APPARATUS FOR PRODUCING CAST TYPE POLYAMIDE RESIN MOLDED OBJECT

摘要

PROBLEM TO BE SOLVED: To provide the producing apparatus with which voids in a plate-shaped molded object or the like on the surface thereof are eliminated. SOLUTION: A spacer 5 is interposed between a pair of side panels 4, 4 to from a cavity 7 and a polymerizable lactam soln. is injected into the cavity 7 to be anionically polymerized to produce a plate-shaped product of a cast polyamide resin. In this apparatus, packings 30 preventing the leak of the polymerizable lactam soln. are interposed between the side plates 4 and the spacer 5 and the corner parts 32 of the spacer 5 forming a part of a cavity surface 31 are formed into taper surfaces 34 with respect to side plate surfaces 33.
