Method for producing metal-plastic connection between two components, involves carrying out coupling of ultrasonic vibrations in region, which encircles punch from direction of punch or from direction of die

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

This invention describes a method and apparatus for joining metal and plastic components by using ultrasonic vibrations. The process involves applying ultrasonic energy to a specific area around a punch, which partially melts or softens the plastic so it can be joined securely to the metal. The joining (clinching) is achieved using mechanical tools while the materials are held together, resulting in a strong and stable metal-plastic connection.

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

• Production of automotive components that require metal-plastic assemblies (such as dashboards, structural reinforcements, or trim panels)
• Manufacturing of consumer electronics housings where both durability (metal) and light weight (plastic) are needed
• Assembly of appliances with integrated metal and plastic parts (e.g., washing machines, refrigerators)
• Production of medical devices combining plastic flexibility with metal strength
• Fabrication of lightweight but durable parts in the aerospace industry

BenefitsContent extracted from patent full text and abstract with AI.

• Creates a strong bond between dissimilar materials (metal and plastic) using localized ultrasonic energy
• Reduces the need for adhesives, screws, or other mechanical fasteners
• Enables automated, fast, and repeatable production processes
• Allows for lightweight component design by utilizing both metal and plastic advantages
• Potentially reduces production costs by streamlining the assembly process

Patent Abstract

The method involves carrying out the coupling of ultrasonic vibrations in a region, which encircles a punch (5) from the direction of the punch or from the direction of a die (3), where the material of a plastic component (1) is partially plasticized or melted. The clinching of the components is performed when a tool arranged between a blank holder (6) and the die is displaced at simultaneous or at different times. An independent claim is also included for an apparatus for producing a metal-plastic connection between two components.
