Welding processing technology

In 1956, we developed an automatic AC welding machine that was considered technically impossible, enabling welding with excellent strength and accuracy. In particular, welding of high melting point metals such as tungsten has earned us a high reputation. It is mainly used as an electrode for optical devices such as neon tubes and strobes and is also used for sensors using the characteristics of dissimisional metals.

Resistance welding processing

The resistance welding technology that is the foundation of our technology began with the in-house development of an automatic AC welding machine that was considered technically impossible in 1956. This automatic machine enabled excellent welding in both strength and accuracy. It welds materials with high melting points such as tungsten and is used for various sensors, neon tubes, strobes, etc. that take advantage of the characteristics of different metals.

Advantage of the Resistance Welding in comparison with the soldering

Because it does not take much time to weld, it is possible to mass-produce faster.

There are fewer materials to use.

Welding strength is stronger

Laser welding processing

Since around 2000, laser welding technology has been developing new technologies to manufacture cold cathode tube electrode leads used in LCD TVs and other applications. Recently, we have also applied it to welding snaps used as fishing equipment, and we are actively working on industries other than electronic components.

Advantage of Laser Weld

It can be welded very beautifully by a low distortion(There is little welding transformation)

High speed and welding penetration depth is possible

There is little welding fever influence

Forming processing

The forming process is to undergo crushed processing, bending processing, and microfabrication processing such as tiny holes, and then we respond to the customer’s request and deal from caulking band plates and welding processing to packing with arranging. It is used for quartz oscillators, condensers, vehicle-mounted headlights, and so on.

The Strength of our Forming

Our own forming machines are designed and assembled in-house, so the costs are lower in comparison to the press.

We have installed an image inspection machine on the production machine and are carrying out a total number of inspections.

Forging processing

We developed a header machine in-house in 1964. Today, the technology that made possible the processing of 0.05mm headers is also making possible more complex processing and is being used around the world for ceramic packages and LSIs with multiple pins.

Advantages of Headers Compared to Cutting

Less(low) material loss

Fast(quick/rapid/high) production turnover

High(strong) strength(High intensity)

Advantages of our header processing

Our header processing specializes in fine processing

Recent achievements include the processing of headers with a pin diameter of 0.05mm.

Fine Cut processing

Our wire shearing is characterized by mass production with ultra-high-speed shear and fine cutting that flattens the shear section with our original development shear method.

Compound processing

In addition to single-processing production of welding, forming, forging, and fine cutting, we also perform composite machining that combines each process, the number of metal processing element technology will increase further, and plate, cutting and Ag brazing will be added as a lineup.
By performing one-stop composite processing, we propose various advantages to our customers, such as quality improvement, shortened delivery time, and cost reduction.
