The "spring index," also known as D/d (debaide), is a value that serves as a guideline for the difficulty of processing.

• Spring

By applying a setting process, it is possible to prevent the spring from sagging during use.

• Spring

Shot peening and setting processes improve the durability of springs.

• Spring

The Shin-Kin type winding machine can process wire diameters up to Φ10mm.

• Spring

Piano wire types "A" and "B" are widely used, but type "V" does not have good marketability.

• Spring

By lowering the spring constant, it becomes easier to manage the load at the specified height.

• Spring

To suppress the variation in moment (torque), the free angle of the arm is managed with a tolerance of ±2.5 degrees.

• Spring

The sensor controls the free height and suppresses load variation.

• Spring

We deliver in pallet packing to prevent entanglement.

• Spring

For tension springs with hook processing and torsion springs with arm bending processing, we recommend using type A (SWP-A) for better workability.

• Spring

We will quantify the balance of "just the right feeling" in the form of a moment.

• Spring

The right angle of the spring after grinding is managed according to internal standards with a precision of JIS Class 2 or higher.

• Spring

There are "spring type" and "valve spring type" in the iron-based spring material "oil-tempered wire."

• Spring

Special-shaped hooks not specified by JIS standards are also possible.

• Spring

By processing the initial tension to a lower level, we can reduce the impact on the moment (torque).
