Corner Crimping Machine for Aluminum Frames
Custom pneumatic corner crimping machine for precise joining of aluminum frame profiles, with interchangeable tooling for multiple frame sizes.

Fabrit designed and built a custom pneumatic corner crimping machine for the precise and durable joining of aluminum frame profiles. The new machine replaced a worn-out unit and provided more stable process parameters, improved joint quality and greater production flexibility.
The machine was engineered to generate consistent crimping force while allowing quick adaptation to different frame sizes through an interchangeable tooling system.
Challenge
The previous machine was heavily worn and no longer provided sufficient clamping force, resulting in loose corner joints and inconsistent quality of the finished frames.
The lack of a quick tooling change system also reduced production flexibility and made it difficult to switch efficiently between different frame sizes.
Implemented solution
- Fully pneumatic drive system.
- Stable and repeatable crimping force.
- Machine structure designed for durability and long-term industrial operation.
- Interchangeable die system for fast product changeover.
- Adaptation to multiple aluminum frame sizes.
- Simple machine architecture supporting reliable operation and maintenance.
Results
The new machine improved the consistency and quality of aluminum frame corner joints by providing sufficient and repeatable crimping force.
The interchangeable tooling system increased production flexibility and shortened changeover time when switching between different frame formats.
The new machine also improved process reliability and replaced an ageing piece of equipment with a modern solution designed for long-term use.
