Abstract

This research aimed to create composites of carbon-phenol formaldehyde (PF) using carbonated rice husks as fillers. The composites showed electrical conductivity that increased with carbon content and decreased electrical resistance. The composites were evaluated for their physical, and electrical properties. The results showed that increasing PF content resulted in higher density but lower porosity, making the composites heavier. Specimens with 80% carbon weight and 20% PF weight produce an electrical conductivity of 0.055 [S/cm], while those with 70% carbon weight and 30% PF weight produce an electrical conductivity of 0.039 [S/cm]. Specimens with 60% carbon weight and 40% PF weight generate an electrical conductivity of 0.013 [S/cm].

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
