MoveWeigh ±0.001g Vial Filling Accuracy, Making Every Milligram Count

Filling lyophilized particles, biological reagents and high-value granular pharmaceuticals has always been an unavoidable key process in pharmaceutical production. High raw material costs, strict filling tolerance standards, difficulties in GMP-compliant data traceability and limited production efficiency bring persistent material loss and quality risks for pharmaceutical and IVD enterprises relying on manual filling or low-end equipment.

Specializing in high-precision in-line weighing, MoveWeigh launches the WinCK series automatic vial filling machines. The portfolio includes single-channel and four-channel models with optional vibratory or screw feeding. Delivering a maximum filling accuracy of ±0.001g with milligram-level precision, the machines meet both lab-scale trial production and mass manufacturing demands, providing an all-in-one solution to resolve all pain points in automatic granular vial filling.

01 Three Core Industry Pain Points of Granular Vial Filling

Pain Point 1: Massive Material Loss Caused by Weighing Deviations

Raw materials such as lyophilized biological particles, antibodies and trace diagnostic reagents come with extremely high costs, with some varieties costing thousands of RMB per gram. Traditional filling equipment only reaches an accuracy of ±0.1g. Overfilling leads to costly raw material waste, while underfilling results in fully rejected finished products, generating staggering cumulative losses during mass production. Conventional weighing equipment features insufficient resolution and fails to realize precise micro-quantity control.

Pain Point 2: Poor Compatibility of Single-Type Equipment for Diverse Material Properties

Fragile, loose particles are prone to extrusion and breakage under screw feeding, while low-flow powders suffer unstable dosing with vibratory feeding alone. Besides, manufacturers have differentiated production requirements: R&D laboratories only need low-output single-channel machines, whereas mass production workshops demand high-speed multi-channel synchronous operation. Most mainstream equipment features fixed channel quantities and feeding modes, requiring tedious parameter adjustment during material or vial size changeovers and causing costly production downtime.

Pain Point 3: Barriers to GMP-Compliant Production Traceability

Pharmaceutical factory inspections and audits impose strict requirements on full-process filling records. Manual handwritten records are prone to omission and errors. Ordinary equipment lacks functions for out-of-tolerance rejection and real-time data storage, allowing non-conforming vials to mix into finished goods and creating severe quality hazards. Without standardized data communication interfaces, such devices cannot connect to MES systems, failing to meet digital management standards for modern pharmaceutical plants.

02 WinCK Series Automatic Vial Filling Machines: Targeted Solutions to All Filling Challenges

Core Advantage 1: Dual Weighing Modes for Milligram-Level Precise Dosing Down to ±0.001g

Equipped with self-developed high-speed sampling technology and dynamic filtering weighing algorithms, as well as high-precision weighing sensors with an electromagnetic force resolution as low as 0.1mg, the machine supports two interchangeable weighing modes:

1. Weighing bowl filling: Stable accuracy of ±0.01g, ideal for mass production of standard particles;

2. Direct under-vial filling weighing: Weighing resolution of 0.0001g, with an ultimate filling accuracy of ±0.001g to minimize waste of high-value trace materials.
The system dynamically adjusts feeding volume in real time after each dosing cycle to stabilize filling weight for every vial and eliminate expensive raw material waste at the source.

Core Advantage 2: Diversified Machine Models & Multi-Channel Feeding for Full-Scenario Production

A full lineup of customizable models caters to different output and material handling needs:

• WinCK9001: Single-channel vibratory feeder. Gentle feeding avoids extrusion and particle breakage, perfect for small-batch R&D trials;

• WinCK9201: Single-channel screw feeder, delivering stable dosing for poor-flow, agglomeration-prone powders;

• WinCK9004: Four-channel vibratory filling machine with a maximum throughput of 1,200 vials per hour (300 vials per hour per channel), the flagship model for mass manufacturing.

Vibratory feeding fully preserves original particle integrity, while screw feeding handles special powders. Customers can select feeding modes based on their unique material characteristics.
Compatible with mainstream vial specifications of 5mL, 7mL, 10mL and 15mL, the machine covers a filling weight range of 0~6g, suiting both laboratory small trials and full-scale workshop production.

Core Advantage 3: Fully Automatic Production Line with Siemens PLC & Multi-Layer Error Prevention to Cut Manual Labor

The machine adopts Siemens S7-1200 series PLC control system paired with a 10-inch Weinview color touchscreen for intuitive visual operation.
Complete automatic workflow: Automatic vial feeding → In-line weighing → Quantitative filling → Stopper feeding → Stopper pressing. An optional automatic capping machine can be connected to integrate seamlessly into the complete vial packaging line.
Multi-layer error prevention functions: Automatic rejection of tilted vials, stopper pressing interlock for empty feeders, and diversion of out-of-tolerance materials into a dedicated NG hopper. Non-conforming products are discharged through an independent NG channel, allowing reclamation and reuse of rejected materials to eliminate raw material waste.
With a compact footprint, the machine can operate standalone or be integrated into existing packaging lines with minimal renovation costs.

Core Advantage 4: Full Lifecycle Data Traceability to Meet GMP Audit Standards

The machine locally stores filling weight data for every single vial and supports data output via Ethernet Modbus TCP protocol, enabling seamless integration with enterprise MES and LIMS digital management systems.
All data including individual vial filling weight, production timestamp, channel number and pass/fail status is permanently archived, providing solid documentation for audits and regulatory inspections and resolving compliance risks caused by incomplete or unreliable manual records.
