Features

The process specializes in thin-walled deep drawing, and can handle drawing depths of up to 37 times the outer diameter. We are also aggressively taking up the challenge of processing new materials, including brass, red copper, phosphorous deoxidized copper, tough pitch copper, beryllium copper, phosphor bronze, nickel-nickel, iron (SPCE, SPCC), stainless steel (SUS), plated steel plates, aluminum, nickel, and cladding. Today, we manufacture components in a wide range of industries, including the medical industry, telecommunications equipment, automobiles, and audio-related industries.

With Advanex

Products previously believed to be only machinable by cutting and pipe machining can also be commercialized by transfer machining and press machining. For example, we switched to transfer machining for products that had been machined, resulting in a four-fold increase in productivity and a substantial reduction in costs.

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.

Features

Among coil springs, exension springs are widely used with compression springs. They are used in applications in which a load in the tensile direction, against a compression spring. The initial tension is effectively utilized, and it is generally made into close contact winding in order to reduce the space. Hooks for receiving loads are usually raised at both ends, but their shapes are designed in a variety of ways depending on the application.

With Advanex

Both prototype and mass production services are available for a single design. “WEB Spring Calculation” on the website is available. In addition, we can immediately respond to design upon request. If you can tell us your basic requirements, we will support the design, including a variety of proposals. Especially in cases where the stress applied to the hook portion of a exension spring is large, and there are some examples of breakage there. Advanex uses a mechanical processing machine and an NC multi-forming machine separately for hook shapes that are designed according to the application, including solutions for stress relaxation, to meet the requested shape.
