Oct 21, 2023

Nikka Densok recently exhibited at ACHEMA 2022 in Frankfurt Germany. During the multi-day conference Nikka Densok presented their new HDI pinhole inspector machine for Blow-Fill-Seal (BFS) strips.The new machine does complete automatic entire body inspection using high voltage leak detection (HVLD) technology.

Here are some details on the new system:

Nikka Densok USA, a subsidiary of Nikka Densok LTD in Japan, specializes in CCIT using High Voltage Leak Detection (HVLD). Nikka Densok Pinhole Inspectors are designed for non-destructive testing of a wide variety of pharmaceutical and food packages including glass, plastic and flexible packaging that contain an electrically conductive solution. The high voltage spark test method eliminates the fear of secondary contamination to the product and ensures product seal integrity by identifying small pinholes, micro cracks, and seal imperfections that cannot visually be seen.

There are a variety of methods widely used within 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 decay tests, to submerging the entire container into a dye solution under pressure and visually inspecting the container for the presence of dye, or more advanced vision systems to inspect for certain defects in the container. There is no other system in the world that will be able to detect both holes and cracks as consistent as Nikka Densok’s High Voltage Leak Detection systems.
