Cost modeling and cost assessment for a die casting process

Abstract

The work of this report provides a cost-based assessment and characterization of the

die casting for manufacturing. This process has potential to be a low-cost and efficient

manufacturing technology. Die casting can produce more complex shapes with closer

tolerances, thinner walls and lower manufacturing costs. In order to better understand

the cost effectiveness of the die casting process and the economic consequences on

die casting process, this report was generated. A manufacturing process which is

based on LCECA and PBCM was developed. By using this method the cost

assessment for a die casting process was conducted. It can be seen that the

manufacturing cost of a die casting is higher or lower than that of other manufacturing

processes. Cycle time, number of cavities, tool life and material scrap rate were

identified for the die casting process. Their effects on the total unit cost were analyzed

through real project cases. The results show that the die casting process which is

competitive manufacturing process has a cost reduction potential. This report

summarizes the studying results.
