High speed: The high performance machine for producing partially filled blisters (intermittent)


The HSP forms, fills and seals up to 2520 blister cups per minute. Six drum filler dosing units are used for filling. Camera inspection systems ensure that the cups are filled and the blister web is sealed. Serial numbers are printed at regular intervals. The blister web is then cut into individual pieces.

  • Separate production area with good accessibility
  • Integrated containment for operator protection when processing highly efficient and toxic products
  • Reliable inspection systems, in-process inspection of fill quantities
  • Continuous powder feed with connected containers
  • Modular construction with minimal setup space
  • Detection and marking of improperly filled blisters
Blister production and powder dosing with the HSP

This HSP production machine produces DPI blister strips and fills them with powder at the 6-part dosing station “Multi-dose 6”.

Powder dosing via roller dosing unit

Six roller dosing units serve to microdose powder into the blister strips.

Machine features

Powder for inhaler production can be dosed in minimal quantities using the roller dosing method.


For injection and inhalation products, micro-dosing of liquid or powder ingredients is an integral part of the overall process. A variety of dosing systems are used depending on the task at hand.

Powder filling of inhaler blisters

Filling blisters

The powder filling module that is completely integrated into the machine can be optionally equipped with a drum filler or with a diaphragm filler. For roller dosing, the cavities are partially filled, for diaphragm dosing, the blister cups are filled up to 100%.

Protection by way of barrier technology and containment

Barrier technology

Compact machine design and detailed knowledge of all processes makes Harro Höfliger a specialist in containment and barrier systems that serve to protect both the operator and the product. For ideal accessibility, ergonomic studies are performed that simulate all processes and operating steps.

Inspection with x-ray technology


The in-line system performs a destruction-free inspection of weights in the blister strips using x-ray technology. An analysis is done within the tolerance range by matching the gray values. An effective application is guaranteed with the complete inspection of the running processes (PRT), allowing quick batch release.
