Molding system

Abstract

A molding system and method are provided together with articles produced thereby wherein rapidly setting molding material is introduced into a mold and made to conform to the walls of the mold cavity by movement of the mold prior to the setting of the molding material. Precise automatic control is effected, not only of one or more resinous molding materials but also of catalyst's employed to rapidly set the molding material and also of a plurality of power operated devices which serve to move the mold about a plurality of axes. Automatic control is also effected of power operated means for varying the operation of one or more mixing chambers, valves and the like in a preprogrammed molding cycle. In a particular form, feedback control is employed to assure the predetermined operation of the motors and power operated devices controlling the complete molding operation. Of the structures produced by means of the system defining the invention, composite articles such as plastic pallets and other devices containing similar plastic core portions are provided.
