Advances in bonding, welding, joining and fastening will be explained in greater depth at Eureka’s ‘Joining Technologies’ Design Day next month

Captive fastener snaps to it

Dirak has brought out a captive fastener that uses its D-Snap technology to allow it to be installed in a moment in suitably stamped cut-outs

Time for a little bonding

Two techniques developed at Fraunhofer Institutes could lead to stronger glasses that are made more quickly and cheaply. Lou Reade reports

U clamps the key to rapid scaffolding

Ingenious screw-up ‘U’ element clamps, are key to the success of the Lobo Systems method of quickly erecting scaffolding, platforms and temporary structures

Gripping solutions

A hand clamp is able to grip hard with a 500N holding force, because it combines both screw and wedge actions

Join together

Tom Shelley reports on a technique similar to adhesive bonding that will join dissimilar materials to one another
