1. A molding system, comprising:
- a material supply system that comprises a gas introduction device, wherein the material supply system further comprises components that are operable to supply a material in a liquid phase to the gas introduction device, and the gas introduction device is operable to introduce a gas into the material in the liquid phase; and
a mold coupled to the material supply system, wherein in the mold is operable to receive the material, in the liquid phase and including the introduced gas, into a first mold volume that is defined by the mold, and the mold is further operable to compress the material located in the first mold volume into a second mold volume that is defined by the mold such that at least some of the introduced gas in the material is removed from the material.

Abstract
A method for molding a part includes introducing a gas into a material that is in a liquid phase. A mold is then positioned in an intermediate position The material, in the liquid phase and including the introduced gas, is then injected into the mold. The mold is then positioned in a closed position such that the material that was injected into the mold is compressed by the mold.

16. A method for molding a part, comprising:
-
providing a mold that comprises a first section and a second section, wherein the first section is moveable relative to the second section; moving the first section relative to second section to define a first mold volume between the first section and the second section; injecting a liquid phase material that comprises a plurality of gas bubbles into the first mold volume; and compressing the liquid phase material that comprises the plurality of gas bubbles by moving first section relative to the second section to define a second mold volume that is smaller that the first mold volume and that comprises a thin-wall section and a rib section, wherein the compressing the liquid phase material further comprises removing at least some of the plurality of gas bubbles from the liquid phase material that is located in the thin-wall section. - View Dependent Claims (17, 18, 19, 20)
