Learn More About Heat Sealing
In its basic definition, heat sealing is the process of joining thermoplastic materials through the application of heat and pressure. As with all thermoplastic processing, heat sealing requires controlling three distinct variables: HEAT, TIME, and PRESSURE. Failure to control any of these variables can result in poor quality welds that peel or tear in use.
Common Types of Heat Sealing:
Ultrasonic: Ultrasonic welding uses high frequency sound waves to produce heat by localized vibration. Parts are typically held together in a jig while they are heated creating the necessary pressure. Ultrasonic welding is typically used as a replacement to adhesives and solvents.
