Quality control system (iii-system) of molded products

摘要

The molding industry has adopted the overseas production method to make profits at molding plants at low personnel costs. In addition, various efforts have been made including change into high value-added products, stock optimization, minimum manning and running cost reduction by the use of electric injection molding machines. Of these efforts, especially, quality control (reduction of defect rate and decrease of inspection processes) and more efficient production (stock optimization and slash of indirect personnel cost) have been the important activities. As an information system that can be used for these activities, an IT-based system (iii-System) for molding plants has been developed and sold. The iii-System is capable of centralized management of up to 120 injection-molding machines at a molding plant. Its major features are: 1) View mold shop floor. The conditions of a molding plant can be monitored in real time from an office or a remote place by interconnecting molding machines via LAN. This function can display the conditions of molding machines in different colors to ensure the availability and newest information (quantity of production and cycle time) of each machine to be seen at a glance. 2) View molding quality. The items of checking the quality of molded products can be recorded in each of 4.5 million shots (molding cycles), so that this quality information and the history of alarms or setting changes at each molding machine can be monitored at the time axis of 24 hours.
