35.5.4 Mold Data
Mold data are prepared in a database not in an e-catalogue because a mold has no
behavior. The following are described in the mold data.
• mold ID
• molded part ID
• mold size (length, width, height)
• capacity of cavity
• current temperature of mold
• mold set-up time
• pre-heating temperature
• pre-heating time
• cooling time, etc.
35.5.5 Trial Experiment
Trial implementation of the construction system of a digital eco-factory for injection
molding is underway. The e-catalogue creation system is implemented in parallel.
In the e-catalogue creation system, the abovementioned equipment templates are
installed already. An equipment item is created by filling up the parameters of the
corresponding template with concrete values, calculation formula of electric energy
consumption, etc. At the time when a virtual production line is constructed for simulation, some of parameters of the template are retained as variables. Their values are
provided from production scenarios, operation data and/or product data. Equipment
items in e-catalogues can be provided by equipment vendors, and also by production
engineers using practical data from their factory.
A virtual injection molding line is constructed as a multi-agent system of equipment agents generated from the selected equipment items in the above e-catalogue.
This virtual injection molding line is a core of the digital eco-factory for injection
molding. Simulation using this digital eco-factory for injection molding will provide
time series changes of electrical energy consumption from various views such as
an equipment level, a production line level and a factory level. This trial digital
eco-factory for injection molding is structured on a free multi-agent programmable
modeling environment “NetLogo” [15]. Figure 35.12 shows a part of screen shot of
the simulation execution example using the generated virtual injection molding line.
Changes of electric energy consumption for the injection molding machine and the
molding extraction robot are shown. This screen shot was taken when one process
cycle finished.
