Checkweigher from China

Brochure accuracy is taken with a still test weight; on your line it depends on belt speed, pack spacing and vibration from the machine next door, and the reject must prove the bad pack actually left.

What you are actually comparing.

Two quotes, one machine name

What hides inside the price

Accuracy at speed

Ask for accuracy as plus or minus grams, at your pack weight and packs per minute. A percent of full range hides a poor result on light packs.

Reject and confirmation

Pusher, air jet or drop belt. Ask for a sensor confirming each reject and a locked reject bin.

Integration

Feedback to the filler lets the checkweigher trim fill weight. Ask which signals and protocol are offered.

Data

Ask how batch totals and reject counts are stored and exported for your records.

Before you ask for a price.

Send these with the enquiry. Without them, any number a factory gives you is a guess dressed as a quotation.

Pack weight range, size and packs per minute.
Your tolerance on each pack.
Infeed and outfeed height and direction.
Whether you need metal detection in the same frame.
Whether the weight record is your legal quantity proof.

Where the numbers come from.

We name the kind of source, how many and when, and never the factory. Listed prices are asking prices, not landed cost. Where we do not hold a fact we say so: that is a GAP, not an estimate.
