An estimation system for estimating an injection-molding related cost
comprises an input unit, storage, a data processing unit, and an output
unit. The storage stores a mold estimation function for each of cost
items of a mold used to produce a molded product, and a mold estimation
reference value table for recording mold estimation reference values in
association with prescribed conditions. The data processing unit acquires
a fabrication condition of the molded product through the input unit,
reads the mold estimation function and one of the mold estimation
reference values from the storage corresponding to the fabrication
condition, and estimates a cost of the mold based on the mold estimation
function and the selected mold estimation reference value. The output
unit outputs a mold cost estimation result made by the data processing
unit.
