Abstract: The present invention of a device for instantly pre-heating dies comprises an inductive heating coil disposed between a first die and a second die. The inductive heating coil is a coil body in spiral shape having characteristics of conducting high cycle wave induction heat energy. When the first and the second dies are separated by a mechanical arm, the inductive heating coil is disposed between die surfaces of the first and the second dies, so that high cycle wave induction heat can take effect on a die contact part. Thus the die contact part can be pre-heated instantly.

Abstract: The present invention of a device for advancing even distribution of high cycle wave magnetism uses a coil body having characteristics of conducting high cycle wave magnetism energy. The coil body is coiled in such a way that appears to have undulating distributed layers structure. A plurality of neighboring coil parts is annularly formed to become the coil body. Magnetism goes through any two neighboring coil parts will not repel or counteract each other because the neighboring coil parts are not on the same plane. Thus the present invention can advance high cycle wave magnetic field distributed more evenly.
