PRODUCT AND DESIGN

allows for interchangeability between molds of the same size.
The specific design idea is as follows:
(1) Firstly, based on the actual external dimensions of
the auxiliary mold, the shape and size of the electromagnetic
heating shield are carefully designed to ensure that the heating
coil can evenly surround the mold sleeve, thereby achieving a
uniform and efficient heating effect.
(2) Secondly, securely install the designed electromagnetic
heating coil inside the shield. The key to this step is to ensure a
fixed distance between the heating coil and the mold sleeve to
achieve uniform heating. At the same time, it is also necessary
to carefully inspect the wiring and insulation condition of the
