuk mendalami proses pembuatan suku cadang dari Molding sehingga industri tidak perlu mengimpor suku cadang dari negara luar.

A welding manipulator is a specialist apparatus engineered for welding extensive and elongated pipe plates on both interior and exterior surfaces, as well as in vertical and horizontal positions. During the assembly process, a challenge occurs when the platform is excessively distanced from the nozzle, complicating the operator's task with the welding manipulator. Brackets are an effective option to mitigate hazards and address issues throughout the cutting process. The aim of this research is to design and evaluate the safety of the bracket utilized for the platform component of the welding manipulator. The research utilizes Finite Element Analysis (FEA) to assess the simulated values of the safety factor and stress distribution. The findings demonstrate that the bracket design satisfies strength criteria, producing a maximum stress value of 98,327,504.00 N/mÂ². The recorded maximum displacement is 1.094 mm, and the maximum strain is 0.00022. The computed safety factor is 2.1, indicating that the design parameters surpass established safety criteria.

This study aims to determine the ideal heat input to remain within the constraints set in the preliminary Welding Procedure Specification (pWPS). Heat input greatly influences weld quality, mechanical properties, and residual stresses, yet accurate determination during Procedure Qualification Record (PQR) trials remains challenging. This research involved field data collection during PQR testing using two coupon specimens made of ASTM B564 UNS-N06625 and ASTM B444 UNS-N06625 Grade 1 materials, each with dimensions of 11.07 mm in thickness and 60.3 mm in diameter. The Gas Tungsten Arc Welding (GTAW) process was applied in the 6G position. The acceptable heat input ranges in the pWPS are: Root (1.0–2.5 kJ/mm), Hot (1.0–2.6), Filler (0.69–1.39), and Cap (0.6–1.1). In coupon test 1, two passes failed: Pass 3 (1.51) and Pass 5 (1.43). In coupon test 2, three passes exceeded limits: Pass 4 (1.64–1.97), Pass 5 (1.42–1.72), and Pass 8 (1.19). To ensure compliance, recommended heat input parameters were formulated. For the root pass, use 97–103 A, 9–10 V, over 4 min 40 sec (2.04–2.41 kJ/mm). For the hot pass, use 98–106 A, 9–10 V, for 4 min 48 sec (1.85–2.23). The filler pass should use 79–97 A, 9–10 V, for 3 min 39 sec (1.01–1.37), and the cap pass 81–90 A, 9–10 V, for 3 min 17 sec (0.64–0.79). These parameters aim to achieve high-quality welds in line with pWPS specifications.
