Why Choose MQ-MCL4530L2
2-in-1 combo saves line space
An electromagnetic-induction metal detector and a digital load cell are tightly integrated on a single stainless-steel frame, so every product passes through metal detection and weight verification in one run. Compared with installing two separate machines, you save one conveyor section and one operator station, and wiring, commissioning and maintenance are all done just once — a visibly simpler line layout.
Missing pieces caught at 0.1g resolution
With 0.1g display resolution, a 1-2000g weighing range and ±0.3-1g accuracy, the gram difference caused by one or two missing pieces in count-packed products like sanitary pads or wet wipes falls squarely within detection range. Short-count packs are rejected right on the line — no waiting for a customer complaint to find out.
Broken needles and blade chips detected at millimeter level
Empty-conveyor sensitivity: Fe 0.6-1.2mm, non-ferrous 0.8-1.5mm, stainless steel SUS 1.2-2.0mm. Metal debris from chipped die-cutting blades or worn machinery is identified by the electromagnetic-induction aperture at millimeter scale and automatically rejected, stopping foreign metal before it leaves the factory — meeting the foreign-body control requirements of major FMCG factory audits.
100 product presets — no re-tuning at changeover
The machine stores up to 100 product recipes. Switching toilet-roll sizes or day/night sanitary pad variants only takes recalling the matching preset — no re-learning or recalibration needed. Belt speed is adjustable from 5-28 m/min to match product weight and throughput, dramatically cutting changeover time for high-mix, small-batch FMCG plants.
Auto reports, plug-and-go USB export
Built-in report statistics generate inspection data directly in EXCEL format, exportable in real time via USB stick. Batch pass rates and rejection records are always on hand for review and archiving — let the data speak during customer audits or quality traceability, with no manual logbooks to fill in.
Power-on self-check, no blind running
Every startup runs an automatic fault check with on-screen prompts. If a sensor or the rejection mechanism is abnormal, the machine alarms first instead of running impaired and letting defective packs slip through. Combined with hazard alerts, an emergency stop button and safety guards, operators can work safely from day one.
Problems It Solves for You
Buying a metal detector and a checkweigher separately means two machines occupying two conveyor sections — tissue and sanitary pad packing lines are long enough already, the floor can't fit them, and two systems mean double the training and maintenance
Integrated metal detection + checkweighing design: one machine and one conveyor section handle both inspections, running off a single AC220V supply — saving floor space and maintenance workload
Sanitary pads and wet wipes are packed by piece count; when equipment occasionally drops one or two pieces, manual spot checks simply can't catch it, and short packs reach retail shelves triggering complaints or even delisting
Full-range 1-2000g in-line weighing of every pack, with 0.1g display resolution and ±0.3-1g accuracy — the gram deviation from missing pieces is identified in-line, and a pusher or slide-type rejector automatically removes short-count packs
Metal chips from worn slitting knives and sealing dies get into toilet rolls and wet wipes; export orders and key-account audits have zero tolerance for metal contamination, and one finding means the whole batch is returned
The electromagnetic-induction aperture reaches empty-conveyor sensitivity of Fe 0.6mm and SUS 1.2mm — millimeter-scale metal debris is detected in-line and auto-rejected, with EXCEL-exportable records serving as traceability evidence
QA demands monthly pass-rate reports, but line data is logged by hand — omissions and errors are common, and when tracing a batch the complete records are nowhere to be found
Built-in report statistics generate data in EXCEL format in real time, with plug-and-export USB output — complete batch records on file, ready to pull up instantly for audits and traceability

Functions in Detail
Rejection: pusher or slide type, matched to your product
Two rejection mechanisms come as standard options: pusher type and slide type. Packs with some weight and rigidity — toilet rolls, diapers — suit the pusher type for direct force and precise placement; soft, lightweight bags like wet wipes and face masks can take the slide type for gentle rejection that won't damage packaging. Tell us your product format when ordering and the factory configures accordingly.
Detection principle: electromagnetic induction + digital weighing, two independent systems
The metal detection stage uses electromagnetic induction with an aperture of H 120mm×W 300mm — disturbances to the magnetic field as products pass are analyzed in real time to judge metal content. The weighing stage uses a digital load cell on an L 450mm×W 230mm platform, delivering dynamic readings at 0.1g resolution. Each system triggers rejection independently without interfering with the other.
Data management: EXCEL reports with real-time USB export
A built-in statistics module automatically tallies total inspected, passed and rejected counts per recipe, generating reports directly in EXCEL format — just plug a USB stick into the front panel to export in real time. QA gets a print-ready electronic ledger with no host software required and no manual transcription.
