Abstract
The invention relates to a method for producing a connection between a first plastic component and a second plastic component, wherein at least one of the two components is produced by plastics injection moulding, wherein at least one fastening region is provided on the at least one component and is moulded with a surface structure of grooves having a small spacing, and wherein the components are connected to one another by an ultrasonic welding method in the fastening region.
Claims13
A method for producing a connection between a first component and a second component, comprising:
- producing at least one of the first and second components by plastics injection moulding;
- forming at least one fastening region on the first component, wherein the fastening region is moulded with a surface structure of grooves;
- and
- connecting the first and second components to one another by ultrasonic welding at the fastening region, wherein the grooves each have a triangular-shaped cross-section and each terminate at a groove apex, wherein a space between the apexes of adjacent grooves is between 0.1 mm and 2 mm, and wherein the grooves are arranged as elongated, parallel rows and are depressed into the fastening region.
A method for producing a connection between a vehicle bumper and a sensor holder, comprising:
- forming at least one fastening region on the vehicle bumper comprised of a plurality of grooves each having a triangular-shaped cross-section and each terminating at a groove apex, and wherein the grooves are arranged as elongated, parallel rows and are depressed in the fastening region surface;
- wherein a space between the groove apex of adjacent grooves of the fastening region of the vehicle bumper is approximately 0.7 mm;
- forming at least one fastening region on the sensor holder comprised of a plurality of grooves each having a triangular-shaped cross-section and each terminating at a groove apex, and wherein the grooves are arranged as elongated, parallel rows and are depressed in the fastening region surface;
- wherein a space between the groove apex of adjacent grooves of the fastening region of the sensor holder is approximately 0.7 mm;
- and
- connecting the vehicle bumper and the sensor holder to one another by ultrasonic welding in the fastening regions of the vehicle bumper and sensor holder.
