Highly wear-resistant thread inserts for in-molding

IMTEC® refers to the „In-Moulding TEChnology“ and describes the in-molding of metal thread inserts with plastics before ejection.


IMTEC® – The joining solution for the in-molding technology

  • Inserting of wear-free and resilient metal threads in high-quality plastics
  • Generation of blind hole threads or through hole threads, depending on customer components
  • Combining specific advantages of the different materials
  • Plastic-metal components provide for advantages such as reduced weight, improved corrosion resistance and component cleanliness
  • IMTEC® molded inserts are particularly suitable for thermoset and thermoplastic materials


Component cleanliness, weight reduction, improved corrosion protection

In many fields of application, in-molding of metal fasteners with plastics is the solution.

IMTEC® molded inserts are benefiting of the advantageous synergy effect of high strength metals in combination with plastics.

IMTEC® molded inserts are placed into the mold manually or by means of a handling system. Only the core pins of the injection mold have to be geometrically adapted to the IMTEC® molded inserts.

Product types



Thread inserts of asymmetric rolled stainless steel A2, which is coiled to a fixed bushing with one flange-type extension.

  • Magnetic despite of stainless steel: Magnetisation of components due to the forming process and therefore fixation on the core pin
  • Residual dirt minimization
  • Weight reduction of the component
  • Maximum usable thread length



Thread inserts with “double flange” produced from steel by cold forming.

  • Deformation area allows precisely adjusting of the thread inserts length according to the mold dimension
  • No metal-cutting operation
  • Very large flange diameters possible

Our IMTEC® product catalogue provides more information about our thread inserts.
