Abstract

PT.XYZ mengalami ketidak balancenya loding vs capacity pada produksi line assy caliper 2 dengan selisi produksi 13 pcs/jam selisi cycle time current terhadap take time adalah sebesar 2.1 detik data ini sesuai dengan laporan produksi line assy caliper 2 , Gap ini terjadi akibat proses clamping griper mesih dilakukan secara manual akibatnya banyak waktu Muda ( sia-sia ) pada proses tersebut. Sering terjadi part terjatuh , part susah dipasang dan dilepaskan sehingga berakibat proses jadi delay selama 2,1 detik laporan ini terlihat pada grafik monitoring problem line produksi assy caliper 2 . Dengan konsep melakukan penelitian dilapangan produksi langsung kemudian menganalisa kareteristik proses produksi diharapkan problem yang terjadi dapat dicarikan solusi untuk menghilangkan waktu MUDA ( Sia-sia ). Dari hasil penelitian ini membuktikan bahwa memodifikasi jig & fixture dengan pendekatan prinsip 6 Degree Of Freedom dapat menghilangkan gap produksi pada line assy calip er 2 sebesar 2,1 dtk atau 13 pcs /jam dengan cara merubah proses produksi manual menjadi Otomasi dan membuat jig & fixture pencekam benda kerja yang peneliti sebut Chuki-chuki Otomation. Hasilnya setelah dirubah system manual ke otomasi dengan menggunakan Chuki-Chuki pencekam proses loading dan unloading caliper di line assy caliper dapat dihilangkan sehinga bisa mengurangi waktu 1,5 dtk waktu loading dan unloading

Abstract

This research accelerates the production process with the aim of increasing productivity from Manufacturers engaged in the manufacture of automotive parts currently experiencing an increase in sales orders on the other hand facing problems in productivity due to cracked side dies in rim production to 1400 pcs. The cracking of the side die is due to thermal shock that occurs to accelerate the production process, as a result of which cracks occur in the side die. With the concept of conducting research in the field of direct production then analyzing the characteristics of mold materials, die characteristics, process characteristics, characteristics of finished products before and after changes by testing the results of the laboratory of measuring instruments and conducting trials of variations in machine setting parameters, variations in the production process and products produced. The experiment involved changing the standard temperature from 520 °C–545 °C to 532 °C–538 °C and reducing the immersion time from a minimum of 270–540 seconds to 332 seconds. It reduces the soaking time from 69 seconds to 46 seconds and the aging time from 190 seconds to 180 seconds, increasing the casting productivity from 194,870 Pcs/28 days to 213,311 Pcs/28 days from seven machines, thus meeting the customer's requirement of 200,000 Pcs/28 days without cracking side die. Durability testing on five product samples in accordance with TSD5605G standards confirms that the quality meets customer specifications. The results of this study prove that SKD6 matrial is much stronger than FCD550 against thermal shock. Keywords: thermal shock, die disc car wheel, manufacturing, automotive parts, casting productivity
