[0027] Below in conjunction with accompanying drawing, the present invention will be further described with specific embodiment, see figure 1 :
[0028] A metal composite panel process, comprising the following steps,
[0029] ① Preparation of plastic core material: inject plastic granule raw material into the extruder for plasticization treatment to obtain plastic hot melt, and extrude plastic hot melt to form plastic core material;
[0030] ②Co-extrusion of plastic core material and metal strip: plastic core material and upper and lower metal strips are co-extruded, and the inner sides of the upper and lower metal strips are covered with film by a compound machine, and the compound machine composites the upper and lower metal strips respectively On both sides of the plastic core material, the plastic film is melted by the waste heat of the plastic core material, and the plastic core material and the upper and lower metal strips are bonded together to obtain a metal composit...
