Utilization method of mixed material for laser direct structuring

The invention discloses a utilization method of a mixed material for laser direct structuring. The method comprises the following steps: 1, putting a secondary material of the mixed material for laser direct structuring in a crusher, and crushing to form fine particles; 2, adding the crushed secondary material to a raw material according to a proportion of 30% or less; 3, putting the material containing 30% or less of the secondary material in an injection machine, and injecting to form a finished plastic product; and 4, making antennas on the finished plastic product through the laser direct structuring technology. The mechanical data of the finished plastic product injected by using the raw material containing 30% or less the secondary material has good stability, a difference between the plating starting time of the chemical plating of the antennas made of the material used in the invention and the plating starting time of the chemical plating of antennas made by adopting a finished plastic product injected by completely using the raw material is small, the quality of the antennas is same to the quality of the antennas formed through chemical plating on the plastic product injected by completely using the raw material, so the secondary material is reused to reduce the production cost and the management cost.
