Conveyor Metal Detection Solutions
Detect and remove metal contaminants to ensure product safety, regulatory compliance, and brand protection across your automated production line.
Why it matters
A Tiny Metal Fragment Should Never Reach Your Customer
We not only manufacture products, but also provide brand owners with complete market solutions to help you reduce risks, enhance competitiveness, and accelerate market success.
Safety Recalls & Brand Damage
Even a microscopic fragment can trigger safety scares, costly recalls, and the loss of hard-earned customer trust overnight.
Regulatory & Compliance Pressure
HACCP, FDA, GMP, IFS, GFSI and FSMA set strict purity rules. Failing detection can mean fines, shutdowns, or lost licenses.
Line Speed vs. Accuracy
Slow or inaccurate detection slows your line, drives up costs, and risks unsafe product shipping. Balancing speed, sensitivity and cost is the real challenge.
Reliable Detection for Every Production Scenario
In today’s automated production environments, maintaining product quality and consumer safety is critical to business success. Yet metal contaminants—from machine wear, raw materials, or human error—can severely damage your brand and bottom line.From backend pipelines to foil-packed goods and integrated checkweighing, SameGram delivers high-sensitivity systems engineered for automated manufacturing lines.
Pipeline Metal Detection for Bulk & Flowing Product
Undetected metal in backend pipelines compromises food safety and GFSI compliance, leading to costly recalls. Traditional detectors often lack the precision for diverse products, raising false positives.
Our metal detector conveyor uses advanced digital signal processing and a touch-screen interface to deliver high sensitivity (FE ≥0.6mm, SUS304 ≥1.2mm), with IP67 waterproof and shockproof design, customizable frequencies, and 100+ product memory.

Dual-Frequency Detection for Packaged Products
Using dual-frequency magnetic field detection and digital signal processing, our systems achieve high sensitivity (FE ≥0.5mm, SUS304 ≥1.0mm) across diverse packaging.
Self-learning algorithms and automatic balance compensation eliminate interference from high-salt or moist products. IP66/IP67-rated 304 stainless steel builds thrive in demanding environments, with belt speeds of 1–1000 m/min, 7-inch LCD, 100+ product memory and USB data export.

Frequently Asked Questions
- Will it work with my product and packaging?Detection figures are typical unloaded values and vary with product density and pack format. SameGram offers on-site testing and a 1000+ SKU library to confirm performance before purchase.
Detection figures are typical unloaded values and vary with product density and pack format. SameGram offers on-site testing and a product library of 1000+ SKUs to confirm real performance before you buy.
What affects detection on your line
- Product density — higher density contrast improves detectability.
- Pack format — foil, metallized, or multilayer wraps change the read.
- Contaminant type & size — denser and larger objects are easier to catch.
- Line speed — throughput settings tune sensitivity vs. capacity.
SameGram runs an on-site test on your actual product and packaging, then matches it against a 1000+ SKU library so the quoted performance is real, not theoretical.Request an on-site test → - Does it detect non-metal contaminants like plastic or paper?Yes. Beyond metal, glass, stone, and bone, the systems detect dense rubber, hard plastics, ceramics, and internal paper inserts left in sealed packs.
Yes. Beyond metal, glass, stone, and bone, SameGram X-ray systems detect dense rubber, hard plastics, ceramics, and even internal paper inserts (labels, leaflets) left inside sealed packs.
Non-metal contaminants it can catch
- Dense rubber & hard plastics — e.g. conveyor or machine fragments.
- Ceramics & stone — chips from kiln or processing wear.
- Glass shards — from jars, bottles, or broken containers.
- Internal paper inserts — misplaced labels or leaflets sealed in the pack.
Detection depends on density contrast versus the product. Very low-density items may need verification — SameGram confirms on-site before purchase.Check detection capability → - Can it inspect aluminum foil or metallized packaging?Yes. Unlike metal detectors, X-ray detects contaminants inside foil, metallized film, and multilayer packaging by density, not conductivity.
Yes — and this is a key advantage over metal detectors. X-ray identifies contaminants inside aluminum foil, metallized film, and multilayer packaging by density, not conductivity, so the pack material no longer blocks inspection.
X-ray vs. metal detector on tricky packaging
Packaging type Metal detector SameGram X-ray Aluminum foil pouch Signal blocked Inspects by density Metallized film Signal blocked Inspects by density Multilayer laminate Often blind Detects metal & non-metal Because X-ray reads density differences, it also finds glass, stone, bone, and dense plastic inside these same packs — not just metal.See X-ray inspection specs → - Is X-ray inspection safe for operators?Yes. SameGram X-ray systems keep operator radiation leakage below 1 µSv/h and stop the beam via enclosure interlocks when opened.
Yes — X-ray inspection is safe for operators. SameGram systems are engineered for radiation safety: seafood models measure X-ray leakage below 1 µSv/h, well within international exposure limits, and enclosure interlocks stop the beam the moment a panel is opened.
How operator safety is built in
- Leakage control — seafood models measure X-ray leakage below 1 µSv/h, far under international limits.
- Interlock protection — the beam cuts off automatically when an enclosure is opened.
- Contained enclosure — radiation is sealed within the inspected zone during operation.
Figures are typical unloaded values. SameGram validates every installation against applicable radiation-safety standards before handover.Browse the Products & Technology FAQ → - Q: What is a dynamic checkweigher?Dynamic weighing ensures 100% inline inspection.A:Dynamic checkweigher automatically weighs products while moving on a conveyor, without stopping production.
- Q:Can the system be integrated with my production line?X-ray inspection systems can be integrated with production lines, supporting PLC/MES control, automatic reject mechanisms, and data reporting for seamless quality control.
A:
Yes, modern X-ray inspection systems are designed for production line integration. They can connect to PLC and MES systems, allowing automatic control, real-time data monitoring, and quality reporting. Most systems also support reject mechanisms to remove contaminated or defective products without stopping the line, ensuring efficient, continuous operation while maintaining high detection accuracy.
