ultrasonic and dielectric welding of textiles - sciencedirect
The sewn and tape-sealed seam had a longer bending length than the welded seam, making it less flexible. Welded seams were found to have a greater load carrying capacity than sewn seams. There was no significant difference in bending length between welded and sewn seams. Table 12.3 summarises the relative performance of the three seam types.
ultrasonic welding - wikipediaUltrasonic welding of thin metallic foils. The sonotrode is rotated along the weld seam.. Ultrasonic welding is an industrial process whereby high-frequency ultrasonic acoustic vibrations are locally applied to work pieces being held together under pressure to create a solid-state weld.It is commonly used for plastics and metals, and especially for joining dissimilar materials.

why etfe is the miracle construction material - thoughtcoETFE (Ethylene Tetrafluoroethylene) is an industrial-strength construction plastic used for exterior cladding since the 1980s. ETFE is strong and lightweight. It is often applied in layers that are welded together around the edges and held by a metal framework. Because it is safer and more adaptable than glass, non-rip ETFE is often used as a ...
search results for 'sewn and welded plastics': - gidieffe.netWhen welding plastics, the interface of the two parts is specially designed to concentrate the melting process. One of the materials usually has a spiked or rounded energy director which contacts the second plastic part. The ultrasonic energy melts the point contact between the parts, creating a joint. sewn and welded plastic cases - cieffe filati
how to weld plastics: a complete guide - acme plasticsWrap foil around the pieces to keep them pressed together, but don’t cover the area that will be welded. Prepare your welder: Preheat the welding gun for a few minutes, setting your welding temperatures in line with the materials to be welded. The temperature typically ranges from 390°F to 570°F.
ultrasonic welding of polymers | springerlinkWeld interface of the plastic parts is welded by high-frequency vibration that produces self-heating and localized melting. The principle characteristic of this method is the existence of phenomena that take place on two varied time scales like the flow of molten plastics about 1 s and the vibration about 10–5 s.
