A pneumatic press is a type of mechanical press that uses compressed air to generate force for pressing operations. It works by compressing air from a compressed air source and then directing it through a control valve to a cylinder, where it acts against a piston to produce the required force. Pneumatic presses are commonly used in manufacturing operations for pressing, punching, forming, and stamping a wide range of materials including metals, plastics, and composites. They are favored for their ease of use, speed, and versatility, and can be found in a variety of industries including automotive, aerospace, and electronics.