Safety: self-check + emergency stop + guarding
Automatic fault detection runs at every startup with abnormalities flagged on screen, preventing invalid inspection from an impaired machine. During operation the machine provides hazard alerts, carries an emergency stop button, and shields the rejection zone with safety guards so operators clearing jams never touch moving parts — in line with FMCG plant safety management requirements.
Build and installation: stainless steel 304, AC220V plug-and-play
The housing is stainless steel 304, resistant to cleaning-agent wipe-downs and humid FMCG workshop conditions without corroding. Power is single-phase AC220V±10%, connecting straight into standard workshop circuits with no three-phase rework. Belt speed adjusts from 5-28 m/min to synchronize with upstream packing and downstream cartoning machines for in-line operation.
Industries & Application Scenarios
In-line inspection at the end of roll and facial tissue packing lines: weight verification confirms roll length and sheet count are on spec while simultaneously detecting metal debris from worn slitting blades. Inspectable size L≤350mm, H≤100mm covers standard multi-pack formats.
Per-pack weighing after packaging, with one-touch switching across day/night variants via 100 stored recipes. Short-count packs are rejected in-line while the metal detection aperture intercepts debris from embossing rollers and cutters — meeting brand-owner audit requirements.
In-line checkweighing on wet wipe lines: weight deviations from insufficient lotion dosing or missing sheets are captured at 0.1g resolution, and the stainless steel 304 body withstands workshop humidity and routine wipe-down cleaning.
Count-based per-pack weighing for diapers, with the 1-2000g range covering trial packs through jumbo packs. Short packs are auto-rejected, and inspection data exports via USB for e-commerce platform and retail supplier audits.
Double-check bagged products like face masks and cotton towels before shipment — metal contaminants and net content verified in a single pass. The H120mm×W300mm detection aperture suits mainstream flat bagged packaging.
OEM plants juggling frequent changeovers across brands and formats recall stored recipes with no recalibration, adjust belt speed 5-28 m/min to each brand's takt, and export batch inspection reports to hand over to brand QA teams.

Was FSMA 204 Really Delayed to July 2028? What Every Other Article Gets Wrong
Almost every article on page one says FSMA 204 "was delayed to July 2028." That sentence is imprecise in a way that matters. FDA did publish a delay document on 7 August 2025 (90 FR 38084, document 2025-14967, docket FDA-2014-N-0053) — but it is a proposed rule, and as of 16 July 2026 it has never been finalized. The original compliance date of 20 January 2026 is still sitting in the regulation as written; it was never formally amended. What actually pushes the practical date to 20 July 2028 is a congressional appropriations act (P.L. 119-37), which works as an enforcement funding prohibition rather than as FDA rulemaking. That distinction changes what you can rely on, for how long, and what your legal team should be told. This article walks the timeline precisely, then addresses the second myth: that FSMA 204 requires checkweighers, metal detectors or X-ray systems. It does not. It has zero equipment requirements. We explain which regulation actually applies, and give you a checklist you can run this week.
Indonesia's 17 October 2026 Halal Deadline: What It Actually Means for Your Inspection and Weighing Equipment
On 17 October 2026, Indonesia's mandatory halal certification obligation reaches imported food and beverages, and also reaches Indonesian micro and small food and beverage enterprises. The date comes from Government Regulation PP 42/2024, which set a grace period ending no later than 17 October 2026. This article answers the question exporters keep asking equipment suppliers: does a checkweigher, metal detector, or X-ray inspection machine need to be halal certified? The short answer is that certification attaches to products, not to machines — but the machines still show up in the file, because the certification body has to be satisfied that nothing on your line contaminates the product. We walk through the two-phase structure behind the date, the meat and dairy carve-out that trips up importers, how foreign halal certificates are recognised through mutual recognition agreements with BPJPH, and what exemptions exist. Then we give you a checklist you can hand to your engineering team, written by people who build the equipment rather than sell the certificate.
No, Your Checkweigher Is Not "FSMA 204 Compliant" — Here's the Regulation That Actually Applies
Search "FSMA 204 compliant checkweigher" and you will find vendors selling machines against a rule that says nothing about machines. FSMA 204 is a recordkeeping regulation. Read the text on eCFR and you will find zero equipment requirements — no weighing requirement, no metal detection requirement, no X-ray requirement, no performance specification of any kind. No device can be "FSMA 204 compliant," and no device is "required by FSMA 204." This article explains what the rule actually governs, identifies the regulation that does create the hook for inspection and weighing equipment (21 CFR Part 117 — which itself never names a single machine), and separates net-content law (FPLA, 21 CFR 101.7(q), NIST Handbook 133) from food-safety law, a confusion that costs buyers real money. Includes a myth-versus-fact section, a five-question script for auditing any vendor's compliance claim, and guidance on specifying equipment against the regulation that genuinely applies to your line.
