Explore China’s leading industrial-grade combined checkweigher and metal detector systems engineered for zero-defect production lines, compliant with FDA, HACCP, BRCGS, and IFS standards.
In high-speed food processing, pharmaceutical manufacturing, and consumer packaged goods (CPG) packaging lines, operational efficiency and quality compliance are non-negotiable. Historically, quality managers were forced to install standalone conveyor belt metal detectors and separate inline checkweighing scales. This traditional setup required extensive floor space (often exceeding 3.5 meters of linear conveyor length), complex multi-vendor software integration, redundant electrical control cabinets, and elevated maintenance overhead.
As a leading China checkweigher and metal detector combo factory and supplier since 1996, we have pioneered the integration of electromagnetic metal detection with high-speed strain gauge and Electromagnetic Force Restoration (EMFR) dynamic checkweighing into a singular, compact, mono-frame architectural system. By combining both critical control point (CCP) functions into a unified footprint (reducing conveyor length by up to 45%), global manufacturers achieve superior operational control, zero product giveaways, absolute foreign contaminant elimination, and full compliance with FDA 21 CFR Part 11, HACCP, BRCGS, and IFS auditing standards.
Integrating a combined metal detector checkweigher machine cuts capital expenditure (CapEx) by 25-35% compared to purchasing separate systems, while reducing line setup footprint and unifying data reporting through a single 10-inch Siemens/Omron industrial HMI touch interface.
Our combo systems combine cutting-edge Digital Signal Processing (DSP) with ultra-sensitive strain gauge load cells to provide unmatched accuracy and detection sensitivity.
Independent Digital Signal Processors handle metal detection and dynamic weight processing simultaneously. Phase discrimination algorithms suppress product effect caused by high-moisture or conductive salted foods.
Utilizing high-end sensors sourced from world-class suppliers, our dynamic weighing bridge achieves up to ±0.1g accuracy at speeds of up to 250 packs per minute with automatic zero-tracking and dynamic belt compensation.
Capable of simultaneously detecting Ferrous (Fe), Non-Ferrous (NFe), and Stainless Steel (SS316) contaminants down to 0.4mm Fe, 0.6mm NFe, and 0.8mm SS, even inside metallized film foil packaging.
Equipped with dual independent rejection channels (Pneumatic Pusher, Air Blast, Drop-Belt, or Flipper Arm) to separate weight-out-of-spec packages from metal-contaminated packages into lockable bins.
Constructed entirely from SUS304 or SUS316L food-grade stainless steel with toolless quick-release conveyor belts for effortless high-pressure washdown hygiene control in raw meat and dairy environments.
Supports Modbus TCP, Ethernet/IP, OPC-UA, and USB data export. Real-time SPC statistics, weight distribution histograms, and audit trail logs ensure seamless ERP/MES integration.

Anticipate technology shifts to maximize your equipment ROI over the next decade.
Traditional metal detectors require manual operator calibration to filter out product effect from high-salt or frozen foods. Modern combo machines feature artificial intelligence algorithms that continuously learn and dynamically adjust phase angles in real-time, drastically reducing false rejection rates.
Procurement teams are shifting toward smart factories where checkweighers automatically send feedback signals to upstream multihead weighers or volumetric auger fillers. This closed-loop control system automatically adjusts filling quantities, eliminating costly product giveaway.
Single or dual-frequency metal detection is being replaced by multi-simultaneous frequency spectrum scanning technology. This allows detection of spherical and wire-shaped stainless steel contaminants across varying moisture levels without recalibration.
Strict food safety regulations dictate that cleaning down times must be minimized. Next-generation combo systems feature toolless belt disassembly, open-frame stainless steel channels, and IP69K washdown enclosures for rapid sanitation cycles.
Clear answers to technical, operational, and shipping questions regarding combo checkweigher and metal detector systems.
A combo unit saves up to 45% of floor space on your packaging line, reduces equipment acquisition cost by 25-35%, unifies your operational software into a single touch-screen interface, and simplifies audit logging for FDA, HACCP, BRCGS, and IFS compliance.
Our combined systems feature independent dual-reject mechanisms (such as dual pneumatic pushers or air jets) leading to two separate, key-locked reject catch bins. This guarantees that metal-contaminated products are never mixed with under/over-weight products.
Typical sensitivity ranges from 0.3mm to 0.8mm for Ferrous (Fe), 0.5mm to 1.2mm for Non-Ferrous (NFe), and 0.6mm to 1.5mm for Stainless Steel (SS316), depending on aperture height, product size, and moisture content (product effect).
Yes. We offer specialized multi-frequency metal detection heads engineered to work through aluminum foil bags, as well as magnetic induction detectors designed specifically for inspect-after-canning applications.
