Rancang Bangun Mesin Cetak Centrifugal Casting untuk Pembuatan Pipa Komposit Geopolimer

In the field of materials engineering, various types advanced have been found. This must also be accompanied by technological advances in production process. Centrifugal casting is an effective method for cylindrical objects such as pipes and pressure vessels. this research, a centrifugal machine designed made. The design process follows steps proposed Pahl Beitz, starting from requirements identification, concept design, layout analysis to fabrication method. Furthermore, was tested geopolymer composite pipes. From test results it stated that works well can cast pipe samples at speeds. sample cut into three-point bending specimen. obtained strength about 50 MPa (1500 rpm tube rotation) 36 (1200 rotation). Thus, concluded higher rotation, quality resulting product.
