Patent ID: 7359886

Claim:
An estimation system for estimating an injection molding related cost, comprising: an input unit; a storage configured to store a mold estimation function for each of a plurality 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; a data processing unit configured to acquire that 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, wherein, the data processing unit is configured to retrieve the mold cost estimation function stored in the storage device to estimate processing cost of a variable part of the mold corresponding to the shape of the molded product, and the mold estimation function is a formula expressing a variable part processing time required to process the variable part of the mold, and the data processing unit is further configured to calculate the processing cost of the variable part of the mold by multiplying a fixed part average cost rate by the variable part processing time; and an output unit configured to output a mold cost estimation result made by the data processing unit.
