Benefits of technology

[0010]This invention relates to molding apparatus and methods for recapturing and reusing heat from a molded product. More specifically, this invention provides apparatus and methods for recapturing heat from a molded product and circulating the heat to raw material, namely resin, to facilitate heating the raw material, to at least warm it prior to molding. Accordingly, this invention provides apparatus and methods for conserving energy in molding processes, making these processes more energy and cost efficient.
[0015]In effect, this invention recovers heat coming from a molded product within the molding press and reuses this heat in an earlier process step. This is advantageous because it provides cost and energy efficiency to the overall molding process.

Problems solved by technology

In the molding press, the water absorbs heat from the molded product and the surrounding part of the molding press, resulting in an increase in the temperature of the water and cooling of the molded product.

Embodiment Construction

[0021]This invention relates to a molding apparatus, especially molding presses, and methods facilitating recapture and reuse of heat produced in the course of molding a product. More specifically, this invention provides apparatus and methods for recapturing heat produced in the course of fabricating a molded product and circulating the recaptured heat to raw material awaiting molding, to heat these materials prior to molding them, thereby reducing the amount of heat required during the actual molding process. Accordingly, this invention provides apparatus and methods for conserving energy in molding processes, thereby making the processes more energy and cost efficient.

[0022]Referring to FIG. 1, a schematic, generic representation of apparatus manifesting aspects of the invention is generally indicated by reference number 1. In this embodiment of the invention, the apparatus includes, at least, a molding apparatus, desirably a molding press, illustrated schematically as 5, a heat ...

Abstract

Apparatus and method for recapturing and reusing heat provided in the course of fabricating a molded product.

Description

FIELD OF THE INVENTION[0001]This invention relates to apparatus and methods for recovering heat from a molded product and / or the machine in which the product is molded and applying the recovered heat to resin prior to molding. More specifically, this invention conserves energy by recirculating heat captured from the molded product and / or the molding machine to pre-heat the raw resin molding material, before the raw resin material enters an extruder or a molding apparatus.BACKGROUND OF THE INVENTION[0002]Molded products, such as plastics, and the like, have been known for decades and are used, inter alia, for product packaging, product presentation, material storage, and the like. Because of their widely-varying nature and characteristics, energy efficient methods of producing these items are a necessity. Of particular interest are methods to quickly cool a molded product, particularly within the context of manufacturing facilities.[0003]Previous methods of cooling, while effective i...
