Bi-color extruded product and method of production

Embodiments of the present disclosure disclose bi-color extruded products and methods of production. A specific implementation mode of the production method comprises the steps that gas is conveyed into a gas channel through a gas inlet hole of a mold; controlling a first extrusion head to extrude an insulating material into a first cavity channel of the mold so as to form an insulating layer of the double-color extrusion product; controlling a second extrusion head to extrude a conductive material into a second cavity channel of the mold so as to wrap the insulating layer and form a first conductive layer of the double-color extrusion product; the transmission mechanism is controlled to convey the conductive metal sheet so as to cover the local surface of the first conductive layer, and a second conductive layer of the double-color extrusion product is formed; the first cavity channel is located between the air channel and the second cavity channel. According to the embodiment, the double-color extrusion pro
