Hot air welding is a heat sealing process that applies heat and pressure to multiple material pieces, either through a rotary press or manually, in order to form a permanent seam between them. The seal is permanent and resistant to air and water pressure. This particular sealing process is ideal for fabricating products or improving their functionality, as the resulting bond is stronger than the original materials used in fabrication.
Benefits of Hot Air Welding vs. Other Heat Sealing Processes
Compared to radio frequency welding, hot air sealing takes less time, and it is a good sealing process to use in the fabrication of three-dimensional products. It also requires no tooling or dies. However, like hot wedge sealing, it can only seal two surfaces at a time.
In addition to the increased speed, the hot air sealing process is useful for sealing a larger number of materials than other sealing processes. It can form long and continuous panels, making it ideal for larger products, especially containment and inflatable products, or products that require curved seams.
Along with hot wedge welding, hot air welding is a heat sealing process that works well for freehand-style sealing because of its ability to adapt to the specific maneuverability and approach of the bonded materials. The main difference between the hot wedge welding and hot air welding processes is that hot wedge sealing requires a wedge in the heating process, while hot air welding doesn’t.
Create Stronger Tear-Proof Seams
Hot air welding forms a strong watertight and airtight seam that is potentially stronger than the welded materials, helping to maximize the longevity of products. With this heat sealing process in their fabrication, products across a large number of industries will be able to withstand wear and tear over long periods of use. Many industries rely on hot air welding in the construction of their products because of the seals it forms.
A few of the many products that use this heat sealing process include:
- Fluid containment bags for the medical industry
- Pre-conditioned air hoses for temperature control in military aircraft
- Industrial curtain walls for protecting manufacturing plant workers and equipment
- Watertight weapon containment bags for government applications
