PURPOSE: To produce the subject molding having a specific thickness and electri cal resistance and useful as a casing for electromagnetic shielding materials and various electronic and electrical apparatuses by compounding a thermo plastic resin with carbon fibers. CONSTITUTION: This molding is obtained by compounding a thermoplastic resin with carbon fibers having 2-20mm length, using the resultant pellets compounded so as to provide 20-60wt.% fiber content and injection molding the pellets into a metallic mold having a cavity in a desired shape while melting and kneading the pellets with an injection molding machine having a compression ratio within the range of 1.2-1.9. The resultant molding is provided with a platy part having 0.5-2.0mm thickness and <=2Ω/cm electrical resistance. |
