Abstract

Proses pelipatan produk Tutup Botol Flip-Top biasanya dilakukan secara manual oleh operator. Produksitutup botol yang masal mengakibatkan siklus waktu pelipatan tutup, teknik, dan tekanan dalam menutuppada setiap Tutup botol Flip-Top menjadi tidak sama. Hal tersebut mengakibatkan kualitas dari produkflip-Top tidak seragam. Untuk itu diperlukan teknologi yang dapat mengatasi persoalanketidakseragaman hasil produksi pada produk flip-Top Cap tersebut. Perangkat in-mold closing adalahsolusi untuk mengatasi hal tersebut, yaitu perangkat tambahan yang dipasang pada cetakan injeksi untukmelakukan proses menutup produk tutup flip-Top secara otomatis saat produk masih didalam cetakan.Dengan menggunakan perangkat in-mold closing ini, waktu pelipatan produk dan tekanan saat pelipatanakan seragam, dengan demikian produk flip-Top hasil produksi akan memiliki kualitas yang seragam.Dari penelitiana ini dihasilkan rancangan mold dan perangkat in-mold closing untuk produk flip-top cap,jalur pelipatan produk pada perangkat in mold closing dan mengetahui cycle time setelah memakaiperangkat in mold closing. Tahapan penyelesaian dimulai dengan mengidentifikasi produk flip top cap ,mengonsep cetakan injeksi (mold), merancang jalur pelipatan, merancang konstruksi perangkat in moldclosing (IMC), melakukan analisis pelipatan produk, cycle time dan filling pada mold. Hasil analisissimulasi plastik flow, menunjukan hasil produk tidak mengalami cacat.

Abstract

PTFE tape is an additive material used in fastening processes, particularly on threads or screw joints. Its function is to provide sealing properties ensuring tightness and leak prevention at the bonded interface. One notable application is found at a gas cylinder maintenance facility operating under direct authorization from PT. Pertamina. This facility targets a daily operational capacity of handling thousands of Liquefied Petroleum Gas (LPG) cylinders. However, the seal tape installation on each valve is still performed manually, which presents several operational challenges in terms of efficiency and consistency. This research focuses on designing an automated device for seal tape application. The primary objective is to develop an automatic seal tape wrapper machine to optimize the sealing process in terms of speed and reliability. To achieve this, the design process follows the VDI 2206 methodology from the Verein Deutscher Ingenieure (Association of German Engineers) and utilizes the 3D modeling software SolidWorks. The final outcome is a PTFE tape machine capable of operating automatically with a cycle time of 5-6 seconds per valve, and a production capacity of up to 3,900 valves per day.

Abstract

Injection molding is a process by which plastic is heated until it softens to fill a closed mold and form a product. One of them is the benchtop injection molder, where the machine that was previously made at POLMAN had problems, namely the main frame structure and injection mechanism which was less sturdy during the injection process and the heating system which overheated. Based on these problems, a redesign and analysis was carried out on the existing benchtop injection molder machine. The design methodology used is VDI 2222, which is a technical concept design methodology suitable for product development. Heat Transfer Simulation on existing and latest designs using COMSOL Software with geometry, material, temperature, fluid inlet and outlet, and mesh parameters. The results obtained were uneven heat distribution to the middle of the existing barrel at a temperature of 4600K, while the new barrel had an even heat distribution to the middle at 4730K at the 10th second. The latest machine weighs 17.78 kg, dimensions 775 x 266 x 426 mm, barrel capacity 19 grams with an aluminum frame and tight band heater installation.

Abstract

POLMAN Bandung plaque is a thick product with a relief shape on the surface of the product. The product was originally made using sand casting technology, but now it needs to be developed using high-pressure die casting (HPDC) molding technology. This process was hampered by the absence of technical documentation, so development started from the available sand-casting products. This development was carried out in two stages, first product design, and second tool design. Based on the results of the research carried out, an optimal HPDC design has been produced according to the desired specifications. Product designs are obtained through 3D scanning technology to obtain appropriate geometric data. Then the data generated for mold design and the HPDC process includes a specific casting pressure of 400 bar; casting locking force of 1311 kN; piston diameter of 40 mm; 31.6% fill rate; piston movement (V(x)): first phase 0.497 ms-1 to 307 mm, second phase 2.08 ms-1 to 390 mm. The analysis process in the shot-sleeve simulation has produced the right data for the production process so that machine control is more precise, effective, and efficient.

Abstract

Indonesia is one of the countries with a high level of natural disaster vulnerability, so a good disaster mitigation process is needed. Amphibious Articulated All Terrain Vehicle (AAATV) is designed as one of the solutions to the difficulty of the mitigation process. Amphibious Articulated All Terrain Vehicle is a vehicle with special capabilities that are able to pass through various terrains. Amphibious Articulated All Terrain Vehicle consists of several systems, one of which is the propulsion system. In the Amphibious Articulated All Terrain Vehicle drive system, there is one sub-system, namely the transmission gearbox. This design process uses the VDI 2222 methodology. The design and validation process uses SOLIDWORKS and KISSsoft software. From the design results, it is found that the vehicle will use a Kubota V2203 type diesel engine with a power of 36.4 kW. The desired speed variation is achieved with values of 9.85 km/h, 19.34 km/h, 39.64 km/h, and 10.04 km/h. The design weight is 58.73 kg with dimensions of 346.1 mm x 260 x 347 mm
