PLASTIC INJECTION MOLDED PRODUCT SHOWING FEEL OF METAL MATERIAL

摘要

Provided is an injection molded plastic product, which causes no drop in reflection ratio of polyhedral metal particles even at crossing points of flow of plastic materials, and thus shows a uniform metal-like texture over the whole surface thereof. The injection molded plastic product is obtained by mixing a molten plastic resin solution with polyhedral metal particles(198) formed by crushing aluminum/magnesium alloy, and solidifying the resultant mixture. The aluminum/magnesium alloy comprises aluminum and magnesium in a ratio of 3:7 to 7:3. The polyhedral metal particles have an average diameter of 5-120 micrometers. A surface of the polyhedral metal particles is coated with a metal-like material or colored with a desired pigment.
