Device for Producing a Metal-Plastic Connection by Means of Clinching and a Produced Component

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

This patent describes a device for creating a secure connection between a metal and a plastic component using a process called clinching. The device features a die with a negative mold of the component and a punch that moves into the die. Uniquely, the die includes a ring groove with a diameter larger than that of the negative mold, which aids in the joining process.

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

• Automotive industry for assembling metal-plastic hybrid parts like car body panels or brackets
• Electronics manufacturing for securing metal heat sinks to plastic housings
• Home appliances for joining metal structural pieces to plastic panels
• Aerospace for lightweight, strong assemblies combining metal and plastic
• Consumer products industry for making durable, composite casings or enclosures

BenefitsContent extracted from patent full text and abstract with AI.

• Allows secure bonding of dissimilar materials (metal and plastic) without adhesives or fasteners
• Enables lightweight, hybrid structures that combine strength and flexibility
• Automated and repeatable process suitable for mass production
• Reduces assembly time and costs compared to traditional joining methods
• Minimizes thermal or chemical stress to parts since it avoids high heat or aggressive chemicals
