Abstract
(EN)
The present disclosure relates to a tool such as an injection moulding tool or an embossing tool. A heating device including a stack of layers is provided for heating a tool surface. The stack may include a coil carrier layer with a number of wound coils for generating a magnetic field, and a conductive top layer, being adjacent to the tool surface currents are induced in the top layer to heat the surface. Efficient heating may be provided by solutions involving low resistivity layers that lead currents to the top layer without themselves developing heat to any greater extent. A conduction frame device can be provided beneath the top layer and around the perimeter thereof to provide reliable contact with a backing layer.

La presente descripción se refiere a una herramienta tal como una herramienta de moldeo por inyección o una herramienta de estampado. Se proporciona un dispositivo de calentamiento que incluye una pila de capas para el calentamiento de la superficie de la herramienta. La pila puede incluir una capa portadora de la bobina con un número de bobinas devanadas para la generación de un campo magnético y, en una capa superior conductora, que es adyacente a la superficie, de la herramienta, se inducen corrientes en la capa superior para calentar la superficie. Se puede proporcionar un calentamiento eficiente mediante soluciones que implican capas de baja resistividad que dirigen las corrientes a la capa superior sin que desarrollen en sí mismas calor en cualquier grado mayor. Se puede proporcionar un dispositivo de bastidor de conducción por debajo de la capa superior y alrededor del perímetro de la misma para proporcionar un contacto fiable con una capa de soporte.
