Increasing demand for foreign body inspection in raw material process

Due to the soaring prices of raw materials in recent years, the sources of procurement are forced to be diversified, which makes it more difficult to manage foreign body control for them. Introducing metal detection not only after product packaging but also in the raw material process has the following advantages.

  • Avoid risk of foreign body spreading and outflowing
  • Reduction of product waste loss
  • Achieve high detection performance without effect from the packaging material
  • Protection of downstream production equipment

Equipped with M6-h high sensitivity detection head

The M6-h head, which has been proven with high detection performance and stability on the actual production line, has been engineered and optimized for free fall inspection. False rejections have been significantly reduced by strengthening the resistance to external noise. Stable operation can be realized while the head is incorporated into existing production line.

Industry-Leading Detection Sensitivity

Rejection unit for powder / granule products

Prevent outflow of foreign bodies

The fail-safe design is contributing to it not only during normal operation but also when unexpected troubles occur.

  • Force the rejection gate to stand by on the reject side when the power is shut down or other abnormalities occurs.
  • Position monitoring of rejection gate
  • Automatic rejection operation check at start-up
  • Air pressure monitoring
Prevent Outflow of Foreign Bodies

Flexible Integration into the existing production line

Space Saving and Easy Wiring

By providing the detection head, indicator, and rejection unit in an independent and compact unit, the integration will be easy and space-saving. The detection head and the rejection unit can be connected with the indicator by a single cable.

Space Saving and Easy Wiring
