A method and a system including a welding device, an inspection device having an inspection head having two sensors, a controller, and a memory for assessing a butt weld of plastic pipes or fittings in a welding device.

A plastic product having magnetic properties and a method for making the same is provided. The method comprises creating a mixture of a nylon and a metal, melting the mixture to create a melted mixture of the metal suspended in the nylon, injecting the melted mixture into a mold to harden the melted mixture and shape the melted mixture into the product's shape, applying an electrical current to the mold while the mixture is in a viscous state to align the poles of the metal suspended in the nylon in the mixture in a single direction before the mixture has hardened, and applying a magnetic field to the hardened mixture to provide the product with magnetic properties.

A stabilizer manufacturing apparatus for manufacturing a stabilizer to which rubber bushes are heat-bonded is provided with a curing furnace in which high-frequency induction heating is performed, a conveyor for conveying the stabilizer in a conveying direction through the curing furnace, the rubber bushes being pressure-bonded to bonding locations on the stabilizer on which an adhesive layer is formed, power supply devices for supplying power to coils used in the high-frequency induction heating, and coils for generating a magnetic field in portions to be heated of the stabilizer near the bonding locations and for heating the portions to be heated; the coils being separated by a predetermined distance from the portions to be heated of a predetermined number of stabilizers conveyed in the conveying direction.

The present invention relates to a motor vehicle luminous device including at least one first portion that is transparent to at least one laser beam, the portion having at least one first polymer material, and at least one second portion that absorbs the laser beam and is transparent to at least some of the visible spectrum, including at least one second polymer material, the second portion being laser welded to the first portion.

An electric heating device includes a control portion adapted to control electric energy supplied to a heater, based on a before-heating temperature, which is a temperature of at least one of an object, the heater and a heat dissipation portion before the heater generates heat, the control portion is adapted to calculate the temperature of the object, based on the before-heating temperature and the electric energy supplied to the heater.

An apparatus and method for joining pipes includes a plate for melting mating surfaces of the pipes to be joined. Additionally, the apparatus utilizes a vacuum in order to push the first and second pipes together in lieu of hand or mechanical pressure which may be inconsistent. Additionally, the vacuum allows the pipes to be joined to settle on each other in order to create a pressure about a periphery of the end of the pipe being joined to the other pipe. The consistent pressure creates a very strong joint between the first and second pipes.

A polar functional group is added onto a surface of a metallic member. A resin member contains an adhesive functional group. The adhesive functional group and the polar functional group attract each other. A method for joining the metallic member and the resin member to each other includes: heating a junction between the metallic member and the resin member while pressing the metallic member and the resin member against each other with a first load; maintaining temperature of the junction higher than melting temperature of a resin that structures the resin member while pressing the metallic member and the resin member with each other with a second load smaller than the first load; and cooling the junction to temperature lower than the melting temperature while pressing the metallic member and the resin member against each other with a third load larger than the second load.

The present invention concerns an apparatus for ultrasonic welding of at least two material webs comprising a processing sonotrode which can be excited with an ultrasonic vibration, a processing counterpart tool and a material web guide which is so designed that the material web can be passed through between the processing sonotrode and the processing counterpart tool, in which there is provided a device for heating at least one material web prior to the welding operation. To provide an ultrasonic welding apparatus which avoids the stated disadvantages and which nonetheless provides a high processing speed it is proposed according to the invention that the device for preheating at least one material web has a preheating sonotrode which can be excited with an ultrasonic vibration.

Provided are circuit board excellent in interlayer adhesion and solder heat resistance, and production method thereof. The circuit board is produced by a method including: preparing a plurality of at least one kind of thermoplastic liquid crystal polymer (TLCP) films, forming a conductor layer on one side or both sides of a film in at least one of the films to obtain a unit circuit board, laminating the films containing the unit circuit board to obtain a stacked material, conducting thermo-compression-bonding of the stacked material under pressurization to a first temperature giving an interlayer adhesion to integrate the stacked material, carrying out structure-controlling thermal treatment by heating the integrated stacked material at a second temperature which is lower than the first temperature and is lower than a melting point of a TLCP having a lowest melting point out of the plurality of TLCP films.

A device comprising at least one pressure generation unit and a heating unit, the heating unit comprising a two-sided inductor and being configured to generate a uniform alternating magnetic field in an assembly comprising two parts made of composite materials comprising carbon fibers embedded in a resin and a field absorber. The field absorber is configured to absorb the magnetic field and comprising a ferromagnetic material. The field absorber is arranged at the contact walls of the two parts, so as to heat them to at least a transformation temperature of the resin.
