1. Material selection: Generally, imported acrylic materials with a thickness of about 2mm, good light transmittance, flatness and hardness are used to ensure the fineness of the finished product and the crystal texture of the finished product (market price: 1.2X2.4 meters, 130 (about 100 yuan).

2. Material processing (base color): Use self-spray paint or air pump spray paint on the reverse side of the acrylic material as the base color of the badge (spray the color of the design). In order to apply the color evenly, spray 2-3 times, each layer should not be too thick, and there should be a time interval between layers.

3. Engraving: Load the processed materials into the engraving machine, input the designed processing path file and then carry out plane and curved surface engraving (for badge processing, use JDSign engraving machine, processing time is 4 minutes and 30 seconds).

4. Dust removal: After the engraving is completed and the material is removed, use a slightly harder brush (such as a toothbrush) with an air pump to clean up the remaining material debris. It is best to rinse it with cold water and let it dry naturally to eliminate static electricity.

5. Surface pretreatment: Spray a layer of car varnish on the engraving surface after dust removal and drying, and dry it in the oven (the oven temperature is kept at about 60 degrees).
