A heat sink for use in induction welding includes a number of tiles, wherein the tiles are electrically non-conductive and have a thermal diffusivity of greater than about 25 mm2/sec. A joint flexibly joins the tiles together.

A method of induction welding a first thermoplastic composite (TPC) to a second thermoplastic composite (TPC) using an induction coil includes forming a weld interface area between the first TPC and the second TPC, cooling the first TPC with a cooling apparatus before heating by the induction coil, and inductively heating the weld interface area with the induction coil after cooling the first TPC.

A heat sink for use in induction welding includes a flexible backing and a number of tiles disposed on the flexible backing in a single layer, wherein the tiles are electrically non-conductive and thermally conductive.

A heat sink for use in induction welding includes a number of tiles, where the tiles are electrically non-conductive and thermally conductive, a joint flexibly joining the tiles together, and a fluid path formed through the heat sink for communicating a coolant therethrough.

A method of dissipating heat from a surface of a first thermoplastic composite (TPC) being inductively welded with a second thermoplastic composite (TPC) includes flexing a heat sink during placement to conform to the surface of the first TPC, cooling the heat sink, applying inductive heat to a weld interface area between the first TPC and the second TPC, and drawing off heat via the heat sink from the surface of the first TPC.

A method of induction welding a first carbon fiber thermoplastic composite (TPC) to a second carbon fiber thermoplastic composite (TPC) using an induction coil includes aligning the first TPC with the second TPC to form a weld interface area, flexing a heat sink onto a surface of the first TPC between the weld interface area and the induction coil, and inductively heating the weld interface area with the induction coil.

The welding chip heats and melts the first welded part and the second welded part, and includes a projected part, a first extension part, and a second extension part. The projected part has a tubular shape with a bottom. One end of the tubular shape extending in a predetermined direction opens and the other end of the tubular shape is closed. The projected part is pushed into the first welded part and the second welded part in the predetermined direction from the opening one end of the tubular shape. The first extension part has a shape extending from a tube outer surface of the projected part and extending annularly around the predetermined direction. The second extension part has a shape extending from the first extension part to the opening one end of the projected part in the predetermined direction and extending annularly around the predetermined direction.

A method for manufacturing a thermoplastic composite product includes: providing a first and second thermoplastic composite component made from a consolidated stack of thermoplastic composite plies, said first and second component having a first and second ply drop off, respectively. The first and second components are positioned such that the first ply drop off and the second ply drop off are aligned, and the first and second components are fixedly connected by means of heating. The stacks of plies for the first and second components are constructed by stacking the plies in a stacking direction wherein the plies are arranged such that plies at a different position along the stacking direction are laterally offset relative to each other for the purpose of forming the first ply drop off and the second ply drop off, respectively, before consolidating.

A sealing system for heat sealing superimposed walls of heat-sealable film material, e.g. in the production of pouches. The sealing section comprises two or more sealing stations arranged in series along a linear path for the superimposed walls dispensed from an infeed section. Each sealing station comprises a sealing device with first and second jaws and an actuator device to move the jaws between an opened position and a clamped position. Each sealing device comprises a motion device that is configured to move the first and second jaws in synchronicity with the superimposed walls when clamped between the first and second jaws. Each sealing station has a cooling device that is configured to continuously cool at least one of the jaws. At least each first jaw comprises at the respective front surface thereof at least one impulse heatable member embodied as a susceptor element that extends along the respective front surface. Each sealing station is configured to perform an integrated impulse sealing and cooling cycle.

An automatic control unit for field vulcanizing press is provided. The control unit helps to monitor and control all three essential vulcanizing parameters viz. temperature, pressure and time, either locally or through remote access. Data logging, local monitoring & control of vulcanizing parameters or remote monitoring and control of vulcanizing parameters using a smart device are the major features of this control unit in which remote monitoring and control of vulcanizing parameters is the unique feature of this control unit. A video recording unit is also provided to record entire splicing operation and also there is option for online video streaming facility and it will help to monitor the entire splicing operation from a remote-control station.
