Micro‑Powder Dosing Accuracy up to ±0.001g

Micro‑powder precise dosing and multi‑component batching are critical processes across pharmaceutical, chemical, electronics and military industries. For high‑value materials with high unit costs, strict filling tolerances and high batch‑to‑batch consistency requirements, material loss, accuracy drift and missing data caused by manual weighing and conventional dosing equipment have long plagued manufacturers.

Specializing in high‑precision on‑line weighing technology, MoveWeigh has developed the WinCK Series micro‑powder dosing & batching equipment, covering standalone dosing units and multi‑station batching systems. Adopting an electromagnetic‑force weighing sensor with scale interval down to 0.1 mg, it delivers maximum dosing accuracy of ±0.001 g. Balancing R&D lab small‑batch testing and mass‑production throughput, it provides an all‑in‑one solution for precise micro‑powder feeding and batching.

01 Three Core Pain Points in Micro‑Powder Feeding & Batching

Pain Point 1: Heavy loss of high‑value materials and poor accuracy control
Raw micro‑powder materials can be extremely costly, with some priced at thousands of currency units per gram. Conventional dosing equipment has limited accuracy: over‑dosing leads to costly material waste, while under‑dosing results in scrapped finished products. Insufficient weighing resolution prevents milligram‑level process control.

Pain Point 2: Poor material adaptability with single‑purpose equipment
Free‑flowing microspheres and crystals suit vibratory feeding, whereas poorly‑flowing powders call for vertical screw feeding. Capacity demands also vary widely: R&D laboratories need small‑batch standalone units, while production floors require dual‑channel and multi‑station parallel operation. Most commercially‑available machines feature fixed feeding modes and station counts, resulting in time‑consuming re‑configuration, change‑over downtime and production losses.

Pain Point 3: Difficult process traceability and compliance audit barriers
Pharmaceutical regulatory inspections and audits demand full‑process records for batching and filling. Manual weighing with hand‑written logs is prone to omissions and human error. Ordinary equipment lacks automatic rejection and data‑logging functions; non‑conforming products risk mixing into finished batches. Furthermore, they cannot interface with digital management systems such as MES and LIMS, failing to meet modern production compliance standards.

02 Four Models Tailored for Diverse Materials and Operating Conditions

WinCK9918MFR｜18‑Station Automatic Tray Loading, Independent OK/NG Buffering

The WinCK9918MFR micro‑powder dosing feeder is designed for poorly‑flowing powders. It combines vertical‑screw feeding with high‑precision electromagnetic‑force weighing, offering 5 g capacity and accuracy of ±0.001~0.01 g. It is a representative unit for small‑batch high‑precision micro‑powder dosing.

Eighteen rotating stations enable automatic tray loading and unloading, plus automatic rejection of NG (non‑conforming) parts. Conforming and non‑conforming products are collected into separate buffers. An independent refill hopper prevents feed interruption. Every tray undergoes weight re‑verification for full traceability. Suitable for high‑value micro‑powder processing in chemical, electronic, pharmaceutical and military applications.

WinCK900MFR｜Vibratory Dosing Direct‑to‑Test‑Tube, Quick‑Release Hopper for Easy Cleaning

The WinCK900MFR vibratory dosing feeder features electromagnetic‑force weighing with 0.1 mg scale interval and maximum dosing accuracy of ±0.001 g. Built‑in automatic calibration sustains long‑term stable accuracy.

Gentle single‑channel vibratory feeding avoids material compression. Servo‑driven vertical movement allows direct filling into test tubes, cryovials and other miniature containers. Quick‑detachable hoppers simplify cleaning and material change‑over. Ideal for free‑flowing powders such as microspheres and crystals; widely deployed in automotive component, electronics, pharmaceutical and military sectors.

WinCK9002MFR｜Dual‑Channel Parallel Operation, Serial‑Port Output of Weighing Data

The WinCK9002MFR dual‑channel vibratory dosing feeder adopts dual‑channel electromagnetic‑force weighing with scale interval of 0.0001 g and maximum dosing accuracy of ±0.001 g. Dual‑channel parallel processing doubles throughput.

Vibratory feeding is followed by flip‑type discharging for clean material drop‑off. Weighing data can be logged in real‑time and exported via serial port for integration with production‑line traceability systems. Suitable for free‑flowing powders like microspheres and crystals for automotive, electronics, pharmaceutical and military industries.

WinCK9206｜6‑Station Multi‑Material Batching, Per‑Station Weighing Feedback

The WinCK9206 six‑station automatic micro‑batching system targets multi‑material automatic batching scenarios. It has a 500 g capacity with batching accuracy of ±0.005~0.05 g (material‑dependent). Servo‑driven screw feeding plus weighing‑feedback control ensures stable batching cycles.

Each station incorporates hopper‑level weighing to independently monitor feeding status. Optional high‑precision electromagnetic‑force weighing provides re‑verification. Full batching data is traceable. Suited for multi‑component batching of poorly‑flowing powders for chemical, electronic, pharmaceutical and military applications.

03 Core Foundation: WinCK Electromagnetic‑Force Weighing Module

All four models rely on the same self‑developed high‑precision weighing core — the WinCK electromagnetic‑force weighing module. It achieves scale interval as fine as 0.0001 g, with real‑time data storage and output capability, forming the hardware guarantee for ±0.001 g‑grade precise dosing.

04 Diverse Application Scenarios Covering Multiple Industries

• Pharmaceuticals: Micro‑powder precise filling and multi‑component batching, ensuring fill‑weight and batch consistency.

• Chemicals & Electronics: Accurate feeding of microspheres, crystals, oxide powders and other granular‑powder materials.

• Military: Low‑loss quantitative feeding for high‑value special powders.

• R&D Laboratories: Small‑batch precise micro‑sample formulation for fast recipe validation.

05 Making Every Milligram Count

The ±0.001 g specification represents more than a technical parameter — it is MoveWeigh’s quality commitment to customers. The MoveWeigh engineering team focuses on high‑precision weighing; both weighing core modules and full‑machine control software are independently developed. From standalone dosing feeders to multi‑station batching systems, MoveWeigh delivers customized turn‑key solutions for micro‑powder feeding and batching.
