Method and device for joining moulded parts by electromagnetic welding

A method for joining moulded parts by electromagnetic welding. A joining inductor is moved along contact surfaces of the moulded parts, generating an electromagnetic field in an induction-sensitive component of the moulded part(s) to heat a thermally activated coupling means of the moulded part(s) to above a melting temperature of the coupling means. The strength of the electromagnetic field suitable for joining is determined by previously moving a sensing inductor along the contact plane, generating a relatively weak electromagnetic field to slightly heat the thermally activated coupling means to a sensing temperature, measuring the field strength generated by the sensing inductor in the moulded part(s), determining a discrepancy between the measured field strength of the sensing inductor and the field strength suitable for joining, and adjusting the field strength suitable for joining to close the discrepancy. A device for carrying out the method.

Glass/resin composite structure and method for manufacturing same

A composite structure with high pressure resistance that is suitable for a flow channel is produced by reducing the number of components while maintaining the excellent chemical resistance and high stress tolerance inherent to a glass substrate and a resin substrate. A glass substrate surface is modified with a hydrolyzable silicon compound, and the glass substrate is brought into contact with the resin substrate. Subsequently, the contact surface between the glass substrate and the resin substrate is heated to a temperature from the glass transition temperature to the pyrolysis temperature of the resin substrate, eliminating gaps between the glass substrate and the resin substrate to bring them into close contact with each other, and causing chemical binding or anchor effects between the glass substrate and the resin substrate via the hydrolyzable silicon compound. Thus, the glass substrate and the resin substrate are firmly fixed to each other.
