ELECTRIC CARTRIDGE HEAT METHOD
- 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
- Individual heat block control with thermocouple feedback
- Heat remains constant during release of assembly
- Improved consistency of part dimensions
- Accelerate chemical reaction
- Improve adhesive characteristics
- Easier to understand/maintain
- Little day-to-day variation
