A pneumatic clamp is a device that uses compressed air to hold objects securely in place. It operates by using a cylinder that moves a clamping arm, allowing for quick and efficient fastening of materials. These clamps are commonly used in manufacturing and assembly processes where speed and precision are essential. Pneumatic clamps come in various designs, including toggle clamps and cylindrical clamps, to suit different applications. They are favored for their ability to apply consistent pressure and reduce manual labor, making them ideal for tasks such as woodworking, metalworking, and automotive assembly.
