Features

This spring uses the repulsive force from compression against its tendency to return to its resting state. It is the most commonly used among coil springs. The basic shape is a cylinder in which the material is wound in a spiral; however, the coil diameter may be shaped like an envelope or a barrel in order to change its load characteristics. To increase the verticality of the springs, there is also a terminal treatment to suit the application, such as polishing both ends or releasing the terminals outward or inward.

With Advanex

Both prototypes and mass-production services are available from one design. “WEB Spring Calculation” is available on our website. In addition, we can respond immediately to the design upon request, If you let us know your basic requirements, we will support the design, to include a variety of suggestions. Advanex also possesses the world’s smallest machining technology for minimally sized compression springs used in probe pins, etc. We promise maximum support to our customers through our facilities and technological capabilities.

Technical introduction

Advanex’s processing technology is also spreading into the micro area. We have achieved world class processing for items such as coil springs with wire diameters of 0.03mm and an inner diameter of 0.09mm, as well as tapered springs and torsion springs that cannot be discerned by the naked eye. The average thickness of Japanese hair is 0.08mm as compared with the 0.015mm diameter of the “ultra-small spring” wire in the photograph. Although not visible to the naked eye, it has a clear “spring” shape. It is mainly used in semiconductor inspection equipment and contact probes.
