Title: Forming method of metallic base composite material
Inventor: MAEDA SHUHEI
IPC: C22B9/22
Filed: 1992-02-07
Abstract: PURPOSE:To reduce the working cost, form a molded product having a complicated shape, enhance the dimensional precision and improve the quality of molded product. CONSTITUTION:The raw material composed of the metallic matrix and the adding material is supplied inside a plunger room 14 in the un-molten state, and the raw material is melted with the induction heating at the neighborhood of a nozzle 20 formed at the top of a cylinder 13. The molten material is pressurized with a plunger 12, and ejected from the nozzle 20. The ejected raw material is filled inside a cavity 28 of a forming die 22. Because the time until being filled becomes short, and the molten state is not continued in the long time, so the metallic matrix and the adding material are not separated due to the difference of specific gravity. Accordingly, the adding material can be uniformly dispersed in the metallic matrix without stirring. And the reaction between the metallic matrix and the adding material can be suppressed to the utmost.
