Patent ID: 7381358

Claim:
A method for fabricating a product by molding, comprising: melting a resin for molding; and injection-molding said melted resin for molding at a pressure of 10 N/cm 2 to 800 N/cm 2 in a mold cavity in which an electrical or electronic component is set to encapsulate said component, wherein said resin for molding is a saturated polyester resin having a melt viscosity at 200° C. of at least 5 dPa·s and not more than 1000 dPa·s, and a product a×b of at least 500 where a (N/mm 2 ) is a tensile breaking strength and b (%) is a tensile breaking elongation of a film shaped product formed from the resin; and said saturated polyester resin comprises at least 60 mole % of a terephthalic acid or naphthalene dicarboxylic acid in a dicarboxylic acid component of the polyester, and at least 40 mole % of a 1,4-butanediol or ethylene glycol in a diol component of the polyester based on the respective total amounts of the dicarboxylic acid component and the diol component of the polyester.
