Approach to New Fields (Aircraft Industry and DLC Film Deposition)

HOME > Approach to New Fields (Aircraft Industry and DLC Film Deposition)


Kaibara is working on two new business fields, advancement into the aircraft industry and the research and development of DLC film deposition.

Advancement into the aircraft industry

We have mainly been casting and machining copper alloys. As a challenge for the next generation, we have recently advanced into the aircraft industry in order to gain the know-how, experience, and knowledge of the special machining of materials other than copper alloys.

We obtained JIS Q9100 certification for a quality management system standard of the aerospace industry. We introduced computer-aided design and computer-aided manufacturing (CAD/CAM) technologies, leading-edge large-scale processing equipment, automatic transfer equipment, and large inspection equipment, and established state-of-the-art factory facilities.

Utilizing know-how and equipment accumulated in this field, we would like to respond to a wide variety of customers’ requests not only for aircraft parts but also for hard-to-cut materials precision machining and 5-axis machining in the future.

We achieve the machining of not only aircraft parts but also other parts according to each customer’s needs in our factory facilities with state-of-the-art equipment.

Feel free to contact us if you have any requests.

Research and Development of DLC Film Deposition

Kaibara is engaged in the research and development of DLC film deposition with excellent lubricity.

DLC stands for diamond-like carbon, an amorphous hard film with an intermediate structure between diamond (sp3 structure) and graphite (sp2 structure). The properties of the film change variously, depending on the proportion of the sp3 structure and sp2 structure, the content of hydrogen, the addition of other elements, and the manufacturing technique.

Diamond (sp3 structure)

DLC (Amorphous structure)

Graphite (sp2 structure)

Characteristics of DLC

  • High hardness: Vickers hardness of 1000 to 8000
  • Low friction and excellent wear resistance
  • Excellent chemical resistance and corrosion resistance
  • Excellent environment resistance
  • A barrier property against ultraviolet rays and gases

There are various DLC film deposition methods, but Kaibara introduced Kurita Manufacturing’s PBII-R1000, a plasma-based ion implantation and deposition (PBII & D)apparatus.

Characteristics of PBII & D

  • The work piece is used as a plasma generation source.
  • Plasma is generated along the shape of the work piece; film can be formed even in complicated shapes.
  • Processing is possible at extremely low temperatures (~40ºC); aluminum, rubber, and plastic can also be formed.
  • No transport of plasma isnecessary for vacuum equipment, thus improving plasma use efficiency.
  • Possible to form a film with high followability in response to substrate deformation, with soft, low residual stress.

Kaibara employs the above characteristics and conducts research and development of films that meet customer needs, regardless of the purpose of the frictional applications.
