Abstract
This research aims to reverse engineer the body pattern of a hydrant pump using sand-cement molds and aluminum (Al) material. It investigates the effect of the casting process on the mechanical properties of the resulting hydrant pump body pattern, as well as the extent to which the machining process performed after casting influences the final quality of the hydrant pump body pattern made from aluminum material. The casting results showed defects such as trapped gas and rough surfaces, which were improved through machining processes, including smoothing, filling, and painting. Tensile testing (ASTM E8) yielded a maximum load of 101.538 MPa and a strain of 3.25%, in accordance with the standards of 90 MPa and a strain of 3–5%. Impact testing (ASTM E23) indicated a value of 0.3625 J/mm², compared to the standard of 0.1179 J/mm², signifying good material toughness. Chemical composition testing (ASTM E415) revealed an aluminum content of 85.08% and silicon content of 9.545%, which enhances the material's strength. The aluminum material is classified as number 4030. Based on the measurement results, it is concluded that the mold pattern design should be made larger to anticipate machining, as the machining percentage is high for the hydrant pump body pattern measuring 430.50 mm, while the product volume is 422.40 mm. The average machining percentage for the cast hydrant body is 1.50% of the hydrant body pattern design.
