[0047] (1) Preparation of the positive mold: use computer-aided design (CAD) to design the positive mold, convert the design drawings into digital information of digital machine tools through digital-to-analog conversion, and select brass as the processing material to process and shape according to the design size.
[0048] (2) Preparation of female mold: Take polydimethylsiloxane and monomer curing agent at a ratio of 11:1 (w / w), mix them with a vortex mixer, and place them in a vacuum box for vacuum degassing for 15 minutes. After the air bubbles are exhausted, pour the liquid into the prepared brass male mold slowly, avoid the generation of air bubbles during the pouring process, place it in the oven, set the oven temperature to 100°C, keep it warm for 1.5 hours, take it out, and demould , that is, the negative mold of PMDS is obtained.
