A plunger is a mechanical component designed to secure and position workpieces in machinery. It consists of a cylindrical body housing a spring-activated ball or pin, which retracts under pressure and extends when released, enabling easy integration into various devices without custom parts.
Plungers are versatile tools used across industries—from food production to semiconductor manufacturing—for securing workpieces to machinery. Their ability to provide precise positioning makes them indispensable in applications requiring high accuracy, such as in the alignment of drill holes or the positioning of levers.
Plungers operate on a simple yet effective principle: a spring mechanism inside the plunger exerts force, securing the workpiece in place. This mechanism allows for easy attachment to machines using threaded sides or pressure insertion, with materials chosen for durability and performance.
Ball plungers feature a ball tip for smooth operation, ideal for quick positioning tasks. The ball retracts under load, allowing for easy adjustment, and extends under spring force for secure positioning.
Pin plungers, with their longer stroke capacity, offer adjustable positioning for tasks requiring greater precision. They are commonly used in machinery for ejecting parts or securing levers.
Index plungers are perfect for tasks requiring precise alignment, such as attaching parts. They come in retractable and lockable designs, with tapered or spherical tips to fit specific alignment needs.
Key performance metrics for plungers include stroke length, and minimum and maximum load capacity, essential for selecting the right plunger for your needs. The load capacity, measured in Newtons (N), indicates the force the plunger can handle.
The spring constant, calculated from the load capacity and stroke length, helps determine a plunger’s suitability for light or heavy-duty applications. Understanding this value ensures the plunger matches the operational demands of the machinery.
