Choose Inspection by the Defect You Need to Detect

Different inspection tasks require different technologies. Define the target defect first, then evaluate the system using representative products, packaging and line conditions. ZONESUN can help configure individual inspection stations or combinations for your packaging process.

Metal & Foreign Objects

Evaluate a metal detector or X-ray system for your target contaminant and package. Confirm detection performance with agreed test samples rather than assuming one technology detects every foreign material.

Explore ZS-MD60 X-ray Inspection →

Weight Verification & Sorting

Check package weight against defined limits or sort products into weight bands. Specify the complete package weight, required tolerance, dimensions, item spacing and production throughput.

Explore ZS-MD1010 Checkweigher →

Caps, Codes & Visible Defects

Evaluate camera-based checks for defined cap, code or visible bottle defects. Provide acceptable and defective samples so lighting, camera views and rejection rules can be assessed.

Explore ZS-MD3 Cap & OCR Inspection →

Bottle & Can Fill Levels

Evaluate visual or X-ray level inspection according to container transparency, packaging material and product properties. Define the acceptable fill-level range and required production speed.

Explore ZS-FA3012 Level Inspection →

Foil Seal Inspection

Evaluate inspection for your foil, closure and sealing process. Define whether the task concerns foil presence or a specified thermal indication, and agree on the seal defects to be tested.

Explore ZS-MD50 Thermal Inspection →

Container Vacuum Inspection

Evaluate online vacuum detection for compatible bottles and cans. Confirm closure construction, process conditions and acceptance criteria. A vacuum check is not a universal leak test.

Configure Inspection Around Your Production Line

Share the following information to define an inspection station, rejection method and integration scope.

  • Product & Package Contents, packaging material, dimensions and weight.
  • Target Defect Defect examples, test pieces and acceptance limits.
  • Production Speed Products per minute, conveyor speed and item spacing.
  • Conveyor Layout Height, width, direction and available installation space.
  • Reject Handling Reject mechanism, collection space and line-stop requirements.
  • Testing & Records Sample trials, result records and control-system connections.

Additional quality-control equipment: This collection also includes optical color sorters and a flip-cap life tester. Color sorting addresses bulk-product separation; cap life testing evaluates repeated opening and closing. These serve different tasks from inspecting finished packages inline.

Validate your application: Confirm detection limits, false-reject criteria and rejection performance using representative samples under the intended operating conditions. Capabilities depend on the selected equipment and configuration.

Inspection Selection Questions

Can one machine inspect weight, caps and foreign objects?

These tasks may require separate inspection stations or a specifically configured combination system. Define each requirement and confirm which functions the proposed equipment includes.

Does foil seal inspection prove that a package is leak-free?

A foil-presence or thermal check does not by itself prove complete leak tightness. Define seal defects and leak acceptance criteria separately, then select and validate the appropriate test method.

Can defective products be removed automatically?

Automatic rejection depends on the selected model and line configuration. Confirm product stability, spacing, reject timing, collection arrangements and the required response to a failed rejection.

Can inspection equipment connect to an existing line?

Integration should be evaluated against conveyor dimensions, production speed, product transfer, available space, utilities and control interfaces. Share a line drawing or video with your inquiry.
