Weighing and Inspection Machines for Packaging Lines
This page is the packaging-line entry for weighing and inspection equipment from LEKA Pack Line: in-motion checkweighers, conveyor / food metal detectors, food X-ray inspection, and checkweigher + metal detector combinations. We support buyers in North and South America, Western and Eastern Europe, and Southeast Asia. Catalog figures are empty-machine references and are confirmed during project review.
Where these machines sit on a packaging line
A common bottle path is filling → capping → in-motion checkweigher → conveyor metal detector or food X-ray → labeling. Exact order depends on process, metal lids, and QA rules. LEKA Pack Line can review a standalone inspector or how it connects with existing filling machines, capping, labeling, or a complete liquid filling line. Provide belt height, line speed, and left/right discharge when requesting a retrofit review—no fixed rebuild timeline is promised from catalog data alone.
About LEKA Pack Line / catalog references
LEKA Pack Line supplies in-motion checkweighers, conveyor and foil metal detectors, gravity separators, food X-ray systems, and checkweigher + metal detector combinations—selected by packaging form and inspection goal. Sensitivity and accuracy figures are empty-machine / no-product references; they are not rated or guaranteed values and must be confirmed during project review.
Weighing and inspection machine families
This hub is the entry and internal-link map. Deep specifications stay on each family or machine page. Open a family to compare models, empty-machine reference bands, and reject options.
In-motion checkweigher
An inline, dynamic checkweigher verifies finished-pack weight on a moving belt and rejects under- or over-weight packs.
Weight check after filling. Deep specs stay on the checkweigher family page.

Conveyor metal detector
A conveyor / food metal detector finds Fe, Non-Fe and SUS in belt-fed packs on a packaging line.
Detects (catalog ref.)
Checkweigher metal detector combination
One footprint for in-motion checkweighing and conveyor metal detection, with a shared reject path.
Detects (catalog ref.)
Aluminum foil packaging metal detector
Ferromagnetic detection for foil / film packs.
Detects (catalog ref.)
Gravity / free-fall metal separator
Free-fall powder and granule separation.

Food X-ray inspection
Food X-ray inspection looks for dense foreign objects in bags, boxes and bottles when metal detection is not enough.

Choose by contaminant type and weighing need
Metal detection and X-ray are complementary. Checkweigher accuracy depends on pack, speed and environment—confirm with samples.
Metal detector vs X-ray
Conveyor metal detectors focus on conductive metal contaminants with practical cost and belt speed. Foil packs usually need the dedicated foil model. Food X-ray inspection helps when glass, ceramic, or other dense non-metal objects matter. They are complementary. Final selection is confirmed during project review.
What affects checkweigher accuracy
Product shape and stability, belt speed, vibration, weighing range, and minimum division all matter. Catalog accuracy is a reference band, not a contract guarantee. Send samples or detailed pack data so LEKA Pack Line can review a realistic band for your line.

Empty-machine (no-product) reference sensitivity figures are theoretical references without product effect; actual detectable size depends on product, packaging, and line conditions and is confirmed during project review. Actual results depend on product and environment; confirmed during project review. Rejection methods are optional / customized (pusher, flap, air blow, swing arm).
Frequently asked questions
What checkweigh and foreign-object inspection equipment does LEKA Pack Line offer?
LEKA Pack Line supplies in-motion checkweighers, conveyor metal detectors, aluminum-foil metal detectors, gravity metal separators, food X-ray inspection systems, and checkweigher + metal detector combinations. Selection depends on packaging form and what you need to detect or verify.
Metal detector vs X-ray: which should I choose for my line?
Conveyor metal detectors focus on conductive metal contaminants (Fe, Non-Fe, SUS) with practical cost and speed. Foil packs usually need a dedicated foil detector (LK-807). Non-metal foreign objects such as glass or ceramic, or complex packs, may suit X-ray. Final choice is confirmed during project review with your product and regulatory needs.
Can I treat catalog figures as on-product performance?
Empty-machine (no-product) reference sensitivity figures are theoretical references without product effect; actual detectable size depends on product, packaging, and line conditions and is confirmed during project review.
