Detection size

2–50 mmThe sheet does not say whether this is length, head diameter or another dimension.

Counting rate

8,000–10,000 pcs/minThis is pieces per minute. It is not a finished-bag rate.

Counting error

0.03%, positive errorThe sheet records 0.03% and says the error is positive: the count may run high, not low. It does not state the sample size, batch setting or acceptance method.

Bag size

150–450 mmThe sheet does not say whether this is width, length or film width.

Item	Specification	Application and conditions
Detection size	2–50 mm	The sheet does not say whether this is length, head diameter or another dimension.
Counting rate	8,000–10,000 pcs/min	This is pieces per minute. It is not a finished-bag rate.
Counting error	0.03%, positive error	The sheet records 0.03% and says the error is positive: the count may run high, not low. It does not state the sample size, batch setting or acceptance method.
Bag size	150–450 mm	The sheet does not say whether this is width, length or film width.
Film	PE film	Recorded packaging material. Thickness is not on this sheet.
Power supply	AC 220 V ±10%, 50/60 Hz	Recorded as AC 220 V ±10%, 50/60 Hz. Rated watts and compressed air are not on this sheet.

This counter is specified for precision small screws. The sheet records a detection size of 2–50 mm and does not split that number into screw length and head diameter. It also records a bag size of 150–450 mm without saying whether that is width, length or film width, and it records PE film.

How to read the recorded count

The sheet records 0.03% and says the error is positive: the count may run high, not low. It does not state the sample size, batch setting or acceptance method.

This is pieces per minute. It is not a finished-bag rate. A finished-bag rate depends on the pieces in each bag, the film and how the parts separate. Compare the LINEVO fastener packing range.

What this sheet does not state

The sheet does not list machine weight, rated watts, compressed air, a warranty or a price. Photos show the equipment. They are not a supply list. Send the parts and the pack.

The same counting rate and error wording appear on other sheet rows. This page uses only the precision-screw row. It does not claim those other machines are the same configuration. The multi-channel counter records a higher piece rate, and the warehouse counter does too.

Frequently Asked Questions

Where do these figures come from?

Each figure is copied from the equipment sheet for this configuration. A blank cell stays blank, and a piece rate is not rewritten as bags per minute.

What should I send for a quotation?

Send the parts, the target count or weight, a bag or carton sample, and the delivery country and city. LINEVO confirms fit and output on those samples.

LINEVO ENGINEERING & SAMPLE TESTING

Check the fastener, the pack and the finished result.

LINEVO can arrange project sample tests and video demonstrations with representative parts and packaging material. Agree the configuration, measurements and test record before sending samples.

Prepare production samples

Use fasteners from a normal production batch and the bag, pouch or carton you intend to ship. Include the count or weight, the pack drawing, the target output and any sizes that tangle or jam. Confirm quantities and shipping instructions with our team first.

Define measurable checks

Agree the count or net-weight target, how many packs to check, the seal checks and the timed count of acceptable packs. Include feeder jams, pouch opening and carton counts where they affect the selected machine.

Carry the criteria into acceptance

Define the factory acceptance test (FAT) scope in the order: configuration, materials, run conditions, pass criteria and records to deliver. Agree whether you need a written record, run video or returned packs for your quality team.

Seal quality: agree the evaluation method with your packaging team. ASTM F88/F88M covers seal separation force and failure mode for flexible barrier materials. Set pack-specific limits separately from a visual check for parts trapped in the seal.

Count and weight: recount or reweigh finished packs at the agreed discharge. A counter pulse or a scale setpoint is not the same record as a saleable bag. For retail packs, NIST Handbook 133 is a reference for checking the net contents of packaged goods.
