Nikka Densok

Nikka Densok is one of the first manufacturers of inspection machines in the pharmaceutical industry to use alternating current in leakage control technology. The Pinhole Inspectors are designed for non-destructive testing of a wide variety of pharmaceutical and food packages, including glass, plastic and flexible packaging, containing an electrically conductive solution. The high-voltage spark test method eliminates the risk of secondary contamination of the product and ensures product integrity by identifying small pinholes, microcracks and sealing defects that are not visible.

There are several methods commonly used in the pharmaceutical and food industries for the detection of pinholes, cracks and defective seals in various pharmaceutical and food packaging. These tests range from vacuum or pressure drop tests to immersing the product in a dye solution under pressure and visually inspecting the product for paint or more advanced vision systems to inspect the product for certain defects. Nikka Densok is one of the world leaders in High Voltage Leakage Control (HVLD) machines for both pinhole and crack inspection.
