PRODUCTION OF FOAMED MOLDED OBJECT

摘要

PROBLEM TO BE SOLVED: To provide a method for stably and simply producing a foamed molded object having dense uniform foam cells at a low cost inclusive of a molded object having a complicated shape. SOLUTION: A foamable thermoplastic resin is extruded in a molten state from a moving die head 20 to be supplied to a mold 30 of an open state to be molded by the mold. Molding can be performed by using a resin of high viscosity and a foamed molded object having dense uniform foam cells can be stably and simply produced in high foaming magnification and a molded object having a complicated shape can be also produced at a low cost.
