Capable of lightweight and minimizing volume

Coiled wave springs can generate large spring constants with thin and narrow materials, thus reducing weight and minimizing the volume.

Reduction of Side Forces

Coiled wave springs can reduce the excessive force in its horizontal direction (radial force) because of its few fluctuations of the center axis when compressed.

Stability against movement (When movement is severe)

The spring constant of coiled springs is relatively small and needs large deflection, thus it is suitable for dynamic use. On the other hand, coiled wave springs are not suited for applications in dynamic because of its high spring constant. Also, the friction and wear caused by contact with each wave should be considered.

Spring Rate (Strength and Flexibility)

Coiled springs can fit its spring constant by adjusting wire diameter and active turns easily. But coiled wave springs need to make a prototype model in order to confirm the final specification because coiled wave springs have a discrepancy between calculated and measured values.

Efficient Management of Inventory
Introducing an original filing system for our customer's orders

Our system for managing and logging your orders is entirely original and self-produced. We keep a track record of all your orders with a product number, the materials used, dimensions with drawings, and a manufacturing process with traceability. You can even monitor the inventory to keep track of your future orders. Nearly all the steps for processing is managed by barcodes, leaving little room for mistakes or mishandlings.
