12 Head Automatic Net Weight Filling Machine 1-5kg Production Capacity Up To 3600 BPH

In the North American daily chemicals (e.g., laundry detergents, shampoos), auto care (e.g., lubricants, coolants), and fine chemicals markets, packaging large-volume (1-5kg) free-flowing liquids presents two major challenges: overflow contamination caused by material foaming, and weight discrepancies due to volumetric filling under fluctuating temperatures (resulting in "product giveaway"). This 12-Head Automatic Net Weight Filling Machine is meticulously engineered to eradicate these pain points. By merging the extreme accuracy of gravity-fed weighing with the high throughput of a back-to-back architecture, it delivers an unparalleled return on automation investment for Contract Manufacturing Organizations (CMOs).

Expensive chemical raw materials permit zero unnecessary waste. Each of the 12 filling heads on this machine is equipped with an independent weighing and feedback system, supporting both gross and net weight modes. The filling process utilizes an advanced "two-stage (coarse and fine) filling" logic. Coupled with built-in "zero tracking" and "automatic drop correction," it guarantees that every 1-5kg container meets stringent weight tolerance standards. Operators can execute micro-adjustments for single heads and monitor standard deviations in real-time via the intuitive touchscreen HMI.

High-surfactant materials generate massive foam during high-speed filling. This equipment optimizes physical dynamics to prevent this: the material infeed port is strictly positioned below the minimum liquid level, effectively eliminating foaming caused by material impact. The instant the fill completes, dedicated leak trays or a vacuum suck-back system engage. Along with smooth bottle-clamping plates, these mechanisms completely sever stringing and residual drips, ensuring the conveyor and facility environment remain flawlessly clean.

For North American facilities prioritizing floor-space efficiency, the machine's footprint is critical. This filler adopts an innovative "back-to-back design," integrating 12 highly efficient filling heads into a compact frame. When processing 1.0kg specifications, throughput surges to an impressive 3600 Bottles/Hour; even with maximum 5.0kg containers, it maintains a robust output of 1200 Bottles/Hour. The seamless synchronization of advanced photoelectric sensors and encoders guarantees fluid, highly integrated electromechanical operations.

To pass rigorous cleaning audits, the internal surfaces of the storage tank undergo mirror polishing, tightly controlling surface roughness to Ra≦0.4μm, while the exterior features a premium 2B matte finish. All pipeline openings and tank welding seams utilize advanced flanging techniques for smooth, arc transitions, ensuring a dead-zone-free, easily washable environment. The tank base is engineered with a 3/1000 drainage slope and outfitted with SS316 drain pipes and butterfly valves, ensuring absolute zero residue during product changeover CIP processes.
