Check Weighers
Checkweighers are automated weighing machines integrated into packaging lines to verify that every finished product meets the specified weight requirements before dispatch. Alpha Pack offers both dynamic (in-motion) and static checkweigher systems. Dynamic checkweighers verify product weight on a moving conveyor at high speed — ideal for continuous automated lines up to 120 pcs/min with automatic rejection of underweight or overweight products. Static checkweighers are used for larger or heavier items where the product is stationary during weighing — suitable for bulk commodities and heavy packaging. Both types integrate seamlessly with filling, sealing, and labelling equipment and provide real-time production data for quality control and compliance.

Engineering Advantages
Built for Demanding Production Lines
High-Speed Dynamic Weighing
Dynamic checkweighers verify product weight on a moving conveyor at speeds up to 120 pcs/min enabling continuous, non-stop quality verification without slowing production.
Automatic Rejection Device
Non-compliant products are automatically rejected from the line ensuring only correctly weighted products proceed to packaging, dispatch, or downstream operations.
Real-Time Data Monitoring
Tracks weight data and line performance in real time — providing production statistics for quality control reporting, process optimization, and regulatory compliance.
System IntegrationSystem Integration
Integrates with fillers, labellers, and packaging machines — forming a complete, connected quality control system within the production line.
Flexible Weight Range
Handles a wide variety of product sizes and weights from small sachets to large cartons and cases — with models available for standard, high-speed, and heavy-duty applications.
Static Model for Precision Applications
Static checkweighers allow operators to manually adjust product weight to target with clear system prompts — ideal for bulk commodities and high-precision applications.

Frequently asked questions
Alpha Pack makes packaging simple — from machine selection and installation to training and after-sales support, we’re here to help every step of the way.
What is the difference between a dynamic and static checkweigher?
A dynamic checkweigher weighs products while they move on a conveyor — ideal for high-speed automated lines. A static checkweigher weighs products while stationary, allowing manual weight adjustment — suitable for slower processes or heavy, bulky items.
What happens to products that fail the weight check?
The automatic rejection device removes non-compliant products from the line immediately — ensuring only correctly weighted products proceed to the next stage of production or dispatch.
Can checkweighers integrate with existing packaging lines?
Yes. Checkweighers integrate with fillers, labellers, sealers, and packaging machines — connecting seamlessly into existing automated production lines without major modification.
Do checkweighers provide production data and reports?
Yes. Real-time data monitoring tracks weight measurements and line performance — generating production statistics for quality control records, compliance reporting, and process optimization.
