Abstract

A mold is a tool for printing plastic products. The way it works is by installing the mold on a plastic injection machine, and then the machine does the injection process to put molten plastic material into the mold. In the mold, there is a cavity that matches the shape of the product to be made. Before a mold can be used, it must be designed and manufactured. ATK Polytechnic of Yogyakarta has one injection molding machine with several molds available. The available molds do not yet have a design based on various information, analysis, and calculations, so this research will make a mold design that is expected to be a guideline for making plastic injection molds and is expected to be able to analyze the needs for cavities, gates, ejector systems, cooling system. In this study, the design and calculation of mold construction, including the cavity, parting line, gate, ejector, cavity plate, core plate, runner, and cooling, were discussed. The purpose of this study is to determine how to design a basic mold construction with a two-mold plate system, with the resulting product being a tensile test specimen. The result of this tensile test specimen mold design is a mold base design drawing with a mold size of 350mm x 500mm x 255mm, the number of cavities being 4 cavities per mold, and the volume of the tensile test specimen mold being 33.0122 cm3.

Abstract

Extrusion blow molding is one of the most widely used manufacturing methods in the plastic industry for producing hollow containers, such as jerrycans, with demands for uniform wall thickness and efficient material usage. One of the key factors affecting product quality in this process is parison programming, as the parison thickness distribution determines the material distribution during expansion inside the mold. However, improper parison settings often result in uneven wall thickness distribution, which can reduce structural quality and increase material consumption. This study aims to analyze and optimize parison thickness settings in the extrusion blow molding process to achieve a more uniform wall thickness distribution in 5-liter jerrycans according to design specifications. The research method was conducted by setting the Scale Parison Thickness parameter to 10%, operating the machine according to Standard Operating Procedures (SOP), and testing the product wall thickness at five different areas: the handle, upper section, upper body, lower body, and bottom section. Each area was measured at ten points using a micrometer to obtain the average thickness values. The results showed that the average thicknesses at the handle, upper section, upper body, lower body, and bottom section were 0.60 mm, 0.62 mm, 0.74 mm, 0.90 mm, and 0.89 mm, respectively, with a product weight of 141.1 grams. The obtained thickness distribution was still not fully uniform, indicating that the parison programming settings require further refinement to produce a thinner body section and thicker handle and bottom sections in accordance with design standards. This study concludes that more precise optimization of parison programming parameters can improve thickness uniformity, material efficiency, and the structural quality of the product. Furthermore, the findings provide practical contributions to the plastic industry by improving process control, reducing the potential for product defects, and supporting sustainable production cost efficiency.

Abstract

Dengan pertumbuhan industri plastik yang semakin pesat tentunya sangat berpengaruh pada kebutuhan tenaga kerja industri. Pelatihan ini bertujuan untuk memberikan bekal keterampilan pembuatan produk plastik dengan menggunakan mesin extrusion blow molding kepada siswa dan siswi SMKN 2 Depok Sleman. Pelatihan dilakukan dengan metode sosialisasi dan praktik kepada 35 peserta siswa dan siswi SMKN 2 Depok Sleman. Evaluasi pelatihan dilakukan dengan metode angket menggunakan kuesioner. Hasil pelatihan menunjukkan bahwa peserta pelatihan mampu membuat produk plastik dengan menggunakan mesin extrusion blow molding. Peserta pelatihan menunjukkan antusiasme dan keaktifan yang tinggi selama kegiatan, serta memberikan umpan balik positif terkait pelaksanaan kegiatan. Hasil evaluasi keterserapan materi yang disampaikan selama pelatihan menunjukkan bahwa terjadi peningkatan nilai rerata dari 60,57 (pretest) menjadi 89,40 (posttest). Penilaian peserta terhadap berbagai aspek pelatihan juga menunjukkan hasil yang baik, dengan rata-rata nilai mencapai 4,45.

Abstract

Plastic waste is a material that is difficult to decompose in nature, making it harmful to the environment. Therefore, proper management is necessary, one of which is through a waste bank. The Dusun Rejosari, Srimartani, Piyungan, Bantul Waste Bank was established in 2024. This waste bank sorts different types of waste to be sold to collectors, aiming to improve the community's economy. However, a major challenge faced by the community is that plastic waste has not been processed optimally—it has only been sorted and sold to collectors. This community service activity (PKM) aims to address this issue by processing plastic waste into furniture products, thereby increasing its value. The activities include lectures, discussions, training, and mentoring on furniture-making techniques. The process of converting plastic waste into furniture chairs was carried out by four instructors and four assistant instructors, with 25 participants who are members of the Dusun Rejosari Waste Bank. As a result of this activity, participants gained knowledge and skills in processing plastic waste into furniture chairs. The community is expected to apply this training to enhance their income. Based on the evaluation results, the participant's comprehension of the material improved, as reflected in the increase in test scores from 70.43 (initial test) to 77.83 (final test).
