A METHOD OF PRODUCING A POLYMER BODY BY COALESCENCE AND THE POLYMER BODY PRODUCED

WIPO Patent Application WO2002007910

A9

A method of producing a polymer body by coalescence, wherein the method comprises the steps of a) filling a pre-compacting mould with polymer material in the form of powder, pellets, grains and the like, b) pre-compacting the material at least once and c) compressing the material in a compression mould by at least one stroke, where a striking unit emits enough kinetic energy to form the body when striking the material inserted in the compression mould, causing coalescence of the material. A method of producing a polymer body by coalescence, wherein the method comprises compressing material in the form of a solid polymer body in a compression mould by at least one stroke, where a striking unit emits enough energy to cause coalescence of the material in the body. Products obtained by the inventive methods.
