Abstract

PURPOSE:To obtain powder molding material which enables to mold the fine molded product having dimensional accuracy of micron order, by composing it of thermosetting resin compound of which the particle size is unified to a specific particle diameter. CONSTITUTION:An aimed molding material is obtained by pulverizing the resin compound wherein thermosetting resin of phenolic resin, epoxy resin, diallylphthalate resin etc. is added and mixed with incorporating material of curing agent, curing accelerator, stabilizer, coloring matter etc. by a pulverizer such as a bal mill, a hammer mill, an atomizer etc., further classifying it by an electric sieve etc., making its particle diameter below 1mm. and unifying its particle size. Also, powder inorganic filler of silica powder etc. of which the particle diameter is below 1mm. or glass fiber etc. may be further incorporated to said resin compound if necessary.
