Production-Proven Form, Fill & Seal Automation for Dry Powder Inhaler (DPI) Filling Systems
We design and build high-precision Dry Powder Inhaler (DPI) filling automation for global pharmaceutical manufacturers.
Our production lines form blister pockets, micro-dose API powders, and seal strips with clean, contamination-free accuracy — delivering the reliability required for commercial DPI manufacture.
When dose accuracy, sealing integrity, and long-term production stability matter, manufacturers choose our technology.

Clean, Accurate, Metered Micro-Dosing for DPI Blister Strips
Unlike conventional transfer-based filling systems that aerosolise powder, our compression-based rotary blade technology offers high-precision powder dosing for effective API containment, clean sealing surfaces and operator safety.
Our mechanically-controlled filling process helps minimise API loss and powder aerosolisation, delivering reliable, accurately metered doses - critical when handling lactose blends, magnesium stearate additives, and cohesive or electrostatically active APIs.
Result: Clean strips. Accurate doses. Reliable seals.
Doses powder directly into pre-formed blister pockets
Prevents strip surface contamination
Eliminates secondary cleaning operations
Ensures effective heat sealing
Minimises API aerosolisation and waste
Ensures accurate and metered dosing
