FDS® Product Animation

With EJOT FDS®, joining processes are faster and more efficient because work steps such as pre-drilling or pre-punching are no longer necessary. Through the optimisation of the fastener layout, the joining of a body-in-white in space frame structure can be carried-out completely without pre-drilling. Here, the fastening parameters, where adjusted, and the geometry of the FDS® screw below the screw head are optimised, to accommodate the small amount of the material that flows against the fastening direction. It is a design that means the clearance hole no longer needs to take up the displaced material as this is now absorbed by the increased space below the FDS® screw head. It is a six-stage process – warming up, penetration of the material, forming of the through draught, thread forming, full thread engagement and tightening.
