PURPOSE: To enable production of composite material by forming each of a forming die, injection sleeve, piston and storing vessel with ceramic material and connecting a mixing furnace supplying molten alloy metal containing mixture with the storing vessel.

CONSTITUTION: Body parts 101, 201 in both male and female dies a1, a2 are formed with heat resistant metal and ceramic-made inserting cores 102, 202 are set in insert core setting parts 2, 3 in inner part thereof. Further, the injection sleeve B and the piston C are formed both with the ceramic material. The storing vessel D, which the temp. is held with a heating wire 11, and the covering material 13 are arranged to the sleeve B and connected with the ceramic-made mixing furnace E through a molten metal supplying pipe 14. By this method, the molten alloy metal containing mixture 1 of powdery or fibrous carbide, nitride, etc., can be injected into the forming die while holding the fixed temp. Therefore, the composite material containing the mixture 1 can be produced.
