In an example of a method of making a flowcell, an organic solid support including sidewalls and a top is provided. A bottom surface of the organic solid support adjacent to the sidewalls provides a laser bonding foot. In the method, the laser bonding foot is bonded to an inorganic solid support to form a channel having sidewalls and a top defined by the organic solid support.

An apparatus may include a film support roller supporting a film roll and a housing that may include a sealing portion having an aperture sized to receive a top portion of a container. The housing may define a film path leading from the film roll to the sealing portion. A guide support assembly may have a ramp and at least one guide truss positioned along the film path. The ramp and the guide truss may guide the film across the aperture within the sealing portion, covering the aperture. The motor may advance the film along the film path. The heating element may emanate energy. The controller may cause the motor to advance the film onto the ramp and cause the heating element to emanate energy to cause the film to seal the top portion of the container.

An infrared welding system for joining two parts made of thermoplastic material comprises a pair of infrared heaters for heating the two parts while spaced from each other; and energizing the infrared heaters to emit infrared heat and directing the emitted infrared heat onto selected portions of the opposed surfaces of the parts to melt at least portions of the opposed surfaces, while directing an inert gas onto the selected portions to prevent ignition of the melted thermoplastic material. The two parts are clamped together by moving at least one of the parts toward the other part to press the melted surfaces of the parts into contact with each other. The parts are cooled while they remain clamped together to solidify the molten thermoplastic material and thus weld the two parts together.

The invention relates to a process for the production of at least two-layer thermoplastic sheets via thermal welding of at least one thinner thermoplastic sheet with density (D1) and of at least one second thinner thermoplastic sheet with density (D2), where the density (D1) of the first thinner thermoplastic sheet is smaller than the density (D2) of the second thinner thermoplastic sheet. The process introduces at least one first heating element and at least one second heating element along mutually offset planes between the two thinner thermoplastic sheets, where the surfaces of the thinner thermoplastic sheets do not touch the surfaces of the heating elements. The first heating element transfers a quantity of energy (E1) to the surface of the first thinner thermoplastic sheet, and the second heating element transfers a quantity of energy (E2) to the surface of the second thinner thermoplastic sheet, where the quantity of energy (E1) is smaller than the quantity of energy (E2).

The plastic preheating arrangement for a plastic welding device comprises a support, at least one first preheating device and a pivoting arrangement with which the at least one first preheating device can be pivoted relative to a first surface of the support from a starting position into a preheating position. In this manner, an undercut of a first component can be circumnavigated and the first component can be heated by means of the first preheating device.

Disclosed is a heat welding apparatus for combining a plastic fuel tank and plastic parts, and a method of combining the plastic fuel tank and the plastic parts using the apparatus. When a plastic part is heat-welded onto an inner surface of the plastic fuel tank, a melting unit simultaneously heats and melts a welding portion of the inner surface of the plastic fuel tank, to which the plastic part is joined, and a welding surface of the plastic part inside the plastic fuel tank, and then the welding surface of the plastic part is heat-welded to the welding portion of the plastic fuel tank after melting without delay.

A method of making a flowcell includes bonding a first surface of an organic solid support to a surface of a first inorganic solid support via a first bonding layer, wherein the organic solid support includes a plurality of elongated cutouts. The method further includes bonding a surface of a second inorganic solid support to a second surface of the organic solid support via a second bonding layer, so as to form the flowcell. The formed flowcell includes a plurality of channels defined by the surface of the first inorganic solid support, the surface of the second inorganic solid support, and walls of the elongated cutouts.

An exterior body panel assembly having a Class A painted surface, mold-in color or non-Class A surface, and process of infrared welding components of the assembly. Panels of the assembly are placed on a nesting structure and the inside half of the structures are brought together with the other for a fit check. Panels are separated and an infrared heating fixture then heats the various areas to be heated on the panels. The areas on the panels are heated depending on the thicknesses of the parts at each area and surface geometries to be welded. The parts are immediately clamped back together under pressure for joining and cooling of the joined surfaces in the clamped arrangement.
