Simple SummaryContent extracted from patent full text and abstract with AI.

This invention introduces a method and device for joining metal and plastic components using a clinching process. The process involves placing a ring in a mold that matches the component's shape and then using a punch to join the metal and plastic parts, with the plastic enclosing the ring during the process. The invention also covers the resulting joined component.

Use CasesContent extracted from patent full text and abstract with AI.

  • Automotive manufacturing, for lightweight hybrid components
  • Consumer electronics, combining metal frames with plastic casings
  • Appliance manufacturing, for robust yet lightweight parts
  • Aerospace parts, integrating metal and plastic elements
  • Construction of furniture or equipment requiring strong metal-plastic connections

BenefitsContent extracted from patent full text and abstract with AI.

  • Provides a strong and reliable metal-plastic bond without adhesives or heat welding
  • Enables more lightweight structures by effectively combining materials
  • Reduces production costs and process time compared to traditional joining methods
  • Suitable for mass production with consistent quality
  • Prevents damage to heat-sensitive plastics since it does not require high temperature

Patent Abstract

Die Erfindung betrifft ein Verfahren und eine Vorrichtung zur Herstellung einer Metall-Kunststoffverbindung mittels Clinchens sowie ein zugehöriges Bauteil, wobei die Metall-Kunststoffverbindung in Form eines Bauteils aus einem ersten Fügepartner in Form eines Kunststoffes und einem zweiten Fügepartner in Form eines Metalls besteht. Vor dem Fügeprozess wird ein Ring in eine die Geometrie des Bauteils wiedergebende Matrize eingelegt derart, dass die Fügepartner auf dem Ring aufliegen, wobei folgend mittels eines Stempels, welcher sich durch die innere Öffnung des Rings in die Matrize bewegt, der erste und zweite Fügepartner gefügt werden. Der Kunststoff des ersten Fügepartners umschließt dabei während des Fügeprozesses den Ring.
