Metal Hook and Loop Fastener Tapes

Up and close on velcro® more than 60 years ago, the swiss engineer and inventor george de mestral was trying to painstakingly remove burrs from his dog’s coat after a hunting excursion, he stumbled on an ingenious idea. based on the model he had observed in nature, he constructed a fastener from numerous small hooks and loops, which he subsequently named velcro®. unfortunately, standard synthetic hook and loop fasteners are not very resistant to heat and aggressive chemicals.

Car parked in direct sunlight can reach temperatures of 80 °C, and temperatures of several hundred degrees centigrade can arise around the exhaust manifold. aggressive disinfectants are used for cleaning purposes in hospitals, and traditional hook, and loop fasteners are too weak for use in the construction of building façades…temperatures in excess and aggressive chemical solutions do not pose any problem for Metal Hook and Loop Tapes, which also offers adhesive strength of up to 35 tonnes per square meter when tensile force is applied parallel to the fastener surface. when it is applied perpendicular to the fastener surface, Metal Hook and Loop Tapes can still withstand a force of seven tonnes per square meter, and, like a standard velcro® fastener, it can be opened and closed without the help of any tools.

Hook and loop fasteners have become commonplace features of both industry and households. however, they have one snag: they are too weak for many applications.hook and loop fasteners made of spring steel have now been developed at the institute of metal forming and casting.

The device consists of hook tape and loop tape 0.2 mm thick. these fasteners are resistant to chemicals and can withstand a tensile load of up to 35 tonnes per square meter at temperatures as high as 800°C.

Spring steel hook elements deform elastically under light pressure to glide into openings in a perforated tape, once inserted, they return to their original form and resist back pull like an expanding rivet. numerous steel hooks can attach at any angle to the loops in the perforated metal loop tape.

Like velcro fasteners, Metal Hook and Loop Fastener Tapes devices can be easy to secure and release, yet they can withstand very strong mechanical stresses, high temperatures and harsh chemicals. the unbeatable advantage of this hook and loop fastener is that it is easy to close and open again, the principle therefore is put to a very wide range of uses, for example air-conditioning and ventilation systems in building services engineering and automotive construction.
