Our 27μｍ outer diameter coils have been certified by the Guinness Book of World Records as “the Smallest commercially available metal coil”.

We offer rare and precious metal coiling services, working with rare metals and difficult to cut metals such as W, Mo, Ta, Re-W, SUP, SUS, Pr, Au and more.

Our production capabilities include, but are not limited to Single Coils; shaped like a spring, Double coils; wound over a single coil, Variable pitch coils; with custom spacing between the windings, and legged coils; with a connecting wire.

Types

We offer various grinding capabilities for our customers. Sharpening of the tip, D-cut and H-cut processing as well as a combination of these processes. We are also able to offer Flattening or Round chamfering of the tip.

Types

We also provide NC lathing of difficult to machine metals such as tungsten and molybdenum. We are experienced in other complex machining capabilities such as Tip machining, groove machining and a combination of additional services such as welding different parts to machined components.

Types

We perform precision cutting of continuous coils. Other than Shear cutting and grinder cutting, we also offer laser cutting, which involves firing a focused laser beam to cut the edges, and utilization of wire saws for fine cutting.

Types

We perform welding of different refractory metals, and welding of refractory and general metals. A distinctive feature of our welding is that it utilizes the difference in melting points to minimize the brittleness of the refractory metal weld.

The welding method is chosen based on the part shape, and type of metal. Laser welding, resistance welding and brazing are used depending on the situation. By utilizing these methods, we achieve high-quality and strong welds.

Types

We specialize in the assembly of components that require high assembly precision such as electron emission filaments, thermionic filaments, stem and grid parts welding, press fitting of air purifier discharge needles to a resin or metal base, electric scalpel electrode precision parts, and pipes.

Types

Our company specializes in the heat treatment of tungsten coils, filaments, as well as various electronic components, including reduction treatment by hydrogen annealing, and degassing treatment by vacuum processing.

Types

We offer various techniques for surface treatment such as heat treatment and chemical treatment. We are also capable of coating metal surfaces with different materials.
