Double Diaphragm Forming (DDF)

Create a complex composite part in under 5 minutes

Syensqo's novel forming technology, Double Diaphragm Forming (DDF), is now a proven and established method, having been successfully commercialized and adopted by customers.. This method automates dry fiber pre-forming, prepreg pre-forming or press molding into a single-step process speeding up the takt time involved in part making. The DDF technology also cuts down on labor cost and processing time due to the two diaphragm layers preventing the need for tool preparation and cool down between moldings. The diaphragm itself can act as a protective layer for painting and bonding operations.

This new technology is easy to implement as it can be seamlessly integrated to your existing press infrastructure. The DDF technology has already proven its capabilities in part quality, process accuracy and repeatability. Syensqo has scaled up the process for industrialization readiness by installing and demonstrating an automated pilot production line at its Heanor, UK facility. This set up enables a highly automated process.with a takt time of under five minutes.

Key Benefits:

  • Single-step molding process reducing takt and cycle times

  • Accurately form complex 3D shapes while minimizing chances of defects

  • Fully automated process compatible with hot compression molding

  • Eliminates the need for tool cleaning or releasing and less prone to contamination

  • Highly versatile for various high-volume applications

  • Chemically inert parts until removal of Syensqo films


Typical Applications:

Serial production of structural components, up to 50,000 per year from a single manufacturing line. Successfully demonstrated on:

  1. Regular and low tack prepregs

  2. Fast and slow cure prepregs

  3. Structural aerospace grades

  4. Woven and NCF reinforcements with binder for RTM/HP-RTM preforms
