Manufacturing technology of nacre workpiece

摘要

Manufacturing technology of nacre workpieceThe manufacturing process includes the following steps:-A die (10) is provided with an indentation (14) corresponding to a part (12) to be manufactured,-A first transparent material (18) with a first optical refractive index is injected into the fingerprint for the first time,-The first injection is stopped before the first transparent material (18) completely fills the fingerprint (14),-The second transparent material (20) is injected into the fingerprint for the second time, and the second optical refractive index is greater than the first optical refractive index,-Cooling the part (12) formed in the indentation (14), and-The workpiece (12) thus formed is demoulded.Abstract figure: Figure 3
