Checkweigher and weigh filler line planning for dry products.
Plan weigh filling, verification, rejection, coding and downstream handling as part of one line route.
Application planning
A weigh filler controls the dose going into the pack, while a checkweigher can verify finished pack weight after filling and sealing. The two functions are different and should be planned around tolerance, speed and quality control requirements.
For some products, the filling machine can be set to reduce giveaway. For others, finished-pack checkweighing, rejection and data capture may also be required for production control.
Key planning points
- The weigh filler doses product before or during pack filling.
- A checkweigher verifies the finished pack after filling.
- Tolerance and legal requirements should be discussed early.
- Reject handling, conveyors and line speed affect layout.

FAQ
Checkweigher and weigh filler line planning for dry products questions.
Short answers for production teams comparing weigh filling routes.
Is a weigh filler the same as a checkweigher?
No. The weigh filler doses product into the pack; a checkweigher usually verifies the finished pack weight afterwards.
Do all lines need a checkweigher?
Not always. It depends on the product, tolerance, production control requirements and finished pack process.
Can a checkweigher be added later?
Sometimes. Space, conveyor height, speed and reject handling should be considered if a future checkweigher is likely.
Send the product, target weight, pack format and output target.
That gives Lancing enough information to compare a linear weigher, multihead weigher, auger filler or integrated bagging line.
