Today we will talk about how to hem a mesh banner?
Generally speaking, there are two hemming methods for mesh banners, hot air welding and High-frequency welding.
Hot air welding technology improves consistency, quality, and enhanced seam strength to lower production costs, increase production output and decrease welding time.
High-frequency welding (often abbreviated HF or RF welding) is a manufacturing process. We use an electromagnetic field to weld two plastic parts together, and the resulting join can be very strong – often close to the original strength of the materials joined.
