Quality control inspectors use a variety of tools to ensure that all the products manufactured by the company are within the limits designated by the designers. A quality control inspector checks every aspect of the production process, using a different tool to accomplish the inspection. Manufactured goods such as textiles, clothing, machine parts or electronics are inspected with some type of tool or tools.
An air gage is a tool used by the quality control inspector to determine several aspects of a part or product. The air gage can determine the inside or outside diameter or dimensions of a part, find any leaks in a product, determine the taper requirements, and even check the depth or thickness of steel. Air gages come in different types such as hand held air gages, assembly line air gages that automatically check the part, bench type air gages in which the inspector places the part into the air gage, and some air gages are automatic but need to have the part placed into it before it checks or inspects the part.
Quality control inspectors use bore gages to measure the dimensions of a part, any grooves inside the part, degrees of taper or any steps located inside the part. The bore gage comes in many styles and types. Quality inspectors use a mechanical gage that has moving parts to measure the inside of a part. Electronic bore gages use electrical current to test and read the inside dimensions of a component part. Air bore gages are similar to air gages, but only test the inside of a part.
The quality control inspector uses different size calipers to measure every part of the product; it does not matter if the part is square, round, oval or any other shape. The calipers are a slide-measuring device that quality control inspectors read and record the information on an inspection list to ensure the part is within tolerances. Calipers are in the English measurement or in metric depending on the tolerances original design.
Quality inspectors use a color sensor device to determine the proper color mixture of clothing, textile or painted part. The correct color mixture is essential with every color change, and the inspector uses the color sensor to ensure every product piece is the same color. This sensor generally uses only three basic color models: red, blue or green. These three colors can create most colors, and the color sensor checks how much of each color is in the product to ensure a consistent color scheme.
