A Method of Manufacturing Plastic Articles
Abstract
A commonly known method of manufacturing plastic articles, for example dies made of composites based on epoxy resins with a metallic filler and hardener is to mold the composite by casting in a mold subsequently hardening the obtained casting, and extracting from the mold. Frequently used as a filler is iron powder or other powders of ferromagnetic substances. However, the density and wear resistance of the working surfaces of castings completely depend on the quantity of metallic filler introduced into the composite. The purpose of the Russian invention is to obtain castings with predetermined density and wear resistance of the working surface by introducing in the composite a much smaller quantity of metallic filler through controlled distribution of filler in the volume of the article.
