A Case Study (PoC)
Innovative Thermoplastic Hollow Profile Manufacturing Method Successfully Developed
We successfully completed a proof-of-concept study in collaboration with a leading aerospace customer to develop an advanced manufacturing method for thermoplastic hollow profiles. The objective was to enable the efficient processing of bent hollow profiles using high-performance thermoplastic composite materials. After rigorous development and validation, the proposed manufacturing method was approved by the customer, and the optimized part geometry was delivered.
Project Scope & Work Packages
The study was structured into the following key work packages:
- Project Management & Coordination – Ensuring seamless execution and communication
- Literature Review & Benchmarking – Analyzing existing technologies and best practices
- Material Characterization – Assessing properties of high-performance thermoplastics
- Process Concept Development – Designing an innovative manufacturing approach
- Tool & Equipment Design – Developing specialized manufacturing tools
- Prototyping & Testing – Producing and evaluating sample components
- Documentation & Results Presentation – Delivering a comprehensive project report
The study was successfully completed within six months, achieving a bending capability of more than 10° while ensuring full consolidation of the part, as confirmed by the customer.
This achievement underscores our expertise in advanced composite manufacturing and our commitment to delivering cutting-edge solutions for the aerospace industry.
