Expert Application Engineering
Advanced Seals for Demanding Applications
Aerospace and Defense sealing systems are designed to efficiently transfer energy, keep fluids in, contaminants out, and prevent components from wearing out in harsh environments.
Seals can be one component all the way up to multiple components and materials. However, most seals rely on elastomer contacting the hardware or plastic contacting the hardware. More information on the types of seals we offer is available on our interactive catalog.
Metal Strength at a Fraction of the Weight
Greene Tweed has a long history of developing high-performance thermoplastic and composite components for a broad range of critical Aerospace and Defense applications, using PAEK or other high-end thermoplastic matrix materials.
Greene Tweed thermoplastic and composite structural components benefits include:
- Lightweight, high-performance alternative to metal parts, components, and assemblies
- Reduced part complexity and cost by combining multiple assembled components into one molded part
- Superior strength-to-weight ratio in demanding environments
