What are ball plungers used for?

Ball plungers are tiny tools used in different areas to help with precise positioning or locking. They have a spring-loaded ball inside a housing. When the ball is pressed, it extends, and when released, it retracts. They are commonly found in industries like manufacturing and electronics. They are useful for tasks such as aligning parts, holding them in place, or creating a detent mechanism for secure positioning.

What material is ball plunger?

Ball plungers are usually made from different materials depending on their specific use. The most common materials are stainless steel, hardened steel, brass, and plastic. Stainless steel is resistant to rust and very strong. Hardened steel is tough and can withstand wear and tear. Brass is used when electrical conductivity is important. Plastic ball plungers are lightweight and used for less demanding tasks. The material choice depends on factors like strength, durability, and the purpose of the ball plunger.

What is the standard size of a ball plunger?

The standard size of a ball plunger can vary depending on the manufacturer and application. However, they generally come in different diameters and lengths. Common diameters range from 3mm to 20mm, while lengths can range from 10mm to 50mm or more. These sizes are widely used, but it's important to note that specific industries or applications may have their own standard sizes based on their requirements.

How much pressure does a plunger create?

The amount of pressure a plunger creates depends on various factors, including its design, size, and the force applied to it. Plungers typically generate pressure by compressing air or liquid trapped within a confined space. The specific pressure created can vary significantly. In household use, a plunger can create enough pressure to unclog a drain. However, in industrial applications, specialized plungers can generate much higher pressures to perform tasks such as hydraulic or pneumatic actuation.
