Compression springs are designed to resist compressive forces. When a load is applied, the spring shortens, storing mechanical energy that is released when the force is removed.
Extension springs are designed to absorb and store energy when pulled apart. With tightly wound coils and a built-in initial tension, they return to their original shape once the force is released.
| Criteria | Compression Spring | Extension Spring |
| Load Direction | Handles compressive or “pushing” forces | Handles tensile or “pulling” forces |
| Coil Configuration | Open spacing, compresses under load | Closed spacing with preload for initial tension |
| Common Uses | Energy absorption, load support, shock resistance | Retraction, return force, secure attachments |
| Custom Options | Multiple shapes and end types, engineered per need | Variety of hooks, loops, or custom end designs |
Selecting between compression and extension springs comes down to force direction, performance requirements, and environmental conditions. For projects that demand more than an off-the-shelf solution, we provide:
Automotive systems rely on thousands of engineered mechanical components working in precise coordination. Among the most critical—yet often overlooked—are springs and wire forms that control movement, maintain force, and ensure reliable mechanical function throughout a vehicle’s lifecycle.
In modern medical device manufacturing, every component must meet strict demands for precision, biocompatibility, and reliability. Among the often-unsung heroes behind life-saving instruments and implants are wire forms — intricately shaped pieces of metal wire that deliver functionality, structural integrity, and performance consistency.
In precision metal stamping, a part is either right—or it is rejected. There’s no middle ground when components have to fit, flex, and perform reliably in critical assemblies. That’s why quality control is at the center of every successful precision metal stamping process.
