Aerospace Solutions for Mission-Critical Components
The aerospace industry depends on metal castings and machined housings that meet stringent performance criteria, including under extreme thermal, mechanical, and environmental loads. Even minor porosity in metal aerospace parts can reduce pressure retention, compromise fluid integrity, and shorten service life.
Godfrey & Wing’s vacuum impregnation technology gives aerospace manufacturers a proven means of addressing porosity. By sealing leak paths, vacuum impregnation improves the integrity of critical parts and helps manufacturers heed strict standards for performance and reliability.
Porosity Challenges in Aerospace Components
Porosity affects a wide range of metals. Micro-void paths directly impact fuel, hydraulic, environmental control, and other key systems, giving engineers a strong interest in addressing:
- Voids in castings that compromise pressure boundaries
- Machining-exposed porosity that creates leak paths
- Performance issues that can arise as fluids or air ingress into sealed systems
Porosity can ultimately undermine mission readiness and shorten component life. Using vacuum impregnation allows engineers to enable leak-free performance.
How Godfrey & Wing’s Vacuum Impregnation Works
Our tightly controlled, closed-loop impregnation workflow seals internal porosity without negatively impacting dimensional characteristics or surface finishes. The process also integrates directly into existing manufacturing lines, supporting the aerospace industry’s need for serialized, high-accountability production.
Vacuum impregnation relies on a repeatable sequence:
- Loading parts into a vacuum chamber
- Introducing sealant under controlled vacuum followed by pressure to penetrate micro-voids
- Cleaning and rinsing parts to remove all residual sealant
- The sealant is cured and forms a permanent polymerized barrier
- Drying finished parts, cataloging them for inventory control and traceability standards
Applications in Aerospace Manufacturing
By sealing leak paths, our vacuum impregnation process improves aerospace component integrity in a range of critical components. This is of special importance as part complexity and weight-reduction initiatives rise industry-wide.
Aerospace OEMs and Tier 1 suppliers can also integrate vacuum impregnation into manufacturing processes for the following:
- Hydraulic and fuel systems
- Engine components
- Electronic housings and powdered metal components
- Thin-wall lightweight housings for next-gen aircraft
To help manufacturers bring new flight-critical components online without production delays, Godfrey & Wing also offers vacuum impregnation services to support qualification programs, PPAP validation, and NADCAP-aligned quality controls according to your specific requirements.
Benefits of Vacuum Impregnation for Aerospace Components
Aerospace programs must leverage each available advantage to ensure part durability, system integrity, and lifecycle efficiency. Vacuum impregnation delivers measurable improvements in long-term performance and cost, with key benefits that include:
- Enhanced reliability under extreme operating conditions
- Leak-free performance and protection for fuel, hydraulic, and cooling circuits
- Lower maintenance and lifecycle expenses
These improvements give aerospace firms a dependable, repeatable method for addressing porosity, helping engineering teams meet high standards for a wide range of aerospace components and materials.
