MOLDING OF PLASTIC

摘要

After applying powder of thermoplastic or themosetting resin on surface of a moulding die by electrostatic plating, material resin is charged to form a prod. with electroconductive film of its surface. The mould is preheated, and the preheating temp. is melting pt. of the powder resin +10 deg.C at least and is at least the softening pt. of the powder resin. The powder resin is mfd. according to wet-type granulating method to granulate mixt of water soluble solvent. The resin is insol. in water and soluble in the solvent. The electroconductive powder is metal powder of dendrite form.
