As described on pages 95 to 99 of the November issue, 1. Molten resin that does not contain a blowing agent is injected into the mold space from one or more nozzles, and then forced pressure such as nitrogen or air is applied. Gaske Injecting into the resin & C process is this progress because the gas invades the resin in a branched manner? (referred to as viscous finger IJing)
, a large number of ribs are formed in the resin. This molding method can save 2 raw materials, and
It has the advantage of being lightweight, and the present invention takes full advantage of this. 2 is a first resin material molded by the above-described process, and 3 is a second resin material injected into the hollow part of the resin material 2, in which a viscoelastic material having vibration-proofing properties is used. ing.
