Linear weigh fillers
Good for moderate outputs, multiple products and controlled dry product dosing.
View routeInspection lines
Metal detector and checkweigher lines
Plan inspection equipment after filling where pack safety, weight control and reject handling are required.
Planning the right weigh filling route
Dry product packing lines may require metal detection, checkweighing or both. The inspection equipment should be positioned where the pack is stable and representative of the finished product.
A combined inspection route can reduce line length, but the correct arrangement depends on pack type, conveyor speed, reject method and site standards.
Inspection should be specified alongside the filler, not added later without checking available space and product flow.
Key buying checks
- Check finished pack size and stability.
- Confirm reject method and reject bin capacity.
- Review metal detection sensitivity expectations.
- Allow access for testing and cleaning.
Routes to compare
Machine options to shortlist.
Inspection equipment should support the filling line output without causing unnecessary stoppages.
Multihead weighers
Useful where speed, accuracy and product combination are central to the project.
View routeAuger fillers
Often compared for powders, fine ingredients and products that need screw dosing.
View routeVFFS weigh lines
For automatic bag forming, weighing, filling and sealing from film reels.

FAQ
Questions before choosing a weigh filler.
Short answers for production teams comparing dry-product weighing and filling routes.
What information is needed for metal detector and checkweigher lines?
Useful details include the product name, bulk density if known, target fill weight, acceptable tolerance, pack format, output per minute or hour and whether the line must connect to feeding, sealing, capping, labelling or checkweighing equipment.
Which machine type is normally compared for metal detector and checkweigher lines?
Linear weighers, multihead weighers and auger fillers may all be considered depending on product flow, dose size and output target.
Can Lancing help with a complete line rather than a standalone filler?
Yes. Many projects involve product feed, weighing, filling, pack handling, sealing or closing and downstream checking. Sending the full pack route helps avoid choosing a filler that later becomes difficult to integrate.
Send the product, target weight, pack format and output target.
Lancing can advise whether a linear weigher, multihead weigher, auger filler, VFFS line or integrated route is the practical starting point.
