Mconvey client of this case is a renowned European manufacturer of watch batteries, supplying micro lithium cells to premium European watch brands.
As requirements for color consistency and batch stability of lithium battery packaging film increase, accurate gravimetric powder dosing and stable material feeding have become increasingly important. To meet the customer’s production needs, Mconvey provides accurate Twin Screw Feeder technology, covering dosing, weighing and control for ultra-fine powder handling.
Key Challenges in Ultra-Fine Pigment Dosing
- Poor powder flow & inconsistent feeding: Ultra-fine pigments tend to bridge and arch inside hoppers, causing discontinuous material flow and unstable dosing.
- Agitation-induced weighing disturbance: Stirring in conventional equipment interferes with weighing,in inconsistent color from batch to batch.
- Difficult residue removal & longer changeover: Powder residue makes cleaning more difficult and increases the risk of cross-contamination between pigments.
- Manual feeding errors & formulation deviations: Manual feeding is prone to operator-related errors, increasing formulation deviations and rework risks.
Solution: Mconvey Twin Screw Feeder for Gravimetric Powder Dosing
High-Precision Gravimetric Powder Dosing to Meet Formulation Requirements
Made of 304 stainless steel with a 20L hopper to meet clean production requirements. This twin screw feeder enables precise gravimetric powder dosing for pigments and additives at preset ratios, achieving an accuracy of ±0.1% of setpoint.
Smart Control for Easy Formulation Management
PLC + touchscreen control with a simple, intuitive interface for visualized parameters and one-click recipe management. Self-learning control optimizes the gravimetric powder dosing process and enables recipe changes without manual adjustment, improving production efficiency.
Self-Cleaning Twin-Screw for Stable Powder Feeding
The self-cleaning twin-screw design enables fast material changeover with minimal residue in the feeding path. 360° dead-zone-free anti-bridging technology ensures smooth, continuous feeding of even poorly flowing powders.
Patented Weighing Design, Reduced Agitation Interference
The patented design eliminates interference from agitation during weighing, keeping the gravimetric powder dosing weighing system stable and accurate throughout the dosing process.
Compact and Flexible Installation
With a compact and simple design, this twin screw loss-in-weight feeder can be flexibly installed to fit different production layouts and applications.
For high-end lithium battery packaging film production, stable gravimetric powder dosing is essential for formulation control and product consistency.
Mconvey continues to develop custom gravimetric powder dosing systems and twin screw feeder solutions tailored to powder characteristics and process requirements, delivering practical production solutions.
