PERANCANGAN DAN PEMBUATAN GATING SYSTEM PADA PRODUK CLAMP SADDLE DENGAN PROSES PENGECORAN LOGAM SAND CASTING

Abstract – PT. Aneka Adhilogam Karya is a national private company engaged in the sand-casting industry supplying its products to the Perusahaan Daerah Air Minum (PDAM) Indonesia. One of the products of piping supporting components manufactured is Clamp Saddle. Many of these products still have casting defects, such as gas porosity and shrinkage. Gating system is one of the most crucial factors to determine the quality of cast products. It is necessary to design a gating system for Clamp Saddle products. Then the casting simulation using ProCast 2018 needs to be done to get an optimal design and detect the presence of defect shrinkage or gas porosity. Furthermore, the sand casting process is carried out, and radiographic testing is carried out to detect defects in the inside of the Clamp Saddle product. The results of the study obtained agating system design with a pattern size of 400 mm x 335 mm then analyzed defects using ProCast 2018 on the variable total shrinkage porosity and air entrainment so that optimal results were obtained. Clamp Saddle product results from sand casting experiments were tested using radiography test(RT) to detect shrinkage or gas porosity and found some gas porosity but were still tolerable because of their small size of about 1 mm then they were few in number and were not gathered togethe

RANCANG BANGUN MESIN SANDER 3IN1 (DISC, BELT, SPINDLE)

The development of the metal industry cannot be separated from the utilization of supporting tools. The function of the supporting tools is to support processing time and improve product quality. In the process of making casting products, there is pattern making, namely the stages of making a replica of the product to be produced. Currently, the pattern-making process is still done manually and using conventional tools. It can take a lot of time and often the result of the pattern doesn't meet tolerance requirements. Constantly changing pattern geometry requires several sander machines to support the process, such as a disc sander to form a flat surface geometry, a spindle sander to form aradius surface geometry, and a belt sander to form the surface of objects that have a large surface area. Therefore, a combination sander machine is needed. This study uses the Ulrich method. The stages in the Ulrich method are identification of needs, determining the design concept based on the company's needs, determining the selected design, then doing the manufacturing process and testing the tool. Based on the design, design concept number 2 was chosen to actualize a product. In testing this machine is able to carry out the process of sanding pieces of wood for the bearing housing pump pattern for 38 minutes 44 seconds with a total budget of Rp. 5,454,000,-
