Spring plungers are spring-loaded devices used in molds, fixtures, assemblies, and jigs to save time and manpower. They provide accurate spring end force and are easier to install than bare springs. Caution is needed during installation, but they are long-lasting. Different types of spring pistons are available, including those with two spring pressures and nylon noses for softer materials. Metric spring loaded pistons offer accuracy, consistency, and reliability.
Spring plungers, also known as spring loaded devices (SLDs), are devices that enclose a spring within a threaded capsule. Tool engineers often insert spring plungers into their tools to save time and manpower, as they ensure positive, controlled spring tension when used in molds, fixtures, assemblies, and jigs. They also provide an accurate spring end force, which helps push through a ball or nose nose inside a tool or fixture. This allows a tool or piece of equipment to work more efficiently.
Installing springs into fixtures can be difficult, as they deform easily. Spring loaded plungers, on the other hand, make this job much easier, because the spring is securely encapsulated inside. These devices are best installed with the help of a screwdriver, hex key, or spring/ball plunger wrench.
While spring loaded plungers are easier to install than bare springs, it is still important to use caution during installation. The body of a plunger is hollow and, therefore, not strong enough to withstand a great deal of pressure during installation. They are also not the same size as a bolt or screw head. However, they are long lasting because lateral forces are applied to the assembly once in place.
Some spring pistons have two spring pressures. It is easy to distinguish between these and the standard versions, as the standard variety has a white nose and the duel spring pressure variety has a black nose. Some varieties also have a silver nose, indicating that they hold light pressure.
Spring pistons with nylon nose are also available. These are used when working with softer materials, such as brass or aluminum. They have higher strength than other spring loaded pistons, providing world class wear resistance and minimal deformation.
Metric spring loaded pistons offer accuracy, consistency and reliability. Not only do these ensure perfect alignment at any extension, but they also feature a hardened steel and black oxide body and case noses.
