Product Description

Ball Plungers are devices that enclose a spring in a threaded capsule and provide a means of applying accurate and repeatable spring end forces through a ball or rounded nose. Also known as a Spring Loaded Device (SLD), allows repeated end force inaccurate locating, indexing or positioning applications.

Some of our product range includes molds with columns and spherical plungers.There are good standards of durability, reliability, and performance.

The Ball plunger is mainly used in the mold and is used on the slider to simply lock the return movement. The ball plungers we offer have advantages over most other products because they have a sleeve head for greater force, rather than a chute for the screwdriver, which has a greater chance of sliding. Encapsulating the spring in the valve body has several advantages over standard unprotected springs, such as quick and easy installation, the lateral force on the assembly, and repeatability throughout the life of the plunger The end force and extension.
