Pengaruh variasi ketebalan saluran dan temperatur tuang terhadap fluiditas dan porositas hasil pengecoran kuningan pada pengecoran evaporatif

The development of foundry technology continues to grow along with the increasingly complex needs for making products based on art and culture, one which is sclupture. Evaporative casting non-permanent patterns made polystyrene foam, advantage precision results in shapes. purpose this study was determine how variations pouring channel temperature affect fluidity porosity brass castings evaporative casting. Casting carried out thicknesses 1.5, 2, 3, 4, 5 mm at temperatures 900°C, 950°C, 1000°C using a composition Cu60% Zn40%. highest found pattern density 0.012 gr/cm3 flow length 150 mm, while lowest obtained 0.016 900°C 13 mm. scanning electron microscope (SEM) observations can be observed spesimens foam high temperature, an increase formed.
