Dynamic inline carton checkweighing
Checks every presented pack against a programmed weight tolerance to identify underweight or overweight units.
Checks every presented pack against a programmed weight tolerance to identify underweight or overweight units. The final configuration is developed from approved product samples, process requirements and production targets.

Machine overview
H M Pharma Machines manufactures the Carton Weight Checker in Ahmedabad, Gujarat, India for pharmaceutical, nutraceutical, cosmetic, food, chemical and allied production applications.
Checks every presented pack against a programmed weight tolerance to identify underweight or overweight units. An infeed belt spaces cartons, a dynamic weigh conveyor measures each pack and the controller passes or rejects it against the selected recipe.
Output, format range, construction, controls, utilities and optional equipment are finalized against the customer-approved sample, drawing, process details and user requirement specification.
Configuration summary
Final machine selection is based on approved samples, process details, target output and the required level of automation.
