J goodtech

A front-line company of electron beam/laser welding also involved in spacecraft manufacturing

Specialized in electron beam welding since its establishment, the company now conducts consigned processing work with the use of electron beam/laser. We are engaged in precision machining in a variety of industries, ranging from Spacecraft “Hayabusa 2”, space stations/rockets, jumbo passenger aircrafts, high-performance racing engines to items for automobiles, mobile devices and medical equipment.

  • Business Outline

    Consigned processing with electron beam/laser. We conduct processing work for a wide range of industries that require high-quality and high-precision processing, including automobile, aerospace, medical equipment, industrial machinery, semiconductor and electronics. We also sell made-to-order laser processing systems, give technical guidance thereof, and develop and sell our own brand products (product example: laser cleaning devices).

  • Product Strength

    Electron beam/laser processing enables welding with less distortions and high-quality processing free from cracks and burrs compared to other processing methods. This processing method thus makes overall cost reductions possible by leaving out some processing procedures. It is also possible to process complicated shapes. Also, since electron beam welding is characterized by its very high energy density, it can join dissimilar metals that cannot be joined with other methods. Further, the electron beam welding can make products lighter and more compact and realize cost cutting. Laser processing can perform drilling, cutting and surface modification processing. Ultra-short pulse laser can perform beautiful nano-level fine processing, while reducing the thermal effects as much as possible.

  • Company Strength

    Our company is always equipped with state-of-the-art equipment in the field of electron beam welding machinery and laser processing machinery. Taking advantage of our high processing technology unparalleled with other companies, we conduct precision machining in a variety of industries, ranging from Spacecraft “Hayabusa 2”, space stations/rockets, jumbo passenger aircrafts, high-performance racing engines to items for automobiles, mobile devices and medical equipment. We cover the processes from prototyping to mass production. We can also conduct processing work with the attendance of our customers. We also aim to enhance our capacity to propose solutions by establishing partnerships with excellent small- and mediem-sized companies across the country in order to respond to the requests of large companies, which our company alone cannot meet.

  • Company Structure

    We will create a position in charge of new business partners within the sales department as an information desk for large companies and overseas companies. As for technical consultations, personnel in charge in the engineering and sales departments respond to them, including visiting the customers in person as needed as a way to respond to their inquiries in a sincere manner. The sales manager takes leadership in responding to new customers, including overseas business partners, at the same time striving to collect and manage relevant information.

Message from President
Kunika Ueno

Established as a company specialized in electron beam welding in 1977, our company has become the company that has the largest market shares in the Japanese market of consigned processing with electron beam and laser. I was appointed as president in 2012 succeeding the founder. Positively interpreting changes as progress, I would like to gradually develop the company with the corporate statement “Keep moving forward!!” As a first step, we built a new factory in Fukuoka Prefecture in order to firmly establish our profit base and respond to the needs of emerging markets such as Southeast Asia. I would like to develop new businesses with possible alliances with other companies, while developing technologies tailored to the needs of overseas markets.
