CURING SYSTEM
- Reasons for external heat
- Accelerate chemical reaction
- Improve adhesive characteristics
- Application of heat
- Controlled temp. – 200-375F -93-190C
- Confined positioning – to the adhesive area
- Removal of heat before release of assembly
- Robust Process

HOT AIR IMPINGEMENT
- Low pressure air 2-5 psi
- Distribution through stainless steel pipes
- Low inertia electric heater
- Manifold distribution system
- Flow control balancing valve
- Air jets directed at bond lines
- Air jets encapsulated in support fixtures
ADVANTAGES of HOT AIR IMPINGEMENT SYSTEM
- Air jets give good heat transfer – faster cycle times; direct contact with part not required
- Heat from one or two sides
- Dissimilar materials can be bonded
- Fixtures stay cooler – cut to math data
- Assemblies can be cooled in the fixture
- Easier to understand/maintain
- Little day-to-day variation
