Capability-based limits
We compare the missing-item weight against product, carton, leaflet and packaging variation to establish whether a dependable inspection window exists.
Finished-pack assurance
Carton checkweighers for missing-content and gross-weight control
Use in-line gross weight as a fast, non-destructive indicator of product completeness. From small pharmaceutical cartons to food, cosmetic and general-manufacturing packs, the system is configured around the detectable weight difference and the normal variation of every pack component.

System design
Determine what weight can prove before choosing the machine
Carton inspection depends on stable presentation and a measurable separation between normal good-pack variation and the missing or incorrect component.
Square product presentation
Side guides and controlled transfers keep cartons aligned and reduce the measurement disturbance caused by skewed entry or belt-edge contact.
Fast recipe selection
Stored formats can link target weight, limits, speed and reject timing to an approved product recipe.
Multi-technology verification
Barcode, print, label and vision checks can be added when identity, artwork or code quality cannot be established by weight.
Specification
Build a meaningful carton test
- Collect representative good packs from normal production
- Measure the full range of product and packaging variation
- Create known faults for each missing or incorrect component
- Confirm the smallest weight difference that must be detected
- Test at the real line pitch and orientation
- Define the action for ambiguous or consecutive rejects
- Decide which identity checks require barcode or vision technology
Line integration
One inspection point for weight, identity and print
Cartons are well suited to combined inspection. A barcode reader can confirm product identity, vision can verify label or printed code presence, and the checkweigher can assess gross weight. Results can feed a common reject decision and batch record, reducing the number of separate stations operators must supervise.

Combine weight with barcode, label and product verification
Weight-based completeness can work alongside barcode identity, artwork and printed-code inspection when each result remains traceable to the same carton.
Discuss integrated inspectionFrequently asked questions
Questions about cartons
These answers help establish what gross weight can prove, which faults need another technology and how performance should be accepted.
Can carton weight confirm every component is present?
Only when each missing or incorrect condition creates a detectable difference beyond normal good-pack variation. We recommend testing representative packs before fixing acceptance limits.
Can small pharmaceutical cartons be weighed dynamically?
Yes. Compact conveyors, close transfer gaps and controlled product pitch are used for lightweight cartons.
Can the checkweigher read a barcode too?
A barcode reader or vision system can be integrated into the inspection cell so identity and weight results contribute to one line decision.
Can reject events be recorded by batch?
Yes. The required batch fields, totals and export method should be agreed during specification.

Controlled, repeatable inspection
Pharmaceutical
Verify carton, bottle, device and kit weight without relying on periodic manual samples. A correctly engineered checkweigher may flag missing-content or component-count errors when the gross-weight difference is distinguishable, while supporting controlled recipes and secure reject handling.

Production data
Make weight inspection information useful beyond the machine HMI. From simple batch reports to line-level data exchange, we define the records, identifiers, retention and interfaces your production and quality teams actually need.

Reject systems
A weight result only protects production when the correct item is removed and its removal is confirmed. We select the reject principle around pack behaviour, throughput, available length and the way your quality team needs to contain and reconcile non-conforming product.
