Method and device for preheating a mold for injection molding
A method and device for pre-heating a first molding surface of a mold with an open position and a closed position defining a closed cavity between the first pre-heated molding surface and a second molding surface. A core is inductively heated outside the mold by placing the core inside a coil having an AC current passing there through. The core is inserted between the molding surfaces of the mold in the open position. The first molding surface is preheated by transferring the heat between the core and the first molding surface. The core is then removed and the mold is closed.

SEGMENTED TOOLS HAVING THERMAL EXPANSION ABATEMENT
Systems and methods for manufacturing composite parts may include preheating a tool having a base made of a first material having a first coefficient of thermal expansion and a tooling surface made of a second material having a second coefficient of thermal expansion. Preheating includes heating the tooling surface at a first rate using a first heating system and heating the base at a second rate using a second heating system. Differences in dimensional growth due to thermal expansion of the base and the tooling surface are compensated by spaced-apart box structures coupling the tooling surface to the base, each of the box structures being made of the second material and having a first end fastened to the base and a second end fastened to a back side of the tooling surface.
