For a client operating in the ammunition industry, Fabrit designed and delivered a fully pneumatic automatic primer inserting machine for cartridge cases.

The objective of the project was to replace a manual pressing process with an automated solution ensuring consistent product quality, integrated quality control, and safe operation in explosion-hazardous environments.

The project included the complete mechanical design of the machine and its adaptation for operation in areas with explosion risk.

Previously, primer insertion was performed using a manual press. This resulted in:

• limited production efficiency,

• quality dependent on operator performance,

• lack of automated process control,

• risk of incorrect primer seating,

• inconsistent insertion parameters.

The client required an automated solution capable of ensuring:

• repeatable and stable product quality,

• automatic verification of primer seating depth,

• controlled and standardized crimping process,

• safe operation in explosion-prone environments.

Fabrit was responsible for:

• development of the technological concept,

• full mechanical design of the machine,

• integration of pneumatic systems,

• implementation of an automatic quality control system,

• adaptation of the machine for operation in explosion-hazardous areas,

• assembly, commissioning, and process optimization.

The designed machine automatically performs all critical operations within the primer insertion process:

• pressing the primer into the cartridge case,

• performing the crimping operation,

• measuring and verifying primer seating depth,

• applying lacquer around the crimp circumference.

The machine is fully pneumatic, ensuring safe operation in explosion-hazardous environments. The design guarantees stable process parameters and high repeatability, independent of operator influence.

• full automation of the primer insertion process,

• significantly improved product consistency and quality,

• integrated verification of correct primer seating depth,

• reduced dependency on manual operation,

• enhanced operational safety,

• compliance with requirements for explosion-hazardous environments.
