Abstract
Molded articles that have a surface coating, as well as, methods and systems of producing the same are provided. The type of surface coating is selected to provide the article with certain desired properties. In general, the methods involve applying a coating to a mold surface, for example using a thermal spray process, and then molding an article in the mold. The coating is transferred to the surface of the molded article during the molding process.
Claims26
A method of forming a composite article comprising:
- thermally spraying a first material on a surface defining a mold cavity;
- introducing a second material into the mold cavity;
- and
- recovering a composite article from the mold cavity, the composite article comprising the second material and having a coating comprising the first material.
1 more element
An composite injection molded article comprising:
- a plastic body portion having a softening temperature of less than about 250 degrees C.;
- and
- a coating formed on at least a portion of the plastic body portion, wherein the coating comprises a material selected from the group consisting of a ceramic, a metal and a cermet,
- the coating having a Rockwell C hardness of between about 30 and about 75.
1 more element
A system of forming a composite article comprising:
- an injection molding apparatus including a mold having a first mold half and a second mold half that define a cavity therebetween when the mold is in a closed configuration;
- and
- a thermal spray apparatus designed to extend between the first mold half and the mold half when the mold is in an open configuration.
