threaded insert soft material

Fast4Plast-Softerfix

SOFTERFIX™ inserts for overmolding or insertion are the solution for obtaining a reusable tapping or threading function in soft materials (thermoplastics, thermosets, wood, etc.).

Key features
  • Reusable tapping that provides constant tension in the assembly
Advantages of SOFTERFIX inserts
  • Endlessly reusable tapping
  • Various designs available, open or blind, to meet application specifications
  • Possibility of applying the screw tightening torque corresponding to the required assembly tension without damaging the plastic material support
  • Reinforced axial mechanical strength thanks to the possibility of adjusting the insertion length of the insert
  • Option to integrate our CRUSHPROOF™ concept, which allows the height of the insert to be adjusted in the tooling during overmolding, thereby preventing any risk of plastic flash.
Consider SOFTERFIX Inserts as an alternative to

Tapping:

  • long and costly process
  • The relaxation of the plastic material causes a release of tension stresses.

Self-tapping screw:

  • The tension force in the assembly varies greatly from one part to another because it depends on a variable friction coefficient for the same torque applied to the screw.
  • The relaxation of the plastic material causes a release of tension stresses.
  • the permissible tensile force is limited
