Method of producing a throttle assembly

A method of producing a throttle assembly, the method comprising:

• inserting a first core into a mold portion to form a first throttle component cavity between the first core and the mold portion;
• providing a first thermoset plastic material into the first throttle component cavity to form a first throttle component including a window and a sealing seat around at least a portion of a perimeter of the window;
• removing the first core from the mold portion while maintaining the first throttle component positioned within the mold portion;
• inserting a second core into the mold portion to form a second throttle component cavity between the mold portion, the first throttle component, and the second core;
• providing a second thermoset plastic material into the second throttle component cavity to form a second throttle component including a cover portion that substantially matches the window and a sealing surface around at least a portion of a perimeter of the cover portion, wherein the sealing seat acts as the portion of the second throttle component cavity that forms the sealing surface;
• removing the second core from the mold portion;
• removing the first throttle component and the second throttle component from the mold portion;
• at least partially separating the first throttle component from the second throttle component;
• and
• maintaining an association between the first throttle component and the second throttle component to facilitate subsequent assembly of the first throttle component and the second throttle component into the throttle assembly.
