A method for manufacturing a three-dimensional structure including: preparing a first structure including a fixing face; fixing a plastic layer to the fixing face of the first structure; preparing a conductive wire; and operating an ultrasonic head to apply ultrasonic waves to the conductive wire and to press the conductive wire against the plastic layer, and thereby partly embedding the conductive wire into the plastic layer.

A method of bonding a first object to a second object, including the steps of: providing a profile body having a first profile body portion; providing the first object, wherein the first object has thermoplastic material; providing the second object, wherein the profile body is separate from and attachable to the second object or wherein the second object includes the profile body; embedding the profile body in the first object such that the first profile body portion is within the thermoplastic material of the first object. Embedding the profile body in the first object is caused by mechanical energy impinging on the first object and/or on the second object while the first object and the second object are pressed against each other.

A method of anchoring a connector in a heterogeneous first object that includes a first building layer and, distally of the first building layer, an interlining layer. The method includes providing the first object and the connector, which includes thermoplastic material in a solid state; contacting the connector with the first building layer; applying a first mechanical pressing force to the connector until the first building layer is pierced by the connector and a distal portion of the connector reaches into the interlining layer; applying a second mechanical pressing force and mechanical vibration to the connector until a flow portion of the thermoplastic material is flowable and penetrates structures of the first object, and a distally facing abutment face of the head portion abuts against the metal profile in a region next to the opening; and letting the thermoplastic material resolidify to yield a positive-fit connection.

A method of mechanically securing a first object including a thermoplastic material in a solid state to a second object with a generally flat sheet portion, with a perforation of the sheet portion, and with the sheet portion having an edge along the perforation is provided, wherein the first object is positioned relative to the second object so that the edge is in contact with the thermoplastic material and wherein mechanical vibration energy is coupled into the assembly including the first and second objects until a flow portion of the thermoplastic material due to friction heat generated between the edge and the thermoplastic material becomes flowable and flows around the edge to at least partially embed the edge in the thermoplastic material. After the mechanical vibration stops, the thermoplastic material is caused to re-solidify, whereby the re-solidified thermoplastic material at least partially embedding the edge anchors the first object in the second object.

The relates to a method of mechanically securing a first object to a second object and includes the steps of: providing the first object including thermoplastic material in a solid state, providing the second object with a generally flat sheet portion having an edge, positioning the first object relative to the second object and bringing the first object and the second object to a relative movement to each other. The relative movement includes a rotational movement, such that a melting zone including flowable thermoplastic material is formed and such that thermoplastic material of the melting zone flows around the edge to at least partially embed the edge in the thermoplastic material. The invention further concerns a connector that is suitable for being used in a method according to the invention.

A tool presses a joining element against a first object into a first opening of the first object while mechanical vibration energy is coupled into the first object and the joining element. Vibration energy and pressing force make the thermoplastic material of the distal portion of the joining element flowable and interpenetrates structures of the first object to yield, after re-solidification, an anchoring of the distal portion of the joining element in the first object. The second object is placed so that a proximal portion of the joining element is inserted into a second opening, and the first and second objects are pressed against each other while mechanical vibration energy is coupled into one of the first and second objects, until thermoplastic material of the joining element proximal portion is made flowable and interpenetrates structures of the second object to yield, after re-solidification, an anchoring in the second object.

There is provided a method for producing a metal-resin composite including a metal member and a resin member which are joined together, the resin member containing at least a thermoplastic resin. The method includes a step of joining together the resin member and the metal member by melting the resin member with the frictional heat generated in the surface of the metal member on its side opposite to the resin member in a state where the metal member and the resin member are superposed. The melting point of the thermoplastic resin is 260° C. or more.
