摘要:
The present invention relates to a hybrid process for producing molded plastic articles by reinforcing the walls thereof through the injection of a foamed thermoplastic material, thus increasing the thickness of the wall in previously determined zones in order to improve the mechanical characteristics thereof. According to the invention, said hybrid process comprises to strengthen previously defined zones of the plastic articles formed by any of the already known processes, such as: injection, extrusion, extrusion-blowing, injection-blowing, thermoforming, roto-molding, or any combination thereof; and afterwards the injection of a foamable thermoplastic material to fill up said strengthening predesigned zones.

摘要:
A pallet is formed from a thermoplastic material of the polyolefin type, from two pieces, base and deck, that can be coupled to each other with fasteners therebetween. The base and deck are provided with posts each projecting in a direction towards the other and able to be coupled to each other in order to form hollow columns. The posts projecting from the base form the outer wall of a plurality of columns, and the posts projecting from the deck are located at the interior of the columns, forming the inner wall thereof and thus constituting a hollow passage between the outer and inner walls of the columns. The hollow space is filled up with a foamed material to provide a greater impact resistance and resistance to disassembly under normal conditions of operation. The pallet can be integrally recycled without the need to separate the components thereof.

This invention relates to an improved pallet formed from a thermoplastic material of the polyolefin type, from two pieces, base and deck, that can be coupled to each other with fastening means there between; said base and deck provided with posts projecting from each in a direction towards the other and that can be coupled to each other, in order to form hollow columns; wherein the posts projecting from the base form the outer wall of a plurality of columns, and the posts projecting from the deck are located at the interior of said columns, forming the inner wall thereof and thus constituting a hollow passage between said outer and inner walls of the columns; said hollow space is filled up with a foamed material to provide a greater impact resistance and resistance to the disassembling under normal conditions of operation. The employment of the same material to form the pieces to be coupled and the reinforcement packing provides that said pallet can be integrally recycled without the need to separate the components thereof due to the nature of the material.
