Brazing

What is brazing?

Brazing is a bonding method of joining either various metals or ceramic materials together by melting a brazing filler material to create the bond. This filler has a lower melting point than the materials bonded.

Features of brazing at Metal Technology Co. Ltd.

01. Experience and know-how

  • Over a considerable amount of time we have collected an enormous amount of brazing data both local and international creating an extensive brazing database.
  • Our experience in highly demanding areas such as the aerospace industry, the automotive industry, with semiconductor materials, LCDs, electronic devices, and precision devices is extensive and trusted.

02. Outstanding technology

  • We can simulate the bonding process to predict changes in shape and structure throughout the process in advance. We can then apply this data to the actual bonding process to offer safer, higher quality bonding of products with trusted results.
  • We can provide stress analysis, thermal conductivity simulation, analysis for bonded surfaces, and strengthening of bonded parts from room temperature to higher temperatures.

03. High quality

  • We have established a highly effective quality assurance system for bonding, including helium leak checks, ultrasonic testing for bonding conditions, metallurgical inspection, and strength testing to mention a few.

04. Leading equipment in Japan

  • We have several vacuum furnaces at each plant with a maximum size of 2,000mm. We also have several vacuum hot presses with a maximum working zone of 1,200mm x 2,200mm. Our equipment enables us to bond large surface areas and large sized parts which other manufacturers are unable to accommodate. In particular, for the bonding of large surface areas we have equipment which is able to apply pressure equally to the whole brazed area which is a vital aspect of the process.

Welding

What is welding?

Welding is a fabrication or sculptural process that joins materials, usually metals or thermoplastics, by causing fusion, which is distinct from lower temperature metal-joining techniques such as brazing and soldering, which do not melt the base metal. Heat or pressure, or both are added to produce a weld. If needed, appropriate materials are added to aid or support the weld.
