Weighing Filling Machine FAQ: Accuracy, Speed and Weight Range
Understanding the precise capabilities of industrial weighing filling machines is essential for selecting the right solution tailored to your production needs. From micro-precision in small-batch tea packaging to high-speed bulk bagging of 25kg agricultural materials, each model within CECLE’s weighing family delivers distinct performance parameters grounded in real-world engineering. This FAQ provides detailed, fact-based answers anchored in actual product specifications, helping buyers make informed decisions based on accuracy, throughput, weight range, material compatibility, and integration potential.
What is the highest precision achievable across your weighing machine models?
The precision of CECLE's weighing machines varies by model and application, with the most advanced combination scales achieving sub-gram accuracy. The TD-10-0.5L and TD-14-0.5L 10-head and 14-head combination scales deliver an average precision of 0.1~1g, making them ideal for high-value materials like specialty coffee beans, premium seeds, or blended seasonings where minimizing over-giving directly impacts profit margins. For smaller-scale operations, the FM-50 model offers a tolerance scope of ±0.2–2g, suitable for precise dosing of tea leaves, nuts, or small hardware parts. Even linear scales such as the TD-2M and TD-4M maintain consistent accuracy within 1~2g across their respective ranges. These figures are derived from official technical parameters and reflect real-world performance under standard operating conditions.
How fast can these machines process filled bags per minute?
Packing speed depends heavily on the machine type, weight range, and material characteristics. The TD-2M dual-head linear weigher operates at 30 times/min, while its 4-head counterpart, the TD-4M, maintains the same cycle rate despite having more feeding units—efficiency is balanced through intelligent alternation and control algorithms. For high-throughput applications, the TD-10-0.5L and TD-14-0.5L combination scales reach up to 60 bags/min, leveraging rapid permutation calculations across 10 or 14 hoppers to match high-speed VFFS packing machines. Meanwhile, the FM-50 series runs at 6–12 bags/min, optimized for low-volume, high-accuracy tasks like lab-scale dispensing or e-commerce fulfillment. The A-25 bulk bagging scale, designed for heavy-duty output, processes 5–7 bags/min, reflecting the mechanical constraints of handling 25kg (55.1 lbs) loads per discharge.
What is the minimum and maximum weight range supported by your equipment?
CECLE’s weighing solutions span a broad spectrum to accommodate diverse applications. The FM-50 model handles ultra-light fills with a range of 1–50g, making it perfect for tea, powdered supplements, or small electronic components. In contrast, the FM-9999 model supports weights from 100–9999g (0.22–22 lb), enabling single-dose packaging of large consumer or industrial quantities like sugar sacks or fertilizer bags. Linear scales like the TD-2M and TD-4M cover 20–2000g, suitable for mid-sized food items such as snack packs or spice blends. Combination scales offer narrower but highly precise ranges: the TD-10-0.5L weighs 50–1000g, while the TD-14-0.5L extends to 50–2000g, allowing flexibility across both medium and larger package sizes. Each model’s range is explicitly defined in its technical documentation and validated during factory testing.
Can these machines handle both powders and granules, or are they limited to one material type?
Material compatibility varies significantly by model. The TD-2M and TD-4M linear weighers are best suited for granules, small chunks, and free-flowing coarse powders such as rice, salt, sesame, MSG, and milk powder. However, they are not recommended for ultra-fine or dusty powders due to potential flow issues and static buildup. For such materials, CECLE recommends pairing the TD-2M with a screw (auger) metering system or using dedicated auger fillers instead. Conversely, the FM-50 and FM-9999 series are engineered for both granular and powdered materials—including tea leaves, spices, plastic pellets, and small hardware—thanks to their stepless vibrating feeders that prevent clogging. The TD-10-0.5L and TD-14-0.5L combination scales also perform well with fine granules and powders, provided the particles are non-sticky and have consistent density. Always verify material characteristics before finalizing selection.
Is it possible to mix multiple materials in a single weighing cycle?
Yes, several models support multi-material mixing in a single discharge. The TD-4M 4-head linear weigher enables proportional mixed weighing of different ingredients via independent target weight settings—ideal for products like "mixed grains" or "trail mix." Similarly, the TD-10-0.5L and TD-14-0.5L combination scales feature powerful mixed batching functions, allowing users to define recipes involving two or more materials. The 14-head configuration of the TD-14-0.5L even allows zoning of hoppers into separate material groups, enabling complex blends such as eight-treasure porridge mix or custom nut assortments without manual intervention. The A-25 semi-auto bulk bagging scale also includes mixed batching functionality, letting operators set precise ratios for combining fertilizers, feeds, or seed mixes. All settings are stored and recalled via the smart control panel, ensuring repeatable accuracy across batches.
How do these weighing machines interface with packaging systems like VFFS or automatic baggers?
Integration is seamless across all major models. The TD-2M and TD-4M can be connected to a VFFS packing machine via a digital signal from the control panel, allowing automatic triggering upon reaching target weight—eliminating manual bag placement. The FM-50 series uses a foot pedal for discharge, but can be linked to automated lines through optional sensor inputs. The TD-10-0.5L and TD-14-0.5L are designed as core components of fully automated lines, often paired with Z-type bucket elevators and working platforms to feed directly into vertical form-fill-seal (VFFS) machines. The A-25 bulk bagging scale includes a conveyor belt that transports filled bags automatically to a sewing station, reducing labor intensity. Additionally, the TD-1C1 dynamic checkweigher integrates at the end of any line, detecting under/overweight packages and triggering rejection mechanisms—making it a vital quality gate when paired with combination scales or wide-range fillers. Full integration options are detailed in the operational manuals for each model.
What are the key differences between your linear weighers and combination scales?
The fundamental difference lies in weighing logic and application. Linear weighers like the TD-2M and TD-4M use a stepless vibratory feeder to transport material into one or more hoppers, stopping precisely when the target weight is reached. They are cost-effective for moderate speeds (up to 30 bags/min) and simple, consistent materials. In contrast, combination scales such as the TD-10-0.5L and TD-14-0.5L employ a computerized algorithm that evaluates all possible combinations of 10 or 14 hoppers simultaneously, selecting the optimal mix to hit the target weight with minimal error. This results in superior precision (0.1–1g) and higher speeds (up to 60 bags/min), especially beneficial for high-value or variable-weight products. While linear scales excel in simplicity and lower upfront cost, combination scales represent the gold standard for automation and efficiency in mid-to-large-scale food and agricultural processing.
