Described is an instrumented heat sink for use in electromagnetic welding of molded parts. The heat sink includes a material having a thermal conductivity according to ASTM C1113 at a temperature of 25° C. of greater than 25 W/m-K, and further includes a machined cavity and, accommodated therein, a sensing device for measuring the temperature at a location within the cavity, wherein further a dimensional gap exists between the sensing device and a wall of the cavity. The heat sink is advantageously used in a method and apparatus of connecting molded parts by electromagnetic welding. Cooling of the outer surface of a molded part is provided by the instrumented heat sink in direct contact with the outer surface and provides improved control over weld temperatures during welding.
An instrumented heat sink for use in electromagnetic welding of molded parts, the heat sink comprising a material having a thermal conductivity according to ASTM C1113 at a temperature of 25° C. of greater than 0.1 W/m-K, wherein the heat sink comprises a machined cavity and, accommodated therein, a sensing device for measuring the temperature at a location within the cavity, wherein further a dimensional gap exists between the sensing device and a wall of the cavity such that deformations of the sensing device and of the heat sink are substantially uncoupled.
