While volumetric feeders offer cost-effective solutions for standard applications, loss-in-weight scales deliver the precision required for high-value, tight-tolerance extrusion processes—making both systems critical tools in the modern plastic processing facility.
The volumetric feeder is suitable for most extruder feeding solutions, it has low-cost and high-efficiency feeding characteristics. As the most widely used feeding system for general extrusion applications, volumetric feeders balance affordability with reliable performance, making them ideal for small to mid-sized manufacturers processing non-critical materials (e.g., general purpose PE/PP, rigid PVC compounds) where precise dosing is not a primary requirement.
Unlike loss-in-weight scales that measure material weight in real-time, volumetric feeders deliver a consistent volume of material to the extruder—controlled by screw rotation speed and screw geometry. This simplicity translates to lower upfront costs (30-50% less than loss-in-weight systems) and minimal maintenance, making volumetric feeders a practical choice for high-volume, low-margin production runs.
The volumetric feeder consists of a small twin screw, barela, and motor Mea Hana Mīkini Filler Masterbatch engineered for reliable material flow and minimal downtime. The compact twin-screw design addresses two key challenges of single-screw volumetric feeders: material bridging and inconsistent discharge, which directly impact extruder throughput and product quality.
When the material enters the barrel, the screw is simply rotated by the stirring roller, which not only pushes the material to the bottom, but also reduces clogging, making it easier to discharge, saving time and energy, and solving the problem of slow discharging affecting productivity. The intermeshing twin screws create a positive displacement action, ensuring that material is consistently conveyed to the extruder feed throat—even for materials with poor flow characteristics (e.g., regrind flakes, pelletized PVC with high filler content).
Key design features of Zhuoyue’s volumetric feeders include:

Zhuoyue’s volumetric feeders handle a broad range of plastic materials, including:
While volumetric feeders excel in cost-effective, standard applications, Hale Hana Mīkini Filler Masterbatch Loss-In-Weight (KULA) scale metering feeders are engineered for precision dosing—essential for high-value extrusion processes where material consistency directly impacts product performance, regulatory compliance, or production yield.

With dosing accuracy of ±0.1% and repeatability of ±0.05%, LIW feeders ensure consistent material input to the extruder—critical for:
Third-party testing by the International Society of Automation (ISA) confirms that Zhuoyue’s LIW feeders maintain precision even with material bulk density variations of up to 15%—a common issue with recycled or filled plastics.
Precision dosing eliminates over-feeding (a common issue with volumetric feeders), reducing material waste by 3-5% per production run. For high-value materials (e.g., medical-grade TPU at $5/kg), this translates to annual cost savings of $50,000-$150,000 for a 24/7 production facility.
Built-in data logging and audit trails make LIW feeders ideal for regulated industries. All dosing parameters (setpoint, actual rate, material type, operator ID) are recorded and can be exported to CSV/PDF format for regulatory inspections—critical for FDA 21 Mahele CFR 11 hoʻokō (electronic records/signatures) in medical device manufacturing.
Consistent material feeding stabilizes the entire extrusion process, reducing variation in melt pressure, temperature, and product dimensions. This results in:
