Abstract

Waktu setup yang lama pada proses injection molding dapat menyebabkan downtime yang signifikan, mengurangi produktivitas, dan meningkatkan biaya produksi. Penelitian ini bertujuan untuk mengurangi waktu setup mold pada mesin berkapasitas 450 ton di PT MWT dengan menerapkan metode Single Minute Exchange of Dies (SMED). Metode ini diterapkan dengan mengidentifikasi dan mengonversi aktivitas internal menjadi eksternal serta menyederhanakan langkah-langkah aktivitas internal. Hasil penelitian menunjukkan bahwa waktu setup berhasil dikurangi dari 196 menit menjadi 156 menit, menghasilkan pengurangan waktu sebesar 20,4%. Selain itu, biaya produksi harian berkurang sebesar Rp333.333 atau sekitar 20,4% dari total biaya sebelum perbaikan. Peningkatan efisiensi waktu memungkinkan perusahaan untuk meningkatkan kapasitas produksinya tanpa menambah sumber daya. Penerapan metode SMED juga berdampak positif pada kualitas produk, dengan risiko produk cacat yang lebih rendah karena proses setup yang lebih cepat dan terstandardisasi. Penelitian ini menunjukkan bahwa metode SMED merupakan langkah efektif dalam meningkatkan efisiensi dan daya saing perusahaan di industri manufaktur.

Abstract

PT Ganding Toolsindo was faced with the problem of high automotive component die setup times. The main cause of the high setup time is the process of tightening and releasing the bolts which is done manually. The aim of this research is to design a tool for clamping dies which functions to help speed up the bolt installation process, so that the setup time for automotive component dies is reduced. The method used in this research is field observation followed by the die clamping design process. Design planning begins by drawing the object using CAD software based on the results of load calculations and determining the dimensions of the dies themselves and the press machine as well as selecting the dies material. Furthermore, proof was carried out that this die clamping design could reduce dies setup time using movement analysis with a pre-determined time study Measurement Time Method (MTM) method, where the results showed a time saving of 92.4%.

Abstract

Penerapan metode Single Minute Exchange of Dies (SMED) pada mesin press SEYI SN2-300 di PT Ganding Toolsindo bertujuan meningkatkan efisiensi pergantian dies dalam produksi. Tahapan program mencakup analisis proses, sosialisasi, pelatihan, pendampingan, serta evaluasi penerapan SMED. Implementasi menghadapi kendala pada identifikasi aktivitas internal dan eksternal serta adaptasi teknisi terhadap metode baru. Dengan analisis dan pelatihan intensif, beberapa aktivitas internal setup berhasil diubah menjadi eksternal, sehingga waktu setup turun menjadi 29,58 menit dari sebelumnya 35,73 menit. Selain mengurangi downtime, SMED mendukung sistem operasional yang lebih terstruktur, meningkatkan standar kerja, dan kualitas produksi. Evaluasi menunjukkan efektivitas SMED dapat terus ditingkatkan dengan alat bantu tambahan. Implementasi ini tidak hanya meningkatkan efisiensi, tetapi juga membangun budaya kerja disiplin dan berkelanjutan yang mendukung efisiensi waktu, pengurangan biaya, dan peningkatan kualitas produksi.

Abstract

In the automotive manufacturing industry, enhancing quality and productivity is crucial to meet customer expectations while ensuring safety, environmental sustainability, and energy efficiency. This study evaluates the collapse strength of automotive inner tubes following ISO 2941 standards, comparing lock seam design with SGCC material and resistance spot welding (RSW) applied to SECD material. The findings show that the lock seam process improves structural strength by approximately 20%, due to more uniform pressure distribution, leading to better stability. A key advantage of the lock seam is its spiral construction, which contrasts with RSW's localized spot welds, contributing to more consistent performance. Additionally, the lock seam process reduces production costs and minimizes environmental impact by using thinner, cost-effective SGCC material. It also enables faster production, enhancing delivery efficiency. The absence of welding fumes improves safety conditions and boosts operator morale, while contributing to a cleaner working environment. From a Product Lifecycle Management perspective, this study shows that the lock seam process optimizes design quality, production efficiency, and sustainability, aligning with the goals of Quality, Cost, Delivery, Safety, and Morale (QCDSM). These results support the adoption of lock seam technology for sustainable, efficient automotive manufacturing.

Abstract

The bypass system in spin-on type oil filters plays a crucial role in maintaining engine cleanliness and performance by allowing oil to flow when excessive pressure occurs. A critical component of this system is endplate-B, which fulfills dual roles: providing structural support and functioning as an interface for oil passage during bypass operations. However, the relatively high material usage and cost associated with the current design of endplate-B pose challenges in manufacturing efficiency. The objective of this study is to minimize the material cost of endplate-B by optimizing its dimensional geometry without compromising its structural and functional performance. The research methodology encompasses dimensional redesign, structural analysis, and performance validation under simulated operating conditions. The findings indicate that strategic dimensional modifications can substantially reduce material usage while preserving mechanical strength and functional integrity. The implementation of this optimized design provides a cost-effective solution for the manufacturing of oil filters and contributes to broader efforts to improve production efficiency in the automotive component industry.

Abstract

The bypass system in oil filters plays a crucial role in maintaining engine cleanliness and performance by allowing oil to flow through the filter when the pressure exceeds set limits. A critical component of this system is the coil spring that controls the bypass valve. In this study, an experimental approach was applied to reduce material cost while preserving performance. We redesigned the spring from four coils of 3.5 mm diameter to three coils of 3 mm diameter, using the same standard hard steel wire SW‑C. The redesigned springs were subjected to a standard impulse test of 250,000 cycles under 7 kgf/cm² pressure and a loading test with deflections from 1 to 10 mm at pressures up to 11 kgf. Results show that the new three‑coil SW‑C spring meets all performance criteria: impulse life and load‑deflection characteristics fall within standard tolerances. A direct comparison with the original design demonstrates negligible differences in functional behavior, confirming that material usage and costs can be reduced without sacrificing reliability. These findings offer valuable guidance for the cost‑efficient production of oil filter components in automotive engineering.
