The smallest type of spring in the world

We developed the smallest type of spring in the world. It has a measurement of only 14μ in wire diameter and 80μ in external diameter, and even a five hundred of them can occupy a single square inch of space.

The microscopic spring is made of high-strength ultra fine fibers (Toss Micron) and the spring’s external diameter of 14μ is more like a fiber than metal. The spring reacts quickly to the slightest of external stimulus such as temperature and sudden change in humidity, and even breath. We had a difficult time manually creating a creating while looking at it under a microscope and setting it to a coiling machine.

Smaller than a pin head, this spring is an integral part of certain medical devices.

About us

Company details

We have the capacity to produce springs for a variety of applications. We manufacture springs of various sizes and materials for multiple applications.  

The capability to manufacture a wide range of products is our strongest point. In addition, we have also an advantage in our products that are not only made of difficult-to-process materials such as Tungsten and Titanium with a wire diameter of 14μ to 12mm, but we also create a difficult balance between materials and shape. While 4 up to 20 are considered as optimal in D/d (mean diameter / wire diameter) , we have managed in mass manufacturing unique-shaped springs with a minimum and maximum D/d levels of 2.3 up to 75.

We are particularly famous for our small springs. The 14μ variety is the smallest in the world, using a wire barely visible when threaded into the spring-making machinery. Smaller than a pin head, these springs are an integral part of certain medical devices.

We provide custom springs of all types and sizes including the world's smallest - we are your partner in spring production design and development.
