SPREDSERT® For thermoplastic components

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

The SPREDSERT® 1 is inserted into the mounting hole until the retaining flange is completely anchored in the plastic material. In that process, the slotted area is compressed. The radially secured SPREDSERT® 1 is expanded by the screw so that the anchor rings penetratethe plastic material and ensure the tight-fit of the thread insert. In this process, the screw is locked. For the additional expansion force, the tightening torque must be increased by 10 %.

 

The SPREDSERT® 2 is inserted into the mounting hole until the retaining flange is completely anchored in the plastic material. In that process, the slotted area is compressed. The radially secured SPREDSERT® 2 is expanded by the screw so that the diamond knurling penetrates the plastic material and ensures the tight-fit of the thread insert. In this process, the screw is locked.

For the additional expansion force, the tightening torque must be increased by 10 %.

 

The SPREDSERT® with retaining flange is inserted into the through hole until the retaining flange is seated. The slotted anchoring section with diamond knurl is compressed.

By screwing in the screw, the thread insert is forced open in the anchoring section so that the diamond knurling penetrates the plastic material. The retaining flange which acts as a shoulder support ensures high pull-out locking while the screw is also locked.

For the additional expansion force, the tightening torque must be increased by 10 %.
