Layup molds, vacuum fixtures address aerospace tooling trends

Technical Tooling (Tacoma, Wash., U.S.), showcasing Ravin layup molds and Vacu-Grip vacuum fixtures, demonstrates its alignment with leading trends in advanced aerospace tooling, such as out-of-autoclave (OOA) processing, automation and the integration of additive manufacturing.

Ravin layup molds, developed with advanced granular material and hybrid epoxy systems, deliver the low coefficient of thermal expansion (CTE), high dimensional stability and surface precision features vital for next-generation aerospace structures. Engineered to match the CTE of carbon fiber, Ravin is reported to offer Invar-level accuracy at a fraction of the cost and is suitable for both autoclave (capable up to 350°F, potentially higher for specific applications) and OOA processing.

Manufactured to near-net shape, these molds reduce lead times and waste while supporting rapid prototyping and scalable production. They achieve tolerances of 0.003" or better and surface finishes of RMS 32 or better. Their robust construction enables repeatable, high-precision layups for critical components like lip skins, panels and control surfaces — areas where lightweighting and tight tolerances are essential for performance.  

Vacu-Grip fixtures use advanced vacuum technology to securely hold composite parts during layup, trimming and assembly, minimizing manual intervention and mechanical clamping. Shear holding force is typically more than two times that of v-groove fixtures, providing optimal part stability throughout processing. This not only increases throughput and precision but also supports the trend toward automation and digital integration in aerospace manufacturing. The fixtures’ adaptability for large format and complex geometries aligns with the aerospace sector’s demand for rapid, high-quality production of increasingly intricate composite structures.

According to Technical Tooling, both composite innovations are engineered to meet the aerospace industry’s evolving needs for sustainability, efficiency and high-rate production.
