Abstract
A method and apparatus for anodizing a component. The component is placed in a container having first and second seal members that seal an annular surface of the component to be anodized. The first and second seal members, the annular surface of the component, and an inner surface of the container form a reaction chamber that holds a reaction medium therein. The reaction medium is supplied to the reaction chamber through a supply passage formed in the container. The reaction medium is drained from the reaction chamber through a drain passage formed in the container.
Claims14
An apparatus for anodizing a component comprising:
- a container having a receiving hole for receiving the component into the container;
- first and second seal members for sealing an annular cylindrical surface at a middle portion of the component such that a reaction chamber is formed between the container, the first and second seal members, and the annular surface of the component;
- a supply passage in the container for introducing a reaction medium into the reaction chamber;
- and
- a drain passage for draining the reaction medium from the reaction chamber,
- wherein the container includes a passage plate having an opening for the component to extend through, wherein the passage plate includes a supply groove and a drain groove opening into the reaction chamber.
An apparatus for anodizing a component comprising:
- a container having a receiving hole for receiving the component into the container, and
- first and second seal members for sealing an annular cylindrical surface at a middle portion of the component such that a reaction chamber is formed between the container, the first and second seal members, and the annular surface of the component,
- wherein the first and second seal members are placed on flange portions formed in the container, and
- further comprising:
- a push mechanism for compressing the first and second seal members so as to seal the outer surface of the component, the push mechanism including a movable sleeve disposed between the component and the container, and a push rod disposed in the container for pushing the sleeve.
