Compression Spring Set for Face Mask Machine

Product Inroduction
Compression Springs
A compression spring is an open-coil helical spring that offers resistance to a compressive force applied axially. Compression Springs are the most common metal spring configuration and are in fact one of the most efficient energy storage devices available. Other than the common cylindrical shape, many shapes are utilized, including conical, barrel and hourglass. Generally, these coil springs are either placed over a rod or fitted inside a hole. When you put a load on a compression coil spring, making it shorter, it pushes back against the load and tries to get back to its original length.
For compression spring inquiry, please send us specification: wire diameter, outside diameter or inside diameter or mean diameter, number of coils or free length with pitch size.
If you don’t know how to design a spring or lack of the information which is required, it's ok. Please contact our sales team directly, we will provide you with most suitable suggestion for your products.
