Method for producing a moulded plastic product

Abstract

There is disclosed a method for producing a molded plastic product having an outer skin and in inner core. The method is particularly suitable for making structural products such as panels or the like from recycled plastic material. The method comprises the steps of: providing a mold having a mold cavity; forming an outer skin from a first plastic material on at least two opposed surfaces inside the mold cavity; forming an inner core from a second plastic material inside the mold cavity; and at least partially curing the plastic materials to form a molding inside the mold cavity via the application of heat. The method is characterised by the subsequent steps of (optionally pre-cooling the molding and then) simultaneously cooling the molding and compressing the molding so as to reduce its size in at least one dimension to a desired dimension of the finished product.
