Pink diamonds have long been regarded as treasures by experts. The natural pink color of the pink diamond is due to the change of the fusion structure between the minerals accumulated in the rough diamond and the surrounding environment, so it is pink. In the past 20 years, pink diamonds have been mined and processed due to the mining of the Argyle mine in Australia, but the number is still limited. The rarity and beauty of pink diamonds make it an important auction at the Christies jewelry auction in the world of jewelry auctions. In 1994, Jiashide auctioned a 19.66-carat pink diamond at the Geneva, Switzerland auction price of $377,483 per carat, for a total value of $7.4 million. In 1995, Sotheby auctioned a 7.37-carat light purple pink diamond that sold for $818,863 per carat and totaled $6 million. For a long time, there have not been enough pink diamonds anywhere in the world to meet the needs of extensive and in-depth research. At present, the Gem Trade Laboratory of the GIA (Gemological Institute of America) has the results of the identification of 1,500 pink diamonds and related data. The characteristics and color grading system of natural pink diamonds have been determined through research.
LSR Injection Mould, is also called Liquid Silicone Rubber Injection Moulding, LSR Injection Mold & LIM, which can produce liquid silicone rubber parts or products by injection molded machines, not by traditional silicone rubber compression machines using traditional production method, but by liquid silicon rubber injection mould production, which is safer, more precise & environmentally friendly & transparent, using less manpower, and having high production efficiency compared with rubber compression mold.
Liquid Silicone Rubber (LSR) has existed since the late 1970s and has become the material of choice for manufacturing rubber parts and products. The distinctive qualities of liquid silicone rubber injection molding make it different from molding conventional high-consistency silicone and other thermoplastic injection molding processes.

Liquid Silicone Rubber injection molding has thousands of applications across a variety of industries, including medical, automotive, infant care, general industrial markets, aerospace, electronics, and many other specialized industries. While liquid silicone rubber injection molding works best for short- and long-run part production, customers can employ the process in the final stages of prototyping. The process is also suitable for the evaluation of different material configurations before green-lighting a project for full production.
