Applying light to find pinhole defects during ongoing production of a vast range of materials and products In recent years, the inspection process has become indispensable in all types of manufacturing. Hamamatsu optical pinhole inspection units find tiny pinhole defects to help manufacturers improve their product quality and reliability. Besides detecting pinhole defects, optical pinhole inspection units can also monitor drilling, boring and a host of other manufacturing processes. Problems caused by pinholes Liquid leaks Quality degradation Deformation and tears Corrosion Change in electrical...

Applications [Materials] Accommodates a wide range of materials and products Component and material examples Metal ex. · Stainless steel · Aluminum Paper and nonwoven fabric Semi-transparent materials · Milk cartons · Fabric Degree of difficulty in detecting pinholes in semi-transparent materials In optical pinhole inspection, the difficulty in detecting pinholes is vastly different between materials that let light pass through and those that don’t let light pass through. The words semi-transparent or translucent are used to indicate materials that let light pass through them. Yet there is a...

How to select [Flowchart for selecting an optimal unit] Does any item on the workpiece you want to measure meet any of the following conditions? [Does it contain any objects? Does the workpiece have bag shape contours?] Is the workpiece you want to measure a molded/formed product or a film-like material? molded / formed products Does light pass through the workpiece? What is the workpiece you want to measure? How small is the pinhole you want to measure? Does light pass through the workpiece? Is the pinhole size you want to measure 5 μm or less? Is the workpiece diameter 46 mm or less?

Detection principle G Pinhole judgment Hamamatsu optical pinhole inspection units allow setting the pinhole judgement threshold to any desired level. Inspection units judge light exceeding the threshold level as a pinhole. 1 Irradiates workpiece with light that is linearly shaped along the workpiece width. 2 Detects light scattering at pinhole or passing through workpiece. Workpiece [Light impervious material] Detecting light that passes through a pinhole No pinholes Light source unit Pinholes present Light source unit Light does not pass through the workpiece Detection unit Light passes through...
