Coiling Technologies is a leading compression spring manufacturer specializing in custom compression springs designed for high-performance, high-load, and mission-critical industrial applications. Engineered to deliver precise force and durability under compression, our springs are custom-built to meet exacting specifications, with expertise in large compression springs and exotic materials like Inconel and Rene 41.
With decades of experience supporting sectors such as oil & gas, military, construction, and manufacturing, we supply compression coil springs engineered to withstand extreme loads, corrosive environments, and high-temperature conditions. Whether you require prototype development or full-scale OEM production, Coiling Technologies delivers spring solutions that meet the most stringent industrial demands.
What Are Compression Springs?
Compression springs are open-coil helical springs designed to oppose compression forces. When axial pressure is applied, they compress and store mechanical energy. Once the force is released, they return to their original shape, making them vital components in vibration isolation, load bearing, shock absorption, and maintaining force between components.
These springs can be manufactured in a wide range of shapes, sizes, and configurations—including conical, barrel-shaped, or hourglass—to accommodate specific design constraints or performance needs.
Custom Compression Spring Capabilities
Coiling Technologies produces custom compression springs tailored to your engineering drawings, performance tolerances, and material requirements. Unlike off-the-shelf solutions, we engineer each spring to meet the dimensional accuracy, fatigue resistance, and environmental resilience your application demands.
