That looks like a concealed cabinet hinge, also often called a European-style hinge or cup hinge.
These hinges are popular for modern cabinets because they offer several advantages:
* Concealment: The majority of the hinge mechanism is hidden inside the cabinet when the door is closed, providing a clean, seamless look.
* Adjustability: They typically have multiple screws for three-way adjustment (side-to-side, up-and-down, and in-and-out/depth) to perfectly align the cabinet door.
* Built-in Mechanisms: Many, like the one pictured, include features like soft-close or self-closing capabilities, often visible by the cylindrical piston mechanism (though it's hard to tell for sure if yours is soft-close without more context).
The hinge consists of two main parts:
* The Cup (or Hinge Body): This is the larger, main part that is typically mounted into a large 35mm hole (called a bore or cup hole) drilled into the back of the cabinet door.
* The Mounting Plate: This flat piece is screwed to the inside of the cabinet frame or side panel. The hinge body then clips or screws onto this mounting plate.
Based on the way it's designed to bring the door flush against the cabinet opening, this specific type of hinge is likely a:
* Full Overlay Hinge: Used when the cabinet door fully covers the cabinet opening and rests against the cabinet face/frame.
