The machine that inserts the metal part into the plastic part called a high-frequency inducer?

The working principle of the high frequency induction welding machine: the metal material is embedded in the plastic product, under the action of the high frequency magnetic field. The molecules are polarized and arranged according to the direction of the electric field. Due to the high-frequency electric field, the direction changes at an extremely fast speed, and the metal material heats up due to dielectric loss. Melt plastic parts. Under certain pressure, metal can be implanted into plastic parts, or two plastic parts can be welded together. Under certain pressure, they can be firmly bonded together after cooling.
