Abstract: The invention is a method for manufacturing a cuvette for analyzing liquid, the method comprising applying welding for securing together cuvette parts. During the method, the following steps are carried out: fitting together an upper cuvette part (10) comprising a transparent upper window portion (11) and a lower cuvette part comprising a transparent lower window portion, thereby forming an analyzing space between the upper window portion (11) and the lower window portion, wherein in the fitted-together position, the upper cuvette part (10) and the lower cuvette part contact each other along at least one peripheral, closed weld path, followed by welding together the upper cuvette part (10) and the lower cuvette part along a weld path in a leakproof manner.

Abstract: An ultrasonic welding method for joining a first thermoplastic part and a second thermoplastic part without causing visible read-through on an exposed surface of the second part. The method includes arranging the first part on an inner surface of the second part. The inner surface is opposite the exposed surface. The first part has an interface portion contacting the inner surface. The method includes causing a horn of an ultrasonic welding stack to be pressed against the first part by applying ultrasonic energy oscillating at a frequency in a range of 45-70 kHz through the horn, to thereby join the first part and the second part together. The horn has at least one protruding distal portion configured to penetrate through the first part as the ultrasonic energy is imparted through the horn. The distal portion has a length longer than a thickness of the first part. A collapse distance of a weld formed at the interface portion is less than the thickness of the first part, to avoid read-through effects on the exposed surface of the second part.

Abstract: The method of bonding a first object (1) to a second object (2) uses a connector, the connector having a first sheet portion and a second sheet portion (32). The first sheet portion has at least one outwardly protruding first attachment portion (33), and the second sheet portion has at least one outwardly protruding second attachment portion (34). The connector (3) further has a spacer between the first and second sheet portions. For bonding, the first and second objects (1, 2) and the connector (3) are positioned relative to each other so that the connector is placed between the first and second objects. Then the first and second objects (1, 2) are pressed against each other while mechanical vibration energy impinges on the first and/or second object until a first flow portion of thermoplastic material of the first object in contact with the first attachment portion(s) and a second flow portion of thermoplastic material in contact with the second attachment portion(s) become flowable allowing the respective attachment portions (33, 34) to be pressed into material of the first and second object, respectively. After re-solidification of the flow portions, a positive-fit connection between the first and second objects via the connector results. The spacer defines a width (w) of a gap between the first and second objects (1, 2) after bonding.
