Appl. No.:

09/821900

Inventors:

Ronald Thomas - Chesterfield Township MI
Nicholas Pitstick - Xenia OH

Assignee:

Alliance Systems, Inc. - Chesterfield MI
Composite Technologies, Inc. - Dayton OH

International Classification:

B29D 2200

US Classification:

264572

Abstract:

A method for the compression molding of a plastic article is provided. The method includes the steps of loading plastic material, that is preferably unheated, into a two piece molding chamber having at least one heating element, closing the molding chamber, and heating the plastic element. The method further includes the step of injecting fluid, for example air, into the plastic material to create at least one cavity within the plastic material. The air may be injected directly into the plastic material, or it may be injected along an upper surface of the chamber. Upon injection of air into the at least one cavity, a portion of the plastic material is forced to exit the chamber.

Ronald Thomas - Chesterfield Township MI

Assignee:

Alliance Systems, Inc. - Chesterfield MI

International Classification:

B29D 2200

US Classification:

264572

Abstract:

The present invention provides a process for fluid assisted injection molding comprising the step of providing an injection molding apparatus having a mold body that defines a mold cavity. The process further comprises the steps of supplying a quantity of fluent plastic to the mold cavity, followed by injecting a fluid into the mold cavity. The fluid forms an expanding fluid pocket in the mold cavity, driving plastic to the furthest recesses of the mold and ensuring a smooth surface finish of the final molded product. A reservoir is selectively connectable to a plastic injection runner, and can be opened to the runner to receive molten plastic ejected by the introduction of the fluid to the mold cavity. When the reservoir is thusly connected, the pressure of the fluid forces the plastic through a supply passage, in a direction substantially opposite to its initial injection direction.

Appl. No.:

10/411738

Inventors:

Ronald Thomas - Chesterfield MI, US

International Classification:

B29C045/16

US Classification:

425/130000

Abstract:

An injection molding apparatus is provided that comprises a molding tool having a mold cavity, a source of pressurized gas, and a nozzle with a reciprocable pin, the pin valving gas injection into the molding cavity. A gas valve is positioned adjacent the nozzle, the gas valve selectively connecting the gas source with the nozzle. A nozzle having a reciprocable member for valving fluid injection in an injection molding apparatus is also provided. The nozzle includes a seal comprising a compressible elastomeric member and a sleeve, the reciprocable member slidable in the sleeve. Compression of the elastomeric member deforms the sleeve, creating a fluid seal with the reciprocable member.
