INDUCTIVE WELDING ASSEMBLY & METHOD USING CONDUCTIVE HEAT TRANSFER STRIP
An induction welding assembly and inductive welding method is disclosed. A tooling block includes a workpiece zone, a conductive heat generation and transfer member, and a heat shield, with the conductive heat generation and transfer member being disposed between the workpiece zone and the heat shield. A first workpiece and a second workpiece may be disposed within the workpiece zone such that the first workpiece is disposed between the conductive heat generation and transfer member and the second workpiece. The heat shield, conductive heat generation and transfer member, first workpiece, and second workpiece may be pressed together. An induction coil may be positioned in spaced relation to the heat shield and may be operated to heat the conductive heat generation and transfer member. Heat is conductively transferred by the conductive heat transfer member to the first workpiece to weld the first workpiece and the second workpiece together.
TUBE HEATER AND SEALER AND METHOD FOR SEALING THERMOPLASTIC TUBES AND PIPES
An apparatus and method of closing a wide variety of thermoplastic tubes, in particular with Shore hardnesses of around 50 (A) to above 100 (A), where the tubes having inside diameters of 1.6 mm to 35 mm and/or wall thicknesses of 0.8 to 4.8 mm. The method involves use of a tube heater having at least one heating element. The heating element has at least four heatable regions which are movable with respect to one another. The tube heater is configured to enclose, in the applied state, at least 75% of the circumference of the tube while bearing against the latter over its circumference at at least four points which are spaced apart from one another. One of the key advantages is that, prior to compression, the tube can already have been heated at a plurality of points on the tube.
METHOD AND DEVICE FOR ELECTROMAGNETIC SPOT WELDING OF MOULDED PARTS
A device for electromagnetic spot welding of moulded parts includes a pressurizing body, and first displacing means for moving a pressurizing body against the moulded parts or vice versa to join contact surfaces of the moulded parts to be fused by welding under pressure. The pressurizing body includes an inductor that generates an electromagnetic field in at least the contact surfaces of the moulded parts. A shielding is provided in the pressurizing body around at least a part of the inductor to protect against overheating. A heat sink is provided in the pressurizing body in between the inductor and the pressurizing surface in direct contact with the inductor and the pressurizing surface. The inductor includes cooling means configured for cooling the inductor, the shielding and the heat sink. A method for electromagnetic welding of moulded parts using the device.
Treatment device and treatment method
A technique for stable, high-speed treatment of reinforcement fiber. In a state where a unidirectional fiber bundle is held between a supporting surface of a support and a pressing surface of a resonator ultrasonically vibrating in a pressing direction perpendicular to the supporting surface, a pressed part of the unidirectional fiber bundle pressed by the pressing surface is moved in a longitudinal direction of the unidirectional fiber bundle. By doing so, the unidirectional fiber bundle can be stably treated at high speed when the unidirectional fiber bundle is opened or impregnated with a resin.
SEALING DEVICE AND METHOD FOR SEALING A LID MATERIAL TO SEALING AREAS OF A BLISTER WEB OR OF A BLISTER CAP
A sealing device for sealing a lid material to sealing areas of a blister web comprises a first, heated sealing tool and a second sealing tool arranged opposite each other and movable relative to each other. A first intermediate element of elastic material is attached to the first sealing tool on a side facing the second sealing tool, and a second intermediate element of thermally-insulating material is attached to the second sealing tool on a side facing the first sealing tool. The first and second sealing tools are movable relative to each other between an opened position and a closed position, in which at least sections of the first intermediate element and of the second intermediate element exert pressure on each other. In the closed sealing position, the first intermediate element rests on the lid material and the second intermediate element rests on lands of the blister web.
