In modern industrial food processing, speed, efficiency, and accuracy are no longer distinct requirements; they are closely integrated. As global packaging demands increase, the reliance on high-speed combination multihead weighers has grown significantly. Ningbo Nexa Machine Co., Ltd. is at the forefront of this industrial shift. As an established Chinese manufacturer and exporter, we design and assemble multihead weighing machinery that helps processors worldwide reduce product giveaway, lower operating costs, and improve packaging efficiency.
In automated packaging, multihead weighing serves as the core system for portioning. Using a series of feed hoppers, weigh hoppers, and memory units, these systems run mathematical combination calculations to select the exact combination of hoppers that matches a target weight. With typical accuracy ranges between ±0.1g and 1.5g, our machines reduce product giveaway compared to standard volumetric or single-head fillers. This efficiency improvement direct increases profitability for modern manufacturing operations.
Our weighers utilize Digital Signal Processing (DSP) technology coupled with strain gauge load cells, eliminating industrial vibration interference for reliable measurement cycles.
Integrated microprocessors perform tens of thousands of mathematical weight combinations in milliseconds, instantly selecting the optimal bucket combination to match target yields.
Manufactured with full SUS304 structure, IP65/IP67 ingress ratings, and tool-free quick-disassembly hoppers, reducing cleaning downtime and cross-contamination risks.
Ningbo is a major industrial city in China, home to advanced metalworking, engineering talent, and well-connected shipping lanes. Leveraging this industrial cluster, Ningbo Nexa Machine Co., Ltd. builds high-performance machinery that balances cost and quality. Our vertical integration allows us to design, machine, assemble, program, and inspect our packaging systems completely in-house.
The manufacturing process uses CNC laser cutting systems, precise bending machinery, and automated welding lines to ensure structural integrity across our equipment lines. This strong supply base lets us source durable materials and components, such as high-grade pneumatic systems and PLC controls, while keeping equipment costs competitive for global purchasers.
Operating in international markets requires strict adherence to regional safety and technical regulations. At Ningbo Nexa Machine Co., Ltd., we build our machines to meet international standards, including European CE Certification, North American UL/CSA electrical parameters, and global FDA food-contact material regulations.
We recognize that purchasing machinery involves ongoing, long-term support. Our global customer care system provides remote diagnostic support, direct visual setup assistance, and partnerships with local technical groups in Europe, North America, and Southeast Asia. These partnerships allow us to offer timely installation, commissioning, operator training, and replacement parts service to minimize downtime at your facility.
Different materials require specific handling setups. Our product line matches different product properties with suitable hopper styles, surface finishes, and control parameters.
| Machine Model Style | Target Applications | Weighing Range | Max Speed | Hopper Volume | Surface Options |
|---|---|---|---|---|---|
| 4-Head Linear Weigher | Fine Granules, Powders, Seeds, Salt, Coffee Beans | 10g - 2000g | 45 bpm | 1.6L / 3.0L | Flat SUS304 / Sandblasted |
| 10-Head Combinational | Mid-size Snacks, Chips, Pet Food, Beans | 10g - 1500g | 70 bpm | 1.6L / 2.5L | Dimpled Sheet / Teflon Coated |
| 14-Head High-Speed | Confectionery, Nuts, Frozen Vegetables, Hardware | 10g - 3000g | 120 bpm | 1.6L / 2.5L | Dimpled / Anti-condensation |
| Multi-lane Stick Pack | Spices Powder, Chilli, Liquid portion cups | 1g - 100g | Multi-lane dependent | Continuous Fill | Electropolished SUS316 |
Industrial procurement teams look for more than standalone machinery; they search for modular packaging lines that integrate into their existing setups. Our design approach focuses on system compatibility. We ensure our multihead weighers connect cleanly with Vertical Form Fill Seal (VFFS) units, pre-made pouch packagers, cartoning machines, and bottling conveyors.
Using open industrial communication protocols (such as Modbus, Profinet, and EtherCAT), our machines send real-time weight information, throughput metrics, and diagnostic alerts back to plant-wide SCADA or MES platforms. This connectivity helps engineering managers track output rates, monitor equipment health, and maintain product quality across their lines.
Instead of relying on a single hopper to hit a target weight, the machine spreads product across multiple weigh hoppers. The CPU reads the weight in each hopper and calculates which combination of hoppers comes closest to the target weight without going under. It then releases the selected hoppers, achieving high accuracy at speed.
Flat stainless steel works well for dry, free-flowing items like beans, seeds, and hardware. Dimpled surfaces are designed for sticky or moist items like dried fruit, gummy candy, or wet pet food. The dimpled pattern reduces the surface area contact, preventing the product from sticking to the hoppers and keeping production moving.
Our weighers feature digital vibration filters built into the DSP load cells. This system filters out low-frequency and high-frequency factory floor vibrations (such as those from nearby mixers or packaging lines), allowing the load cells to capture clean weight readings.
We provide IP65-rated enclosures that protect the machine during washdowns, along with dust-proof enclosures and suction points for handling dusty powders. All food-contact parts are designed for tool-free disassembly, making cleaning and sanitation straightforward.
Our engineering team works with customers to design custom layout configurations, feed systems, and output chutes. We match our machinery to your factory footprint, ceiling heights, and upstream feeding setups to ensure a smooth installation process.
