Abstract:
The purpose of this research is to analyze how
the scrap material or metal scrap can be reused as a regular
material in a production process. The reused scrap material
is prepared to use in propeller shaft guard production. This
propeller shaft guard is used with the main function to
guard the propeller shaft in the car. Therefore, calculating
the total mass of the scrap material and propeller shaft
guard is needed to know the ratio of the usage of material,
the machine tonnage calculation for propeller shaft guard
production using reused scrap material, and the new design
for blanking material. The total machine tonnage for
producing propeller shaft guard using reused scrap material
is 260.09 T. The new design for the propeller shaft guard can
fit the reused scrap blanking material is created. The total
usage of scrap material increased from 49.46% to 79.69%
after the material was used in the propeller shaft guard
production. The comparison between the condition before
and after using reused scrap material as the propeller shaft
guard indicates the factors of the total amount of blanking
material, the total amount of dies, and dandori are described
in this research.
