Recently, the production amount of automobile parts is gradually increasing as the market grows and plenty of parts are substituted by plastic products for efficient energy consumption. Thus, systematic control of mass production and management on plastic products is inevitable. Plastic products for the car are manufactured by injection molding process because of the attributes of plastic materials. During injection molding process, defective products can be broken out by internal or external environment change. Currently, most of inspections for the defective products are performed by visual inspection. The authors developed an automatic inspection system that can detect the defects of plastic product using vision system. The authors also developed image processing algorithm in automatic inspection system to detect various type of defects and scratch.
