EXPANSIONSERT- thread inserts for expansion anchoring

After-moulding insertion into plastic parts bears many benefits:

  • Shorter injection cycles and thus lower manufacturing costs for plastic components
  • Safe, stress-free anchorage
  • High pull-out and torsion values
  • Any repeated screwing as opposed to self-forming screws

EXPANSIONSERT- thread inserts for expansion anchoring

Universal thread insert for thermoset and thermoplastic components

Technology

The EXPANSIONSERT1 thread insert consists of a cross-slotted basic body with internal thread, which has an external diamond knurl, and an spreader plate.

When the thread insert is installed in the mounting hole, the diamond knurl part is expanded by the spreader plate which is pressed down. As a result, it is anchored in the wall of the hole.

The EXPANSIONSERT 2 thread insert consists of a body with internal thread, which has knurls and undercuts on the circumferential surface. Inside the body, there is an spreader plate that is pressed downwards when the thread insert is installed in the mounting hole. Upon installation, the slotted bottom part of the EXPANSIONSERT 2 is expanded and its cutting rings are anchored in the wall of the mounting hole. The thread insert is thus reliably secured against pull-out and twisting.
